      HERBERT SPENCER: PHRENOLOGY, 
        EVOLUTIONARY ASSOCIATIONISM, AND CEREBRAL LOCALIZATION
      It is very satisfactory to see how you and Bain, each 
        in his own way, have succeeded in affiliating the conscious operations of the 
        mind to the primary unconscious organic actions of the nerves, thus filling up 
        the most serious lacuna and removing the chief difficulty in the association 
        psychology.
      John Stuart Mill, 1864.
      To Spencer is certainly due the immense credit of 
        having been the first to see in evolution an absolutely universal principle.
      Add this sleuth-hound scent for what he was after, and 
        his untiring pertinacity, to his priority in perceiving the one great truth, and 
        you fully justify the popular estimate of him as one of the world's geniuses, in 
        spite of the fact that the 'temperament' of genius, so called, seems to have 
        been so lacking in him.
      William James, 1904.
      That the philosophical system of Spencer is an object 
        of derision is one of the few points on which all philosophers seem now to 
        agree.

      Early Phrenological Work and Social 
        Statics
      Bain represented the culmination of classical 
        associationism and brought it into relation with sensory-motor physiology. 
        Herbert Spencer's Principles of Psychology was published in the same year 
        that Bain's Senses and the Intellect appeared (1855), yet the two works 
        belong to different generations. Where Bain had enriched the association 
        psychology with a new interest in motion and provided it with an important 
        alliance with experimental neurophysiology, Spencer gave it a whole new basis in 
        evolutionary biology. It was Spencer's psychology of evolutionary associationism 
        and the conception of cerebral localization which he united with it, that 
        Hughlings Jackson applied to the nervous system. The views of Jackson and Bain 
        then provided the psychophysiological theory which David Ferrier developed 
        experimentally after the localized electrical excitability of the cerebral 
        cortex was demonstrated in 1870. It is only a slight exaggeration to say that 
        the work of Jackson and Ferrier can be deduced from the theories of Bain and 
        Spencer. Jackson's clinical work and Ferrier's experiments were acknowledged 
        applications of the conceptions of Bain and Spencer. An historical study of the 
        development of concepts of cerebral localization and its biological context 
        should therefore pay close attention to the sources of these conceptions as a 
        necessary prerequisite to an appreciation of their use in the clinic and 
        laboratory.
      Spencer's intellectual development shows the relations 
        among associationism, phrenology, sensory-motor psychophysiology, cerebral 
        localization, and the new basis for psychology in the theory of evolution. All 
        of these approaches came together in his early writings, providing a unique 
        opportunity to review previous work and to lay the foundations for the work of 
        Jackson and Ferrier. A close study of this period will also afford an 
        opportunity to indicate further developments of the conception of psychology as 
        a biological science which were raised in connection with Gall and were 
        significantly advanced by Spencer. These developments will be indicated, 
        although in the present study they will not be pursued in detail beyond Spencer.
      The connection between Gall's biological view of 
        psychology and Spencer's is not merely conceptual. Like Bain, Spencer derived 
        his initial interest in psychology from phrenology.[1] His biographer reports 
        that 'His letters show that he approached the study of mental functions through 
        the avenue of phrenology, his conclusions being reached, as he is more than once 
        careful to mention, not theoretically only, but by observation'.[2] In his  Autobiography, Spencer says,
      Between 1820 and 1830, phrenology had been drawing 
        attention; and there came over to England, about 1830 or after, Gall's disciple, 
        Spurzheim, who went about the country diffusing knowledge of the system. Derby 
        was among the towns he visited. Being then perhaps 11, or perhaps 12, I attended 
        his lectures: having, however, to overcome a considerable repugnance to 
        contemplating the row of grinning skulls he had in front of him. Of course at 
        that age faith was stronger than scepticism. Accepting uncritically the 
        statements made, I became a believer, and for many years remained one.[3]
      In 1842, when he was twenty-two, Spencer had his head 
        'read' by a reputable phrenologist, Mr J. Q. Rumball. Firmness, Self-Esteem, and 
        Conscientiousness were the largest prominences, and Mr Rumball commented that 
        'Such a head as this ought to be in the Church'.[4] The full delineation and 
        commentary are worth studying, as they are,
      1 I am indebted to articles by Jefferson (1960, pp. 
        35-44) and Denton (1921) for the initial impulse to look into the following 
        matters on Spencer.

      on the whole, unexceptionable. However, one friend 
        ventured the suggestion that 'he might have arrived at the same conclusion 
        without feeling your head at all'.[l] Spencer was not moved by his friend's 
        scepticism, 'Papers yield evidence that at that time my faith in phrenology was 
        unshaken.'[2]
      Between 1842 and 1846, his interest in phrenology was 
        very active indeed. He wrote memoranda on the faculties of Veneration, 
        Self-Esteem, and Love of Approbation, and made a design for an ideal head.[3] He 
        wrote to a friend in 1843, 'At present I am engaged in writing an article for  The Phrenological Journal upon the new theory of Benevolence and Imitation, 
        which we have talked over together'.[4] By this time Spencer's scepticism about 
        phrenology was beginning to manifest itself. The heretical article, advocated a new view of the functions of the organs, and it was rejected by Combe.[5] 
        However, it was accepted by a new periodical, The Zoist, founded by Dr 
        John Elliotson for the propagation of mesmerism.[6] 'Phreno-mesmerism[7] was at 
        that time the name of one class of the manifestations; and, by implication, 
        Phrenology was recognized as an associated topic. Hence, in part, I suppose, the 
        reason why Dr Eliotson [sic] accepted this essay of mine.’[8] The 
        article was published in The Zoist of January, 1844. Two other heterodox 
        articles advocating relocation of Amativeness from the cerebellum to the 
        adjacent cerebrum and suggesting that the 'ultimate function' of the organ of 
        Wonder was 'the revival of all intellectual impressions' or 'Revivisence' 
        appeared in the July and October numbers.[9]
      Spencer says of this period,
      Partially dissentient though I was concerning special 
        phrenological doctrines, I continued an adherent of the general doctrine: not 
        having, at that time,

      5 This rebuff was later used by phrenologists to 
        explain Spencer's subsequent hostility to their views, e.g. Hollander, n.d., I, 
        459. The members of the British Phrenological Society were still sensitive about 
        Spencer in the 1960s.
      6 Elliotson had been President of the Royal Medical and 
        Chirurgical Society, Lecturer at St Thomas' Hospital and Professor at the 
        University of London. He introduced the stethoscope into London. He was a famous 
        surgeon. However, his espousal of painless operations by mesmerism ended his 
        academic career. Phrenologists were grateful for the new ally and especially for 
        the aura of martyrdom which hung around him. The standard translation of Gall 
        was dedicated to him. He founded the London Phrenological Society and lectured 
        extensively on phrenology. (Hollander, n.d., 1, 342, 354, 357, etc.) Cf. 
        Spencer, 1904, I, 227, 246-7; Wallace, 1901, p. 180; Boring, 1950, pp. 119-23.
      7 This was the aspect of phrenology that had converted 
        A. R. Wallace. See above, pp. 44-5

      entered on those lines of psychological inquiry which 
        led me eventually to conclude that, though the statements of phrenologists might 
        contain adumbrations of truths, they did not express the truths themselves.[1]
      His active interest in phrenology can be traced as far 
        as 1846, when he set out to improve on phrenological technology.
      My interest in phrenology still continued; and thought, 
        occasionally expended upon it, raised dissatisfaction with the ordinary mode of 
        collecting data. Examinations of heads carried on merely by simple inspection 
        and tactual exploration seemed to me extremely unsatisfactory. The outcome of my 
        dissatisfaction was the devising of a method for obtaining, by graphic 
        delineations, mechanically made, exact measurements, instead of the inexact ones 
        obtained through the unaided senses.[2]
      A description and drawings of the 'cephalograph' which 
        he designed are appended to his Autobiography.[3] He intended to 
        publish its description in The Zoist, but a trial model had been badly 
        made. He did not pursue the matter then, and when he returned to it, he says, 'I 
        had become sceptical about current phrenological views, and no longer felt 
        prompted to employ a better instrument-maker'.[4]
      Spencer began reading in preparation for his first 
        book, Social Statics (1851) in 1846, and between then and 1848, he 
        abandoned his career as a railway engineer and decided to earn a living as a 
        writer. Social Statics sought to relate his views on the proper sphere of 
        government with general moral principles[5]; his attempts to argue a consistent 
        laissez-faire view of society were based on a biological theory of the structure 
        of human communities, in which social bodies were made analogous to the somatic 
        organization of men and other organisms. The argument of the book can be briefly 
        given in context with its relevance to the development of Spencer's views on 
        psychology and physiology.
      It was written as an attack on Benthamism[6] — 
        retaining the utilitarian standard of value but rejecting the active role of the 
        state in attaining the greatest happiness for the greatest number. State 
        regulation and legislation are seen as interference with Spencer's 'First 
        Principle': 'Every man has freedom to do all that he wills, provided he 
          infringes not the equal freedom of any other man.’[7] Men would 
        eventually come to do

      naturally what is best, even though a lengthy struggle 
        would be necessary. His position, which provided the rationale for the 
        individualist and ultra-conservative ideology of 'Social Darwinism',[1] leads 
        him to oppose such things as poor laws, state-supported education, sanitary 
        supervision, protection of the ignorant from medical quacks, tariffs, state 
        banking, and government postal systems. He opposes anything which he feels would 
        interfere with the free exercise of all of men's faculties. The duty of the 
        state is to protect equal freedom but never to interfere with it. He 
        claims that 'beyond its function of protector against external and internal 
        enemies, the State has no function: and . . . when it assumes any other function 
        it becomes an aggressor instead of a protector'.[2]
      His argument is based on a distinctly phrenological 
        view of man. The faculties are heterodox, but they are phrenological faculties 
        none the less. Consistent with the optimism added to Gall's views by Spurzheim 
        and Combe, they are extremely modifiable: 'The universal law of life is, that 
        the exercise or gratification of faculties strengthens them; whilst, on the 
        contrary, the curbing or inflicting pain upon them, entails a diminution of 
        their power.'[3] Each faculty grows by exercise and dwindles from disuse.[4] 
        Happiness results from 'the fulfilment of their functions by the respective 
        faculties'.[5]
      His conception of psychological phenomena departs 
        radically from that of the Utilitarians. He accepts the pleasure-pain principle 
        but not the normative psychology with which it had been traditionally linked by 
        the associationists. James Mill had elaborated Hartley's psychology to serve as 
        a rational basis for the legislative, economic, and social programme of the 
        Philosophic Radicals. The psychological view which he developed implied that a 
        common human nature led to a 'natural identity of interests' of the individuals 
        in society. Pleasure and pains could be scientifically determined and made part 
        of a 'felicific calculus'. From these calculations of a scientific psychology, a 
        legislative programme could be devised which created an 'artificial 
        identification of interests'[6] by means of the rewards and punishments which 
        the state dispensed. These two aspects of the Utilitarian programme are 
        contradictory; and Spencer's Social Statics was a symptom of this major 
        weakness. Spencer argues that if there is a common meeting ground of the 
        interests of individuals in society, it will manifest itself without

      the artificial sanctions of rewards and punishments by 
        the state. Moreover, he claims that the belief that such sanctions can be 
        effective is based on an erroneous conception of human nature. Reasoning 
        abstractly about the 'greatest happiness' only makes sense when talking about 
        the ideal man. Attempts at defining such a state are nonsensical where real men 
        are concerned. 'It is not then to be wondered at, if Paleys and Benthams make 
        vain attempts at a definition.'[l]
      The source of his objection is a phrenological view of 
        individual differences based on a faculty psychology.
      Man..... consists of a congeries of faculties, 
        qualifying him for surrounding conditions. Each of these faculties, if normally 
        developed, yields to him, when exercised, a gratification constituting part of 
        his happiness; whilst, in the act of exercising it, some deed is done subserving 
        the wants of the man as a whole, and affording to the other faculties the 
        opportunity of performing in turn their respective functions, and of producing 
        every one its peculiar pleasure: so that, when healthily balanced, each 
        subserves all, and all subserve each.[2]
      Complete happiness is the result of the exercise of all 
        the faculties,
      in the ratio of their several developments; and an 
        ideal arrangement of circumstances calculated to secure this constitutes the 
        standard of 'greatest happiness'; but the minds of no two individuals contain 
        the same combination of elements. Duplicate men are not to be found. There is in 
        each a different balance of desires. Therefore the conditions adapted for the 
        highest enjoyment of one, would not perfectly compass the same end for any 
        other. And consequently the notion of happiness must vary with the disposition 
        and character; that is, must vary indefinitely.[3]
      State action cannot take account of the myriad subtle 
        differences among individuals. It can only do harm to the happy, self-sufficient 
        man or prevent a man who has not achieved this state from doing so.[4] 'To do 
        anything for him by some artificial agency, is to supersede certain of his 
        powers-is to leave them unexercised, and therefore to diminish his 
        happiness.'[5]
      Turning from individual psychology to social relations, 
        Spencer proposes two reasons why men will act for the good of others without 
        needing the artificial restraints of state action. The first is the existence of 
        the faculty of the 'Moral Sense'. In his argument for such a faculty,

      Spencer reveals the detailed influence of phrenology on 
        his psychological thinking. Phrenological faculty psychology and craniology are 
        not mentioned explicitly, and he makes no acknowledgement of the interests which 
        had dominated his writing activity a few years earlier. However, in attempting 
        to uphold the Moral Sense doctrine in opposition to Bentham's condemnation of 
        the principle,[1] Spencer uses a phrenological view of the nature of man, which 
        he believes unequivocally establishes the existence of a Moral Sense. He also 
        tries to show that the Utilitarians fall back on the moral sense for the 
        foundation of their own doctrine.[2] His phrenological argument is that nature 
        does not leave the fulfilment of important needs to chance or to the care of the 
        intellect. 'Answering to each of the actions which it is requisite for us to 
        perform, we find in ourselves some prompter called a desire; and the more 
        essential the action, the more powerful is the impulse to its performance, and 
        the more intense the gratification derived therefrom.’[3] This is obviously true 
        of 'creature needs' such as food, sleep, and the continuance of the race. He 
        argues that it is also true of our social lives, where analogous impulses exist 
        leading to love of praise and the sentiment of friendship. His argument for the 
        moral sense is derived by analogy from these provisions of nature.
      May we not then reasonably expect to find a like 
        instrumentality employed in impelling us to that line of conduct, in the due 
        observance of which consists what we call morality? All must admit that 
        we are guided to our bodily welfare by instincts; that from instincts also, 
        spring those domestic relationships by which other important objects are 
        compassed-and that similar agencies are in many cases used to secure our 
        indirect benefit, by regulating social behaviour. Seeing, therefore, that 
        whenever we can readily trace our actions to their origin, we find them produced 
        after this manner, it is, to say the least of it, highly probable that the same 
        mental mechanism is employed in all cases-that as the all-important requirements 
        of our being are fulfilled at the solicitations of desire, so also are the less 
        essential ones-that upright conduct in each being necessary to the happiness of 
        all, there exists in us an impulse towards such conduct; or, in other words, 
        that we possess a 'Moral Sense', the duty of which is to dictate rectitude in 
        our transactions with each other; which receives gratification from honest and 
        fair dealing; and which gives birth to the sentiment of justice.[4]
      The existence of an innate instinct or faculty of moral 
        sense had been claimed by Hutcheson and the Scottish faculty psychologists but 
        rejected by Gay, Hartley, Paley, James Mill, and Bentham, who argued that all

      157
      moral feelings were the result of experience, 
        association, and reasoning. The Utilitarian view held that moral judgements 
        should be derived from calculations based on the utility of actions in leading 
        to the greatest happiness for the greatest number and that they should be 
        enforced by the dispensation of rewards and punishments by those in authority. 
        Gall believed that there was an innate faculty which suited men for living in 
        society, which he called 'Moral Sense, Sentiment of Justice and Injustice' (and, 
        variously, 'Goodness', 'Benevolence', and 'Compassion').[1] Gall was cautious in 
        his argument about this faculty. He had discovered it by his usual method of 
        correlating a large cranial prominence with extreme benevolence in three 
        individuals with identical cranial prominences. He inferred that these were 
        manifestations of an exaggerated degree of activity of the 'organ of 
        benevolence'.[2] He felt that he had made an insufficient number of observations 
        to enable him to determine the 'fundamental original destination' of the organ 
        and so, as he expressed it, 'resorted to reasoning’[3] He concluded 'that 
        goodness or benevolence is only a gradation of the moral sense',[4] which had as 
        its primitive destination to 'dispose man to conduct himself in a manner 
        conformed to the maintenance of social order'.[5] He was not prepared to 
        acknowledge a separate, fundamental quality of conscience and viewed it as an 
        'affection of the moral sense or of benevolence'.[6] Spurzheim departed from 
        Gall's view and argued for separate faculties of 'Goodness' (Gall's 
        'Benevolence') and of 'Conscientiousness' or 'Justice'.[7] Combe credits 
        Spurzheim with the discovery of Conscientiousness,[8] but his own account is 
        much fuller. He identifies the phrenological faculty with the Moral Sense 
        doctrine of Cudworth, Hutcheson, Reid, Stewart, and Brown. Combe held that 
        phrenology could settle the issue by providing observations demonstrating 'That 
        a power or faculty exists, the object of which is to produce the sentiment of 
        justice or the feeling of duty and obligation, independently of selfishness, 
        hope of reward, fear of punishment, or any extrinsic motive'.[9] It is the 
        source of feelings of right and wrong.[10]
      There is no obvious direct textual link between the 
        details of any of these phrenological formulations and Spencer's. Rather, his 
        argument adopts the form of the phrenological position while the resulting 
        conception of the moral sense is put in the service of his own social theory. 
        Spencer makes the phrenologists' identification between natural needs,

      instincts, and faculties, and in illustrating his 
        argument mentions ten of the faculties which are characteristic of phrenology, 
        e.g. parental affection,[l] geometric sense (sense of number),[2] and mechanical 
        sense.[3] He reaches the conclusion that the Utilitarian psychology is 
        inadequate as an account of men's propensities and that the Utilitarian morality 
        can only fail in its attempts at calculation of right and wrong in terms of 
        expediency and by means of reasoning about the greatest good for the greatest 
        number. Instead, one should study the innate propensities of individuals and the 
        environmental conditions to which they answer in order to arrive at a true 
        science of 'Moral Physiology'.[4] The existence of the moral sense insures that 
        the social behaviour which the Utilitarians would legislate for the public good 
        will occur naturally if only the state does not interfere with its ill-conceived 
        artifices.
      Spencer's second reason why men will act for the good 
        of others without the need for state action involves his view of the organismic 
        relation between society and its members. Public interests and private ones are 
        essentially in unison, and men have only to realize this. Spencer believes that 
        they will if left alone to discover it.
      When, after observing the reactions entailed by 
        breaches of equity, the citizen contemplates the relation in which he stands to 
        the body politic-when he learns that it has a species of life, and conforms to 
        the same laws of growth, organization, and sensibility that a being does-when he 
        finds that one vitality circulates through it and him, and that whilst social 
        health, in a measure depends upon the fulfilment of some function in which he 
        takes part, his happiness depends upon the normal action of every organ in the 
        social body-when he duly understands this, he must see that his own welfare and 
        all men's welfare are inseparable. He must see that whatever

      4 Spencer, 1851, p. 58. The phrenological work which 
        corresponds most closely to Spencer's position is George Combe's Essay on the 
          Constitution of Man and Its Relations to External Objects (1827). I have 
        seen no evidence that Spencer read it, but over seventy thousand copies of the 
        work were sold by 1838 (Temkin, 1947, p. 309; Cf. pp. 310-12). Combe considers 
        the relations between faculties and environmental conditions more explicitly 
        than Gall had. His view lies somewhere between a radical separation of man from 
        nature and the consistent naturalistic approach to man which came in the wake of 
        the theory of evolution. Man's relation to natural laws was that he could choose 
        to act in harmony with them or not. The relevant analogy is his relations with 
        civil and moral laws, and the argument is conducted in terms of ‘infringement' 
        and 'obedience'. These bring rewards or punishments, and happiness or evil 
        befall man in the measure that he obeys or disobeys the laws for which he has 
        been fitted (Combe, 1827, pp. 6, 7, 39, 46). Combe recast phrenological 
        principles in the light of natural theology, and his book should be read with 
        Paley's earlier work and later Bridgewater Treatises of Chalmers and Kidd in 
        mind. Combe is said to have complained that Chalmers' On the Adaptation of 
          External Nature to the Moral and Intellectual Constitution of Man (1833) 
        adopted the principles of his Essay without referring to it (Temkin, 1947 
        p.312). However, it is more likely that they had a common debt to Paley and the 
        tradition of natural theology.

      produces a diseased state in one part of the community, 
        must inevitably inflict injury upon all other parts. He must see that his own 
        life can become what it should be, only as fast as society becomes what it 
        should be. In short, he must become impressed with the salutary truth, that no 
        one can be perfectly free till all are free; no one can be perfectly moral till 
        all are moral; no one can be perfectly happy till all are happy.[1]
      In spelling out the details of this remarkably 
        optimistic conception, Spencer presents the view of organs and functions which 
        he later argued was all that he retained from phrenology, and on which he based 
        his view of cerebral localization.
      A FUNCTION to each organ, and each organ to its own 
        function, is the law of all organization. To do its work well, an apparatus must 
        possess special fitness for that work; and this will amount to unfitness for any other work. The lungs cannot digest, the heart cannot respire, the 
        stomach cannot propel blood. Each muscle and each gland must have its own 
        particular nerve. There is not a fibre in the body but what has a channel to 
        bring it food, a channel to take its food away, an agency for causing it to 
        assimilate nutriment, an agency for stimulating it to perform its peculiar duty, 
        and a mechanism to take away effete matter; not one of which can be dispensed 
        with. Between creatures of the lowest type, and creatures of the highest, we 
        similarly find the essential difference to be, that in the one the vital actions 
        are carried on by a few simple agents, whilst in the other the vital actions are 
        severally decomposed into their component parts, and each of these parts has an 
        agent to itself.[2]
      Reasoning by analogy from this physiological principle, 
        Spencer argues an organismic view of economic and social relationships. He does 
        this by means of a view of life borrowed from Coleridge, and examples taken from 
        zoology. Life, says Coleridge, consists in the progressive realization of a  'tendency to individuation'.[3] Spencer gives examples in the animal kingdom 
        to support the thesis that 'By greater individuality of parts-by greater 
        distinctness in the nature and functions of these, are all creatures possessing 
        high vitality distinguished from inferior ones'.[4] Tissues are progressively 
        individuated into separate organs adapted to separate ends.[5] The nervous 
        system is a notable example, and as it becomes progressively individuated, other 
        systems (such as the muscular, respiratory, and circulatory systems) are 
        simultaneously forming separate parts with special functions.[6]
      Higher organisms have greater powers and are more 
        self-sufficient and more individual. In man the individuation is most complete, 
        and

      160
      it is best manifested in the progressive evolution of 
        his ability to recognize the moral law of equal freedom.[1] Yet this 
        individuation requires mutual dependence in society.[2]
      Just that kind of individuality will be acquired which 
        finds in the most highly-organized community the fittest sphere for its 
        manifestation-which finds in each social arrangement a condition answering to 
        some faculty in itself-which could not, in fact, expand at all, if otherwise 
        circumstanced. The ultimate man will be one whose private requirements coincide 
        with public ones. He will be that manner of man, who, in spontaneously 
        fulfilling his own nature, incidentally performs the functions of a social unit; 
        and yet is only enabled so to fulfil his own nature, by all others doing the 
        like.[3]
      The identity of personal and social interests leads 
        Spencer to view society in organismic terms.
      We commonly enough compare a nation to a living 
        organism. We speak of 'the body politic', of the functions of its several parts, 
        of its growth, and of its diseases, as though it were a creature. But we usually 
        employ these expressions as metaphors, little suspecting how close is the 
        analogy, and how far it will bear carrying out. So completely, however, is a 
        society organized upon the same system as an individual being, that we may 
        almost say there is something more than analogy between them.[4]
      The historical development of society from its lowest 
        to its highest stages again exemplifies the close analogy to animal 
        organization. 'In the one extreme there are but few functions, and many similar 
        agents to each function: in the other, there are many functions, and few similar 
        agents to each function.'[5] There is an ever-increasing division of labour as a 
        result of the increasing subdivision of functions and separation of their 
        agents.[6]
      There are two justifications for considering these 
        passages from Social Statics in such detail. The first is to demonstrate 
        the influence of phrenological thinking on this seminal work of Spencer's. The 
        faculty psychology which he uses in conducting his arguments and the belief that 
        different functions are served by different organs throughout nature came 
        naturally to a formerly ardent student of phrenological faculties and their 
        organs. The second justification lies in the relations of the above passages 
        with his subsequent biological and psychological views. For present purposes the 
        passages must be lifted from their context and their use in his social theory 
        ignored.[7] Their importance

      7 He remained loyal to the organism-society analogy, 
        repeated it in the Principles of Biology (1864, I, 160, 163 ff) 
        and defended it (1908, pp. 570-1). Cf. Albee, 1962, for an analysis of Spencer's 
        ethical theories in Social Statics and his later writings.
       
      161
      to his later thinking is pointed out in two notes to 
        the revised edition in which he comments on the arguments quoted above:
      Until now (1890) that [sic] I am 
        re-reading Social Statics for the purpose of making this abridgement, the 
        above paragraph had remained for these 40 years unremembered. It must have been 
        written in 1849; and it shows that at that date I had entered on the line of 
        thought which, pursued in after years, led to the general law of evolutional[1]
      In the generalizations contained in the two above 
        paragraphs, and in the recognition of their parallelism, may be seen the first 
        step towards the general doctrine of Evolution. Dating back as they do to i850, 
        they show that this first step was taken earlier than I supposed.[2]
      Spencer's general theory of evolution and the 
        biological, evolutionary basis of his psychology grew out of the arguments for 
        specialization of functions which he elaborated in the context of his 
        phrenological interests. He later freed his evolutionary psychology from 
        phrenology, and the belief in cerebral localization (which was all that he 
        retained from his earlier allegiance), was based on the general theory of 
        evolution. However, it should be noted that this new basis for a remnant of his 
        phrenological interests had itself grown out of the theory it replaced. In what 
        follows an attempt will be made to trace in detail the development of Spencer's 
        biological view of psychology, its evolutionary basis, and its associationist 
        form.
      The development of Spencer's views subsequent to the 
        writing of Social Statics involves three closely intertwined themes. The 
        first is the abandonment of the faculty of psychology of phrenology in favour of 
        associationism. The second is a change in the foundations of his organfunction 
        view.
      He added this to other analogies borrowed from 
        embryology and development to elaborate his general theory of evolution. The 
        novel features of his psychology arise from the union of the concepts of 
        association and evolution and lead to a conception of psychology as a biological 
        science of adaptation. Third, when he returns to the consideration of 
        phrenology, almost as an afterthought in his Principles of Psychology, he retains only two aspects of the theory which formerly held his 
        intellectual loyalty. Certain of the phrenological faculties are present in 
        shadow form as the names for complex emotions, but these are no longer 
        fundamental faculties. They are the synthetic products

      162
      of associated individual and racial experiences. The 
        theory of cerebral localization is retained as a corollary of the general theory 
        of evolution from homogeneity to heterogeneity and of the resulting 
        physiological division of labour.
      Spencer's Interest in Psychology: From 
        Faculties to the Association of Ideas
      Before the publication of Social Statics,  Spencer's writings were primarily concerned with engineering topics, education, 
        and government. Shortly after the appearance of his book, he met George Henry 
        Lewes (Spring, 1850). They walked home together discussing the 'development 
        question' (evolution), and Spencer defended the mechanism of inheritance of 
        functional adaptations against the view of the Vestiges of the Natural 
          History of Creation.[1]
      Their friendship and their many long walks together had 
        important results, including the renewal of Lewes' interest in science and his 
        liaison with George Eliot, to whom Spencer introduced Lewes.[2]
      'One result of my friendship with Lewes was that I read 
        some of his books.' A novel did not impress Spencer either way. 'A more 
        important result, however, was that I read his Biographical History of 
          Philosophy, then existing in its original four-volume form. . . . Up to that 
        time questions in philosophy had not attracted my attention.' He had ignored a 
        copy of Locke's Essay on his father's shelf and rejected Kant's  Critique of Pure Reason after reading a few pages in 1844.[3]
      It is also true that though, so far as I can remember, 
        I had read no books on either philosophy or psychology, I had gathered in 
        conversations or by references, some conceptions of the general questions at 
        issue. And it is no less true that I had myself, to some extent, speculated upon 
        psychological problems-chiefly in connexion with phrenology. . . . Still, I had 
        not, up to 1851, made the phenomena of mind a subject of deliberate study.[4]
      I doubt not that the reading of Lewes's book, while it 
        made me acquainted with the general course of philosophical thought, and with 
        the doctrines which throughout the ages have been the subjects of dispute, gave 
        me an increased interest in psychology, and an interest, not before manifest, in 
        philosophy at large; at the same time that it served, probably, to give more 
        coherence to my own thoughts, previously but loose. No more definite effect, 
        however, at that time resulted, because there had not occurred to me any thought 
        serving as a principle of organization.[5]

      163
      Just as the reading of Lyell's refutation of Lamarck 
        turned Spencer towards belief in inheritance of acquired 
        characteristics,[l] the reading of Lewes' positivist polemics seems to have 
        turned him towards metaphysics. He wrote to his father in September 1851, that 
        he was absorbed in the subject.[2] Between the autumn of 1851 and the beginning 
        of 1852, Spencer decided to write a book on psychology.[3] He wrote to his 
        father in March, 'I shall shortly begin to read up in preparation for my 
        "Introduction to Psychology".' This was envisaged as the preliminary to a larger 
        work and was to contain its general principles.[4] Within two weeks, he wrote 'I 
        am just beginning to read Mill's Logic. This is my first step towards preparing 
        for my "Introduction to Psychology" which I mean to begin vigorously by and 
        by.'[5] Spencer does not specify the other sources of his psychological 
        development. However, the reading of Mill's Logic[6] and his subsequent 
        writings give ample evidence of the direction his thinking took.
      A direct result of his reading of Mill was the 
        formulation of what he considered to be a unifying concept for his psychology. 
        In reflecting on Mill's objections to Whewell, he was led to the formulation of 
        'The Universal Postulate'.[7] This was Spencer's ultimate criterion of belief: 
        the thesis that 'in the last resort we must accept as true a proposition of 
        which the negation is inconceivable'.[8] First begun in October, 1852, and 
        published as an essay a year later, this conception was expanded into Part I of 
        his Principles of Psychology.[9] Although the connection between this 
        part of his work and the rest is very tenuous indeed, it seems to have had the 
        psychological effect of spurring him on.
      Thus it appears that the general interest in mental 
        phenomena..... which I..... inferred was increased by reading Lewes's  Biographical History of Philosophy in the autumn of 1851, quickly 
        under that stimulus, began to have results. It was there remarked, that some 
        original conception in relation to the subject was needed to give me the 
        requisite spur; and this requirement was, it seems, fulfilled much sooner than I 
        supposed.[10]

      9 The article engendered a prolonged controversy with 
        Mill which is not relevant here. However, from the viewpoint of strictly 
        psychological issues Mill was quite right to apologize for this part of 
        Spencer's Principles as 'the very essence of the a priori  philosophy' while giving the remainder of the work a qualified recommendation. 
        (Mill, 1867, p. 99.) Mill's opinions changed somewhat toward a more favourable 
        view of Spencer's psychology, though not toward the first part. (Spencer, 1908, 
        pp. 114-5. Cf. Packe, 1954, pp. 431-4; Mill, 1872, p. 557.)

      Mill's conception of psychology[l] was firmly opposed 
        to the possibility of deriving a science of character from direct observation of 
        complex behaviour.[2] Nor could it be deduced from physiology. The true 'Laws of 
        Mind' were to be found by introspective observation and experiments on actual 
        'mental successions' and were based on the principle of association.[3] 'The 
        subject, then, of Psychology is the uniformities of succession, the laws, 
        whether ultimate or derivative, according to which one mental state succeeds 
        another-is caused by, or at least is caused to follow, another.’[4]
      In the edition of Mill's Logic which Spencer 
        read, the major authorities cited are James Mill and (to a lesser extent) 
        Hartley, though Bain is given precedence in later editions, and Spencer himself 
        is mentioned.[5] The science of character which Mill proposed was to be called 
        Ethology.
      The laws of the formation of character are, in short, 
        derivative laws, resulting from the general laws of mind, and are to be obtained 
        by deducing them from those general laws by supposing any given set of 
        circumstances, and then considering what, according to the laws of mind, will be 
        the influence of those circumstances on the formation of character.[6]
      In other words, Ethology, the deductive science, is a 
        system of corollaries from Psychology, the experimental science.[7]
      Mill's approach was opposed to phrenology by 
        implication, and he was also explicitly opposed to it in his writings and 
        activities. He closes his discussion of the relations between psychology and 
        physiology by saying,
      The latest discoveries in cerebral physiology appear to 
        have proved that any such connection which may exist [between mental 
        peculiarities and any varieties cognisable by our senses in the structure of the 
        cerebral and nervous apparatus] is of a radically different character from that 
        contended for by Gall and his followers, and that whatever may hereafter be 
        found to be the true theory of the subject, phrenology at least is untenable.[8]
      When William Carpenter published an extensive review of 
        a phrenological work which was scrupulously fair but highly critical of 
        phrenology, Mill wrote to him
      I should have been truly vexed not to have heard 
        immediately of such a valuable contribution to science as your paper. I have 
        read it once with great care, but I must read it a second time before I can have 
        completely incorporated it with my system of thought. I have long thought that 
        you

      were the person who would set to rights the pretensions 
        of present and the possibilities of future phrenology; but I did not venture to 
        hope that I should see, so soon, anything approaching in completeness and 
        conclusiveness to this.[1]
      Finally, it has been mentioned that Mill is supposed to 
        have convinced Bain to write his critical examination of phrenology as a 
        possible science of character.[2]
      The most important concomitant of Spencer's reading of 
        Lewes and Mill is the change that occurred in his psychological views. Whether 
        or not Spencer's change in allegiance can be directly attributed to the reading 
        of Mill's work must remain, for the present, an open question.[3] What is clear 
        is that Spencer's renewed interest in psychology took a form radically different 
        from his earlier phrenological work. He turned from the faculty formulation of 
        phrenology to a belief in associationism. This change can be chronicled with the 
        aid of a remarkable document.
      There was another essay written in Spencer's 
        phrenological period. The same letter that mentions the article later rejected 
        by Combe refers to an essay on 'The Force of Expression', which was duly 
        rejected by Tait's Magazine. 'It was not without merit; for, ten years 
        after, it was, with improvements, published in the Westminster Review, under the title of "The Philosophy of Style".’[4] Spencer revised and developed 
        the original essay during the early autumn of 1852.[5] The result provides an 
        excellent picture of his views in transition.
      The aim of the essay was 'to explain the general cause 
        of force in expression'.[6] Its relevance to the development of his 
        psychological views results from the fact that he attempts an explanation in 
        terms of the effect of various stylistic constructions on the mind of the 
        reader. For present purposes the details of his arguments about style are 
        incidental, but the language in which he writes is quite revealing. The essay 
        has a single point, with positive and negative aspects. His positive view is 
        that economy and vividness of verbal expression and arrangement promote ease of 
        understanding; the converse is that there is a danger of fatiguing the reader 
        which must be avoided by suitable variation and balance of verbal constructions. 
        These aspects are illustrated by numerous examples. Were this all, the essay 
        would be most uninteresting to the historian of science.

        this claim in primary sources.
      3 Spencer's MSS in the British Museum should be 
        carefully examined with this question in mind. A brief inspection has not 
        provided any help on Spencer's debt to Mill. Spencer was not generous in 
        acknowledging his intellectual debts.

      However, there is a point at which the language of his 
        argument changes abruptly to the faculty psychology of phrenology. It may even 
        be possible to specify the last sentence that underwent revision, since the 
        following one contains the first mention of faculties, and the whole of the 
        remainder of the essay is expressed in terms of faculties and groups of 
        faculties, their exercise and exhaustion.[1] The negative expression of 
        Spencer's thesis is 'that the sensitiveness of the faculties must be 
        husbanded'.[2] The emotions he refers to are those of reverence, approbation, 
        beauty. The different effects of words is 'dependent on the different states of 
        our faculties'.[3]
      The language in which he makes the positive point is 
        that of the association psychology. Force of expression is achieved by means of 
        the greatest economy of mental 'energy', 'effort', 'power', or 'attention'. The 
        mental law governing the effects of forms of expression is that of association. 
        The mental contents to which he refers are images, ideas, and their respective 
        elements. The mental functions involved are attention, imagination, memory, and 
        concentration. Until near the end of the positive statement of his thesis the 
        language is uniformly associationist.[4]
      All Spencer's subsequent writings employ the language 
        and assumptions of associationist psychology.
      There is one further point to be made about this 
        remarkable snapshot of a mind in transition. It is not the case that the last 
        portion of 'The Philosophy of Style' was left untouched, for the closing 
        paragraph reveals another manifestation of the development of Spencer's 
        psychology: the first extension of his concept of evolution to superorganic 
        phenomena.[5] In order to appreciate the significance of the union of 
        association psychology and his theory of evolution it will be necessary to look 
        further into the development of his view of evolution. For the
      1 The point of transition occurs at Spencer, 1901, II, 
        360. The last sentence in associationist language refers to 'mental energy' and 
        'strain on the attention'. The next sentence contains the first mention of 
        'perceptive faculties'.
      2 Ibid., II, 364.
      3 Ibid. The subsequent development of Spencer's views 
        is reflected in the fact that, in commenting on this essay in his  Autobiography, he uses neither the language of association psychology nor 
        that of phrenological faculties. His review of the thesis of the article is 
        given in terms of nervous energy and the sensibility of nervous structures. 
        (Spencer, 1904, I, 405-6.)
      4 The MS of this essay which Spencer deposited in the 
        British Museum neither supports nor detracts from my reading. In particular, it 
        shows no break at the point where the language changes to that of faculty 
        psychology (MS., p. 113), and faculty language does not appear to have been 
        deleted or replaced in the earlier portions of the MS. Since the last sentence 
        contains reference to a view which he did not hold until 1851, one may conclude 
        that it was probably a recopy of the revised version.

      present one should note the union of the old 
        phrenological psychology with the new faith in associationism and an embryonic 
        form of his concept of evolution in the revision of this essay from his 
        phrenological period.
      The Development of Spencer's General Theory of 
        Evolution
      Spencer claimed that a belief in evolution had been 
        latent in him since boyhood. He held that the view was implicit in the habit 
        which his father had encouraged of seeking natural causes of phenomena. This 
        entailed a disbelief in miracles, and therefore a relinquishment of the creed of 
        special creation. This process was occurring during his early manhood. It was 
        rather far-fetched for Spencer to claim retrospectively that the inevitable 
        corollary of belief in the universality of natural causation was a belief in 
        evolution, since this corollary had escaped so many scientists and philosophers 
        for centuries.[1]
      The first explicit convictions on evolution came from 
        reading Lyell's Principles of Geology when he was twenty. The argument  against Lamarck in Lyell's work led Spencer to a partial acceptance of both 
        the transmutation of species and the mechanism of inheritance of acquired 
        characters.[2] His belief in evolution never wavered, though the particular way 
        he expressed and applied it underwent considerable development.
      It has already been noted that Spencer later saw the 
        remarks on progressive specialization of function in animals and in societies, 
        which appeared in Social Statics, as 'the earliest foreshadowing of the 
        general doctrine of Evolution'.[3] The examples used in that work were largely 
        drawn from T. Rymer Jones' A General Outline of the Animal Kingdom. What 
        he took from Jones was the idea of progression from simple creatures, where the 
        duties of all structures are performed by one tissue, to more complex organisms 
        where separate organs are adapted to separate end.[4] Spencer had drawn from 
        this the analogy of increasing subdivision of functions in the development of 
        society.[5] However, in both cases the concept of development used in this work 
        'involving as it did the idea of function along with the idea of 
        structure,...... was limited to organic phenomena'.[6]
      Spencer encountered two phrases in the next two years 
        which consolidated his concept of evolution and freed it from this limitation.

      The first of these came from 'a little book just 
        published by Milne-Edwards' which Spencer and Lewes took with them on one of 
        their excursions in 1851:' 'the physiological division of labour'. This succinct 
        expression had the effect of sharpening the views of development he put forth in Social Statics.[2]
      The second phrase was discovered in W. M. Carpenter's Principles of Physiology (1851), which Spencer was reviewing: von 
        Baer's formula that 'the development of every organism is a change from 
        homogeneity to heterogencity'.[3] Though von Baer limited the concept to the 
        development of individual organisms, it was felt by Spencer to provide a general 
        formulation which could be applied to evolution beyond the organic world. The 
        first extension of the general concept of evolution crept into the end of the 
        essay on 'The Philosophy of Style'. He says that a perfect composition will 
        'answer to the description of all highlyorganized products both of man and 
        nature. It will be, not a series of like parts simply placed in juxtaposition, 
        but one whole made up of unlike parts that are mutually dependent'. On the 
        adjoining page it is suggested that progress in style 'must produce increasing 
        heterogeneity in our modes of expression'.[4]
      1 Spencer, 1908, p. 542. Henri Milne-Edwards (1800-85) 
        was a noted French zoologist and a pupil of Cuvier. He worked mainly on 
        invertebrate comparative anatomy. See Nordenskiöld, 1928, p. 425. Spencer does 
        not mention the title of the work he read, but it was probably Outlines of 
          Anatomy and Physiology (1850) or possibly Introduction à la zoologie générale (1851). The work and the principle of the division of labour are 
        considered, along with Milne-Edwards' career, in Russell, 1916, pp. 195-200. 
        Milne-Edwards believed in a sort of descent theory but rejected any explanation 
        in terms of natural causes (Ibid., pp. 244-5).

      3 Spencer, 1904, II, 8-9. Karl Ernst von Baer 
        (1792-1876), a German zoologist, was the most distinguished and influential of 
        the early nineteenth-century embryologists. His work was the culmination of 
        previous embryology and 'the point of departure of all that was to follow'. It 
        was he who converted embryology from philosophic speculation to a laboratory 
        science. His embryological law of development of special heterogeneous 
        structures from general homogeneous ones played an important, if confusing, part 
        in the history of evolutionary theory, and Carpenter's exposition of his work 
        was at the centre of the issue. Both Darwin and Spencer twisted von Baer's work 
        for their own evolutionary purposes. In fact, he was opposed to organic 
        evolution 'root and branch' and devoted his last years to an attempt at 
        destroying Darwin's work by removing the embryological supports which Darwin 
        considered crucial. Darwin's use of von Baer's work to support recapitulation 
        was diametrically opposed to the latter's conclusions. This story is 
        exhaustively told in two excellent essays in Glass, et al., 1959; 
        Oppenheimer, Jane. An Embryological Enigma in the Origin of Species (pp. 
        292-322), from which the above evaluation is taken, and Lovejoy, Arthur O., 
        'Recent Criticism of the Darwinian Theory of Recapitulation: Its Grounds and Its 
        Initiator (pp. 438-58). Lovejoy notes the similarity of von Baer's formulation 
        in embryology to Spencer's doctrine of the evolution of the universe, but he is 
        unaware of the direct link. He remarks, however, that Spencer's use of the 
        formula was 'essentially different from and opposed to the ideas of his German 
        predecessor'. (Ibid., p. 447.) Cf. Nordenskiöld, 1928, pp. 363-6, etc.: Russell, 
        1916, Chapter IX, etc.

      He had explicitly declared for organic evolution 
        several months before (March, 1852) in an essay on 'The Development 
        Hypothesis',[1] where it was argued that evolution of species is a much less 
        implausible hypothesis than special creation, and the persistence of the latter 
        view was attributed to ignorance and prejudice. He does not claim that actual 
        changes of species can be demonstrated or the modifying influences identified, 
        but argues that analogies to such processes are all around us, for example, 
        continuous series can be drawn between distinct geometrical shapes and the 
        development of a man from a single cell.[2]
      After writing 'The Development Hypothesis', 'the 
        evolutionary interpretation of things in general became habitual'.[3] It was 
        applied in various forms in essays written in 1853-4, and these applications led 
        naturally to his treatment of psychology where it became the central concept of 
        his Principles.
      The Writing of the Principles of Psychology  in Terms of Evolutionary Adaptation and Correspondence
      The simplest description of the Principles of 
        Psychology is that it united the association psychology with the theory of 
        evolution. However, it was not evolution itself but the view which Spencer took 
        of the development of mind which 'originated the book and gave its most 
        distinctive character'.[4] His expositor put the point more clearly than 
        Spencer: 'Two fundamental ideas rule the psychology of Mr Herbert Spencer: that 
        of the continuity of psychological phenomena; that of the intimate relation 
        between the being and its medium. These two points virtually contain his 
        doctrine.’[5] No psychologists except Gall and his followers had so emphatically 
        made the connection of mind with life, and the adaptation of the mental 
        functions to the environment, central to their views. Certainly no one in the 
        associationist tradition had gone so far in substituting a biological approach 
        for the traditional epistemological one. In fact, there is evidence that 
        Spencer's phrenological interests played an important part in his conception of 
        psychology as a biological science of adaptation.
      Adaptation was a major issue in Social Statics,  and Spencer's conception of it was derived directly from phrenology. In 
        attacking the general formulation of the Utilitarians, he criticized its failure 
        to take account
      1 Spencer, 1901, 1, 1-7.
      2 This essay and the Principles of Psychology  were recognized by Darwin as legitimate anticipations of his own view. (Darwin, 
        6th ed., 1928 p. 13.) He refers to 'your excellent essay on Development' in a 
        letter to Spencer. (Spencer, 1908, p. 98.) Cf. below pp. 188-92.

      of individual and racial differences. 'Adaptation of 
        constitution to conditions' was the cause of all physical and mental differences 
        among men.[1] The goal of his social theory was the attainment of 'congruity 
        between the faculties and their spheres of action'.[2] This leads to fulfilment, 
        gratification, and genuine happiness.[3] As long as the state does not interfere 
        and try to create an artificial identity of interests based on an erroneous 
        belief in a uniform human nature, 'this nonadaptation of an organism to its 
        conditions is ever being rectified; and modification of one or both, continues 
        until the adaptation is complete'.[4]
      These views were at two removes from Gall. The popular 
        phrenologists who had influenced Spencer, especially Spurzheim and Combe, had 
        abandoned Gall's belief in fixed mental endowment and held that the faculties 
        could be considerably altered by exercise. Spencer's meliorism went still 
        further to a belief in the inevitability of progress:
      Organs, faculties, powers, capacities, or whatever else 
        we call them, grow by use and diminish from disuse, [and] it is inferred that 
        they will continue to do so. And if this inference is unquestionable, then is 
        the one above deduced from it-that humanity must in the end become completely 
        adapted to its conditions-unquestionable also. Progress, therefore, is not an 
        accident, but a necessity.[5]
      This remarkable belief was the conclusion to his 
        argument that all maladaptation and imperfection would disappear if only the 
        excesses or defects of faculties could be allowed to correct themselves by 
        natural intercourse with the appropriate conditions of existence.[6]
      Spencer alluded to these views in reviewing the 
        development of his psychology.
      An early-impressed belief in the increase of faculty by 
        exercise in the individual, and the subsequently accepted idea of adaptation as 
        a universal principle of bodily life, now took, when contemplating the phenomena 
        of mind, an appropriately modified form.[7]
      This modification was formulated in 1853, as he was 
        accumulating memoranda and preparing to begin the book.[8] He had arrived at a 
        definition of life as 'the co-ordination of actions'. In applying this to 
        psychology it

      required to be supplemented by recognition of the 
        relations borne by such co-ordinated actions to connected actions in the 
        environment. There at once followed the idea that the growth of a correspondence 
        between inner and outer actions had to be traced up from the beginning; so as to 
        show the way in which Mind gradually evolves out of Life. This was, I think, the 
        thought which originated the book and gave its most distinctive character; but 
        evidently, the tendency to regard all things as evolved, which had been growing 
        more pronounced, gave another special interest to the undertaking.[1]
      Thus, when Spencer began writing the Principles  in August ' 1854, it was Part III, the 'General Synthesis, that he wrote 
        first.[2] 'Progressive adaptation became increasing adjustment of inner 
        subjective relations to outer objective relations-increasing correspondence 
        between the two.’[3] The adaptive view is unified with evolution from 
        homogeneity to heterogeneity.
      Previous association psychologists had been concerned 
        with the connections among mental phenomena. Natural scientists had concentrated 
        on the connections between external phenomena. The epistemological bias of the 
        Lockean tradition connected these two domains in terms of a knowing mind and its 
        objects. The aim of Spencer's psychology was neither the connections among 
        internal phenomena nor among external phenomena nor within knowledge itself.
      Hence, then, as in all cases we may consider the 
        external phenomena as simply in relation, and the internal phenomena also as 
        simply in relation; the broadest and most complete definition of life will be-The 
          continuous adjustment of internal relations to external relations.[4]
      .........not only does the definition, as thus 
        expressed, comprehend all those activities, bodily and mental, which constitute 
        our ordinary idea of life; but it also comprehends, both those processes of 
        growth by which the organism is brought into general fitness for those 
        activities, and those after-processes of adaptation by which it is specially 
        fitted to its special activities.[5]
      Mental phenomena are defined within this context as 
        'incidents of the correspondence between the organism and its environment'.[6]
      The correspondence between life and its circumstances 
        is treated in successive chapters as 'direct and homogeneous', as 'direct but 
        heterogeneous', as extending in space and time, as increasing in speciality, 
        generality, and complexity, as coordinated and as integrated.

      The degree of life varies with the degree of 
        correspondence. Bodily and mental life are but species of life in general. Mind 
        'emerges out of bodily life and becomes distinguished from it, in proportion as 
        these several traits of the correspondence become more marked'.[1]
      In adhering to the principle of continuity (perhaps 
        more completely and consistently than any previous writer except Leibniz), 
        Spencer was bound to apply his evolutionary view to the various categories of 
        physiological and psychological manifestations. He held that no truly valid 
        demarcations could exist among simple irritations, reflexes, their compounding 
        into instincts, the beginning of conscious life, and the highest manifestations 
        of intelligence-memory, reason, sentiment, and will. Memory, for example, is 
        dawning instinct, and instinct is organized memory.[2]
      Spencer's Evolutionary Associationism as an Advance 
        on Gall and on Traditional Sensationalism
      The foregoing story of Spencer's development provides 
        the necessary foundation for understanding both the implications of his 
        psychology for the associationist tradition, and its bearing on some of the 
        issues raised by Gall. Spencer's concept of mental evolution was at once an 
        integration of his view of adaptation with that of development from homogeneity 
        to heterogeneity, and an expression of his adherence to the association 
        psychology. It has been noted that the reading of Lyell had turned Spencer 
        toward a Lamarckian view of evolution. In 'The Development Hypothesis' the only 
        mention of a mechanism is the statement that animals and plants, when placed in 
        new conditions, undergo changes fitting them for their new environment. In 
        successive generations these changes continue 'until, ultimately, the new 
        conditions become the natural ones'.[3] In reviewing his application of this 
        view to psychological phenomena, Spencer says,
      The familiar doctrine of association here undergoes a 
        great extension; for it is held that not only in the individual do ideas become 
        connected when in experience the things producing them have repeatedly occurred 
        together, but that such results of repeated occurrences accumulate in 
        successions of individuals: the effects of associations are supposed to be 
        transmitted as modifications of the nervous system.[4]

      In the light of Spencer's development this extension 
        presents itself as the natural next step. Its simplicity is deceptive. In fact, 
        the application of evolution to psychology has consequences which are yet to be 
        fully exploited, but the present analysis must be confined to its effects on 
        psychological issues in the mid-nineteenth century. Spencer provided an 
        evolutionary theory which mediated between the conflicting claims of Gall's 
        psychology and the Lockean tradition of sensation-association.
      The choice for Locke in explaining the origin of 
        knowledge was between innate ideas and sensationalism. He opted equivocally for 
        the latter, and Condillac unequivocally made the choice for a tabula rasa view of mind. The attempt to build a psychology on this epistemological thesis 
        had been faced with serious limitations which centred around a vehement 
        objection to any endowment that suggested that mental phenomena were innate. 
        Evolutionary associationism was incompatible with a simple tabula rasa  view of mind.
      To rest with the unqualified assertion that, antecedent 
        to experience, the mind is a blank, is to ignore the all-essential 
        questions-whence comes the power of organizing experiences? whence arise the 
        different degrees of that power possessed by different races of organisms, and 
        different individuals of the same race? If, at birth, there exists nothing but a 
        passive receptivity of impressions, why should not a horse be as educable as a 
        man? Or, should it be said that language makes the difference, then why should 
        not the cat and dog, out of the same household experiences, arrive at equal 
        degrees and kinds of intelligence? Understood in its current form, the 
        experience-hypothesis implies that the presence of a definitely organized 
        nervous system is a circumstance of no moment-a fact not needing to be taken 
        into account! Yet it is the all-important fact-the fact . . . without which an 
        assimilation of experiences is utterly inexplicable.[1]
      These are the same objections that Gall made to 
        sensationalism: it could not explain individual and species differences, and it 
        ignored the fundamental importance of the biological endowment of varying brain 
        structures. In fact, Lewes credited Gall with settling the issue with which 
        Spencer is concerned.
      Gall may be said to have definitively settled the 
        dispute between the partisans of innate ideas and the partisans of 
        Sensationalism, by establishing the connate tendencies, both affective and 
        intellectual, which belong to the organic structure of man . . . all the 
        fundamental tendencies are connate, and can no more be created by precept and 
        education than they can be abolished by denunciation and punishment.[2]

      2 Lewes, 1857, p. 633. The edition of Lewes' book which 
        Spencer read did not include the chapter on Gall. It was added in the second 
        edition, which is quoted here. Cf. Young, 1966. p. 39 (fn. 77).

      Although Spencer echoed Gall's objections and his 
        emphasis on biological endowment and adaptation, he could accept neither the 
        view of nature nor the faculty psychology on which Gall's arguments were based. 
        Gall saw organic life in terms of the static chain of being. The cerebral 
        endowments of species were part of an eternally fixed order of nature, and he 
        believed that the organs were added in a stepwise fashion. The endowments of 
        individuals were also given at birth, and the role left for experience was very 
        meagre indeed. In his extreme reaction to the sensationalists in the name of 
        biological endowment, Gall had moved dangerously close to a belief in innate 
        ideas. In pursuing their epistemological interests the sensationalists had 
        clearly committed biological absurdities. Similarly, Gall had pursued his 
        biological and social interests faithfully and incidentally had talked 
        philosophical nonsense. Much of the reaction to his psychology was the result of 
        the supposed relation of faculties to innate ideas. In his zeal to show the 
        continuity of human behaviour with that of animals he had collapsed the 
        distinction between instincts and the most complex manifestations of human 
        intelligence. Thus, the laws of various pure and applied sciences were supposed 
        to be innately given as instincts in animals with striking talents and in human 
        geniuses.[1] The charge against Gall that he adhered to belief in innate ideas 
        was therefore not without foundation.
      Others had noted the relations between biologically 
        endowed instincts and innate ideas. For example, Johannes Mueller says, 'The 
        expression of Cuvier with reference to instinct is very correct. He says, that 
        animals in their acts of instinct are impelled by an innate idea,- as it were, 
        by a dream'.[2] In sharing this view Mueller argued, 'That innate ideas may 
        exist, cannot in the slightest degree be denied: it is, indeed, a fact. All the 
        ideas of animals, which are induced by instinct, are innate and immediate; 
        something presented to the mind, a desire to attain which is at the same time 
        given. The new-born lamb and foal have such innate ideas, which lead them to 
        follow their mother and suck the teats'.[3] However, he was not prepared to 
        extend this equation to man. To the question, 'Is it not in some measure the 
        same with the intellectual ideas of man?’[4] he replied with an emphatic denial 
        and reverted to the arguments of the sensationalists. The general intellectual 
        ideas of man result solely from 'the mutual reaction of allied perceptions 
        amongst themselves'.[5] He believed in fixed endowment where

      animals were concerned, and in sensationalism in human 
        intelligence.
      In addressing himself to this extremely confused set of 
        explanations and assumptions, Spencer had first to answer the argument of 
        special creation in the name of evolution, and then to mediate the conflicting 
        claims of the sensationalists and those who employed the concept of instinct. 
        His first attack was on the special creation hypothesis on which Gall had based 
        his objections to the sensationalists. Gall had argued the innate endowment of a 
        pre-established harmony between a faculty and its proper objects in the 
        environment. Speaking of this adjustment of psychical cohesions to relations 
        among objects in the environment, Spencer says,
      Concerning their adjustment, there appear to be but two 
        possible hypotheses, of which all other hypotheses can be but variations. It may 
        on the one hand be asserted, that the strength of the tendency which each 
        particular state of consciousness has to follow any other, is fixed beforehand 
        by a Creator-that there is a pre-established harmony between the inner and outer 
        relations. On the other hand it may be asserted, that the strength of the 
        tendency which each particular state of consciousness has to follow any other, 
        depends upon the frequency with which the two have been connected in 
        experience-that the harmony between the inner and outer relations, arises from 
        the fact, that the outer relations produce the inner relations.[1]
      Spencer believed that there was no real evidence to 
        support the special creation hypothesis. Speaking, though not directly, to 
        Gall's view, he says,
      That the inner cohesions of psychical states are 
        pre-adjusted to the outer persistencies of the relations symbolized, is a 
        supposition which, if taken in its full meaning, involves absurdities so many 
        and great that none dare carry it beyond a limited range of cases.[2]
      On the other hand, the supposition that the inner 
        cohesions are adjusted to the outer persistencies by an accumulated experience 
        of those outer persistencies, is in harmony with all our positive knowledge of 
        mental phenomena.[3]
      The evidence commonly cited to illustrate the doctrine 
        of the association of ideas made the evidence for the 'experience hypothesis' 
        overwhelming.[4]
      However, he also took account of the fact that the 
        major barriers to the rejection of special creation were the phenomena of reflex 
        action,

      176
      instinct, and the 'forms of thought' in man. ‘But 
        should these phenomena be otherwise explicable, the hypothesis must be regarded 
        as altogether gratuitous.’[1] Since Spencer's answer is the same for all three 
        of these sets of phenomena-evolution and association-the present discussion will 
        centre on the one which was historically most troublesome.
      The concept of instinct had been the traditional enemy 
        of both evolution and associationism. It had been cited as conclusive evidence 
        of special creation and design.[2] Gall held this view. Indeed, animal instinct 
        was chosen as the topic of one of the eight Bridgewater Treatises in 
        which natural theologians defended design by showing God's handiwork throughout 
        creation.[3] Conversely, Darwin's Origin, published four years after 
        Spencer's Principles, contained a chapter devoted to an attempt to 
        explain how instincts could evolve by natural selection. He considered this 
        issue one of the most formidable objections to his theory.[4] The antagonism 
        between the association psychology and explanations in terms of instincts goes 
        back to the inception of the school. The founding of the psychology of 
        association occurred in the Rev. John Gay's assertion of the possibility of 
        deducing the moral sense and all our passions from the pleasure-pain principle 
        and association.[5] Gay's dissertation was written in explicit opposition to 
        Hutcheson's claim that moral sentiments and disinterested affections are 
        innately given to the mind as instincts.[6] Gay's answer to Hutcheson was:
      Our approbation of Morality, and all Affections 
        whatsoever, are finally resolvable into Reason pointing out private 
          Happiness, and are conversant only about things apprehended to be means 
        tending to this end; and that whenever this end is not perceived, they are to be 
        accounted for from the Association of Ideas, and may properly 
        enough be call'd Habits.[7]
      Although Hutcheson's view may not in itself have been 
        'a-kin to the Doctrine of Innate Ideas, yet I think it relishes too much 
        of that of Occult Qualities'. [8] Gay goes on to argue that 'as some Men 
        have imagin'd Innate Ideas, because forgetting how they came by them; so 
        others have set up almost as many distinct Instincts as there are  acquired Principles of acting'.[9] The psychological aspect of Hartley's 
        associationism is an elaboration of this opposition to explanation in terms of 
        instinct.[10]

      177
      Five years later (1754) Condillac argued from his 
        extreme sensationalism to the position that instincts were acquired habits which 
        an individual derived from sensations and had ceased to reflect about. This 
        explanation left no way of accounting for the identity of instincts within 
        species and their marked differences between species. It is not surprising 
        therefore to find that the judgement made on eighteenth century associationism 
        was that, 'All attempts to explain instinct by this principle have hitherto been 
        unavailing'.[l] The aim had been to explain them away.
      After attention was explicitly turned to the 
        comparative study of instincts within evolutionary psychology, Romanes judged 
        the major nineteenth-century associationists prior to Spencer as follows: 'Mill, 
        from ignoring the broad facts of heredity in the region of psychology, may be 
        said to deserve no hearing on the subject of instinct; and the same, though in a 
        lesser degree, is to be remarked of Bain.’[2] It is with Spencer that Romanes 
        begins the serious debate on instinct and opposes Spencer's view in favour of 
        Darwin's.[3] J. S. Mill had granted the existence of instincts and admitted that 
        the association psychology could not explain them.
      No mode has been suggested, even by way of hypothesis, 
        in which these [human and animal instincts] can receive any satisfactory, or 
        even plausible, explanation from psychological causes alone; and there is great 
        reason to think that they have as positive, and even as direct and immediate, a 
        connexion with physical conditions of the brain and nerves as any of our mere 
        sensations have.[4]
      Nevertheless, both he and Bain persisted in the belief 
        that moral feelings or the moral sense were acquired by each individual during 
        his lifetime. Darwin was hesitant about quarrelling with Mill but claimed that 
        'it can hardly be disputed that the social feelings are instinctive or innate in 
        the lower animals; and why should they not be so in man? . . . The ignoring of 
        all transmitted mental qualities will, as it seems to me, be hereafter judged as 
        a most serious blemish in the works of Mr Mill'.[5] Of Bain's view, he said, 'On 
        the general theory of evolution this is at least extremely improbable'.[6] 
        Spencer wrote to Mill that the evolutionary theory could account for an innate 
        moral sense.
      I believe that the experiences of utility organized and 
        consolidated through all past generations of the human race, have been producing 
        corresponding nervous modifications, which, by continued transmission and 
        accumulation,

      178
      have become in us certain faculties of moral 
        intuition-certain emotions responding to right and wrong conduct, which have no 
        apparent basis in the individual experience of utility.[1]
      The innate moral sense that Spencer had argued in  Social Statics was thus retained, but its basis was changed from endowment 
        in the form of a phrenological faculty to endowment in the form of accumulated 
        species experience.
      Where instinctual phenomena had effectively opposed the 
        separate positions of evolution and associationism, Spencer believed that they 
        could be explained by the unified view of evolutionary associationism. 'The 
        doctrine that the connections among our ideas are determined by experience, 
        must, in consistency, be extended not only to all the connections established by 
        the accumulated experiences of every individual but to all those established by 
        the accumulated experiences of every race.’[2] Given this general principle, all 
        the phenomena of life and mind can be explained in terms of the experience 
        hypothesis.[3] The application of this view to reflex and instinct disposes of 
        their opposition to associationism and the basis of this objection in the belief 
        in preestablished harmony.
      Though it is manifest that reflex and instinctive 
        sequences are not determined by the experiences of the individual  organism manifesting them; yet there still remains the hypothesis that they are 
        determined by the experiences of the race of organisms forming its 
        ancestry, which by infinite repetition in countless successive generations have 
        established these sequences as organic relations: and all the facts that are 
        accessible to us, go to support this hypothesis. Hereditary transmission, 
        displayed alike in all the plants we cultivate, in all the animals we breed, and 
        in the human race, applies not only to physical but to psychical 
        peculiarities.[4]
      By replacing the tabula rasa of the individual 
        with that of the race, Spencer was able to retain the basic position of 
        sensationalism while recognizing the inherited biological endowments in the 
        nervous system, and avoiding the risk of the rationalist belief in innate ideas. 
        The term 'innate' thereby lost its Cartesian terrors for the empiricist. Baldwin 
        puts the position succinctly by saying that he replaced 'Condillac's individual 
        human statue by a racial animal colossus, so to speak'.,[5] And, most important 
        for the present purposes, he gave the statue an
      1 Quoted in Bain, 1875, p. 722. Bain has provided a 
        very useful history of pre-evolutionary views on the moral faculty (1875, pp.

      evolving nervous system and thus avoided the other 
        rationalist fallacy of referring mental endowments solely to an immaterial mind.
      The reduction of all distinction between instinct and 
        the highest intellectual operation of the human mind which Gall felt was 
        required by his biological, anti-sensationalist view could be abandoned when it 
        became appreciated that the higher operations could evolve out of simple 
        reflexes and instincts, and that the primitive could co-exist with the more 
        advanced. Finally, the analytic principle and the genetic method which had been 
        the central thesis of the Lockean tradition (and its main contributions to 
        philosophy, psychology, and science) were retained and extended to a much wider 
        domain. Gall had found it necessary to fall short of a rigorous application of 
        the principle of continuity in order to give some reality to the faculties which 
        he felt to be the important variables in behaviour. Spencer made it possible to 
        retain a consistent application of continuity in the evolution of relatively 
        stable functions, while still granting their reality and efficacy for the 
        individual. Psychology was freed from the static adaptations of Gall's innate 
        faculties and the more general application of the pre-established harmony of the 
        special creation view. All of this was achieved by the comparatively simple 
        expedients of (1) placing the principle of continuity on a temporal basis for 
        the race; (2) extending the principles of the psychology of sensation and 
        association to include the dynamic interactions between an organism and its 
        environment; (3) stabilizing the results of these interactions in the nervous 
        systems of various species.
      Having provided himself with a uniform explanatory 
        principle, Spencer applied it to the evolution of mind from the contraction of a 
        sensitive polyp on irritation, and through the development of specialized 
        tissues-nerves for irritation and muscles for movement. The simple reflex is the 
        transitional point of nervous differentiation from the merely physical.[1] 
        Instincts are complex reflexes whereby a combination of impressions produces a 
        combination of contractions.[2] This increasing complexity involves such 
        phenomena as the recognition of prey or a predator, and the activities necessary 
        for capture or flight.[3] Still more complex correspondences lose their 
        indivisibility, become dissociated, and occur independently. The impression is 
        freed from both the immediate presence of the stimulus and the requirement for 
        immediate response.[4] This is the dawn of conscious memory. Reason is but one
      1 Spencer, 1855, pp. 533-8.
      2 Ibid., p. 542.
      3 Ibid., pp. 539-53.
      4 Ibid., pp. 555-63.
       
      180
      more step in the developing complexity of relations of 
        inner to outer-a further part of the insensible evolution. Both memory and 
        reasoned action tend to lapse into automatism.[1] As a last step, the 'forms of 
        thought', the last bastion of the rationalist position, are absorbed into the 
        sensationalist explanation. Space, time, causation, and so on, became 
        explicable.
      Finally, on rising up to human faculties, regarded as 
        organized results of this intercourse between the organism and the environment, 
        there was reached the conclusion that the so-called forms of thought are the 
        outcome of the process of perpetually adjusting inner relations to outer 
        relations; fixed relations in the environment producing fixed relations in the 
        mind. And so came a reconciliation of the a priori view with the 
        experiential view.[2]
      In addressing himself to the issue which had exercised 
        epistemologists at least since Plato, and which is one of the thorniest 
        questions of modern philosophy, Spencer implicitly asserts that such questions 
        must henceforth be seen as psychological and therefore as biological. The answer 
        which Spencer gave to the old question of the origin of ideas came not from 
        metaphysics but from heredity. At this point the development of psychology from 
        a branch of speculative metaphysics to a biological science is, in principle, 
        complete. However, it will become abundantly clear that what was conceived in 
        principle in 1855 has yet to be thoroughly applied in practice.
      Implications of Evolutionary Associationism for 
        Traditional Issues
      Associationists had always been opposed to faculty 
        psychology, but before their view had been joined to evolution they could offer 
        no convincing alternative. For example, Bain merely asserted that the principle 
        of association of ideas was adequate to supersede and explain all the phenomena 
        formerly attributed to the faculties of the Lockean tradition.[3] In dealing 
        with the phrenological faculties in On the Study of Character, he 
        argued that these were not fundamental, that they could be reduced to one of the 
        classes of his own theory, and that these, in turn, could be explained by the 
        laws of association and the pleasure-pain principle. But he had no convincing 
        explanation for the enduring features of mental experience and behaviour. 
        Spencer could provide an explanation of the development of the various modes of 
        manifestation of intelligence and grant their relative stability in the species 
        without making them distinct mental agents. His evolutionary associationism 
        freed him from the usual procedure of starting at birth with a
      1 Spencer, 1855, pp. 568-9.

      3 Bain, 1868, p. 693.
       
      181
      tabula rasa and explaining the development of 
        the complex phenomena of instinct, emotion, and intellectual functions on the 
        basis of individual experience alone.
      Spencer grants that there are valid differences among 
        the various 'modes of intelligence known as Instinct, Memory, Reason, Feeling, 
        Will, and the rest'.[l] However, in their true nature they are only phases of 
        correspondence, and their genesis is by insensible degrees. He considers the 
        faculties and emotions neither fundamental nor distinct nor part of a fixed 
        endowment. 'Intelligence has neither distinct grades, nor is constituted of 
        faculties that are truly independent; but that its highest phenomena are the 
        effects of a complication that has arisen by insensible steps out of the 
        simplest elements.' There are no valid demarcations. Classifications of 
        faculties
      can be but superficially true. Instinct, Reason, 
        Perception, Conception, Memory, Imagination, Feeling, Will, etc., etc., can be 
        nothing more than either conventional groupings of the correspondences; or 
        subordinate divisions among the various operations which are instrumental in 
        effecting the correspondences. However widely contrasted they may seem, these 
        various forms of intelligence cannot be anything else than either particular 
        modes in which the adjustment of inner to outer relations is achieved; or 
        particular parts of the process of adjustments.[2]
      The phrenological faculties retained none of their 
        independent status as mental agents in Spencer's psychology. After his 
        conversion to associationism they were retained only as the names of the 
        emotions.[3] The emotions are not included in the analytic chapters of the  Principles of Psychology. Indeed, the whole analytic half of the work 
        is singularly uninteresting for present purposes. The 'General Analysis' 
        consists of an expanded version of his defence of realism and his criterion of 
        belief-the Universal Postulate. The 'Special Analysis' is old-style 
        epistemological psychology-analysis of the forms of reasoning, perceptions of 
        external objects, space, time, motion, and so on, and various mental relations. 
        The aim of this part of his work is the traditional analysis of complex mental 
        phenomena into their elements, explaining their cohesions by means of the laws 
        of association.[4] The interest which the work holds for the modern reader is 
        confined to those parts in which the old-style associationism is recast in an 
        evolutionary framework.

      The treatment which Spencer gives to the emotions in 
        the Principles of Psychology is but one more application of his 
        evolutionary associationism to the synthesis of complex mental phenomena.
      The progress from the initial forms of feeling to those 
        complicated forms of it seen in human beings, equally harmonizes with the 
        general principles of evolution that have been laid down. Arising, as it does, 
        when the automatic actions, from increasing complexity and decreasing frequency, 
        become hesitating; and consisting, as it then does, of nothing more than the 
        group of sensations received and the nascent motor changes aroused by them; 
        feeling, step by step developes [sic] into larger and more varied 
        aggregations of psychical states-sometimes purely impressional, sometimes 
        nascently impressional or ideal; sometimes purely motor, sometimes nascently 
        motor; but very frequently including in one combination, immediate impressions 
        and the ideas of other impressions, with immediate actions and the ideas of 
        other actions. And this formation of larger and more varied aggregations of 
        psychical states, necessarily results from the accumulating cohesions of 
        psychical states that are connected in experience. Just as we saw that the 
        advance from the simplest to the most complex forms of cognition, was explicable 
        on the principle that the outer relations produce the inner relations; so, we 
        shall see that this same principle supplies an explanation of the advance from 
        the simplest to the most complex feelings.[1]
      Prior to Spencer-or, more generally, prior to the 
        theory of evolution -the associationists had been no more successful in 
        explaining emotions than they had been with instincts. This was admitted by J. 
        S. Mill in his review of 'Bain's Psychology': 'It is certain that the attempts 
        of the Association psychologists to resolve the emotions by association, have 
        been on the whole the least successful part of their efforts.’[2] This judgement 
        was repeated by their expositor, Ribot.[3] Bain's psychology -the culmination of 
        pure associationism-did not contain a general analysis of the emotions. Although 
        successive editions of Bain's work included results of the new evolutionary 
        studies of Spencer and Darwin, these are 'added on', and the new thinking did 
        not vitally affect his essentially pre-evolutionary view.[4] Evolutionary 
        associationism could acknowledge the stability of the emotions in a species, 
        which had been the strength and danger of Gall's faculty psychology, while 
        retaining their experiential origins-the strength and weakness of 
        associationism.
      That the experience-hypothesis, as ordinarily 
        understood, is inadequate to account for emotional phenomena, will be 
        sufficiently manifest. If possible, it is even more at fault in respect to the 
        emotions than in respect to the cognitions. The doctrine maintained by some 
        philosophers, that all the

      desires, all the sentiments, are generated by the 
        experiences of the individual, is so glaringly at variance with hosts of facts, 
        that I cannot but wonder how any one should ever have entertained it. Not to 
        dwell on the multiform passions displayed by the infant, before yet there has 
        been such an amount of experience as could by any possibility suffice for the 
        elaboration of them; I will simply point to the most powerful of all 
        passions-the amatory passion-as one which, when it first occurs, is absolutely 
        antecedent to all relative experience whatever.[l]
      Attempts at explanation of complex emotions as 
        developments wholly within the life of an individual are absurd. The alternative 
        to explanation of the origin of emotions within the life of the individual is 
        the view that their evolution takes place through countless generations.
      By the accumulation of small increments, arising from 
        the constant experiences of successive generations, the tendency of all the 
        component psychical states to make each other nascent, will become gradually 
        stronger. And when ultimately it becomes organic, it will constitute what we 
        call a sentiment, or propensity, or feeling, having this set of circumstances 
        for its object.[2]
      Spencer had little more than this to say about emotions 
        in the Principles of Psychology. Fortunately, he wrote a critical review 
        of Bain's The Emotions and the Will, in which he provides a very incisive 
        comment on the limitations of pre-evolutionary associationism, and spells out 
        the implications of the new context for future investigations. The remarkable 
        thing about the review is how clearly he saw the meaning of evolution for 
        associationism at a time (1860) when evolution was just attaining the centre of 
        intellectual discourse. The first systematic observations in evolutionary 
        psychology were still over twenty years away. One should recall, though, that by 
        1860 he had been writing on evolutionary psychology for almost ten years.
      Spencer clearly understood one of Bain's two principal 
        contributions, as well as his major limitation.
      The facts brought to light by anatomists and 
        physiologists during the last fifty years, are at length being used towards the 
        interpretation of this highest class of biological phenomena; and already there 
        is promise of a great advance. The work of Mr. Alexander Bain..... may be 
        regarded as especially characteristic of the transition.[3]
      On the other hand, Spencer betrays no hint that he 
        grasped either Bain's theory of activity or its significance. Given his reading 
        habits

      184
      it is even doubtful if he read the relevant parts of 
        Bain's book.[1] His criticism of Bain's concept of volition has as its text a 
        single sentence from the first paragraph of the book.[2] Consequently, Spencer 
        is silent on the aspect of Bain's work which later evolutionary and functional 
        psychologists would use to complement the tendency toward passivity in Spencer's 
        concept of adaptation.
      Spencer also recognizes Bain's place in the development 
        of psychology from a speculative and deductive branch of metaphysics to that of 
        a biological science.
      Until recently, mental science has been pursued much as 
        physical science was pursued by the ancients; not by drawing conclusions from 
        observations and experiments, but by drawing them from arbitrary a priori  assumptions. This course, long since abandoned in the one case with immense 
        advantage, is gradually being abandoned in the other; and the treatment of 
        Psychology as a division of natural history, shows that the abandonment will 
        soon be complete.[3]
      Bain's work aimed to provide a 'natural history of the 
        mind'.[4] As such 'we believe it to be the best yet produced'.[5] 'Of its kind 
        it is the most scientific in conception, the most catholic in spirit, and the 
        most complete in execution.'[6] However, the natural history method as used by 
        Bain is not enough, and his work is therefore essentially transitional.[7]
      Bain's classification of the emotions was derived from 
        the expressions and feelings displayed in the adult.
      Thus, then, Mr. Bain's grouping is throughout 
        determined by the most manifest attributes-those objectively displayed in the 
        natural languages of the emotions, and in the social phenomena that result from 
        them, and those subjectively displayed in the aspects the emotions assume in an 
        analytical consciousness. And the question is-Can they be correctly grouped 
        after this method? We think not.[8]
      We think that Mr. Bain, in confining himself to an 
        account of the emotions as they exist in the adult civilized man, has neglected 
        those classes of facts out of which the science of the matter must chiefly be 
        built.[9]
      The complete natural-history-method involves ultimate 
        analysis, aided by development; and Mr. Bain, in not basing his classification 
        of the emotions on characters reached through these aids, has fallen short of 
        the conception with which he set out.[10]
      In brief, he has written a Descriptive Psychology, 
        which does not appeal to Comparative Psychology and Analytical Psychology for 
        its leading ideas.

      And in doing this, he has omitted much that should be 
        included in a natural history of the mind; while to that part of the subject 
        with which he has dealt, he has given a necessarily imperfect organization.[1]
      Spencer argues that comparative and developmental 
        psychology can supply the studies which Bain's work lacked. Four types of 
        investigation must precede and guide the traditional associationist analysis:
      1. 'Study the evolution of the emotions up through the 
        various grades of the animal kingdom . . . and how they are severally related to 
        the conditions of life.'
      2. Compare the emotions in lower and higher human 
        races.
      3. 'In the third place, we may observe the order in 
        which the emotions unfold during the progress from infancy to maturity.'
      4. Comparing the results 'displayed in the ascending 
        grades of the animal kingdom, in the advance of the civilized races, and in 
        individual history', we should seek harmony and general truths.[2]
      It is only after the above studies have been 
        made that one can attempt the analysis of complex adult human emotions into 
        their elements. Such analysis must be guided by comparative and developmental 
        information.[3]
      Spencer's approach to the analysis of the emotions 
        provides a very significant advance on the previous work of the associationist 
        tradition. By insisting that comparative and developmental studies must precede 
        and guide the application of the genetic method to the emotions as experienced 
        subjectively, he challenged a fundamental assumption of those psychologists who 
        believed that philosophical and introspective analyses were adequate methods. 
        The assumption was that the actual development of emotions, indeed of all 
        psychological phenomena, conforms to the categories and sequences according to 
        which we can interpret them introspectively. Spencer insisted that biological 
        studies must precede introspective analysis and thus raised the issue of whether 
        the analytic classification conforms to a natural classification, whether 
        psychologists' accounts of the synthesis of complex psychological phenomena are 
        accurate reflections of their actual synthesis in evolution and in individual 
        experience. The study of psychological phenomena is thereby transferred from 
        plausible verbal analysis of the complex to the simple (like James Mill's), or 
        verbal syntheses of everyday psychological life from simple elements (like 
        Condillac's). Speculative and verbal analyses are replaced by biological 
        observations and (later)

      186
      experiment. Once again, Spencer's arguments echo Gall's 
        objections to the sensationalists while his answers depart from Gall's innately 
        given static faculties and supply an alternative within the associationist 
        tradition by uniting it with evolution.
      It must be recognized, that in spite of his biological 
        viewpoint, Spencer did not transcend the classificatory scheme of the 
        association psychology. He offered a more plausible explanation of the genesis 
        of psychological functions than his predecessors, but he retained their 
        classification of those functions. He showed that explanation in terms of 
        faculties was fallacious, and this was an advance on Gall. However, he failed to 
        derive, or even advocate, the set of biological functions which Gall had sought, 
        for which the evolutionary theory provided a sound basis. Evolutionary 
        associationism thus failed to provide an integrated, biological psychology, and 
        its objective descendant, behaviourism, has done no better. Instinct, Reason, 
        Perception, Conception, Memory, Imagination, and so on, remain the topics or 
        chapter headings in contemporary psychological works. One approach -modern 
        ethology-offers hope of finally transcending the categories of medieval 
        psychology and providing a nomenclature that fulfils the promise of evolutionary 
        psychology by means of naturalistic observation followed by controlled 
        experiments.
      The Mechanism of Evolution
      Spencer's criticism of accounts by traditional 
        associationists closes with his explanation of how new emotions are evolved. 
        This discussion raises an issue which has been deliberately ignored throughout 
        the present study: Spencer's belief in the inheritance of acquired 
        characteristics. His theory will first be given and then considered in its 
        historical context.
      The mechanism which he adopted was avowedly 
        'Lamarckian'. Acquired habits are passed from generation to generation until 
        they become fixed in the nervous system. 'Every one of the countless connections 
        among the fibres of the cerebral masses, answers to some permanent connection of 
        phenomena in the experiences of the race.'[l] What the individual feels as 
        homogeneous emotions undecomposable into specific experiences, are in fact 'the 
        organized results of certain daily-repeated combinations of mental states' and 
        consist of 'aggregated and consolidated groups of those simpler feelings which 
        habitually occur together in experiences
      1 Spencer, 1855, p. 581.
      2 Spencer, 1901, I, 254; Cf. 256.
       
      187
      Spencer spells out this view in some detail, and since 
        his exposition considers the question which most troubles the modern reader, it 
        will be given in full.
      When, in the circumstances of any race, some one kind 
        of action or set of actions, sensation or set of sensations, is usually 
        followed, or accompanied, by various other sets of actions or sensations, and so 
        entails a large mass of pleasurable or painful states of consciousness; these, 
        by frequent repetition, become so connected together that the initial action or 
        sensation brings the ideas of all the rest crowding into consciousness: 
        producing, in some degree, the pleasures or pains that have before been felt in 
        reality. And when this relation, besides being frequently repeated in the 
        individual, occurs in successive generations, all the many nervous actions 
        involved tend to grow organically connected. They become incipiently reflex; 
        and, on the occurrence of the appropriate stimulus, the whole nervous apparatus 
        which in past generations was brought into activity by this stimulus, becomes nascently excited. Even while yet there have been no individual experiences, a 
        vague feeling of pleasure or pain is produced; constituting what we may call the 
        body of the emotion. And when the experiences of past generations come to be 
        repeated in the individual, the emotion gains both strength and definiteness; 
        and is accompanied by the appropriate specific ideas.[1]
      In the next paragraph he considers and rejects the 
        mechanism of natural selection. The example he considers is that of birds, on a 
        formerly undiscovered island, whose behaviour evolves from an initial lack of 
        fear of man to innate dread.
      Now unless this change be ascribed to the killing-off 
        of the less fearful, and the preservation and multiplication of the more 
        fearful, which, considering the comparatively small number killed by man, is an 
        inadequate cause; it must be ascribed to accumulated experiences; and each 
        experience must be held to have a share in producing it. We must conclude that 
        in each bird which escapes with injuries inflicted by man, or is alarmed by the 
        outcries of other members of the flock (gregarious creatures of any intelligence 
        being necessarily more or less sympathetic), there is established an association 
        of ideas between the human aspect and the pains, direct and indirect, suffered 
        from human agency.[2]
      He goes on to infer that the emotion is a memory of 
        these pains. In the course of generations, the nervous system is modified by 
        these experiences, and thus young birds fly away at the sight of man as a result 
        of a partial excitement of the nerves previously excited in their ancestors and 
        the consequent painful consciousness. 'The vague painful consciousness thus 
        arising, constitutes emotion proper.’[3]

      2 Ibid., 1, 255.
      3 Ibid., I, 256.
       
      188
      Later, Spencer slightly modified his belief that 
        natural selection was an 'inadequate cause'. He added the following note to the 
        1870 edition of the Principles of Psychology:
      Had Mr. Darwin's Origin of Species been 
        published before I wrote this paragraph, I should, no doubt, have so qualified 
        my words as to recognize selection,' or artificial, as a factor. At the time the 
        first edition was written the only factor I recognized was the inheritance of 
        functionally-produced changes; but Mr. Darwin's work made it clear to me that 
        there is another factor of importance in mental evolution as in bodily 
        evolution. While holding that throughout all higher stages of mental development 
        the supreme factor has been the effect of habit, I believe that in producing the 
        lowest instincts natural selection has been the chief, if not the sole, 
        factor.[l]
      Spencer defended this position in the face of growing 
        objections in the last quarter of the century, and reiterated it as late as 
        1899.[2]
      Flugel points out that Spencer's belief in the 
        inheritance of acquired characteristics 'contributed not a little to the general 
        decline of interest in his work'.[3] It should be remembered, however, that this 
        judgement did not begin to become operative until well after the period under 
        consideration here (until after Weismann distinguished somatic changes from the 
        stability of the transmitted 'germ-plasm' in 1885), and that Darwin himself laid 
        increasing emphasis on use-inheritance in his writings after 1859. In fact it 
        was Spencer who pointed this out in a careful analysis of Darwin's later 
        writings. 'The Factors of Organic Evolution' (1886).[4] Darwin had no reason to 
        quarrel with Spencer's view and altered the brief but crucial passage on man in 
        the Origin to include a highly complimentary reference to Spencer. The 
        first edition says, 'In the distant future I see open fields for far more 
        important researches. Psychology will be based on a new foundation, that
      1 Spencer, 1908, p. 565.
      2 Ibid., p. 547. See also various articles by Spencer 
        on the formula of evolution, mental evolution, inheritance of acquired 
        characteristics, Weismannism, heredity, and so on, written between 1871 and 1898 
        and listed in his bibliography. (Spencer, 1908, pp. 581-6.) Most of these are 
        reprinted in the second edition of Principles of Biology (1898-9),  Various Fragments (1900), and Facts and Comments (1902). For 
        an excellent discussion of the contemporary debate, see Romanes (1892, pp. 
        253-7; 1916, pp. 64-8, and passim). Spencer makes a greater concession to 
        natural selection in his Autobiography: 'The Origin of Species  made it clear to me that I was wrong; and that the larger part of the facts 
        cannot be due to any such cause' [as 'the inheritance of functionally-produced 
        modifications']. (Spencer, I 904, II, 50.)

      4 Spencer, 1901, I, 389-466. Cf. Romanes, 1916, pp. 
        2-12. Spencer reiterates his Lamarckian psychological views in the Preface to a 
        pamphlet version of this essay (1887, pp. iii-iv) which is omitted from the  Essays. (See Young, 1967). It was on the basis of their belief in the 
        inheritance of acquired characteristics (even though by means of nervous 
        arrangements) that both Darwin and Spencer were accused of reverting to belief 
        in 'innate ideas'. (Höffding, 1909, p. 451 ; Meynert, enlisting support from 
        Weismann, 1885, pp. viii, 274).

      of the necessary acquirement of each mental power and 
        capacity by gradation. Light will be thrown on the origin of man and his 
        history.'[l] Darwin had not read Spencer's Principles of Psychology when 
        he wrote this. In later editions of the Origin (6th edition, 1872), 
        Darwin altered these sentences to read, 'Psychology will be securely based on 
        the foundation already well laid by Mr. Herbert Spencer'.[2] Darwin's private 
        opinion of Spencer underwent very wide fluctuations, from extreme admiration of 
        him as perhaps England's greatest philosopher, and feelings of inferiority, to 
        personal dislike and even contempt for his speculative bent.[3]
      One further judgement should be given to help obviate 
        the current reaction to Spencer's views on the mechanism of evolution. Speaking 
        of the period 1851-58, T. H. Huxley said,
      The only person known to me whose knowledge and 
        capacity compelled respect, and who was, at the same time, a thoroughgoing 
        evolutionist, was Mr. Herbert Spencer, whose acquaintance I made, I think, in 
        1852, and then entered into the bonds of a friendship which, I am happy to 
        think, has known no interruption. Many and prolonged were the battles we fought 
        on this topic. But even my friend's rare dialectic skill and copiousness of apt 
        illustration could not drive me from my agnostic position.[4]
      The point of this discussion of Lamarckianism is that 
        what is now seen as a totally erroneous view of the mechanism of evolution was 
        one of those immensely fruitful errors in the history of science which the 
        historian would be mistaken to criticize. Like phrenology, it must be judged in 
        the light of its heuristic value. There is little point in considering in detail 
        the work generated by the general theory of evolution throughout biology: the 
        whole basis of the science was transformed. This occurred despite the gropings, 
        hesitations, and partial recantations of its early exponents. The same may be 
        said for evolutionary psychology. The concept of psychology as a biological 
        science based on the evolutionary theory was completely reorienting the science 
        in the half-century following the first statements of Spencer and Darwin. When 
        the mechanism of evolution became more clearly understood, it could find its 
        rightful place within the general approach. Use-inheritance gave way to random 
        mutation and natural selection. But the evolutionary basis of concepts which had 
        defeated the associationists such as

      reflex, instinct, and emotion had been established in 
        the meantime, even though the precise mode of their transmission is still not at 
        all clearly understood. Although Spencer was wrong about the mechanism of 
        evolution, modern views support his main theme: the adaptations of living things 
        to their surroundings are evoked by problems posed by their environments.[1] 
        That they are evoked by natural selection of random genetic mutations was not 
        the main issue in converting psychology to a biological science of adaptation.
      Therefore, Spencer's erroneous mechanism for evolution 
        has been deliberately and properly ignored in discussing his work, because it is 
        irrelevant to the historical development of the concepts with which the present 
        discussion is concerned.
       
      The Influence of Spencer
      Two changes have been emphasized as extremely important 
        in the nineteenth-century development of psychology away from its position as a 
        branch of epistemology. The first is its conception as a biological science; the 
        second is its close relations with neurophysiology. It was argued above that 
        Gall played an important role in establishing both approaches at the beginning 
        of the nineteenth century. Spencer and Gall shared these two major premises 
        about psychology, and there is much evidence to suggest that Spencer arrived at 
        them during the period of his early phrenological allegiance. Spencer also 
        shared with Gall the stylistic and personal traits of pomposity, conceit, and 
        long-windedness, as well as the fate of being reviled and ridiculed by the 
        subsequent generations which were most indebted to him. Finally, they both 
        influenced others more through important general principles and approaches than 
        by specific empirical findings. In Gall's case the findings were erroneous and 
        in Spencer's nonexistent. Both advocated studies which they did not successfully 
        conduct themselves.
      Spencer's position in the last half of the nineteenth 
        century was that he shared with Darwin the establishment of psychology on a 
        biological, evolutionary foundation and with Bain the close alliance of 
        associationism with sensory-motor psychophysiology.
      Darwin pioneered studies in comparative and genetic 
        psychology in the chapter on 'Instinct' in the Origin (I859), Chapters 
        III and IV of the Descent of Man (1871), The Expression of the 
          Emotions in Man and Animals (1872), 'A Biographical Sketch of an 
        Infant' (1877), various

      shorter papers,[l] and the extensive materials on 
        instinct which he made available to Romanes and which appeared in Mental 
          Evolution in Animals (1883). Although an adequate account of Darwin's 
        psychological work remains to be written, there have been a number of studies 
        dealing with aspects of his overwhelming importance in the development of 
        psychology as a branch of evolutionary biology in the three separable areas of 
        comparative psychology, functional psychology, and the study of the nervous 
        system.[2]
      While Darwin was primarily responsible for the general 
        climate of evolutionary thinking and provided many detailed observations, he was 
        somewhat naïve in his approach to psychology, and could not provide the language 
        with which to express the implications of his own work. It is in this area 
        between the general climate and the specific findings that Spencer is the major 
        figure. Spencer was applying evolutionary principles to psychological phenomena 
        for years before Darwin published the Origin. The attention of Darwin's 
        circle was turned to man's body rather than his mind for twelve more years until 
        the Descent of Man appeared.[3] It was Spencer who provided the first, 
        and the most thorough, conception of adaptive, evolutionary psychology. His work 
        was more seminal than directly contributory. He argued for a consistent 
        application of empiricism but was characteristic of the parent tradition of 
        associationism in not actually employing the empirical method. He advocated 
        comparative and developmental studies but conducted none. He conceived 
        psychology as the study of the adaptation of organisms to their environments, 
        but failed to free himself completely from the epistemological bias of 
        associationism, being concerned with the origin of ideas, the forms of thought, 
        and a correspondence theory of truth.
      One measure of Spencer's significance, therefore, is 
        through his influence on major figures in three aspects of the new biological 
        psychology: George J. Romanes in animal and comparative psychology, William 
        James in functional psychology, and John Hughlings Jackson in sensory-motor 
        psychophysiology.
      G. J. Romanes wrote the first modern animal psychology 
        based on

      the evolutionary theory and employing the empirical 
        method.[1] He set out to trace the main outlines for mental evolution, as Darwin 
        had done for bodily evolution. In his first volume, Animal Intelligence  (1882) his purpose is to lay the foundations in comparative psychology for an 
        understanding of mental evolution. He starts from Darwin and Spencer. 'With the 
        exception of Mr Darwin's admirable chapters on the mental powers and moral 
        sense, and Mr Spencer's great work on the Principles of Psychology, there has 
        hitherto been no earnest attempt at tracing the principles which have been 
        probably concerned in the genesis of Mind.’[2] The second volume of Romanes' 
        work is concerned with mental evolution proper and finally takes the position 
        that was still equivocal in Bain and Spencer.
      I am in no wise concerned with 'the transition from the 
        object known to the knowing subject', and therefore I am in no wise concerned 
        with any of the philosophical theories which have been propounded upon this 
        matter. . . . I cannot too strongly impress upon the memory of those who from 
        previous reading are able to appreciate the importance of the distinction, that 
        I thus intend everywhere to remain within the borders of psychology, and nowhere 
        to trespass upon the grounds of philosophy.[3]
      Darwin provided the main inspiration and many of the 
        data for these volumes and made his extensive notes on instinct available to 
        Romanes. The second major source in Mental Evolution in Animals (1883) is 
        Spencer, who provides the starting point of the discussion on instinct as well 
        as the psychological framework of evolutionary associationism which Romanes 
        adopts.
      Comparative psychology developed from these beginnings 
        to a more rigorous formulation by C. Lloyd Morgan, who drew heavily on Romanes' 
        work and was his literary executor. Morgan improved on Romanes' rather 
        uncritical anecdotal method and anthropomorphism.[4] The next developments in 
        animal psychology involve support for Morgan's methods by Jacques Loeb, who put 
        forward the existence of ‘associative memory' as the point in the scale of 
        beings where animal life becomes conscious.[5] The introduction of the 
        puzzle-box method into comparative psychology by E. L. Thorndike in 1898 was the 
        point at which objective experimental methods were introduced into psychology, 
        and prepared the way for its absorption into behaviourism.[6]
      Behaviourism and modern learning theory may seem remote 
        from

      evolutionary associationism to the modern reader. It 
        may be useful to recall that the units of the conditioned reflex are new terms 
        for the basic concepts of sensory-motor psychophysiology. The extreme complexity 
        of current discussions and the sophisticated methods and techniques of work in 
        modern learning theory must not be allowed to obscure its conceptual basis. John 
        Dewey noted as early as i896, that the use of the reflex concept in psychology 
        was an admission that the sensory-motor view was basic to nerve structure and 
        function, as well as to experience and behaviour.[1] It is clear that, although 
        most studies of conditioning and learning depend on the evolutionary theory for 
        their relevance to human psychology, the evolutionary aspect of the discipline 
        has been largely ignored. However, the continued influence of associationism on 
        this tradition has recently been reviewed with results which bear on one's 
        appreciation of Bain and Spencer.
      In a chapter entitled 'Modern Concepts of Association', 
        Murphy begins by echoing Guthrie's belief that association is the only theory of 
        learning that has ever been proposed.[2] He reviews the work of the 
        behaviourists and learning theorists and shows that the central point of their 
        work has been the principle of association placed in the objective context of 
        the reflex paradigm. Stimulus-response psychology and the various schools of 
        conditioning and learning theory have added a great deal to the old domain: the 
        experimental method, various control procedures, quantification, and a 
        behaviourist emphasis on the periphery of the organism. That is, they have made 
        the study of association an objective science whose data are in the external 
        world of objects and behaviour. New concepts such as 'operant' have been 
        elaborated from Thorndike's restatement of Bain's early law of effect. However, 
        the central conception has remained associationist. This unites Pavlov, Watson, 
        Skinner, and a host of lesser figures. Reflecting on the century since Bain 
        brought associationism into relation with physiology and Spencer with evolution, 
        Murphy concludes,
      If one had to summarize the main trend as it now exists 
        in the middle of the century, it would almost certainly have to be to the effect 
        that despite huge and continuous protests of strong and active personalities, 
        the conceptions of Spencer and Bain a hundred years ago remain dominant.
      . . . An enormous amount of sophistication has gone 
        into experimental and quantitative refinement of the theory of association; but 
        the framework set up by the associationists remains.[3]

      Spencer's role as a major source of James' founding of 
        functional psychology cannot be demonstrated in detail here. Once again, 
        however, Darwin provided the general issue and influence, while Spencer supplied 
        its psychological embodiment, and Bain the specific theory of activity which was 
        developed in the writings of early pragmatists and was expressed in William 
        James' Principles of Psychology (1890). Among the sources for this work, 
        Spencer played the double role of being its major one for the adaptive, 
        evolutionary view and-through Hughlings Jackson and Ferrier-for the specific 
        sensory-motor psychophysiology of its early chapters. James grew increasingly 
        critical of Spencer's vagueness on matters of general evolution, but he had 
        nothing but praise for the fact that Spencer stressed its universality.[1] 'To 
        Spencer is certainly due the immense credit of having been the first to see in 
        evolution an absolutely universal principle.'[2] James' biographer reports that 
        'the writings of Spencer furnished the most important part of his early 
        philosophical pablum'.[3] He read the First Principles between 1860 and 
        1862, and its initial influence was very stimulating.[4] James used Spencer's  Principles of Psychology as the text for his first course in physiological 
        psychology at Harvard (1876-77), and his first original publication was a 
        commentary on Spencer.[5] His course on the philosophy of evolution used 
        Spencer's First Principles as a text beginning in 1880 and as late as 
        1897.[6] It should be stressed that James was very critical of Spencer's 
        detailed formulations. However, Spencer's aims and the topics he discussed were 
        just those which most interested James. As his own thought developed he retained 
        these interests while rejecting many of Spencer's answers and reacting strongly 
        against his intellectual muddiness and pretensions toward explaining 
        everything.[7]
      The influence of Spencer's Principles of Psychology on James' work of the same title written thirty-five years later is clear 
        from the following remarks in James' introductory chapter.
      On the whole, few recent formulas have done more real 
        service of a rough sort in psychology than the Spencerian one that the essence 
        of mental life and of bodily life are one, namely, 'the adjustment of inner to 
        outer relations'. Such a formula is vagueness incarnate; but because it takes 
        into account the fact that minds inhabit environments which act on them and on 
        which they in turn react; because, in short, it takes mind in the midst of all 
        its concrete relations, it is immensely more fertile than the old-fashioned

      ‘rational psychology', which treated the soul as a 
        detached existent, sufficient unto itself, and assumed to consider only its 
        nature and properties.[1]
      James' final evaluation of Spencer was harsh, but he 
        continued to admire his psychological work:
      My impression is that, of the systematic treatises, the 
        'Psychology' will rank as the most original. Spencer broke new ground here in 
        insisting that, since mind in its environment have evolved together, they must 
        be studied together. He gave to the study of mind in isolation a definitive 
        quietus, and that certainly is a great thing to have achieved. To be sure he 
        overdid the matter, as usual, and left no room for any mental structure at all, 
        except that which passively resulted from the storage of impressions received 
        from the outer world in the order of their frequency by fathers and transmitted 
        to their sons. The belief that whatever is acquired by sires is inherited by 
        sons, and the ignoring of purely inner variations, are weak points; but to have 
        brought in the environment as vital was a master stroke.[2]
      Functional psychology was born of a union of this 
        formulation and a more active view of adaptation, which James drew from Bain.
      The work of Bain and Spencer eliminated the credibility 
        of a simple labula rasa psychology. Bain's careful study of the role of 
        muscular motion in learning undermined the persistent belief in passive 
        sensationalism, while Spencer's evolutionary view revealed the absurdity of a 
        psychology which confines itself to individual experience. Almost exactly a 
        century after Condillac's statue provided the basis of a plausible explanation 
        of learning,[3] psychologists could point to this 'thought experiment' as the 
        opposite of a fruitful hypothesis. Bain and Spencer showed convincingly that 
        organisms feel, know, and act as they do, by virtue of what they have inherited 
        as a result of the vicissitudes of their species, and by virtue of what they 
        have already done.
      Bain and Spencer dominate the union of associationism 
        with biology. Bain brought about its integration with sensory-motor physiology. 
        Spencer reinforced this and based the new sensory-motor psychophysiology on an 
        evolutionary foundation. Magoun has convincingly argued that to their 
        contemporaries and early successors, Spencer's ideas of the evolution of the 
        brain and its functions were fully as

      3 Condillac had tried to prove the sensationalist 
        thesis by adding the senses, one by one, to a marble statue, and argued that the 
        result accounted for all psychological phenomena. See Condillac, 1930; above, p. 
        15.

      significant and influential as Darwin’s, if not more 
        so, in the development of concepts of evolution of the brain and behaviour.[1] 
        This aspect of Spencer’s work will be pursued through its influence on Hughlings 
        Jackson, and its union with other evidence for cerebral localization in the 
        writings of Ferrier to provide an experimental sensory-motor psychophysiology 
        based on the assumption of cerebral localizations.[2]
      1 Magoun, 1960, p. 204; 1961, p. 16; see also Wiener, 
        1949.
      2 There are three further aspect of Spencer’s influence 
        which should be mentioned (1) Spencer’s social theory and its influence on 
        Social Darwinism has been explored by Hofstadter.(2) His role in the foundation 
        of modern sociology along with Auguste Comte, who also began his work as a 
        student of Phrenology and remained loyal to Gall, deserves a full study. See 
        Greene (1959); Burrow (1966), ch. 6. In addition to his seminal influence in 
        functional psychology, Spencer’s influence on Durkheim and others was of 
        fundamental importance in the development of functionalism in sociology and 
        social anthropology. (3) His theory of psychophysical parallelism, through 
        Jackson’s ‘Law of Concomitance’, provided the form of Freud’s psychoanalytic 
        theory and provided the position which Freud held in the mind-body problem from 
        his first work (on Aphasia, 1891) to his last (Outline of 
          Psychoanalysis, 1940). This aspect of relations among Spencer, Jackson, and 
        Freud should be pursued as part of a more general study of the central role 
        psychophysical parallelism has played in the history of neurology, psychiatry, 
        and psychoanalysis.
