The foregoing enumeration of the chief doctrines of the Freudian psychology is intended to be no more than a mere outline to serve as a basis for certain comments which seem to be relevant to the general argument of this essay. The point of view from which this slight sketch is made, that of an interested but detached observer, is naturally somewhat different from that of the actual authorities themselves. Here it is desired to get the broadest possible view in the most general terms, and as we have no concern with immediate problems of practical therapeutics—which remain at least the chief preoccupation of writers of the psycho-analytic school—an effort has been made to avoid the use of the rich and rather forbidding technical vocabulary in which the writings of the school abound. It may well be that this generalized method of description has yielded an ill-proportioned or distorted picture. The subject has proved to be so much at the mercy of prejudice that the least impassioned spectator, however completely he may believe himself to be free from advocacy or detraction, is far from being able to claim immunity from these influences.

Keeping constantly in mind this general caution, which is at least as necessary in the field of criticism as in that of mere description, we may pass on to make certain comments on the psychology of Freud which are relevant to the general argument being followed out here. {76}

A discussion in any way detailed of this immense subject is very obviously impossible here, but it is desirable to say a few words as to the general validity of Freud’s chief thesis. However much one may be impressed by his power as a psychologist and his almost fierce resolution to get at the actual facts of mental processes, one can scarcely fail to experience in reading Freud’s works that there is a certain harshness in his grasp of facts and even a trace of narrowness in his outlook which tend to repel the least resistant mind and make one feel that his guidance in many matters—perhaps chiefly of detail—is open to suspicion. He seems to have an inclination for the enumeration of absolute rules, a confidence in his hypotheses which might be called superb if that were not in science a term of reproach, and a tendency to state his least acceptable propositions with the heaviest emphasis as if to force belief upon an unwilling and shrinking mind were an especial gratification. All these traits of manner—at the worst mere foibles of a distinguished and successful investigator—appear to exercise some considerable effect on the acceptance his writings meet with, and are perhaps indications in which direction, if he is open to fallacy, such might be looked for.

Nevertheless with regard to the main propositions of his system there can be little doubt that their general validity will be increasingly accepted. Among such propositions must be put the conception of the significance of mental conflict, the importance of the emotional experiences of infancy and childhood in the determination of character and the causing of mental disease, and his conception of the general structure of the mind as comprising conscious and unconscious fields.

The comments which I shall venture to make upon the work of Freud will be such as are suggested {77} by the biological point of view of which this essay is intended to be an exposition. The standard of interest upon which they are based will therefore necessarily differ to some extent from that which is usually adopted in writings of the psycho-analytic school.

To the biologist perhaps the most striking characteristic of the work of this school is its complete acceptance of what one may call the human point of view. It seems to be satisfied that no useful contribution to psychology is to be obtained outside the limits of human feeling and behaviour, and to feel no impatience to expand its inquiries into a still larger field. It is not that the school has failed to show an extremely vigorous movement of expansion. Beginning as a mere province of medicine, and while its foothold there was still far from general recognition, it invaded the regions of general psychology, of æsthetics, ethnology, the study of folklore and myth, and indeed of all matters in which it could find its essential material—the records of human feeling and conduct. Beyond the human species it has shown remarkably little of this aggressive spirit, and it seems to feel no need of bringing its principles into relation with what little is known of the mental activities of the non-human animals.

The absence of any strong pressure in the direction of establishing a correlation of all mental phenomena, whether human or not, is not a matter of merely theoretical interest. The actual practical success to be obtained to-day in such an attempt might possibly be insignificant and yet of great value in moulding the whole attitude of mind of the investigator towards matters lying wholly within the sphere of human psychology. However much one may be impressed by the greatness of the edifice which Freud has built up and by the soundness of {78} his architecture, one can scarcely fail, on coming into it from the bracing atmosphere of the biological sciences, to be oppressed by the odour of humanity with which it is pervaded. One finds everywhere a tendency to the acceptance of human standards and even sometimes of human pretensions which cannot fail to produce a certain uneasiness as to the validity, if not of his doctrines, at any rate of the forms in which they are expounded. The quality I am trying to describe is extremely difficult to express in concrete terms without exaggeration or distortion. To those who have approached Freud’s work solely by the path of medicine the idea that it can give any one the feeling of a certain conventionality of standard and outlook and of a certain over-estimation of the objectivity of man’s moral values will seem perhaps merely absurd. That this is an impression which I have not been able altogether to escape I record with a good deal of hesitation and diffidence and without any wish to lay stress upon it.

Psycho-analytic psychology has grown up under conditions which may very well have encouraged the persistence of the human point of view. Originally its whole activity was concentrated upon the investigation and treatment of disease. Many of its early disciples were those who had received proof of its value in their own persons, those, that is to say, who had been sufferers from their very susceptibility to the influence of human standards. The objective standard of validity by which the system was judged was necessarily that of the physician, namely the capacity to restore the abnormal mind to the “normal.” Normal in this sense is of course no more than a statistical expression implying the condition of the average man. It could scarcely fail, however, to acquire the significance of “healthy.” If once the statistically {79} normal mind is accepted as being synonymous with the psychologically healthy mind (that is, the mind in which the full capacities are available for use), a standard is set up which has a most fallacious appearance of objectivity. The statistically normal mind can be regarded only as a mind which has responded in the usual way to the moulding and deforming influence of its environment—that is, to human standards of discipline, taste, and morality. If it is to be looked upon as typically healthy also, the current human standards of whose influence it is a product must necessarily be accepted as qualified to call forth the best in the developing mind they mould. Writers of the psycho-analytic school seem in general to make some such assumption as this.

III

The conception of mental conflict is the central feature of the Freudian system. Of its importance and validity there can be no doubt. In a general way the idea is familiar and even commonplace, but Freud had developed it and shown how deeply the principle penetrates the structure and development of the mind from the earliest period and to an extent quite unsuspected by earlier psychologists.
