COMMENTS ON AN OBJECTIVE SYSTEM OF HUMAN PSYCHOLOGY
I
Until comparatively recent years the fact that what was called psychology did not even pretend to be of any practical value in affairs was tolerated by its professors and regarded as more or less in the nature of things. The science, therefore, outside a small class of specialists was in very dismal reputation. It had come to comprise two divergent schools, one which busied itself with the apparatus of the experimental physiologist and frankly studied the physiology of the nervous system, the other {70} which occupied itself with the faded abstractions of logic and metaphysics, while both agreed in ignoring the study of the mind. This comparative sterility may in a broad way be traced back to the one fundamental defect from which the science suffered—the absence of an objective standard by which the value of mental observations could be estimated. Failing such a standard, any given mental phenomenon might be as much a product of the observing mind as of the mind observed, or the varying degrees in which both of these factors contributed might be inextricably mixed. Of late years the much-needed objective standard has been sought and to some extent found in two directions. What I have called “human” psychology has found it in the study of diseases of the mind. In states of disease mental processes and mechanisms which had eluded observation in the normal appear in an exaggerated form which renders recognition less difficult. The enlightenment coming from the understanding of such pathological material has made it possible to argue back to the less obtrusive or more effectively concealed phenomena of the normal and more or less to exclude the fallacies of the observing mind, and, at any rate in part, to dissipate the obscurity which for so long had successfully hidden the actual mental phenomena themselves.
The most remarkable attack upon the problems of psychology which has been made from the purely human standpoint is that in which the rich genius of Sigmund Freud was and still is the pioneer. The school which his work has founded was concerned at first wholly with the study of abnormal mental states, and came into notice as a branch of medicine finding the verification of its principles in the success it laid claim to in the treatment of certain mental diseases. It now regards itself as possessing a body {71} of doctrine of general applicability to mental phenomena, normal or abnormal. These principles are the product of laborious and minute inquiries into the working of the mind, rendered possible by the use of a characteristic method known as psycho-analysis. This method, which constitutes a definite and elaborate technique of investigation, is looked upon by those who practise it as the sole means by which access can be obtained to the veritable phenomena of the mind, and as rendering possible a truly objective view of the facts. It is no part of my purpose to examine the validity of psycho-analysis as a scientific method. It is enough to notice that the exponents of it completely repudiate the teachings of what I have called “common-sense” psychology, that they maintain that objectivity in the collection and collation of psychical facts is in no way to be obtained by the light of nature but demands very special methods and precautions, and that their claims to the possession of a truly objective method appear to be open to verification or disproof by actual experiment in the treatment of disease. Whatever value, then, psycho-analysis may ultimately prove to possess in solving the peculiar difficulties of psychological research, the evolution of it marks a very definite advance in principle and shows that it is the product of a mind determined by whatever effort to get to close quarters with the facts.
The body of doctrine enunciated by Freud concerns us more directly than the peculiarities of his method. Some very general and summary account may therefore be attempted as illustrating the characteristics of this vigorous, aggressive, and essentially “human” school of research.
The Freudian psychology regards the mind of the adult as the outcome of a process of development the stages of which are within limits, orderly {72} and inevitable. The trend of this development in each individual is determined by forces which are capable of precise definition, and the final product of it is capable of yielding to expert examination clear evidence of the particular way in which these forces have acted and interacted during the developmental process. The mind of the adult, then, is like the body in bearing traces which betray to the skilled observer the events of its developmental history. Inconspicuous and apparently insignificant structures and peculiarities in the one no less than in the other prove to have had a meaning and a function in the past, however little significance their final form may seem to possess, and thus the psychologist is able to reconstruct the history of a given subject’s mind, although the most important stages of its development are hidden from direct observation as effectively as is the prenatal growth of the body.
It seems to be a fundamental conception of the Freudian system that the development of the mind is accompanied and conditioned by mental conflict. The infant is regarded as being impelled by instinctive impulses which at first are solely egoistic. From the earliest moments of its contact with the world resistance to the full indulgence of these impulses is encountered. With the growth and intensification of such impulses, the resistance from external interference—the beginnings of social pressure—becomes more formidable, until at a quite unexpectedly early age a veritable condition of mental conflict is established—egoistic impulses fatally pressing for indulgence regardless of their acceptability to the environment, while environmental influences bear equally heavily against any indulgence unwelcome to surrounding standards of discipline, taste, or morality.
Of the two parties in this conflict—the instinctive {73} impulse and the repressive force—the first, according to Freud, is wholly the product of the sex instinct. This instinct is conceived of as being much more active and potent in the infant and child than had been suspected by any previous investigator. The normal sexual interest and activity as manifested in the adult are developed out of the sexual impulse of the child by a regular series of modifications, which appear to be regarded as due partly to a process of natural development and partly to the influence of external repressive forces. In the infant the instinct is egocentric and the object of its interest is the individual’s own body; with the increase of the mental field consequent on enlarging experience the instinctive activity is externalized, and its object of interest changes so that the child acquires a specific inclination towards other individuals without distinction of sex; finally, as a last stage of development the instinctive inclination is localized to members of the opposite sex. This series of transformations is regarded as normal by Freud, and as essential to the appearance of the “normal” adult type. The evolution of this series is sensitive to interference by outside influences, and any disturbance of it either by way of anticipation or delay will have profound effects upon the ultimate character and temperament of the subject. The psychical energy of an instinct so important as that of sex is very great, and is not dissipated by the forces of repression brought to bear upon it, but transformed into activities ostensibly quite different and directed into channels having no obvious connection with their source. It is a fundamental characteristic of the mind to be able to accept these substitutes for the actual indulgence of the instinct, and to enjoy a symbolical gratification in manifestations which have no overt sexual significance. When development proceeds normally the {74} surplus energy of the sex instinct finds an outlet in activities of social value—æsthetic, poetic, altruistic; when development is interfered with the outflow of energy is apt to result in definite disease of the mind or in peculiarities of character scarcely to be distinguished therefrom.
Thus the mind of the adult, according to Freud, in addition to activities which are conscious and fully accessible to the subject, carries on activities and holds memories which are unconscious and totally inaccessible to the subject by any ordinary method of introspection. Between these two fields there is a barrier sedulously guarded by certain repressive forces. The unconscious is the realm of all the experiences, memories, impulses, and inclinations which during the subject’s life have been condemned by the standards of the conscious, have proved incompatible with it and have therefore been outlawed from it. This banishment in no way deprives these excluded mental processes of their energy, and they constantly influence the feelings and behaviour of the subject. So strict, however, is the guard between them and the conscious that they are never allowed to pass the barrier between one sphere and the other except in disguised and fantastically distorted forms by which their true meaning is closely concealed. It has been perhaps Freud’s most remarkable thesis that dreams are manifestations of this emergence of desires and memories from the unconscious into the conscious field. During sleep the repressing force which guards the frontier between conscious and unconscious is weakened. Even then, however, such ideas as emerge into the conscious can do so only in a worked up and distorted form, so that their significance can be disengaged from the grotesque jumble of the actual dream only by a minute inquiry according to a difficult and highly technical method. {75} By this method, however, is to be obtained a deep insight into the otherwise irrecoverable emotional history of the individual, the structure of his temperament, and, if he is mentally abnormal, the meaning of his symptoms.
