The doctrines of Freud seem to be regarded by his school as covering all the activities of the mind and making a complete, though of course not necessarily exhaustive, survey of the whole field. I have already pointed out directions in which it appears to me that inquiries by other methods than those of the psycho-analytic school can be pursued with success. Regarded in a broad way, the Freudian body of doctrine which I have already ventured to describe as essentially an embryology of the mind gives one the impression of being mainly descriptive and systematic rather than dynamic, if one may with due caution use such words. It is able to tell us how such and such a state of affairs has arisen, what is its true significance, and to describe in minute detail the factors into which it can be analysed. When the question of acting upon the mind is raised its resources seem less striking. In this direction its chief activities have been in the treatment of abnormal mental states, and these are dealt with by a laborious process of analysis {90} in which the subject’s whole mental development is retraced, and the numerous significant experiences which have become excluded from the conscious field are brought back into it. When the unconscious processes which underlie the symptoms have been assimilated to the conscious life of the patient, the symptoms necessarily disappear, and the patient’s mind gains or regains the “normal” condition. However precious such a cure may be to the patient, and however interesting to the physician, its value to the species has to be judged in relation to the value of the “normal” to which the patient has been restored—that is, in relation to the question as to whether any move, however small, in the direction of an enlargement of the human mind has been made. Until some clearer evidence has been furnished of a capacity for development in this direction the Freudian system should, perhaps, be regarded as more notably a psychology of knowledge than a psychology of power.
