The traditional psychology of the original separate soul, mind or consciousness is in truth a reflex of conditions which cut human nature off from its natural objective relations. It implies first the severance of man from nature and then of each man from his fellows. The isolation of man from nature is duly manifested in the split between mind and body--since body is clearly a connected part of nature. Thus the instrument of action and the means of the continuous modification of action, of the cumulative carrying forward of old activity into new, is regarded as a mysterious intruder or as a mysterious parallel accompaniment. It is fair to say that the psychology of a separate and independent consciousness began as an intellectual formulation of those facts of morality which treated the most important kind of action as a private concern, something to be enacted and concluded within character as a purely personal possession. The religious and metaphysical interests which wanted the ideal to be a separate realm finally coincided with a practical revolt against current customs and institutions to enforce current psychological individualism. But this formulation (put forth in the name of science) reacted to confirm the conditions out of which it arose, and to convert it from a historic episode into an essential truth. Its exaggeration of individuality is largely a compensatory reaction against the pressure of institutional rigidities. Any moral theory which is seriously influenced by current psychological theory is bound to emphasize states of consciousness, an inner private life, at the expense of acts which have public meaning and which incorporate and exact social relationships. A psychology based upon habits (and instincts which become elements in habits as soon as they are acted upon) will on the contrary fix its attention upon the objective conditions in which habits are formed and operate. The rise at the present time of a clinical psychology which revolts at traditional and orthodox psychology is a symptom of ethical import. It is a protest against the futility, as a tool of understanding and dealing with human nature in the concrete, of the psychology of conscious sensations, images and ideas. It exhibits a sense for reality in its insistence upon the profound importance of unconscious forces in determining not only overt conduct but desire, judgment, belief, idealization.
