Rh governing present-day psychology and to test their relation to our theories. The question of the unconscious in psychology is, according to the authoritative words of Lipps, less a psychological question than the question of psychology. As long as psychology settled this question with the verbal explanation that the "psychic" is the "conscious" and that "unconscious psychic occurrences" are an obvious contradiction, a psychological estimate of the observations gained by the physician from abnormal mental states was precluded. The physician and the philosopher agree only when both acknowledge that unconscious psychic processes are "the appropriate and well-justified expression for an established fact." The physician cannot but reject with a shrug of his shoulders the assertion that "consciousness is the indispensable quality of the psychic"; he may assume, if his respect for the utterings of the philosophers still be strong enough, that he and they do not treat the same subject and do not pursue the same science. For a single intelligent observation of the psychic life of a neurotic, a single analysis of a dream must force upon him the unalterable conviction that the most complicated and correct mental operations, to which no one will refuse the name of psychic occurrences, may take place without exciting the consciousness of the person. It is true that the physician does not learn of these unconscious processes until they have exerted such an effect on consciousness as to admit communication or observation. But this effect of consciousness may show a psychic character widely differing from the unconscious process, so that the internal perception cannot possibly recognise the one as a substitute for the other. The physician must reserve for himself the right to penetrate, by a process of deduction, from the effect on consciousness to the unconscious psychic process; he learns in this way that the effect on consciousness is only a remote psychic product of the unconscious process and that the latter has not become conscious as such; that it has been in existence and operative without betraying itself in any way to consciousness.
