[79]. Of course, from a practical (clinical) point of view, it is of no consequence whether given phenomena are induced by coconscious or unconscious processes; the individual is not aware of either. Let me answer, however, a strange objection that has been made to such an inquiry. It has been objected that as it makes no practical difference whether the subconscious process, which induces a given phenomenon, is coconscious or unconscious, and as in many given cases it is difficult or impossible to determine the question, therefore, that such inquiries are useless. Plainly such an objection only concerns applied science, not science itself. It concerns only the practicing physician who deals solely with reactions. Likewise it makes no difference to the practicing chemist whether some atoms are positive and some negative ions, and whether on further analysis they are systems of electrons, and whether, again, electrons are points of electricity. The practical chemist deals only with reactions. Such questions, however, having to do with the ultimate nature of matter are of the highest interest to science. Likewise the nature of subconscious processes is of the highest interest to psychological science.

[80]. I have passed over the classical hysterical phenomena as they open a very large subject which needs a special treatment by itself. The subconscious processes underlying them, so far as they have been determined, are, as I have explained, admittedly coconscious, though some may be in part unconscious. They are too complicated to be entered into here.

[82]. Among these I might mention the names of a dozen or more well-known psychologists and physicians of experience and repute who have observed one or both of these cases. Through the kindness of Dr. G. A. Waterman I have had an opportunity to investigate a third case, one of his patients, who described similar coconscious “pictures” accompanying certain impulsive conscious acts. The pictures, when of persons, were described as “life size,” and were likened to those of a cinematograph. Also, as with one of my cases, suggested post-hypnotic actions were accompanied by such coconscious pictures representing in successive stages the act to be performed. An analysis of both the impulsive and the suggested phenomena seemed to clearly show that the pictures emerged from a deeper lying submerged process induced by the residuum of a dream and of the suggestion, respectively.

[83]. Cf. Lecture IV. These coconscious pictures are so varied and occur in so many relations that they need to be studied by themselves.

[84]. This, of course, so far as she could determine from the data of memory. The more correct interpretation probably is that the thoughts of the “secondary consciousness” were supplied by a still deeper underlying subconscious process, certain elements of which emerged as dissociated conscious states (not in the focus of attention). This same process probably was the real agent in doing the actual translation, and later thrust the necessary data into awareness in such fashion that the translation seemed to be performed consciously. If all the required data is supplied to consciousness the problem is thereby done.

[85]. The subject here, of course, refers not to experimental but to spontaneous solutions. When experimentally performed the whole problem was solved subconsciously. Furthermore, a memory of a detail of this kind of remote experiences obviously would not be reliable, but only immediately after an experience. In fact, spontaneous solutions sometimes occurred entirely subconsciously. (Cf. Lecture VII.) In the experimental calculation experiments the solution is made subconsciously in accordance with the prescribed conditions of the experiment. In other observations on this subject the coconscious pictures represented past experiences of the subject, much as do crystal visions, and suggest that these past experiences were functioning unconsciously.

[87]. Practically similar conditions I have found in B. C. A., and Miss B., though described by the subjects in different phraseology.

[88]. For instance, to take a sensational example, on one occasion in the midst of hilarity while singing, laughing, etc., she suddenly became depressed and burst into tears. What happened was this: It was a sorrowful anniversary, and in the “lower stratum” sad memories had been recurring during the period of hilarity. These memories had come into consciousness early in the morning, but she had resolutely put them out of her mind. They had, however, kept recurring in the lower stratum, and suddenly emerged into the upper stratum of consciousness with the startling effect described. More commonly, however, the emergence of the lower stratum is simply a shifting play of thought. It is interesting to note that censored thoughts and temptations are apt to go into the lower stratum and here with their affects continue at play. These sometimes reappear as dreams.
