There are, however, a large number of emotional phenomena occurring in pathological conditions which can only be intelligibly interpreted as being due to the residua of previously conscious experiences functioning as a subconscious process. These phenomena we shall have occasion to review in succeeding lectures. They are too complex to enter upon at this stage. Aside, then, from these word-reactions we have a sufficient number of other phenomena, such as I have cited, which indicate that conscious experiences when conserved must persist in a form capable of exciting purely physiological reactions without the experiences themselves rising into consciousness again as memory. The form must also be one which permits of their functioning as intelligent processes although not within the conscious field of awareness of the moment. As a final summing up of the experiments and observations of the kind which I have thus far cited, dealing with forgotten experiences, we may say that they lead us to the following conclusions: 1. That conservation is something very different from reproduction. 2. A given experience is conserved through the medium of some kind of residuum of that experience. This residuum must have a specific existence independent of consciousness, in that it is capable of specific and independent functioning, coincidentally with and outside of the consciousness of any given moment. Its nature must be such that it can incite through specific processes the following phenomena in none of which the conscious processes of the moment take part as factors: (a) Specific memory for the given experience expressed through the established physiological mechanisms of external expression (speech, writing, gestures) after the manner of a mnesic process. (b) A mnesic hallucination which is a representation of the antecedent perceptual experience but after having undergone translation into terms of another sense. (c) A mnesic hallucination in which the original experience appears synthesized with various other experiences into an elaborate representation of a complex experience, or secondarily elaborated into a symbolism, allegory or other fabrication. (d) Mnesic phenomena which are a logical continuation of the antecedent conscious experiences and such as ordinarily are produced by conscious processes of thought—reasoning, imagination, volition (mathematical calculations, versification, fabrication, etc.). (e) Physical phenomena (paralyses contractures, vasomotor disturbances, etc.). In other words a specific experience while in a state of conservation and without being reproduced in consciousness can incite or induce processes which incite these and similar phenomena. ----- Footnote 45: Lecture III, p. 58.
