It does not follow, however, that the term “unconscious” is the one that should be chosen. On the contrary, as unconscious has two distinct and different meanings (that pertaining to unawareness and that which is non-psychological) it is a very undesirable term if we wish to be precise in our terminology. That we should have a term which shall precisely define ideas which are not in awareness and which shall distinguish them from physiological processes is necessitated by the fact that such ideas in themselves form a distinct field of investigation. The term “subconscious” is commonly used, excepting by German writers, to characterize these coconscious ideas. In fact, by some French medical writers, particularly Janet, it is very precisely limited to such ideas. By other authors it is employed in this sense and also to include the physical residua of experiences, and sometimes with the additional meaning of unconscious physiological neurograms, or processes, which it defines—in fact, to denote any conserved experience or process outside of consciousness. On the other hand, among these authors, some do not admit the validity of the concept of coconscious ideas, but interpret all so-called subconscious manifestations as the expression of the physiological functioning of physiological neurograms in which the experiences of life are conserved. Subconscious and unconscious are, therefore, quite commonly, but not always, employed as synonyms to define two or three different classes of facts. For practical reasons, as already stated, it is desirable to have a term which shall embrace all classes of facts, and of the two terms in common use, subconscious and unconscious, the former is preferable, as it is not subject to the double meaning above mentioned. I, therefore, use the term subconscious in a generic sense to _include_ (_a_) _coconscious ideas or processes_; (_b_) _unconscious neurograms, and_ (_c_) _unconscious processes_. Of course it is only a matter of terminology. The conceptual facts may then be thus classified: { (synonym: subconsciousideas.) { The coconscious { { { {a: Conserved dormant { { {neurograms or neural { { {dispositions. The subconscious { { { {b: Active functioning { The unconscious { {neurograms or neural { { processes. { { (synonym: unconscious { { processes.)
