Note 69 — C. THEORETICAL PART

The recollection of this innervation expenditure will remain the essential part of the idea of this motion, and there will always be methods of thought in my psychic life in which the idea will be represented by nothing else than this expenditure. In other connections a substitute for this element may possibly be put in the form of other ideas, for instance the visual idea of the object of the motion, or it may be put in the form of the word-idea; and in certain types of abstract thought a sign instead of the full content itself may suffice.
