Therefore, repetition is impossible, and recovery is never more than partial or approximate. All these belong to the physical side of memory. But memory has another side, viz., the noumenal. Experience once had can never be as though it had not been. It has wrought its effect, and if it is ever in any way recovered or recalled it is a reminiscence.
Physical memory is to reminiscence what the elements of a mixture are to a compound.
In one we have separate details, and an orderly sequence of relations. These belong to time. Memory belongs to the personality of time and sense. Reminiscence belongs to the permanent individual. Memory is the field-notes in the realm of thought.
