To follow a little farther this relation between the purposive and fulfilling aspects of experience, it is of course apparent that the idea as the purpose, the "plan of action," must as a function go over into the fulfilling experience. My purpose to sing the melody must remain, in so far as the action is a conscious one, until the melody is sung. I say "as a function," for the specific content of this purpose is continuously changing. The purpose is certainly not the same in content after half the melody has been sung as it is at the beginning. This means that the purpose is being progressively fulfilled; and as part of the purpose is fulfilled each moment, so a part of the original content of the idea drops out; and when the fulfilling process of this particular purpose is complete, or is suspended--for, in Mr. Royce's view, it never is complete in human experience--that purpose then gives way to some other, perhaps one growing out of it, but still one regarded as another. A purpose realized, fulfilled, cannot persist as a purpose. We may desire to repeat the experience in memory; _i. e._, instead of singing aloud, simply, as Mr. Royce says, "silently recall and listen to its imagined presence." But here we must remember that the memory experience, as such, is not an idea in the logical sense at all. It is an immediate experience that is fulfilling the idea of the song which constitutes the purpose to recall it, just as truly as the singing aloud fulfils the idea of singing aloud. Shouting, whistling, or "listening in memory to the silent notes" may all be equally immediate, fulfilling experiences. Doubtless the idea as purpose involves memory, as Mr. Royce says.[176] But it is a memory used as a purpose, and it is just this use of the memory material as a purpose that makes it a logical idea. In its content the purposive idea is just as immediate and as mechanical as any other part of experience. "Psychology explains the presence and the partial present efficacy of this purpose by the laws of motor processes, of habit, or of what is often called association."[177] Here "idea," however, simply means, as Mr. Royce takes it in his second statement, conscious content of any sort. But this is not the meaning of "idea" in the logical sense. The logical idea is a conscious content used as an organizer, as "a plan of action," to get other contents. If, for example, in the course of writing a paper one wishes to recall an abstract distinction, as the distinction dawns in consciousness, it is not an idea in the logical sense. It is just as truly an immediate fulfilling experience as is a good golf stroke. So in the mathematician's most abstruse processes, which Mr. Royce so admirably portrays, the results for which he watches "as empirically as the astronomer alone with his star" are not ideas in the logical sense; they are immediate, fulfilling experiences.[178] The distinction between the
