There are times when the idea is of little worth—but should be noted;—on further reflection, however, it is fair to discard it. At other times the idea seems weak, but later, re-examined with renewed breath, something valuable is drawn from it, and the weak is shown to be an important spark. Other times the mind manifests itself clearly, and the idea seems fair—from these the bulk of a work is extracted. And still other times, the mind manifests itself with such impetus that the artist, by restraining it, and not immediately focusing on what it tries to say, commits a crime against himself, and wastes what he can best extract from his mental manifestations. Attention and method are not enough; for the best use of the mind, is needed a disposition that goes against what is convenient.
