The artist who improves indeed develops creative faculty, and this is rooted in that spirit which is the spirit of the Creator. To improve upon nature is to add to nature that which human nature has produced by a certain angle of vision. Improving is the perfection of nature. The path of the improver is risky. He sometimes has to produce what the human eye has never seen. Therefore his art, instead of appealing to the sense of beauty, often appeals to the sense of curiosity; and instead of bringing satisfaction, which must come through beauty, it may create a feeling of marvel. The artist must have a wonderful grace of form in order to improve to satisfaction.
