The best painters, as they progress in reputation and towards perfection, are found to dispense more and more with the technique of the art, for simpler methods. Simplicity never fails to charm.
Freedom, individualism and being yourself so long as you don't hurt another's physical person or property: The true artist is a man who believes absolutely in himself, because he is absolutely himself.
In art, and in the higher ranges of science, there is a feeling of harmony which underlies all endeavor. There is no true greatness in art or science without that sense of harmony.
