Indeed, our society, which has seemed so freedom-giving and passive in its attitudes toward the artist really makes extraordinary demands upon him: on the one side, to be free in some vague spiritual sense, free to act only as an artist, and yet on the other side to be rigorously tested as to whether the freedom he has achieved is great enough to be more solidly dependable than a government's financial structure... No wonder that modern painters, in view of these curious relations to society, have taken art matters into their own hands, decides for themselves what art is, what its subjects are to be, and how they are to be treated. Art like love is an active process of growth and development.
