Paul Cezanne: "I could paint for a thousand years without stopping and I would still feel as though I knew nothing."
Edgar Degas: "Only when he no longer knows what he is doing does the painter do good things.... To draw, you must close your eyes and sing."
Georges Braque: "In art there is only one thing that counts: the bit that can’t be explained."
