“The best art always comes unbidden.”

Context: Business art is the step that comes after Art. I started as a commercial artist, and I want to finish as a business artist. After I did the thing called 'art' or whatever it's called, I went into business art. I wanted to be an Art Businessman or a Business Artist. Being good in business is the most fascinating kind of art. During the hippies era people put down the idea of business – they'd say 'Money is bad', and 'Working is bad', but making money is art and working is art and good business is the best art.

Context: In art, immorality cannot exist. Art is always sacred even when it takes for a subject the worst excesses of desire; since it has in view only the sincerity of observation, it cannot debase itself. A true work of art is always noble, even when it translates the stirrings of the brute, for at that moment, the artist who has produced it had as his only objective, the most conscientious rendering possible of the impression he has felt.
