To the modern painter–
I’d agree that Duchamp’s concepts were mostly cold japes– I could name a few painters who gave at least a real college try at a response to the challenge of Duchamp’s reduction of painting (and all of life, by extension toward Leary’s talk of games perhaps) to a mostly self-referential game. But it’s the way you do it that counts when the art world is showing noticeable breaks in its facade from its repeated, constant, daily toilet-scraping bows to austere experience.
