Ange, I'm going to not only agree with you, but trump you one and say that it's not only temperament which is a motivating force in the creation of art, but even more important is the notion of taste. Any avantist who made a point of killing art did it with impeccable taste, hence its ultimate absorption into the canon of art. Take Duchamp. Every objet trouvé of his reeked of his taste. What if, for example, Duchamp had chosen a light bulb (as Johns did later with impeccable taste) instead of a urinal? a shoe (as Warhol did later with impeccable taste) instead of a bicycle wheel? What made these anti-art objects essentially Duchampian was his great taste. In writing, Jackson Mac Low, too, had amazing taste: he made all the right choices to free himself of choice-making.
Contrary to my own claims, I'm always banging my head against the realization that no matter how hard you try, you can never remove the individual from art. I have made arguments for ego-less art, found art, art driven by chance operations and many other strains, but in fact there's always someone behind the curtain, manning the machines. I have yet to encounter tasteless art. We try too hard, which is why I'm always in favor of doing less. If there's one thing that the avant-garde has shown us, it's that regardless of form, non-expression is impossible.
