A large picture can give us images of things, but a relatively small one can best re-create the instantaneous unity of nature as a view — the unity o… - Clement Greenberg

Realistic, naturalistic art had dissembled the medium, using art to conceal art; Modernism used art to call attention to art.

Perhaps the greatest change that industrialism (along with Protestantism and rationalism) has made in daily life is to separate work from leisure in a radical and almost absolute way. Once the efficacy of work began to be more clearly and fully appreciated, work had to become more efficacious in itself — that is, more efficient. To this end, it had to be more sharply separated from everything that was not work; it had to be made more concentratedly and purely itself — in attitude, in method and, above all, in time. Moreover, under the rule of efficiency, seriously purposeful activity in general tended to become assimilated to work. The effect of all this has been to reduce leisure to an occasion more exclusively of passivity, to a breathing spell and interlude; it has become something peripheral.

"Purity" of and in art — any art, including music and dance — is an illusory notion, of course. It may be remotely conceivable or imaginable, but it can't be realized because it can't be recognized any more than a "pure" human being or a "pure" (or, for that matter, gratuitous) act can be. All the same, for Western art in its Modernist phase "purity" has been a useful idea and ideal, with a kind of logic to it that has worked, and still works, to generate aesthetic value and maintain aesthetic standards as nothing else in our specializing culture has over the last hundred-odd years. But this logic has also worked to exclude the decorative — the decorative insofar as it functions solely as decoration. It's as though aesthetic value, quality, could be preserved only by concentrating on "absolute" or "autonomous" art: thus on visual art — including even architecture — that held and moved and stirred the beholder as sheer decoration could not. Decoration is asked to be "merely" pleasing, "merely" embellishing, and the "functional" logic of Modernism leaves no room, apparently, for such "mereness." This is part of the pity of Modernism, one of the sacrifices it enjoins....
