In art one idea is as good as another.

In art, one idea is as good as another. If one takes the idea of trembling, for instance, all of a sudden most art starts to tremble. Michelangelo starts to tremble. El Greco starts to tremble. All the Impressionists start to tremble.

The idea of space is given to the artist to change if he can. The subject matter in the abstract is space.

Every so often, a painter has to destroy painting. Cezanne did it, Picasso did it with Cubism. Then Pollock did it. He busted our idea of a picture all to hell. Then there could be new paintings again.
