A painting is not a picture of an experience; it is an experience. - Mark Rothko

But the most common error among the whole-hearted abstractionists nowadays [in 1946] is to mistake the medium for an end in itself, instead of a means. On the other hand, the surrealists erred in supposing that one can do without a medium, that in attacking the medium one does not destroy just one means for getting into the unknown. Color and space relations constitute such a means because from them can be made structures which exhibit the various patterns of reality.

[O]ne must agree with Rilke when he says that with 'nothing can one touch a work of art so little as with critical words...'. It was Marcel Duchamps who was critical, when he drew a moustache on the Mona Lisa. And so was Mondrian when he dreamed of the dissolution of painting, sculpture, and architecture into a transcendent ensemble.

It is a widely accepted notion among painters that it does not matter what one paints as long as it is well painted. This is the essence of academism. There is no such thing as good painting about nothing. We assert that only that subject matter is valid which is tragic and timeless. That is why we profess spiritual kinship with primitive and archaic art.
