The idea of an isolated American painting , so popular in this country during the thirties, seems absurd to me, just as the idea of a purely American mathematics or physics would seem absurd... And in another sense, the problem doesn't exist at all; or, if it did, would solve itself: An American is an American and his painting would naturally be qualified by the fact, whether he wills or not. But the basic problems of contemporary painting are independent of any one country.
