Quotations and aphorisms by Donald Barthelme:
Painters, especially American painters since the Second World War, have been much more troubled, beset by formal perplexity, than American writers. They've been a laboratory for everybody.
I don't think you can talk about progress in art - movement, but not progress. You can speak of a point on a line for the purpose of locating things, but it's a horizontal line, not a vertical one.
