No art? But still an artist!
What is it that a man of such genius doesn’t actually know what the meaning of the craft he truly is a master of is? Doesn’t he know? Or does he know that he can’t know?
Maybe it is a matter of knowing, or as I suggest, not-knowing. M.C. Escher can know what science is, because it is a set of rules and computable results logically connected, while art surely is not.
