"What I have in mind is that art may be bad, good or indifferent, but, whatever adjective is used, we must call it art, and bad art is still art in the same way that a bad emotion is still an emotion.

Therefore, when I refer to 'art coefficient', it will be understood that I refer not only to great art, but I am trying to describe the subjective mechanism which produces art in the raw state .. .`a l'e`tat brut - bad, good or indifferent."
-Marcel Duchamp (excerpt from The Creative Act)
