- "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 as a bad emotion is still an emotion".
- "I was interested in ideas, not in visual products. I wanted to put painting again in the service of the mind".
- "The creative act is not formed by the artist alone; the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act".
- "In the creative act, the artist goes from intention to realization through a chain of totally subjective reactions".
- "I don't believe in art. I believe in artists".
- "I consider painting as a means of expression, not as a goal".
- "It's true, of course, humor is very important in my life, as you know. That's the only reason for living, in fact".
The Creative Act by Marcel Duchamp
