Among our articles of lazy hardware, I recommend the faucet that stops dripping when no one is listening to it. - Marcel Duchamp

First, there's the idea of the movement of the train [in his painting 'Nude (Study), Sad Young Man on a Train', (made in 1911–12)] and then that of the sad young man who is in a corridor and who is moving about; thus there are two parallel movements corresponding to each other. Then, there is the distortion of the young man—I had called this elementary parallelism. It was a formal decomposition; that is, linear elements following each other like parallels and distorting the object. The object is completely stretched out, as if elastic. The lines follow each other in parallels, while changing subtly to form the movement, or the form of the young man in question. I also used this procedure in the [painting] 'Nude Descending a Staircase'.

Since the tubes of paint used by the artist are manufactured and ready made products we must conclude that all the paintings in the world are 'readymades aided' and also works of assemblage.

I don't believe in art. I believe in the artist.
