In the 'Nude Descending a Staircase,' I wanted to create a static image of movement: movement is an abstraction, a deduction articulated within the painting, without our knowing if a real person is or isn't descending an equally real staircase.

The great problem was the selection of the readymade. I needed to choose an object without it impressing me: that is to say, without it providing any sort of aesthetic delectation. Moreover, I needed to reduce my own personal taste to absolute zero.

In French, there is an old expression, la patte, meaning the artist's touch, his personal style, his 'paw'. I wanted to get away from la patte and from all that retinal painting.
