If I didn't think what I was doing had something to do with enlarging the boundaries of art, I wouldn't go on doing it.

I like food because you can change it. I mean, there is no such thing as a perfect lamb chop; you can make all types of lamb chops. And that's true of everything. And people eat it and it changes and disappears.

I started to draw buildings. I called them Proposed Colossal Monuments - they weren't for real, not for actual building. It was more a critique of architecture.

I am for an art that grows up not knowing it is art at all.

My rule was not to paint things as they were. I wasn't copying; I was remaking them as my own.

I am for an art that takes its form from the lines of life itself, that twists and extends and accumulates and spits and drips, and is heavy and coarse and blunt and sweet and stupid as life itself.

Duchamp is known for calling a thing art, rather than making it. A lot of that is picked up in pop art, too.
