The right angle is one of the world's basic shapes.

You can take an object and simply put anything you want in that object, and I accessed that partly through Freudian ideas.

I am for an art of things lost or thrown away. . . I am for an art that one smokes like a cigarette. . . I am for an art that flutters like a flag.

My work doesn't have the same rules as, say, Andy [Warhol]'s work. But it's gathered together for the simple reason that we all worked with the images and objects around us.

When you're working with an object, you can put in almost anything you want, you can make it abstract.

I'm always careful to say that I changed everything I found.

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