Society is basically not interested in art. Art has a purpose of its own. - Donald Judd

I am not interested in the kind of expression that you have when you paint a painting with brush strokes. It's all right, but it's already done and I want to do something new. I didn't want to get into something which is played out and narrow. I want to do as I like, invent my own interests. Of course, that doesn't mean that people who, like Newman, still paint are worn out. But I think that's a particular kind of experience involving a certain immediacy between you and the canvass, you and the particular kind of experience of that particular moment. I think what I'm trying to deal with is something more long range than that in a way, more obscure perhaps, more involved with things that happen over a longer time perhaps. At least it's another area of experience.

Eighteen years ago someone asked me to design a coffee table. I thought that a work of mine which was essentially a rectangular volume with the upper surface recessed could be altered. This debased the work and produced a bad table which I later threw away. The configuration and the scale of art cannot be transposed into furniture and architecture. The intent of art is different from that of the latter, which must be functional. If a chair or a building is not functional, if it appears to be only art, it is ridiculous... A work of art exists as itself; a chair exists as a chair itself.

Material, space, and color are the main aspects of visual art. Everyone knows that there is material that can be picked up and sold, but no one sees space and color. Two of the main aspects of art are invisible; the basic nature of art is invisible.
