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

Usually when someone says a thing is too simple they're saying that certain familiar things aren't there, and they're seeing a couple maybe that are left... But actually there may be... several new things to which they aren't paying attention. These may be quite complex... They may [also] be read all at once. This is important to most of the best work going on now. It has to have a wholeness to it that previous work didn't have, but still, within that, it's not all as simple as [people] say.

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.

The main qualifications to the lesser position of painting is that advances in art are certainly not always formal ones.
