"Any combining, mixing, adding, diluting, exploiting, vulgarizing, or popularizing of abstract art deprives art of its essence and depraves the artist's artistic consciousness. Art is free, but it is not a free-for-all. The one struggle in art is the struggle of artists against artists, of artist against artist, of the artist-as-artist within and against the artist-as- man, -animal, or -vegetable. Artists who claim their artwork comes from nature, life, reality, earth or heaven, as 'mirrors of the soul' or 'reflections of conditions' or 'instruments of the universe', who cook up 'new images of man' - figures and 'nature-in-abstraction' - pictures, are subjectively and objectively, rascals or rustics."

“The art of a chair is not its resemblance to art, but is partly its reasonableness, usefulness and scale as a chair. These are proportion, which is visible reasonableness. The art in art is partly the assertion of someone's interest regardless of other considerations. A work of art exists as itself; a chair exists as a chair itself. And the idea of a chair isn't a chair.”

“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.”

“Everything sculpture has, my work doesn’t.”

“Since I leapt into the world an empiricist, ideality was not a quality I wanted.”

“I'm not arguing, incidentally, for a confusion of art and architecture, a fashion now, but for a coherent relationship. Therefore, within the capacity of one person or of a small group, the relationship of all visible things should be considered.”

“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.”
