"Obviously, three-dimensional work will not cleanly succeed painting and sculpture. It's not like a movement; anyway, movements no longer work; also, linear history has unraveled somewhat. The new work exceeds painting in plain power, but power isn't the only consideration, though the difference between it and expression can't be too great either. There are other ways than power and form in which one kind of art can be more or less than another." donald judd _ specific objects 1965
