The thinking of John Cage derived from Duchamp and Dada. I was not interested in that.
Unless you're involved with thinking about what you're doing, you end up doing the same thing over and over, and that becomes tedious and, in the end, defeating.
I was not interested in irony; I wanted to emphasize the primacy of the idea in making art.
When artists make art, they shouldn't question whether it is permissible to do one thing or another.
Also, since art is a vehicle for the transmission of ideas through form, the reproduction of the form only reinforces the concept. It is the idea that is being reproduced. Anyone who understands the work of art owns it. We all own the Mona Lisa.
Minimalism wasn't a real idea - it ended before it started.
