Irrational judgements lead to new experience.
Buying books was a way anyone could acquire a work of art for very little.
The idea becomes a machine that makes the art.
I believe that the artist's involvement in the capitalist structure is disadvantageous to the artist and forces him to produce objects in order to live.
Conceptual art is only good if the idea is good.
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.
