All intervening steps, scribbles, sketches, drawings, failed work models, studies thoughts, conversations, are of interest. Those that show the thought process of the artist are sometimes more interesting than the final product

Formal art is essentially rational.

Irrational judgements lead to new experience.

Conceptual art became the liberating idea that gave the art of the next 40 years its real impetus.

When words such as painting and sculpture are used, they connote a whole tradition and imply a consequent acceptance of this tradition, thus placing limitations on the artist who would be reluctant to make art that goes beyond the limitations.

You shouldn't be a prisoner of your own ideas.

When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
