Marcel Duchamp, “The Creative Act” (1957)
In the creative act, the artist goes from intention to realization through a chain of totally subjective reactions. His struggle toward the realization is a series of efforts, pains, satisfaction, refusals, decisions, which also cannot and must not be fully self-conscious, at least on the esthetic plane.
The result of this struggle is a difference between the intention and its realization, a difference which the artist is not aware of.
Consequently, in the chain of reactions accompanying the creative act, a link is missing. This gap, representing the inability of the artist to express fully his intention, this difference between what he intended to realize and did realize, is the personal ‘art coefficient’ contained in the work.
In other words, the personal ‘art coefficient’ is like a arithmetical relation between the unexpressed but intended and the unintentionally expressed.
What art is in reality is this missing link [between intention and realization], not the links which exist. It’s not what you see that is art, art is the gap. I like this idea and even if it’s not true, I accept it for the truth.
