To all appearances the artist acts like a mediumistic being who, from the labyrinth beyond time and space, seeks his way out to a clearing. If we give the attributes of a medium to the artist, we must then deny him the state of consciousness on the aesthetic plane about what he is doing or why he is doing it. All this decisions in the artistic execution of the work rest with pure intuition and cannot be translated into a self-analysis, spoken or written, or even thought out.
Marcel DuchampYou know exactly what I think of photography. I would like to see it make people despise painting until something else will make photography unbearable. (In a letter to Alfred Stieglitz)
