The creative act takes another aspect when the spectator experiences the phenomenon of transmutation: through the change from inert matter into a work of art, an actual transubtantiation has taken place, and the role of the spectator is to determine the weight of the work on the esthetic scale.
All in all, the creative act is not performed by the artist alone; the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualification and thus adds his contribution to the creative act.
Session on the Creative Act, Convention of the American Federation of Arts, Houston, Texas, April 1957. Participants: Pr Seitz, Pr Arnheim, Gregory Bateson, Marcel Duchamp
