“Marcel Duchamp, “The Creative Act” statement : “Let us consider two important factors, the two poles of the creation of art: the artist on the one hand, and on the other the spectator who later becomes the posterity… 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. This becomes even more obvious when posterity gives a final verdict and sometimes rehabilitates forgotten artists.”
