40. Marcel Duchamp French born artist and theorist) 1887 - 1968 "If it's not shocking, it's not worth doing..." The Creative Act: "Let's consider two important factors, the two poles of the creation of art: the artist on one hand, and on the other, the spectator who later becomes the posterity." "...it's the posthumous spectator, because the contemporary spectator is worthless, in my opinion. His is of minimum value compared to that of posterity, which, for example, allows some things to stay in the Lourve."
