“Like Leonardo, Duchamp had always been more interested in the process of structuring a work of art than in the final execution and ultimate result. Chess seemed to make possible a constant renewal of this process, involving a combination of mathematics and space, logic and imagination, in which the end result is zero in the sense that the board is swept clean. Thus, as a form of mathematic-esthetic speculation, chess playing recapitulated Duchamp’s renunciation of painting and summarized the Dada belief that the value of creative activity lies in the process, in the act of making, rather than in the esthetic significance of the thing made.”
