“ In a sense, Joyce was Beckett's Don Quixote, and Beckett was his Sancho Panza. Joyce aspired to the One; Beckett encapsulated the fragmented many. But as each author accomplished his task, it was in the service of the other. Ultimately, Beckett's landscapes would resound with articulate silence, and his empty spaces would collect within themselves the richness of multiple shadows--a physicist would say the negative particles--of all that exists in absence, as in the white patches of an Abstract Expressionist painting. Becket would evoke, on his canvasses of vast innuendo and through the interstices of conscious and unconscious thought, the richness that Joyce had made explicit in words and intricate structure. ”
