<DIV>Octavio Paz claims in this essential work that the two painters who had the greatest influence on the twentieth century were Pablo Picasso and Marcel Duchamp. If that conjunction surprises at first, Paz makes a convincing case with his analysis and by contrasting the two artists. ?I have linked their two names,” he writes, ?because it seems to me that each of them has in his own way succeeded in defining our age: the former by what he affirms; the latter by what he negates, by his explorations.” Considering Duchamp’s career and writings from his scandalous <I>Nude Descending a Staircase</I> in 1913 to his subsequent investigations, from his <I>Large Glass</I> and kinetic art to the Readymades and ?physiques amusantes” (?comic calculations”), Paz offers a highly personal assessment, exploring the apparent contradictions and seeming enigmas with the insight and lucidity that characterized all his writing.<br><BR>When this book was first published, <I>Publishers Weekly</I> called it an ?extraordinary and indispensable book” and said: ?Paz may have come closer to Duchamp’s essence as a philosopher of spiritual freedom than any critic to date.”<BR></DIV>
