You don''t have to agree with all of Thierry de Duve''s premises and arguments (needless to say I don''t) in order to recognize that he has written a remarkable book. The essays gathered in Kant After Duchamp mount the most formidable case yet made for Duchamp''s importance, and what makes de Duve''s achievement all the more unexpected is that this is done by way of an intense engagement with the writings of Duchamp''s seeming opposite, the critic Clement Greenberg. A third constant presence in these pages is Kant''s Critique of Judgement, which at once governs de Duve''s understanding of Greenberg''s ''formalism'' and is itself brilliantly reinterpreted in the light of Duchamp''s readymades. De Duve has always been an independent thinker. Now he has produced an indispensable book, a brilliant and learned ''archaeology'' of Duchampian modernism that is also a highly original contribution to philosophical aesthetics.
