<P>Wide-ranging enough to encompass Buster Keaton, Charles Babbage, horses, and a man riding a bicycle while wearing a gas mask, <i>The Counterfeiters</i> is one of Hugh Kenner's greatest achievements. In this fascinating work of literary and cultural criticism, Kenner seeks the causes and outcomes of man's ability to simulate himself (a computer that can calculate quicker than we can) and his world (a mechanical duck that acts the same as a living one).</P><P>This intertangling of art and science, of man and machine, of machine and art is at the heart of this book. He argues that the belief in art as a uniquely human expression is complicated and questioned by the prevalence of simulations -- or "counterfeits" -- in our culture. Kenner, with his characteristically accessible style and wit, brings together history, literature, science, and art to locate the personal in what is an increasingly counterfeit world.</P>
