0This book collects essays published in journals including Commentary, The Weekly Standard, and elsewhere. It centers on three profound mysteries: the existence of the human mind; the existence and diversity of living creatures; and the existence of matter. How they did they come into being? The author, Dr. David Berlinski, is a senior fellow at the Discovery Institute and formerly a fellow at the Institut des Hautes Etudes Scientifiques in France. His other books include The Devil's Delusion: Atheism and Its Scientific Pretensions, Newton's Gift, and A Tour of the Calculus.
