"The topic is significant, especially now in view of the renewed interest in scientific cosmology and its relation to religion, but it is also of great importance for the history of medieval Jewish, Christian, and Islamic philosophy. The book covers a wide range of difficult, often technical philosophical ideas and theories in a highly analytical and systematic fashion, and I especially like the author's consistent ability to sketch out the arguments of these thinkers in a careful and lucid way. She also displays considerable erudition in both original sources and scholarly literature, regardless of whether the discussions are historical or philosophical. I found the book interesting and illuminating." — Barry S. Kogan, author of Averroes and the Metaphysics of Causation
