In this classic work, the eminent Catholic philosopher Étienne Gilson deals with one of the most important and perplexing metaphysical problems: the relation between our notion of God and demonstrations of his existence. Gilson examines Greek, Christian, and modern philosophy as well as the thinking that has grown out of our age of science in this fundamental analysis of the problem of God.

"[I] commend to another generation of seekers and students this deeply earnest and yet wistfully gentle little essay on the most important (and often, at least nowadays, the most neglected) of all metaphysical--and existential--questions. . . . The historical sweep is breathtaking, the one-liners arresting, and the style, both intellectual and literary, altogether engaging." --Jaroslav Pelikan, from the foreword

"We have come to expect from the pen of M. Gilson not only an accurate exposition of the thought of the great philosophers, ancient and modern, but what is of much more importance and of greater interest, a keen and sympathetic insight into the reasons for that thought. The present volume does not fail to fulfill our expectations. It should be read by every Christian thinker." --Ralph O. Dates, America
