Abstract
This book is an essay in systematic metaphysics. Its ambitious aim is to present an a posteriori causal proof for the existence of God. In addition to its metaphysical assault on the problem of proving God's existence, it contains forays into epistemology, philosophy of language, philosophy of logic and philosophy of science. As a result, the book is a rich and complex tapestry of argumentation that well illustrates its author's contention that philosophy is a "seamless web". Braine has evidently been influenced by Gilson's interpretation of Aquinas. But though his argument bears a family resemblance to Aquinas's Prime Mover Argument, it is a distinct and original philosophical construction.
