This well-structured overview begins with an historical study of philosophy, tracing the evolution of philosophical problems from their simplest origins, and continues with an analysis of the more concrete problems about man himself. The more abstract problems of man and his relation to the world around him make up the final study of this book.

Sullivan works in the great classical, realist tradition of Plato, Aristotle, Augustine, Aquinas and their modern-day inheritors–exposing the perennially valid and vital principles of philosophy and emphasizing the profound moral and social implications of these principles. He respects the distinction between natural and revealed wisdom, but does not hesitate to point out how the conclusions of philosophy are complemented by the truths of revelation.

An Introduction to Philosophy clearly demonstrates that philosophy is a good deal more than a classroom exercise.
