Sullivan is intended for the general reader as well as for the student. Its primary purpose is to present the elements of philosophy with simplicity and clarity in order to arouse that sense of wonder which Aristotle says is the beginning of the love of wisdom. 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.

    He became a teacher of grammar at Tagaste, and lived much under the influence of his mother and his friend Alypius. About 383 he went to Rome and soon after to Milan as a teacher of rhetoric, being now attracted by the philosophy of the Sceptics and of the Neo-Platonists. His studies of Paul's letters with Alypius and the preaching of Bishop Ambrose led in 386 to his rejection of all sensual habits and to his famous conversion from mixed beliefs to Christianity. He returned to Tagaste and there founded a religious community. In 395 or 396 he became Bishop of Hippo, and was henceforth engrossed with duties, writing and controversy. He died at Hippo during the successful siege by the Vandals.From Augustine's large output the Loeb Classical Library offers that great autobiography the Confessions (in two volumes); On the City of God (seven volumes), which unfolds God's action in the progress of the world's history, and propounds the superiority of Christian beliefs over pagan in adversity; and a selection of Letters which are important for the study of ecclesiastical history and Augustine's relations with other theologians.
