Abstract

The author, who received his doctorate from Syracuse University and is head of the department of philosophy at Western Kentucky University, offers in this study "an interpretation of Augustine's doctrine of illumination that is significantly different from the ones proposed by scholars who belong to the Thomist tradition." Before addressing himself to the doctrine of illumination, he devotes more than half of the book to an overview of Augustine's epistemology. In these preliminary chapters he discusses the structure of St. Augustine's theory of knowledge, and then Augustine's ideas on skepticism and truth, faith, sensation, and cogitation. The doctrine and texts covered in these chapters will be familiar to anyone who has devoted much time to the study of Augustine's thought. However, the author's treatment is noteworthy for its clear and succinct style. The sixth chapter broaches the question of man's knowledge of the rationes aeternae. Negatively, Augustine explicitly rejected some explanations of how man's mind can know the forms in the divine mind. Positively, "Augustine's theory of illumination includes at least three major points: God is light and illumines all men to different degrees; There are intelligible truths, the rationes aeternae, which God illumines; and the mind of man can know the divine truths only as God illumines him." The final two chapters are devoted to four interpretative theories of Augustine's notion of illumination. Three of these theories Dr. Nash rejects: that of St. Thomas which identifies the divine light and the agent intellect; the Franciscan theory which attributes the function of the agent intellect to God; the Formal approach, ascribed to Gilson and Copleston among others, which maintains that "the function of illumination... is not to give the human mind some definite content but simply to convey the quality of certainty and necessity to certain ideas." Arguing that all these theories are inadequate, the author then presents his own interpretation, a modified ontologism, which he feels provides a solution to the key paradoxes in Augustine's theory of illumination. Although one wishes that the author had discussed more fully man's knowledge of God, and although there may be need for a more careful scrutiny of Augustine's use of cogitatio, this book is to be recommended as a lucid discussion of a difficult subject. The index and notes are helpful, and the book well made.--H. F.
