Moreau sketches here with enthusiasm the large features of Aquinas’s epistemology. He is not, as he makes clear, a Thomist either by training or by avowal. The book is not, then, a specialist’s monograph or dogmatic treatise. It is Moreau’s attempt to hear what Aquinas will say to the great questions. The attempt is largely successful in attending to Aquinas’s remarks, though it does not catch their ambiguities.
