There is much to celebrate in this important new book by one of the finest moral theologians writing today. Gilbert Meilaender of Valparaiso University gives us a fine example of “thinking with Augustine” about such crucial topics as desire, duty, sex and grief. A chapter on each engages the scholarly literature without getting bogged down in it. The book’s final word on method laments academia’s obsession with methodological questions and suggests that we dive right into the big ones. This ex post facto explanation shows the glory of the book: Meilaender wants to make strong arguments about the morally weighty questions that vex our lives. I often take the opposite interpretive fork in the road from the one Meilaender chooses, but wrestling with him is always salutary, and his method deserves wide emulation.
