Francis Sparshott has written a wonderfully wise, urbane, honest, insightful, and provocative commentary on Aristotle's chief ethical work, the Nicomachean Ethics (NE). Some commentaries on ancient philosophical texts are line-by-line struggles to nail down the meaning of the text, as if the commentator were roofing a house in a high wind, one shingle at a time. Other commentaries are collections of essays, each inspired by a passage in the text, but each growing into a relatively self-contained discussion. Sparshott's commentary is neither of these things.
