"A sophisticated and illuminating study of central questions about Aristotle's views on practical reason and the ultimate good. Cooper's three chapters . . . examine familiar exegetical puzzles in a fresh and challenging way; but they also . . . raise new and fruitful questions about the philosophical merits and implications of Aristotle's theories. . . . He writes vigorously and lucidly, with both scholarly rigor and philosophical imagination." --T. H. Irwin in Archiv fur Geschichte der Philosophie
