Ever since its rediscovery in the thirteenth century, Aristotle's Nicomachean Ethics has figured as a prime model of philosophical ethics in Western moral thought. This collection of articles for the first time surveys the medieval tradition of commentaries on the work from its origins to the fifteenth century. The twelve articles concentrate on the moral and intellectual virtues around which Aristotle's ethic revolves and in many cases compare the discussion of the virtues in the medieval commentaries with contemporary theological debate. Taken together, the articles show the diverse and surprisingly creative ways in which medieval intellectuals during three centuries combined widely diverging currents of ancient and Christian moral thought in order to formulate a philosophical ethic suitable to their times.
