"Great philosophers as well as great artists have the gift of inspiring profoundly different conceptions and meaning in the individuals who contemplate their work," writes Joseph Owens. Even now, twenty-three centuries after the philosopher's death, the study of Aristotle continues to challenge us and to broaden our intellectual outlook. In this volume, John R. Catan has gathered together 18 major essays by the well-known aristotelian scholar Joseph Owens that have influenced current opinion on the philosopher. The collection represents the first well-rounded picture of Owens's interpretation of the theory of knowledge and associated cognitive problems in moral philosophy. Among the themes highlighted are: universality, cognition, matter and predication, the sciences, the soul, and nature. Included is a complete Owens bibliography, covering the years from 1946 to the present.
