J. L. Ackrill's work on Plato and Aristotle has had a considerable influence upon ancient philosophical studies in the late twentieth century. In his writings the rigour and clarity of contemporary analytical philosophy are brought to bear upon ancient thought; in many cases he has provided the first analytic treatment of a key issue. Gathered now in this volume are the best of Ackrill's essays on the two greatest philosophers of antiquity. Here he examines a wide range of texts and topics -- from ethics and logic to epistemology and metaphysics -- which continue to be the focus of debate today.

J. L. Ackrill is Emeritus Professor of History of Philosophy in the University of Oxford, and an Emeritus Fellow of Brasenose College.
