Method and Metaphysics presents twenty-six essays in ancient philosophy by Jonathan Barnes, one of the most admired and influential scholars of his generation. The essays span four decades of his career, and are drawn from a wide variety of sources: many of them will be relatively unknown even to specialists in ancient philosophy. Several essays are now translated from the original French and made available in English for the first time; others have been substantially revised for republication. The volume opens with eight essays about the interpretation of ancient philosophical texts, and about the relationship between philosophy and its history. The next five essays examine the methods of ancient philosophers. The third section comprises thirteen essays about metaphysical topics, from the Presocratics to the late Platonists. This collection will be a rich feast for students and scholars of ancient philosophy.
