Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action.

This book is a collection of fourteen essays on the themes of selfhood and rationality in ancient Greek philosophy. The discussion ranges over seven centuries of innovative thought, starting with Heraclitus’ injunction to listen to the cosmic logos, and concluding with Plotinus’ criticism of those who make embodiment essential to human identity. For the Greek philosophers the notion of a rational self was bound up with questions about divinity and happiness called eudaimonia, meaning a god-favoured life or a life of likeness to the divine. While these questions are remote from current thought, Long also situates the book’s themes in modern discussions of the self and the self’s normative relation to other people and the world at large. Ideas and behaviour attributed to Socrates and developed by Plato are at the book’s centre. They are preceded by essays that explore general facets of the soul’s rationality. Later chapters bring in salient contributions made by Aristotle and Stoic philosophers. All but one of these pieces has been previously published in periodicals or conference volumes, but the author has revised and updated everything. The book is written in a style that makes it accessible to many kinds of reader, not only professors and graduate students but also anyone interested in the history of our identity as rational animals.

The philosophy of Epictetus, a freed slave in the Roman Empire, has been profoundly influential on Western thought: it offers not only stimulating ideas but practical guidance in living one's life. A. A. Long, a leading scholar of later ancient philosophy, gives the definitive presentation of the thought of Epictetus for a broad readership. Long's fresh and vivid translations of a selection of the best of Epictetus' discourses show that his ideas are as valuable and striking today as they were amost two thousand years ago. This is a book for anyone interested in what we can learn from ancient philosophy about how to live our lives.

For the past three decades A. A. Long has been at the forefront of research in Hellenistic philosophy. In this book he assembles a dozen articles on Stoicism previously published in journals and conference proceedings. The collection is biased in favour of Professor Long's more recent studies of Stoicism and is focused on three themes: the Stoics' interpretation of their intellectual tradition, their ethics and their psychology. The contents of the book reflect the peculiarly holistic and systematic features of Stoicism. The papers are printed here in their original form for the most part, but the author has made some minor corrections and stylistic or bibliographical changes. He has also added a postscript to three papers whose topics have been the subject of much discussion during the years since they first appeared.
