The breadth and depth of the Platonic tradition, from Antiquity through to the early Middle Ages, is evidenced by the studies gathered in this volume, written by an international team of contributors in honour of John Dillon. The first papers, on Plato, include a discussion of the problem of evil and of the theme of love n the Symposium. There follows a section of the Middle-Platonists, dealing with how this tradition adapted and developed themes such as the world-soul as a mirror and the notion of an intellible cosmos. Five papers then focus on aspects of the thought of Plotinus, and a final group covers the later Neoplatonic tradition, from Augustine to John Scotus Eriugena, including a survey by the late Henry Blumenthal on perception and memory.
