Agonistes comprises a collection of essays presented by his friends and colleagues to Denis O'Brien, former Directeur de recherche at the Centre Nationale de Recherche Scientifique, representing the full range of his scholarly interests in the field of ancient philosophy, from the Presocratics, through Plato, Aristotle and Hellenistic philosophy, to Plotinus and later Neoplatonism. The honorand himself leads off with a stimulating Apologia, sketching the development of his scholarly interests and dwelling on the issues that have chiefly concerned him. The contributions then follow in...

50 years before Philoponus, two Christians from Gaza, seeking to influence Alexandrian Christians, defended the Christian belief in resurrection and the finite duration of the world, and attacked rival Neoplatonist views. Aeneas addresses an unusual version of the food chain argument against resurrection, that our bodies will get eaten by other creatures. Zacharias attacks the Platonist examples of synchronous creation, which were the production of light, of shadow, and of a footprint in the sand. A fragment survives of a third Gazan contribution by Procopius. Zacharias lampoons the...

It was the Sophists who understood the art of rhetoric and the importance of transforming effective reasoning into persuasive public speaking. Their enquiries - into the status of women, slavery, the distinction between Greeks and barbarians, the existence of the gods, the origins of religion, and whether virtue can be taught - laid the groundwork for the insights of the next generation of thinkers such...

John Dillon presents the first English translation of Alcinous's Handbook of Platonism, accompanied by an introduction and a philosophical commentary that reveal the intellectual background to the ideas in the work.

Dexippus, a pupil or follower of lamblichus, preserves a crucial moment in the Neoplatonist interpretation of Aristotle. Aristotle's Categories has been attacked by Plotinus, but Porphyry's defence proved decisive, so that the Categories was acceptable as compatible with Platonism and an essential introduction to the Neoplatonist curriculum.
Porphyry's main commentary on the Categories, however, containing the vital defence, is lost, as is that of his pupil lamblichus. The ideas of these two principal Neoplatonists can be reconstructed, in part, from Dexippus.
