This lecture was designed as an introduction to Plato's theory of Forms. Reference is made to key passages of Plato's dialogues, but no guidance on further reading is offered, and numerous controversies about the theory's interpretation are left in the background. An initial sketch of the theory's origins in the inquiries of Plato's teacher Socrates is followed by an explanation of the Forms’ primary characteristic, Plato's metaphysical separation of them from the sensible world. Other aspects discussed include the Forms’ metaphysical relation to sensible particulars, their ‘self-predication’, and the range of items that have Forms. Finally, the envisaged structure of the world of Forms is illustrated by a look at Plato's famous Cave simile.

This paper is a critical re-examination of the argument in Plato's "Phaedo" for the thesis that all learning is recollection of prenatal knowledge. Plato's speaker Socrates concentrates on the case of 'equal sticks and stones', viewed as striving without complete success to resemble a Form, the Equal itself. The paper argues that (a) this is a rather special case, focused on geometry; (b) Plato is at pains to emphasize that the Form-particular relation need not be one of resemblance at all, a concession which he insists would not, if made, damage his theory of recollection; (c) even if resemblance is assumed to be the correct account of that relationship, the 'striving to be like' gloss is not an integral component of Plato's metaphysics.

Plato's Cratylus is a brilliant but enigmatic dialogue. It bears on a topic, the relation of language to knowledge, which has never ceased to be of central philosophical importance, but tackles it in ways which at times look alien to us. In this reappraisal of the dialogue, Professor Sedley argues that the etymologies which take up well over half of it are not an embarrassing lapse or semi-private joke on Plato's part. On the contrary, if taken seriously as they should be, they are the key to understanding both the dialogue itself and Plato's linguistic philosophy more broadly. The book's main argument is so formulated as to be intelligible to readers with no knowledge of Greek, and will have a significant impact both on the study of Plato and on the history of linguistic thought.

In Empedocles’ zoogony, an original set of single-specialism organisms – solitary hands, eyes, etc. – combined into complex organisms, of which the fittest survived. A less recognized anticipation of (one strand of) the Darwinian tradition relates to the superorganism theory: what is naturally selected for is not the individual and/or its kin, but, as most manifestly in insect colonies, the cooperative group. Empedocles’ Love likewise works by promoting co-operation, whose emergence in complex organisms reflects her growing power, and the periodic world-organism, Sphairos, her ultimate triumph. This latter divinity is not a homogeneous blend of the elements, but a single self-sufficient superorganism.

Oxford Studies in Ancient Philosophy is a volume of original articles on all aspects of ancient philosophy. The articles may be of substantial length, and include critical notices of major books. From 2000 OSAP is being published not once but twice yearly, to keep up with the abundance of good material submitted; and it is being made available in paperback as well as hardback, in response to demand from scholars wishing to purchase it. This volume, the second of 2000, features contributors from Michael Wedin and Dominic Scott, and discusses issues ranging from Socratic Intellectualism to Aristotle on animal psychology. 'standard reading among specialists in ancient philosophy' Brad Inwood, Bryn Mawr Classical Review.

Le chapitre 4 du premier livre des Mémorables de Xénophon était quasiment un texte canonique pour la théologie des premiers stoïciens : il contient la première version de « la preuve par la providence » (the Argument from Design) et constitue un témoignage capital et négligé concernant la théologie de Socrate. Les idées qui y sont exposées ne dérivent en effet pas de Diogène d'Apollonie, dont le rôle dans l'histoire de la pensée téléologique a été largement surestimé. Je défends la thèse que le texte du Contre les savants IX, 88-110 de Sextus Empiricus constitue un témoignage unique qui permet de comprendre comment les premiers stoïciens se sont efforcés d'extraire une preuve rigoureuse de l'existence de dieu du chapitre de Xénophon ainsi que du Timée de Platon (29b-30b), et comment ils ont ensuite corrigé leurs syllogismes pour les soustraire aux réfutations parodiques (parabolai) d'Alexinus. On peut ainsi observer la manière dont les stoïciens ont forgé leurs armes théologiques à partir de la tradition dont ils prétendaient être les héritiers.
