The Heirs of Plato: A Study of the Old Academy, 347-274 B.C. (review)

When Plato died, in 347 BC, he left behind not only the collection of philosophical dialogues we still read with admiration, but also a remarkable organization, the "Academy," wherein his students continued the discussion he had initiated. Dillon's latest book is an attempt to recreate the intellectual climate in the Academy during the first generations after Plato's death, the "Old Academy," called thus to distinguish it from the "New Academy," which started with Arcesilaus in the mid 270's, who abandoned doctrinal speculations for a sceptical stance. Given the elusive nature of the dialogues, the interpretation of Plato's philosophy has been controversial from the beginning. Therefore, scholars always have been eager to know in which direction Plato's first successors—Speusippus, Xenocrates, Polemo—took the Academy; thus they hoped to find some justification for their own interpretation of Plato. Unfortunately, our information on the doctrines of Plato's first successors is scarce. Browsing through the fragments collected by scholars, one may be tempted to conclude that it is not such a great disaster that most texts of the Old Academy have been lost. For it seems that the Academy after Plato was leaning towards a rather esoteric metaphysical speculation about the first principles, which makes us lament on what has become of the philosophical heritage of Plato, a genius fallen into the hands of epigones. One gets the impression that the original and refreshing philosophical contributions came from outside the Academy, from the Lyceum founded by Aristotle and continued by Theophrastus, and later from Epicurus and Zeno and their new schools, which will dominate the Hellenistic period. This, however, is not the view of Dillon: "It will be the thesis of this book that Speusippus and Xenocrates set the agenda for what was to become, over the succeeding centuries, the intellectual tradition which we call Platonism" (v). Even early Stoicism is, in Dillon's view, a "development and formalization of contemporary Platonism" (235).

In an introductory chapter Dillon discusses the location and juridical structure of the Academy and gives a general survey of the main doctrines of the school. The following three chapters present the lives, work and thought of the first heads of the Academy; a final chapter is devoted to some minor members of the early Academy. The book concludes with a short epilogue on Arcesilaus and the reasons for his turn to scepticism. Dillon is an excellent writer who knows how to tease out and expound the most abstruse philosophical doctrines in a captivating way, mixing, as he does here, biographical anecdotes and witty comments with a sharp analysis of arguments and a speculative reconstruction of lost doctrines. I doubt, however, whether this book will become such a classic as his celebrated The Middle Platonists (Ithaca, 1977).

My first worry is anticipated by Dillon himself: "This is perforce a rather speculative book, and no doubt it will be criticized for that" (vii). Dillon defends himself against this critique: I have tried, he says, "to put the most favourable construction on the evidence available to us," his assumption being that the figures he is dealing with "were not philosophical imbeciles"(vii). My reservations are not about Dillon's attempt to construct a coherent doctrine using all relevant information on an author, but about his method of reconstruction, in particular his speculation and his preference for often questionable later material to fill the gaps in our information. "With a good deal of speculation, our exiguous information on Polemo's philosophical position can be fleshed out somewhat" (176). Thus, in his exposition of Speusippus's doctrine of the first principles, Dillon does not start from Aristotle, considering him too biased, but from chapter 4 of Iamblichus's treatise De communi mathematica scientia. In this Neo-Pythagorean treatise, Speusippus is not even mentioned. Even if there are arguments, as Dillon believes, to attribute the doctrine of Chapter 4 to Speusippus, one should...
