In that book, I explored the idea, virtually ubiquitous in late antiquity, that Aris- totle’s philosophy was in “harmony” with Platonism. Although I did try to explicate the harmonists’ account of the nature of Platonism, I had little to say about whether that account was accurate. In short, I largely sidestepped the tendentious question “Was Plato a Platonist?” The present work is an attempt to answer that question, or at the very least to show that an affi rma- tive answer is not nearly as implausible as it is often taken to be. In search- ing for an approach to my question that is minimally non-question-begging, I have been led to reconsider a number of modern assumptions regarding the Platonic dialogues and their relation to Platonism, the relation between Platonism and a putative Socratic philosophy, and the direct and indirect testimony of ancient philosophers regarding Platonism, in particular that of Aristotle. The fi rst part of the book is taken up mainly with the critical ex- amination of these assumptions. In part 2, I examine the “construction” of various versions of Platonism in the Old Academy, and among the ‘Middle’ Platonists. In these chapters, I face the problem of why, indeed, there are different versions of Platonism if Plato’s disciples were in fact aiming to be faithful to the teachings of the master. For anyone inclined to the affi rma- tive answer to my main question, this problem cannot be avoided. As Sextus Empiricus said of dogmatists in general, their disagreement among them- selves is one of the best possible arguments for skepticism. So, too, if Platon- ists disagree, does this not at least suggest that with regard to the question of whether Plato was a Platonist, there is in fact no truth of the matter? There is a considerable literature that takes the dialogues as ink blots for Download Date | 6/27/17 8:27 AM x Preface a philosophical Rorschach test. And it cannot be denied that among some self-described followers of Plato, contradictory views about certain matters are held. Nevertheless, I aim to show that behind such disagreements as ex- isted there was a profound agreement about fi rst principles and that assent to the elements of that agreement is what Platonism was always thought to be. In part 3, I try to show that in Plotinus we have, as Proclus insisted, the most authentic and insightful “exegete of the Platonic revelation.” This is true, I argue, both in his construction of the Platonic system and in his dem- onstration of how that system is the ultimate basis for many of the solutions that Plato gives to the philosophical problems he raises. The tenor of this work undoubtedly amounts to swimming against some currents of contemporary scholarship, although probably not as much as it would have a generation ago. It amounts to challenging some orthodox- ies of Platonic interpretation, especially as these are still found in North America. And it amounts to a willingness to explore a hypothesis according to which ‘Platonism’ is the name of a well-articulated philosophical posi- tion and not just the label for the “sum total” of Plato’s literary product. As much as this book is explicitly rooted in the minutiae of the history of ancient philosophy, its constant overarching goal is to bring history and philosophy into fruitful collaboration.
