"Aristotle versus Plato. For a long time that is the angle from which the tale has been told, in textbooks on the history of philosophy and to university students. Aristotle's philosophy, so the story goes, was au fond in opposition to Plato's. But it was not always thus."—from the Introduction In a wide-ranging book likely to cause controversy, Lloyd P. Gerson sets out the case for the "harmony" of Platonism and Aristotelianism, the standard view in late antiquity. He aims to show that the twentieth-century view that Aristotle started out as a Platonist and ended up as an anti-Platonist is seriously flawed. Gerson examines the Neoplatonic commentators on Aristotle based on their principle of harmony. In considering ancient studies of Aristotle's Categories, Physics, De Anima, Metaphysics, and Nicomachean Ethics, the author shows how the principle of harmony allows us to understand numerous texts that otherwise appear intractable. Gerson also explains how these "esoteric" treatises can be seen not to conflict with the early "exoteric" and admittedly Platonic dialogues of Aristotle. Aristotle and Other Platonists concludes with an assessment of some of the philosophical results of acknowledging harmony.

George Karamanolis breaks new ground in the study of later ancient philosophy by examining the interplay of the two main schools of thought, Platonism and Aristotelianism, from the first century BC to the third century AD. Arguing against prevailing scholarly assumption, he argues that the Platonists turned to Aristotle only in order to elucidate Plato's doctrines and to reconstruct Plato's philosophy, and that they did not hesitate to criticize Aristotle when judging him to be at odds with Plato. Karamanolis offers much food for thought to ancient philosophers and classicists.

Was Plato a Platonist? While ancient disciples of Plato would have answered this question in the affirmative, modern scholars have generally denied that Plato’s own philosophy was in substantial agreement with that of the Platonists of succeeding centuries. In From Plato to Platonism, Lloyd P. Gerson argues that the ancients were correct in their assessment. He arrives at this conclusion in an especially ingenious manner, challenging fundamental assumptions about how Plato’s teachings have come to be understood. Through deft readings of the philosophical principles found in Plato's dialogues and in the Platonic tradition beginning with Aristotle, he shows that Platonism, broadly conceived, is the polar opposite of naturalism and that the history of philosophy from Plato until the seventeenth century was the history of various efforts to find the most consistent and complete version of "anti-naturalism."Gerson contends that the philosophical position of Plato—Plato’s own Platonism, so to speak—was produced out of a matrix he calls "Ur-Platonism." According to Gerson, Ur-Platonism is the conjunction of five "antis" that in total arrive at anti-naturalism: anti-nominalism, anti-mechanism, anti-materialism, anti-relativism, and anti-skepticism. Plato’s Platonism is an attempt to construct the most consistent and defensible positive system uniting the five "antis." It is also the system that all later Platonists throughout Antiquity attributed to Plato when countering attacks from critics including Peripatetics, Stoics, and Sceptics. In conclusion, Gerson shows that Late Antique philosophers such as Proclus were right in regarding Plotinus as "the great exegete of the Platonic revelation."

'Middle' Platonism has some claim to be the single most influential philosophical movement of the last two thousand years, as the common background to 'Neoplatonism' and the early development of Christian theology. This book breaks with the tradition of considering it primarily in terms of its sources, instead putting its contemporary philosophical engagements front and centre to reconstruct its philosophical motivations and activity across the full range of its interests. The volume explores the ideas at the heart of Platonist philosophy in this period and includes a comprehensive selection of primary sources, a significant number of which appear in English translation for the first time, along with dedicated guides to the questions that have been, and might be, asked about the movement. The result is a tool intended to help bring the study of Middle Platonism into mainstream discussions of ancient philosophy.

The Seventh Platonic Letter describes Plato's attempts to turn the ruler of Sicily, Dionysius II, into a philosopher ruler along the lines of the Republic. It explains why Plato turned from politics to philosophy in his youth and how he then tried to apply his ideas to actual politics later on. It also sets out his views about language, writing and philosophy. As such, it represents a potentially crucial source of information about Plato, who tells us almost nothing about himself in his dialogues. But is it genuine? Scholars have debated the issue for centuries, although recent opinion has moved in its favour. The origin of this book was a seminar given in Oxford in 2001 by Myles Burnyeat and Michael Frede, two of the most eminent scholars of ancient philosophy in recent decades. Michael Frede begins by casting doubt on the Letter by looking at it from the general perspective of letter writing in antiquity, when it was quite normal to fabricate letters by famous figures from the past. Both then attack the authenticity of the letter head-on by showing how its philosophical content conflicts with what we find in the Platonic dialogues. They also reflect on the question of why the Letter was written, whether as an attempt to exculpate Plato from the charge of meddling in politics (Frede), or as an attempt to portray, through literary means, the ways in which human weakness and emotions can lead to disasters in political life (Burnyeat).

In this volume, the relationships between two of the most vital currents in Western thought are examined by a group of nineteen internationally known specialists in a variety of disciplines—classics, patristics, philosophy, theology, history of ideas, and literature. The contributing scholars discuss Neoplatonic theories about God, creation, man, and salvation, in relation to the ways in which they were adopted, adapted, or rejected by major Christian thinkers of five periods: Patristic, Later Greek and Byzantine, Medieval, Renaissance, and Modern. Contributors include G.-H. Allard, A. Hilary Armstrong, Elizabeth Bieman, Linos Benakis, Henry Blumenthal, Mary T. Clark, Norris Clarke, John Dillon, Cornelio Fabro, John N. Findlay, Maurice de Gandillac, Edward P. Mahoney, Bernard McGinn, Dominic J. O'Meara, John J. O'Meara, Jean Pépin, Mary Carman Rose, Henri-Dominique Saffrey, Charles B. Schmitt, and Gérard Verbeke.
