Lloyd P. Gerson

A total philosophy of life, death, religion, ethics, and culture promising liberation from the obstacles that stand in the way of our happiness, the teachings of Epicurus claimed many thousand committed followers over the ancient Mediterranean world. This title fills the need for a reliable selection and translation of the main surviving evidence.

Plato's moral realism rests on the Idea of the Good, the unhypothetical first principle of all. It is this, as Plato says, that makes just things useful and beneficial. That Plato makes the first principle of all the Idea of the Good sets his approach apart from that of virtually every other philosopher. This fact has been occluded by later Christian Platonists who tried to identify the Good with the God of scripture. But for Plato, theology, though important, is subordinate to metaphysics. For this reason, ethics is independent of theology and attached to metaphysics. This book challenges many contemporary accounts of Plato's ethics that start with the so-called Socratic paradoxes and attempt to construct a psychology of action or moral psychology that makes these paradoxes defensible. Rather, Lloyd Gerson argues that Plato at least never thought that moral realism was defensible outside of a metaphysical framework.

In his third and concluding volume, Lloyd P. Gerson presents an innovative account of Platonism, the central tradition in the history of philosophy, in conjunction with Naturalism, the "anti-Platonism" in antiquity and contemporary philosophy. Gerson contends that Platonism identifies philosophy with a distinct subject matter, namely, the intelligible world and seeks to show that the Naturalist rejection of Platonism entails the elimination of a distinct subject matter for philosophy. Thus, the possibility of philosophy depends on the truth of Platonism. From Aristotle to Plotinus to Proclus, Gerson clearly links the construction of the Platonic system well beyond simply Plato's dialogues, providing strong evidence of the vast impact of Platonism on philosophy throughout history. Platonism and Naturalism concludes that attempts to seek a rapprochement between Platonism and Naturalism are unstable and likely indefensible.

"Gerson's book is a highly valuable, well-written contribution to Platonism research. It persuasively makes a case for understanding Plato's philosophy as a coherent system that has an intricate and meaningful relation to later Platonistic philosophical positions. From this point, Plato appears as a Platonist indeed." — Claas Lattman - CLASSICAL JOURNAL 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 are 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."

De Providentia . The selections from Plotinus have also been expanded.

This concise anthology of primary sources designed for use in an ancient philosophy survey ranges from the Presocratics to Plato, Aristotle, the Hellenistic philosophers, and the Neoplatonists. The Second Edition features an amplified selection of Presocratic fragments in newly revised translations by Richard D. McKirahan. Also included is an expansion of the Hellenistic unit, featuring new selections from Lucretius and Sextus Empiricus as well as a new translation, by Peter J. Anderson, of most of Seneca's De Providentia . The selections from Plotinus have also been expanded.

This is the first title in the Key Themes in Ancient Philosophy series, which provides concise books, written by major scholars and accessible to non-specialists, on important themes in ancient philosophy which remain of philosophical interest today. In this book, Professor Gerson explores ancient accounts of the nature of knowledge and belief from the Presocratics up to the Platonists of late antiquity. He argues that ancient philosophers generally held a naturalistic view of knowledge as well as of belief. Hence, knowledge was not viewed as a stipulated or semantically determined type of belief but was rather a real or objectively determinable achievement. In fact, its attainment was identical with the highest possible cognitive achievement, namely wisdom. It was this naturalistic view of knowledge at which the ancient Skeptics took aim. The book concludes by comparing the ancient naturalistic epistemology with some contemporary versions.

"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.

Knowing Persons is an original study of Plato's account of personhood. For Plato, embodied persons are images of a disembodied ideal. The ideal person is a knower. Hence, the lives of embodied persons need to be understood according to Plato's metaphysics of imagery. For Gerson, Plato's account of embodied personhood is not accurately conflated with Cartesian dualism. Plato's dualism is more appropriately seen in the contrast between the ideal disembodied person and the embodied one than in the contrast between mind or soul and body. This study argues that Plato's analysis of personhood is intended to cohere with his two-world metaphysics as well as a radical separation of knowledge and belief. Gerson demonstrates that Plato's account of persons plays a key role not just in his theory of mind, but in his theory of knowledge, his metaphysics, and his ethics. A proper understanding of Plato's account of persons must therefore place it in the context of his doctrines in these areas. Knowing Persons fills a significant gap by showing the way to such an understanding.

First published in 1999. We are fortunate in possessing a fascinating document, The Life of Plotinus, written by the philosopher Porphyry, a pupil and associate of Plotinus for the last eight years of his life. The basic facts contained in this Life can be quickly recounted. Plotinus was likely a Greek born in Egypt in AD 205. It is possible, though, that he came from a Hellenized Egyptian or Roman family. In his 28th year, Plotinus discovered in himself a thirst for philosophy. This is a collection of his works- Ennead I contains treatises on what Porphyry calls “ethical matters”; Enneads II–III contain treatises on natural philosophy or cosmology, with some rationalizations for the inclusion of III. 4, 5, 7, and 8. Ennead IV concerns the soul; V Intellect or and VI being, numbers, and the One. The thematic unity of Enneads I, IV, and V is somewhat greater than the rest.
