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."

Given the conception of philosophy held by continental thinkers, and in particular their greater sensitivity to the kinship of philosophy and literature, Drew A. Hyland argues that they should be much more attentive to the literary dimension of Plato's thinking than they have been. He believes they would find in the dialogues not the various forms of "Platonism" that they wish to reject, but instead a thinking much more congenial and challenging to their own predilections. By carefully examining the works of Heidegger, Derrida, Irigaray, and Cavarero, Hyland points to the tendency of continental thinkers to view Plato's dialogues through the lens of Platonism, thus finding Platonic metaphysics, Platonic ethics, and Platonic epistemology, while overlooking the literary dimension of the dialogues, and failing to recognize the extent to which the form undercuts anything like the Platonism they find. The striking exception, Hyland claims, is Hans-Georg Gadamer who also demonstrates the compatibility of the Platonic dialogues with the directions of continental thinking.

The present volume argues that Plato and Platonism should be understood not as a series of determinate doctrines or philosophical facts to be pinned down once and for all, but rather as an inexhaustible mine of possible trajectories. The book examines in this light different strands of Platonic thinking from the dialogues themselves through later Antiquity and the Medieval World into Modernity and Post-Modernity with new essays ranging from Descartes, Kant, Hegel, and Natorp to Yeats, Levinas and Derrida. And also suggests the possibility of reading the dialogues and the whole tradition resonating in and through them in new, unexpected ways.

In this insightful new book David J. Yount argues, against received wisdom, that there are no essential differences between the metaphysics of Plato and Plotinus. Yount covers the core principles of Plotinian thought: The One or Good, Intellect, and All-Soul (the Three Hypostases), Beauty, God(s), Forms, Emanation, Matter, and Evil. After addressing the interpretive issues that surround the authenticity of Plato's works, Plotinus: The Platonist deftly argues against the commonly held view that Plotinus is best interpreted as a Neo-Platonist, proposing he should be thought of as a Platonist proper. Yount presents thorough explanations and quotations from the works of each classical philosopher to demonstrate his thesis, concluding comprehensively that Plato and Plotinus do not essentially differ on their metaphysical conceptions. This is an ideal text for Plato and Plotinus scholars and academics, and excellent supplementary reading for upper-level undergraduates students and postgraduate students of ancient philosophy.

What are the objects of science? Are they just the things in our scientific experiments that are located in space and time? Or does science also require that there be additional things that are not located in space and time? Using clear examples, these are just some of the questions that Scott Berman explores as he shows why alternative theories such as Nominalism, Contemporary Aristotelianism, Constructivism, and Classical Aristotelianism, fall short. He demonstrates why the objects of scientific knowledge need to be not located in space or time if they are to do the explanatory work scientists need them to do. The result is a contemporary version of Platonism that provides us with the best way to explain what the objects of scientific understanding are, and how those non-spatiotemporal things relate to the spatiotemporal things of scientific experiments, as well as everything around us, including even ourselves.

This collection of essays surveys a wide range of methods of Platonic interpretation, ranging from the dialogues themselves, to Middle and Neoplatonic interpretations of Plato's writings, to modern uses of Platonism. As a philosophical movement, Platonism is broadly conceived, covering schools and philosophers beginning with Plato and his immediate followers and extending through contemporary philosophers. The history of Platonism begins, of course, with Plato himself. But his adoption of the dialogue style and his active engagement with students in his Academy, where he certainly used dialectic techniques, led almost immediately to questioning what Plato's doctrines actually were. His student Aristotle raised questions of interpretations and invoked esoteric teachings not present in the written works. The earliest heads of the Academy struggled with Plato's texts as well, creating rival interpretations. These early discussions gave rise to later ones, and Platonism became simultaneously a dogmatic philosophy and a source of sometimes-heated debate of what the master intended. From its inception, Platonism was a dynamic philosophy, open to varied interpretations on different fronts while also maintaining a common core of beliefs. Platonism gave rise to methods of interpretation that centered on historical, ethical, political, or metaphysical questions engendered by Plato's writings. The ancient commentators reflected the teachings of their predecessors, and with only a few schools in the Greco-Roman world, many of their students studying under the same teachers, meant a heightened continuity in the tradition of interpretation. This volume honors the seventy-fifth birthday of John Dillon, the great scholar of Platonism whose scholarship had a pivotal role in defining Platonism as a philosophical movement in contemporary academia.

Plato's dialogue the Timaeus-Critias presents two connected accounts, that of the story of Atlantis and its defeat by ancient Athens and that of the creation of the cosmos by a divine craftsman. This book offers a unified reading of the dialogue. It tackles a wide range of interpretative and philosophical issues. Topics discussed include the function of the famous Atlantis story, the notion of cosmology as 'myth' and as 'likely', and the role of God in Platonic cosmology. Other areas commented upon are Plato's concepts of 'necessity' and 'teleology', the nature of the 'receptacle', the relationship between the soul and the body, the use of perception in cosmology, and the work's peculiar monologue form. The unifying theme is teleology: Plato's attempt to show the cosmos to be organised for the good. A central lesson which emerges is that the Timaeus is closer to Aristotle's physics than previously thought.

Platonism has played a central role in Christianity and is essential to a deep understanding of the Christian theological tradition. At times, Platonism has constituted an essential philosophical and theological resource, furnishing Christianity with an intellectual framework that has played a key role in its early development, and in subsequent periods of renewal. Alternatively, it has been considered a compromising influence, conflicting with the faith's revelatory foundations and distorting its inherent message. In both cases the fundamental importance of Platonism, as a force which Christianity defined itself by and against, is clear. Written by an international team of scholars, this landmark volume examines the history of Christian Platonism from antiquity to the present day, covers key concepts, and engages issues such as the environment, natural science and materialism.

In this book, Balaguer demonstrates that there are no good arguments for or against mathematical platonism. He does this by establishing that both platonism and anti-platonism are defensible. (Philosophy)

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.
