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.

Blake E. Hestir's examination of Plato's conception of truth challenges a long tradition of interpretation in ancient scholarship.

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.

The clean separation between manifold phenomena and a systematic order that prevails in them is a basic feature of the rational-scientific orientation system. The first authoritative formulation of this premise is found in Plato. His discussion of constitutive forms of world events has initiated a broad development in the history of philosophy, which is also effective today in the preference for reason-guided analyses of often confusing circumstances. The authors of this volume address the lasting relevance of this idea within two interrelated areas of research, namely Plato scholarship and contemporary Platonism. Of particular interest is the relationship between Plato and Wittgenstein. Following this overall idea, this volume is divided into three sections: Plato scholarship, Platonism, and Plato and Wittgenstein. As the contributions show, Platonism proves to be not only a purely historical-exegetical field of research but rather a fruitful stimulus for contemporary discussions on logical, linguistic, and social topics.

Heidegger's Platonism challenges Heidegger's 1940 interpretation of Plato as the philosopher who initiated the West's ontological decline into contemporary nihilism. Mark A. Ralkowski argues that, in his earlier lecture course, On the Essence of Truth, in which he appropriates Plato in a positive light, Heidegger discovered the two most important concepts of his later thought, namely the difference between the Being of beings and Being as such, and the 'belonging together' of Being and man in what he eventually calls Ereignis, the 'event of appropriation'. Ralkowski shows that, far from being the grand villain of metaphysics, Plato was in fact the gateway to Heidegger's later period. Because Heidegger discovers the seeds of his later thought in his positive appropriation of Plato, this book argues that Heidegger's later thought is a return to and phenomenological transformation of Platonism, which is ironic not least because Heidegger thought of himself as the West's first truly post-Platonic philosopher.

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.
