This book is a slightly emended version of a dissertation presented at the University of Hull in 1972. I realise only too well the deficiencies of style, presentation and material which this involves. The title implies a more final note than I had intended in my treatment of Porphyry. On reflexion, however, it seemed the most suited to convey the general purpose of my enquiries. A more rounded assessment of Porphyry can come only after some more basic work has been completed. An edition of his philosophical fragments, to which I am now turning my attention, is a prerequisite. lowe, of course, a great deal to all those who have written on Neo platonism. I am particularly indebted to Prof. Willy Theiler under whose guidance I studied in Bern. Conversation with him always resulted in new directions of enquiry and I was constantly stimulated by his breadth of knowledge. I must also thank Prof. A. H. Armstrong who has constantly encouraged me and helped me to look more deeply into a number of problems. Welcome, too, was a detailed criticism of Part Two by Dr. R. T. Wallis. Their criticism and advice have not always been followed and the responsibility for the faults and weak nesses of this book rests on myself.

This book explores the intimate connections, conflicts and discontinuities between religion and philosophy in the Platonic and Neoplatonic traditions from Antiquity to the early Medieval period. It presents a broader comparative view of Platonism by examining the strong Platonist resonances among different philosophical/religious traditions, primarily Jewish, Christian, Islamic and Hindu, and suggests many new ways of thinking about the relation between these two fields or disciplines that have in modern times become such distinct and, at times, entirely separate domains.

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.

The work of Pseudo-Dionysius the Areopagite stands at a cusp in the history of thought: it is at once Hellenic and Christian, classical and medieval, philosophical and theological. Unlike the predominantly theological or text-historical studies which constitute much of the scholarly literature on Dionysius, Theophany is completely philosophical in nature, placing Dionysius within the tradition of ancient Greek philosophy and emphasizing, in a positive light, his continuity with the non-Christian Neoplatonism of Plotinus and Proclus. Eric D. Perl offers clear expositions of the reasoning that underlies Neoplatonic philosophy and explains the argumentation that leads to and supports Neoplatonic doctrines. He includes extensive accounts of fundamental ideas in Plotinus and Proclus, as well as Dionysius himself, and provides an excellent philosophical defense of Neoplatonism in general.

Athenian and Alexandrian Neoplatonism and the Harmonization of Aristotle and Plato by I. Hadot deals with the Neoplatonist tendency to harmonize the philosophies of Plato and Aristotle. It shows that this harmonizing tendency, born in Middle Platonism, prevailed in Neoplatonism from Porphyry and Iamblichus, where it persisted until the end of this philosophy. Hadot aims to illustrate that it is not the different schools themselves, for instance those of Athens and Alexandria, that differ from one another by the intensity of the will to harmonization, but groups of philosophers within these schools.

The belief in the immortality of the soul has been described as one of the “twin pillars of Platonism” and is famously defended by Socrates in Plato’s Phaedo. The ancient commentaries on the dialogue by Olympiodorus and Damascius offer a unique perspective on the reception of this belief in the Platonic tradition. Through a detailed discussion of topics such as suicide, the life of the philosopher and arguments for immortality, this study demonstrates the commentators’ serious engagement with problems in Plato’s text as well as the dialogue's importance to Neoplatonic ethics. The book will be of interest to students of Plato and the Platonic tradition, and to those working on ancient ethics and psychology.
