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.

This collection of essays delineates the history of the rather disparate intellectual tradition usually labeled as "Platonic" or "Neoplatonic". In chronological order, the book covers the most eminent philosophic schools of thought within that tradition. The most important terms of the Platonic tradition are studied together with a discussion of their semantic implications, the philosophical and theological claims associated with the terms, the sources that furnish the terms, and the intellectual traditions aligned with or opposed to them. The contributors thereby provide a vivid intellectual map of the Middle Ages and the Early Modern period. Contributions are written in English or German.

Neoplatonic Demons and Angels is a collection of eleven studies which examine, in chronological order, the place reserved for angels and demons not only by the main Neoplatonic philosophers (Plotinus, Porphyry, Iamblichus, and Proclus), but also in Gnosticism, the Chaldaean Oracles, Christian Neoplatonism, especially by Pseudo-Dionysius the Areopagite. This volume originates from a panel held at the 2014 ISNS meeting in Lisbon, but is supplemented by a number of invited papers.

Plato's doctrine of the soul, its immaterial nature, its parts or faculties, and its fate after death (and before birth) came to have an enormous influence on the great religious traditions that sprang up in late antiquity, beginning with Judaism (in the person of Philo of Alexandria), and continuing with Christianity, from St. Paul on through the Alexandrian and Cappadocian Fathers to Byzantium, and finally with Islamic thinkers from Al-kindi on. This volume, while not aspiring to completeness, attempts to provide insights into how members of each of these traditions adapted Platonist doctrines to their own particular needs, with varying degrees of creativity.

Porphyry's "Against the Christians" offers an important example of Hellenic Biblical criticism and a critique of Christianity at the close of Late Antiquity, fl. 300 C.E.
