This Festschrift honors the life and work of John D. Turner (Charles J. Mach University Professor of Classics and History at the University of Nebraska at Lincoln) on the occasion of his 75th birthday. Professor Turner’s work has been of profound importance for the study of the interaction between Greek philosophy and Gnosticism in late antiquity. This volume contains essays by international scholars on a broad range of topics that deal with Sethian, Valentinian and other early Christian thought, as well as with Platonism and Neoplatonism, and offer a variety of perspectives spanning intellectual history, Greek and Coptic philology, and the study of religions.

The point of view put forth in the following pages differs greatly from the common perspective according to which the treatises 30 to 33 constitute a single work, a Großschrift, and this single work, Plotinus’ essential response to the Gnostics. Our perspective is that of an ongoing discussions with his “Gnostic”—yet Platonizing—friends, which started early in his writings (at least treatise 6), developed into what we could call a Großzyklus (treatises 27 to 39), and went on in later treatises as well (e. g. 47-48, 51). The prospect of an ongoing discussion with the Gnostics bears an additional virtue, that of allowing for a truly dynamic understanding of the Plotinian corpus.

In recent decades our view of Gnosticism has been revolutionized by the discovery of a Coptic Gnostic library at Nag-Hammadi, Egypt. Currently, Gnosticism is seen as a phenomenon extending far beyond Christianity and displaying a strong Platonic influence. The opposition between the two systems was certainly not as sharp as Plotinus claimed. Where, why, and how the ideological lines were drawn is discussed in the light of the new historical evidence.

The Routledge Handbook of Neoplatonism is an authoritative and comprehensive survey of the most important issues and developments in one of the fastest growing areas of research in ancient philosophy. An international team of scholars situates and re-evaluates Neoplatonism within the history of ancient philosophy and thought, and explores its influence on philosophical and religious schools worldwide. Over thirty chapters are divided into seven clear parts: (Re)sources, instruction and interaction Methods and Styles of Exegesis Metaphysics and Metaphysical Perspectives Language, Knowledge, Soul, and Self Nature: Physics, Medicine and Biology Ethics, Political Theory and Aesthetics The legacy of Neoplatonism. The Routledge Handbook of Neoplatonism is a major reference source for all students and scholars in Neoplatonism and ancient philosophy, as well as researchers in the philosophy of science, ethics, aesthetics and religion.

Spiritual Taxonomies and Ritual Authority recounts how philosophers of the late third century C.E. organized the spirit world into hierarchies, positioning themselves as high priests in the process. By establishing themselves as experts on sacred matters, they fortified their authority, prestige, and reputation.

By questioning the modern categories of Plato and Platonism, this book offers new ways of reading the Platonic dialogues and the many traditions that resonate in them from Antiquity to Post-Modernity.

Ritual, magic, liturgy, and theurgy were central features of Gnosticism, and yet Gnostic practices remain understudied. This anthology is meant to fill in this gap and address more fully what the ancient Gnostics were doing. While previously we have studied the Gnostics as intellectuals in pursuit of metaphysical knowledge, the essays in this book attempt to understand the Gnostics as ecstatics striving after religious experience, as prophets seeking revelation, as mystics questing after the ultimate God, as healers attempting to care for the sick and diseased. These essays demonstrate that the Gnostics were not necessarily trendy intellectuals seeking epistomological certainities. They were after religious experiences that relied on practices. The book is organized comparatively in a history-of-religions approach with sections devoted to Initiatory, Recurrent, Therapeutic, Ecstatic, and Philosophic Practices. This book celebrates the brilliant career of Birger A. Pearson.
