One of his six introductions to philosophy, widely used by students in Alexandria, Ammonius' lecture on Porphyry was recorded in writing by his students in the commentary translated here. Along with five other types of introductions (three of which are translated in the Ancient Commentators on Aristotle volume Elias and David: Introductions to Philosophy with Olympiodorus: Introduction to Logic) it made Greek philosophy more accessible to other cultures. These introductions became standard in Ammonius' school and included a popular set of five or more definitions of philosophy, some of them drawn from commentaries on quite different works. Ammonius' lecture expounded the most celebrated and discussed previous introduction written by Porphyry 200 years earlier, which was devoted to five main technical terms of Aristotle's logic. Ammonius was sympathetic to Porphyry because they both sought to harmonise the views of Plato and Aristotle with each other, arguing in different ways that the two philosophers did not disagree about the nature of universals. Porphyry's introduction was a hugely influential work for centuries after its composition, and this commentary by Ammonius served to maintain its position at the centre of later schools of philosophy. This English translation of Ammonius' work is the latest volume in the Ancient Commentators on Aristotle series and makes this philosophical work accessible to a modern readership. The translation is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index.

In 2021, a previously unknown treatise by Porphyry of Tyre, which has been preserved in a Syriac translation, was made available to historians of philosophy: Porphyry, On Principles and Matter (De Gruyter, 2021). This text not only enlarges our knowledge of the legacy of the most prominent disciple of Plotinus but also serves as an important witness to Platonist discussions of first principles and of Plato’s concept of prime matter in the Timaeus. The aim of the present volume of collected studies is two-fold. On the one hand, it brings up an update to the state of the art of our knowledge of Porphyry’s philosophy and of his role in the transmission of the earlier philosophical materials, especially those of the Middle Platonic works. On the other hand, it focuses on the questions of the reception of Porphyry’s legacy, both by Greek and Latin Platonists (with special interest in Calcidius) and by Christian Oriental authors (with particular focus on the Syriac tradition). The primary audience of the book will be scholars and graduate students in ancient and late ancient Greek philosophy, Orientalists and scholars interested in the Christian reception of Greek philosophy, in the studies of the Christian Orient, as well as in Greek, Latin, and Syriac philology.

Pagan rhetor, (Neo-)Platonist philosopher, Christian theologian This collection of essays is devoted to the rhetoric, Neoplatonic philosophy, and Christian theology of Marius Victorinus, a mid-fourth-century professor of rhetoric and philosopher who converted to Christianity late in life. Scholars from eight different countries, some of whom have not previously published in English, reflect on debates about his writings and theological development. These topics include Victorinus's deployment of philosophical sources for trinitarian theology, possible connections in his work to Origen, Augustine, Plotinus, Porphyry, and Gnosticism, as well as his contributions to Latin rhetoric and dialectic. Contributors include Jan Dominik Bogataj, Michael Chase, Nello Cipriani, Stephen A. Cooper, Volker Henning Drecoll, Lenka Karfíková, Josef Lössl, Václav Němec, Thomas Riesenweber, Guadalupe Lopetegui Semperena, Miran Špelič, Chiara O. Tommasi, John D. Turner, and Florian Zacher. The chapters in this volume are of great interest to students of late antique philosophy, Christian theology, and Latin rhetoric.

Crossing the Stream, Leaving the Cave brings philosophers from two of the world's great philosophical traditions--Platonic and Indian Buddhist--into joint inquiry on topics in metaphysics, epistemology, mind, language, and ethics. An international team of scholars address selected questions of mutual concern to Buddhist and Platonist: How can knowledge of reality transform us? Will such transformation leave us speechless, or disinterested in the world around us? What is cause? What is self-knowledge? And how can dreams shed light on waking cognition? What do the paradoxes thrown up by abstract thought about fundamental notions such as being and unity reveal? Is it possible to attain unity in ourselves, and should we even try? Would doing so make us happy--and is such happiness consistent with both contemplation of reality and action in the world? With close readings of texts by Buddhaghosa, Nagarjuna, Vasubandhu, Dignaga, Bhaviveka, Santideva; by Plato, Plotinus, Porphyry, Olympiodorus, and Damascius (among others), these studies consider not just the different answers Buddhists and Platonists might give to these questions, but also the criticisms they might bring to each other's positions, the sort of arguments they use, and the use they put these arguments to. Bringing Platonic and the Buddhist perspectives jointly to bear creates a cosmopolitan philosophical exchange which yields greater conceptual clarity on the questions and the terms in which they are cast, reveals unnoticed conceptual connections, and opens up new possibilities for addressing central philosophical concerns.

This book returns to the question at the center of our existence, a question that the narcissistic culture in which we are immersed systematically tends to remove: “Why?” The underlying thesis is that the answer must not be sought in success or social recognition, but in a “fragment of truth”, hidden somewhere inside each of us, which reveals itself only if we detach ourselves from our ego and its certainties. It is not, therefore, a matter of finding yet another philosophical theory of the meaning of existence, but rather of shedding light on the conditions under which such meaning can emerge. The author shows us that the ultimate source of our existential orientation lies in the affective sphere, and that the current crisis of orientation is derived from the atrophy of the process of affective maturation on a large scale, and from a lack of knowledge and experience about which techniques are best to reactivate it. We are like glowworms that had once unlearned how to illuminate and have since begun to hover around the magic lantern of the ascetic ideal, already criticized by Nietzsche, and then around neon advertising signs. We are glowworms that have forgotten that we have within our own affective structure a precious source of orientation. The basic thesis is that this source of orientation can be reactivated through the care of desire and practices of emotional sharing.

Philosophy in antiquity was conceived not as mere theory but as a way of life; but it lost its 'practicist' cast through a process that begins in the patristic era and peaks with its conversion into an academic discipline in the medieval universities under the influence of 13th-century scholasticism. Juliusz Domański sets out the reasons behind that process and shows how traces of the 'practicist' orientation survived, ultimately leading to a recovery of the ancient notion among the humanists of the Renaissance. A foreword by Pierre Hadot relates Domański’s research to his own vision of the history of philosophy.
