Studies in Platonism, Neoplatonism, and the Platonic Tradition – serie

The nature and existence of time is a fascinating and puzzling feature of human life and awareness. This book integrates interdisciplinary work and approaches from such fields as physics, psychology, biology, phenomenology, and technology studies with philosophical analyses and considerations to explain a number of facets of the perennnial question of time's nature and existence, both in contemporary and in its initial classical Greek context; and it then explores and explains two of the most influential investigations of time in classical Western thought: Aristotle's, as presented in his Physics, and the (neo)Platonist Plotinus' in his treatise On Time and Eternity. Original interpretative perspectives are argued in both cases, and special attention is paid to Plotinus as partly responding to and critiquing Aristotle's account.

The Commentary of al-Nayrizi (circa 920) on Euclid’s Elements of Geometry occupies an important place both in the history of mathematics and of philosophy, particularly Islamic philosophy. It is a compilation of original work by al-Nayrizi and of translations and commentaries made by others, such as Heron. It is the most influential Arabic mathematical manuscript in existence and a principle vehicle whereby mathematics was reborn in the Latin West. Furthermore, the Commentary on Euclid by the Platonic philosopher Simplicius, entirely reproduced by al-Nayrizi, and nowhere else extant, is essential to the study of the attempt to prove Euclid’s Fifth Postulate from the preceding four. Al-Nayrizi was one of the two main sources from which Albertus Magnus (1193-1280), the Doctor Universalis, learned mathematics. This work presents an annotated English translation of Books II-IV and of a hitherto lost portion of Book I.

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.

John J. Cleary (1949–2009) was an internationally recognised authority in many aspects of ancient philosophy. As well as penetrating and original studies of Plato, Aristotle, and Proclus, he was particularly interested in the philosophy of mathematics, and ancient theories of education. The essays included in this collection display Cleary’s range of expertise and originality of approach. Cleary was especially attentive to the problems involved in the interpretation of a philosophical text: in his reading of Plato he recognised the special status of dialogue as a privileged mode of philosophical writing. His underlying concern was the open-ended character of philosophy itself, to be pursued with intellectual rigour and respect both for the question and one’s interlocutor. These collected essays are representative of John Cleary’s philosophical life’s work.

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.

Reading Proclus and the Book of Causes, published in three volumes, is a fresh, comprehensive understanding of Proclus’ legacy in the Hellenic, Byzantine, Islamic, Latin and Hebrew traditions. The history of the Book of Causes, an Islamic adaptation of mainly Proclus’ Elements of Theology and Plotinus' Enneads, is reconsidered on the basis of newly discovered manuscripts. This first volume enriches our understanding of the diverse reception of Proclus’ Elements of Theology and of the Book of Causes in the Western tradition where universities and religious schools offered unparalleled conditions of diffusion. The volume sheds light on overlooked authors, texts, literary genres and libraries from all major European universities from the 12th to the 16th centuries.

Reading Proclus and the Book of Causes, published in three volumes, is a fresh, comprehensive understanding of the history of Neoplatonism from the 9th to the 16th century. The impact of the Elements of Theology and the Book of Causes is reconsidered on the basis of newly discovered manuscripts and evidences. This second volume revises widely accepted hypotheses about the reception of the Proclus’ text in Byzantium and the Caucasus, and about the context that made possible the composition of the Book of Causes and its translations into Latin and Hebrew. The contributions offer a unique, comparative perspective on the various ways a pagan author was acculturated to the Abrahamic traditions.

In Plato's Timaeus and the Missing Fourth Guest, Donna M. Altimari Adler proposes a new Timaeus scale structure. She finds the harmonic cosmos, mathematically, at 35 A-36 D, regarding the text as a number generator. Plato's primary number sequence, she argues, yields a matrix defining a sophisticated harmony of the spheres. She stresses the Decad as the pattern governing both human perception and the generation of all things, in the Timaeus, including the World Soul and musical scale symbolizing it. She precisely identifies Plato's "fabric" and its locus of severance and solves other thorny problems of textual interpretation.

This study argues that late ancient Greek and medieval Islamic philosophers interpret human desire along two frameworks in reaction to Aristotle’s philosophy. The investigation of the model dichotomy unfolds historically from the philosophy of Plotinus through the Graeco-Arabic translation movement in 8th-10th century Baghdad to 12th century al-Andalus with the philosophy of Ibn Bāǧǧa and Ibn Ṭufayl. Diverging on desire’s inherent or non-inherent relation to the desiring subject, the two models reveal that the desire’s role can orient opposed accounts of human perfection: logically-structured demonstrative knowledge versus an ineffable witnessing of the truth. Understanding desire along these models, philosophers incorporated supra-rational aspects into philosophical accounts of the human being.

Reading Proclus and the Book of Causes, published in three volumes, is a fresh, comprehensive understanding of the history of Neoplatonism from the 9th to the 16th century. This third volume gathers contributions on key concepts of the Platonic tradition (Proclus, Plotinus, Porphyry or Sallustius) inherited and reinterpreted by Arabic (e.g. Avicenna, the Book of Causes), Byzantine (e.g. Maximus the Confessor, Ioane Petritsi) and Latin authors (e.g. Albert the Great, Thomas Aquinas, Berthold of Moosburg, Marsilio Ficino etc.). Two major themes are presently studied: causality (in respect to the One, the henads, the self-constituted substances and the first being) and the noetic triad (being-life-intellect).

The open access publication of this book has been published with the support of the Swiss National Science Foundation.In this book, Ota Gál presents a new analysis of Plotinus' conception of beauty, beginning from a close reading of treatises I.6 and V.8, which link beauty with the unified multiplicity of Intellect. This account is subsequently placed in a hierarchical and structural context in VI.2 and VI.6 and connected to illumination in VI.7, enabling us to determine the meaning of the predicate “beauty” at different ontological levels. For Plotinus, beauty is ultimately the illuminated unity in multiplicity of Intellect, which, as the manifestation of the Good, simultaneously enables the soul’s ascent and threatens to bind the soul to itself.

The Neoplatonic philosopher Plotinus invites us to take part in his philosophizing when he encourages his readers to think about what they think they are, as living beings, human beings, as rational beings, ethical subjects and as philosophers. He is interested in what we say about ourselves in ordinary language and notices that such ordinary experience conflicts with what the Platonic tradition claims we (truly) are. This conflict does not lead him to turn away from the human terms and expressions, but impels him to take seriously what we say about ourselves and to explain it philosophically.

This book gives us a new perspective on the Philosophy according to the Chaldean Oracles by Porphyry of Tyre (ca. 232/305 CE), demonstrating that much of what we thought we knew about this work and its fragments is mistaken. Here, for the first time, the attempt is made at reconstructing the original text by following the vicissitudes of its reception and transmission from Late Antiquity through the Middle Ages and the Renaissance up to modern scholarship. The extensive and painstaking study of the surviving fragments leads to the radically innovative conclusion that this encyclopedic treatise, written by Porphyry in the last decades of the 3rd century CE, consisted of fifteen books organized in various sections. After an initial discussion of the nature of theurgy and of its subordinate role with respect to philosophy, Porphyry describes the entire history of Greek philosophy from Homer up to his own teacher Plotinus, to then go on to present “introductions” to the seven encyclical disciplines whose study is required for the comprehension of theosophy, that is, the esoteric speculation on the three parts of philosophy: anthropology-ethics, physics, and metaphysics-theology.By harmonizing the teachings of Plato, Aristotle, Plotinus, and the Chaldean Oracles, Porphyry intends to present the complete and definitive philosophic system, with the aim of showing the universal way for the liberation of the souls of initiates and of contextually fighting the final battle of the Greco-Roman civilization against Christianity.

Plotinus’ Ennead III.7 is a treatise concerning the journey of the human soul first descending into time and then reclaiming its original identity in eternity. The treatise also conceives eternity as the key which grants access to the forms, and time as the portal through which the soul enters the physical universe. Plotinus supports his analysis by drawing upon a rich philosophical tradition including the thought of Plato, Aristotle, the Stoics, Epicureans, Peripatetics and Pythagoreans. This book contains an extensive introduction, alongside the Oxford Classical Text of III.7, a translation, and a line-by-line commentary to guide the reader through the text.

The book is a critical edition of the text with an English translation and commentary of Proclus’ On the Hieratic Art according to the Greeks. The Hieratic Art is the Theurgic Art, theurgy, the theurgic union with the divine. Proclus describes the theurgic union, putting an emphasis on a conceptual blending of ritual actions (teletai, e.g. the role of statues, incenses, synthêmata, symbols, purifications, invocations and epiphanies) and philosophical concepts (e.g. union of many powers, ‘one and many’, symphathy, natural sympathies, attraction, mixing and division).
