Project

Abstract:

NeoplAT offers a fresh and thoroughly documented account of the impact of Pagan Neoplatonism on the Abrahamic traditions. It focuses mainly, but not exclusively, on the Elements of Theology of Proclus (fifth century) which occupies a unique place in the history of thought. Together with its ninth-century Arabic adaptation, the Book of Causes, it has been translated, adapted, refuted and commented upon by Muslim, Jewish and Christian thinkers across centuries, up to the dawn of modernity. Despite a renewed interest in Proclus’ legacy in recent years, one still observes a tendency to repeat conventional hypotheses focused on a limited range of well-studied authors. This project radically challenges these conservative narratives both by analysing invaluable, previously ignored resources and by developing an innovative comparative approach that embraces a variety of research methods and disciplines. Specialists in Arabic, Greek and Latin history of ideas, philology, palaeography and lexicography develop an intense interdisciplinary research laboratory investigating the influence of Proclus on the mutual exchanges between the scriptural monotheisms from the ninth to the sixteenth centuries.

In ninth-century Baghdad and in the circle of the philosopher al-Kindī (c. 870), the nascent tradition of Arabic Peripateticism integrates the Platonic metaphysical work of Proclus into a corpus of writings, which it regards as Aristotelian. This coincides with the emergence of the transmission of a portion of Plotinus’ Enneads under the title The Theology of Aristotle; the Elements of Theology were translated and afterwards adapted to Islamic Mu‘tazilite theology into a new work bearing the title Kitāb fī Maḥḍ al-ḫayr (Discourse on the Pure Good), famously known as the Book of Causes. The author deliberately selected a series of propositions from the Elements of Theology and in some cases he combined several of them, thus compressing the 211 chapters of Proclus’ work into 31[32] in the Book of Causes. There are also significant doctrinal modifications, due to the adjustment of the emanatist Proclean metaphysics to an Islamic monotheist environment. Two of these changes are especially noteworthy: Proclus’ idea of emanative causality from the One to the Many is replaced with the idea of creation and the doctrine that a Supreme Being is cause of all beings. A second version of the Book of Causes has recently been identified and discussed, but its influence was extremely limited and never reached beyond the Middle East.

​

During the eleventh and twelfth centuries, the Elements of Theology were read by major figures within the Byzantine philosophical tradition (Michael Psellos, John Italos, Eustratios of Nicaea). Joanne Petritsi (d. 1125), who studied in Constantinople, possibly under Psellos, translated the Elements of Theology from Greek into Georgian and wrote an extensive commentary to accompany it. Concerned that certain thinkers in Byzantium were confusing Proclus’ thought with Christian doctrine, Nicholas of Methone (d. ca. 1166) wrote a lengthy Refutation of the Elements of Theology.

​

By the end of the twelfth century, the Arabic text of the Book of Causes was translated into Latin as the Liber de causis. In 1268, William of Moerbeke translated the Elements of Theology from Greek into Latin. Of all the traditions mentioned above, the Latin reception of the Elements of Theology and of the BoC is the most extensive, judging by the number of manuscripts transmitting the text and the number of commentaries addressing it. The standard literature mentions six thirteenth-century Latin commentaries on the Book of Causes (Roger Bacon, Ps.-Henry of Ghent, Albert the Great, Thomas Aquinas, Siger of Brabant and Giles of Rome) and a fourteenth-century commentary on the Elements of Theology by Berthold of Moosburg. Two sixteenth-century commentaries on the Book of Causes, by Chrysostomus Javelli and Jacob Gostynin have been almost constantly and inexplicably ignored by scholars. A single narrative has thus gained predominance through a range of highly influential studies. It claims that, after the 1280s, Neoplatonism was forgotten in Paris, and was taken up in Germany as an alternative to Parisian teaching. Henry Bate, Nicholas Cusanus, Marsilio Ficino and Pico della Mirandola would complete the list of rare authors who, from the end of the thirteenth century onwards, read either the Elements of Theology or the Book of Causes. The result, ultimately, is a desolate picture: interest in the Book of Causes declined after the Latin translation of the Elements of Theology in 1268, since medieval authors generally avoided confrontation with Proclus’ metaphysics. Until recently, these views have either been repeated or only cautiously questioned.

​

In Hebrew, there exist four known translations of the Book of Causes and three commentaries. Three translations are made from the Latin version (Hillel of Verona in 1260; Jehuda Romano in the fourteenth century; ‘Eli Ḥabilio in 1477) and one from the Arabic version (Zeraḥiyah Hen in 1280). These have been published and studied. Hillel of Verona wrote an original commentary (edited and translated into French by Rothschild 2017); Jehuda Romano partially translated the commentaries by Albert the Great and Thomas Aquinas, providing a fascinating witness to the cross-cultural influence of the Latin and, ultimately, Arabic traditions.

​

NeoplAT integrates the progress accomplished by the academic community, and builds on the recent identification of a large corpus of Latin manuscripts previously overlooked. It continues continues the search for new material and facilitates a much wider analysis enabling a broad comparative analysis of the reception of the Elements of Theology and the Book of Causes in the Abrahamic traditions. It gathers a large international team with experts in various disciplines. On the basis of comparative interpretations, the project develops an innovative method, which combines lexicographical, codicological and palaeographical studies with philosophical and theological analyses in Arabic, Greek and Latin. It aims to forge essential tools for extending the understanding of the dialogue between Abrahamic traditions, and to proffer a new reflection on this unconventional history of metaphysics.

The project is structured around four interrelated and fundamental questions that will be addressed through nine manageable specific tasks.

1. Where and when were the Elements of Theology and the Book of Causes read, taught and copied? Arabic philosophy is consigned to hundreds of thousands of manuscripts since, as we know, these works continued to be published in manuscript from the ninth to the nineteenth century. The networks of transmission between the lands of Islam and the Christian West are largely unexplored. These gaps in our understanding are due to a lack of a systematic examination of the immense manuscript collections in which these texts are preserved. Indeed, no methodical and extensive research has been undertaken in order to explain why, when and where Proclus arabus and the Book of Causes were copied in the lands of Islam. Similar difficulties beset scholars of the Latin tradition. The two lists published by Taylor (1983) mentioning Latin manuscripts containing the text of the BoC and commentaries on the work, while useful for a brief panorama, are neither descriptive nor exhaustive. Thus, at present, it is impossible fully to understand the modalities of the diffusion of the BoC in the Latin West: was it copied as a part of the corpus Aristotelicum? Was it more popular in the ‘traditional’ universities of Western Europe (Paris, Oxford) or rather in the newer universities of Central Europe (Prague, Krakow, Erfurt)? How many more remain undisclosed in the libraries?

​

2. What versions of the Elements of Theology and the Book of Causes were known in each tradition? Recent studies on Petritsi’s Georgian translation of the Elements of Theology seem to indicate that in eleventh- and twelfth-century Byzantium the text was considerably different from the version used from the thirteenth century onwards, on which is based the standard edition. Nicholas of Methone therefore read and refuted a version of the Elements of Theology which differs from the latter; the current critical edition containing numerous faulty transcriptions, omits the text of the Elements of Theology transmitted in the manuscripts of the Refutation.

​

The situation is comparable with the Western tradition of the BoC. Thomas Aquinas in 1270 and Giles of Rome in 1289/1291 observe in their exegeses on the BoC that the text they comment upon seems corrupt, and they check it across several manuscripts. How can one explain this deplorable state of the text less than one century after its initial translation and entry into the West? In what condition was the text transmitted to authors over subsequent centuries? Recent publications have shown that from the thirteenth to the fifteenth centuries, the text of the BoC had considerable variations. How can these be accounted for? Which version had the widest readership? These questions, although extremely important, have never been envisaged before since the current edition of the Book of Causes fully collates only ten out of two hundred and seventy known manuscripts, and thus does not do justice to the complex Latin tradition.

​

3. Who read the Elements of Theology and the Book of Causes? And what is their impact on the history of thought? The quantity and distribution of the manuscripts of these two works are certainly the most important witnesses to the interest they received across the centuries and in different intellectual milieus. While their presence in the lands of Islam requires further extensive investigation, the Western tradition has begun to be uncovered in recent publications. In order to grasp their enduring influence on the history of thought, one needs to analyse the exegeses of them that span over three hundred years. In the majority of cases, these exegeses are the results of lectures, since the Book of Causes was included in the curricula of various institutions across Europe. These authors, although today they are less known or anonymous, had a considerable influence on generations of students: they provided conceptual tools to reflect both on pagan texts and on their Christian tradition; gradually, their ideas have been integrated into Western models of rationality, even if these distant origins are often unacknowledged today (e.g. the notion of “first” and “secondary causes” used in modern philosophy, elaborated mainly in the Book of Causes). However, the majority of these commentaries are still unedited. To edit and to study these texts is the only way to access the uninterrupted tradition of instruction and commentary on the Elements of Theology and the Book of Causes and to attain a better understanding of the dynamics of mutual exchange between scriptural monotheisms.

​

4. How and why were the Elements of Theology and the Book of Causes assimilated into these various traditions? For each cultural milieu, one notices different modes of interpretation at the level of form and literary genre: translation and transformation in the lands of Islam; commentary and refutation in Byzantium; translation and teaching in the West. To what extent do these reflect the institutional and doctrinal contexts which give rise to these commentaries? What are the mechanisms of exchange that enable both the encounter of these scriptural monotheisms with a system of thought originating in Greek polytheism (through the Elements of Theology), as well as the unwitting assimilation of Islamic Mu‘tazilite theology into Christian contexts (through the Book of Causes)?

​

Within the circle of the philosopher al-Kindī, the decision to attribute the Book of Causes to Aristotle witnesses to the search for harmony between Platonism and Peripateticism. To what extent does it reflect a certain vision of Islam? Latin authors inherit the same misattribution and spread this view throughout the universities. Was it the case that the Elements of Theology and the Book of Causes were regarded as Christian (or potentially Christian) versions of Aristotle’s metaphysics? These similar situations seem to indicate that the direct or indirect confrontation with Proclean metaphysics stimulates reflection on the central themes of the Abrahamic traditions. These topics interrogate the history of thought from yet another angle, for in each of these traditions, for several centuries, the relations between theology and philosophy, reason and faith was particularly complex and porous, as well as the boundaries between the Latin Christian and Greco-Arabic intellectual culture.

​

By answering these questions, the project’s intention is to forge a broad comparative approach that enables a thorough understanding of the reception of Proclus in the Middle East, Byzantium and the Latin West.

giovana.jpg

Giovanna Bagnasco (Researcher at UCD, 2022-2023)

After studying philosophy and classical literature at the University of Pavia, Italy, ​I continued ​my studies at the Universities of Lausanne and Fribourg (​Switzerland) and in 2013 I completed ​my PhD in medieval philosophy under the direction of ​Professor ​Ruedi Imbach (Sorbonne-Paris IV​, France​) and ​Professor ​Carla Casagrande (University of Pavia​, Italy​).  ​I am particularly interested in the philosophy of Heymericus de Campo, Flemish author of the fifteenth century and friend and teacher of Nicholas of Cusa, because of the particular attention that Heymericus shows in the doctrines of Albertus Magnus, Nicholas of Cusa, Alain of Lille and Ramon Llull.  I have recently published for Brepols the Centheologicon of Heymericus de Campo in the Corpus Christianorum (2020). Within the project NeoplAT, I have undertaken the transcription and study of another work of Heymericus, the De formis intentionalibus, a treatise of metaphysics and logic, investigating the question of the intentionality of sensible and intelligible forms in knowledge. I am also a teacher at the Classical High School of Mantova (Italy).

​Odile Gilon (Chargé de cours en philosophie médiévale, Université libre de Bruxelles / Researcher at UCD, 2021-2023)

After having studied philosophy at the Université libre de Bruxelles (ULB), she graduated with a PhD on the metaphysics of Duns Scotus ("Indifférence de l’essence et métaphysique chez Jean Duns Scot"), co-directed by Olivier Boulnois (EPHE, Paris) in 2009 and published in 2012 (with Ousia). She is currently teaching philosophy in several schools in Brussels (HEFF, ISURU) and medieval matters at ULB. The main frame of her research is about metaphysics in the Franciscan school, history of melancholia and attention.
Within the NeoplAT project she will revise the Latin edition, provide the first-ever French translation and running commentary of an early 13th-century commentary on the Book of Causes, generally attributed to Roger Bacon.​

pursued his masters (MSc, MSc by Research) at the University of Edinburgh and PhD at the LMU Munich (Munich School of Ancient Philosophy), where he focused on the first cause in the two late Neoplatonists, Proclus and Damascius. Within the project, he studies the reception of Proclus’ notion of divine causality and the first principle in the late Byzantines (11-14th cent’s. A.D.), with special focus on the Byzantine commentator on Proclus, Nicholas of Methone.

evan.jpg

Evan King (Postdoctoral Fellow at UCD, 2019-2023)

obtained a BA in Humanities at Briercrest Bible College (2015) and MA in Classics at Dalhousie University, Halifax (2018). At UCD he prepares a PhD in Medieval Philosophy on the concept of "noble soul" in the Latin West. His research examines the concept in the Book of Causes as a translation of Proclus’ “divine soul,” and the reception and impact of this modification from the 13th-15th centuries. This study ranges from the published and unpublished commentaries on the Book of Causes to Berthold of Moosburg's Commentary on Proclus's Elements of Theology, and other relevant texts.

Dr Denoël’s current research project is the study of book illumination in France during the tenth and eleventh centuries seeks to present the diverse products of this time of intense creativity, in order to create both the first comprehensive study of illuminated manuscripts of this period and a robust, analytic historiography to frame their place in art history.

Dr Adrian Papahagi (University “Babes-Bolyai” Cluj-Napoca), “Hic magis philosophice quam catholice loquitur: Latin and Vernacular Traditions of Boethius’ De Consolatione Philosophiae in the Early Middle Ages” (February 5, 2021, on Zoom).

 

 

Boethius’ De consolatione Philosophiae, written in 524 and rediscovered in the last decades of the eighth century, was immensely popular in the Early Middle Ages. This presentation explores the Carolingian, Ottonian and Anglo-Saxon manuscripts of the Consolatio, the nature of their glosses and commentaries, as well as the Old English and Old High German translations made around 900 viz. around 1000, in an attempt to understand how several Neoplatonic elements of Boethius’ doctrine were received.

 

Adrian Papahagi has a PhD in Medieval Studies (Sorbonne), and is currently an associate professor at the Babeș-Bolyai University of Cluj, Romania. His publications include studies on Boethius’ fortune in the Early Middle Ages (Boethiana Mediaevalia, Bucharest, 2010), an exploration of fate and providence in Old English literature (Wyrd, Cluj, 2014), and a census of Western medieval manuscripts in Romania (Manuscrisele medievale occidentale din România: Census, Iași, 2018, with AC Dincă, and A. Mârza).

Rodrigo Ballon Villanueva (University of Lugano), “Unveiling Apokatastasis? Eriugena’s Eschatology and Essential Causality” (October 14, 2020 – via Zoom)

The doctrine of apokatastasis is one of the most distinctive and important notions of the Carolingian philosopher John Scotus Eriugena. The Irishman can be regarded, without hesitation, as the greatest medieval proponent of this eschatological view. In recent years, the centrality of the topic has been recognised and has attracted the attention of several scholars, who, in turn, tend to see it as a consequence of Eriugena’s Origenism. However, despite the clear intention of Eriugena to find support for his view in the works of Patristic authors, the truth is that he develops a peculiar understanding of the eschatological events. The present paper argues that Eriugena’s doctrine of apokatastasis is an essential aspect of his metaphysics that needs to be understood in relation with his overlooked theory of causa essentialis. 

Socrates-Athanasios Kiosoglou (KU-Leuven), “The Theory of Στοιχείωσις”, (July 23, 2020 – via Zoom)

Proclus’ Commentary on the First Book of Euclid’s Elements constitutes not only a systematic commentary on the Elements, but also a very rich source of metho-dological precepts about the proper writing and construction of a good Στοιχείωσις. By its very nature, a Στοιχείωσις is written for uninitiated students and novices, not for experts. Its purpose lies exactly in guiding learners of limited knowledge and familiarise them with the most basic and fundamental doctrinal assumptions of an epistemic domain. It would not be an exaggeration to say that the Commentary on Euclid (and notably the Prologues) is probably the only lengthy extant exposition of the main characteristics of the literary genre of Στοιχείωσις. The second Prologue includes the most essential, indispensable and probably interdisciplinary features of the style, that is, the features shared by all Στοιχειώσεις, regardless of their particular content and the domain they belong. The best way to capture Στοιχείωσις in another language is not Elements (like Dodds) or Elementa (like Patrizius, the Renaissance translator), but Elementatio (like Moerbeka, the Medieval translator) or Grundlegung (recalling Kant’s Gundlegung zur Metaphysik der Sitten).

Ezequiel Luduña (University of Buenos Aires), “The Intratrinitarian dynamics of Berthold of Moosburg’s Expositio Procli” (June 10, 2020 – via Zoom)

Berthold of Moosburg’s Expositio Procliis considered the most important testimony of the interest in Proclus’ thought during the 13th and 14th centuries in the Latin West known to date. Berthold brings into the Latin Tradition some doctrinal elements from Pagan Neoplatonism that conflict with basic tenets established by the philosophical milieu within which he writes. The most important has to do with the transcendence of the Principle. According to Berthold, the prime unumis beyond the intellectual realm. However, there are certain passages of theExpositio, where Berthold writes about the natura intelectualisof the Principle, that suggest that his attitude was not as bold as the other remarks about transcendence might imply. It is in this sense, when describing the prime unum as a natura intellectualis, that he includes the absolute One among those principles that are per se subsistentes(i.e. authypostata) and indicates that its processus originalisis nothing else than the Intratrinitarian processions.  

Dr William Duba (University of Fribourg), “Fragmentarium and Fragmentology” (June 16, 2020 – via Zoom)

A concise and clear presentation of the project Fragmentarium (https://fragmentarium.ms/) studying fragments of medieval manuscripts, and further theoretical considerations establishing a new discipline: fragmentology.

Dr Joshua Robinson (Dumbartoan Oaks Library, Harvard University), “The Themes of Divine Motion and Fecundity (γονιμότης) in Nicholas of Methone’s Refutation of Proclus, and their Patristic and Neopythagorean (?) Precedents” (May 13, 2020 – via Zoom)

What are the fundamental principles that guide Nicholas of Methone’s response to Proclus in his mid-12th-century Refutation of the Elements of Theology? As a general answer, one might simply say “Christian doctrine.” But a close reading of the Refutation reveals two distinctive emphases, the ideas of divine fecundity and divine motion. These ideas are rooted in Gregory of Nazianzus and Dionysius the Areopagite, and are creatively combined and deployed by Nicholas in ways that suggest further debts to John of Scythopolis, Maximos the Confessor, and John of Damascus. For Nicholas, the Trinity is understood in terms of a transcendent fecundity and motion that is the source and paradigm of all creaturely fecundity and motion. In contrast to the unmoved mover of classical philosophy, for Nicholas God as Trinity is understood as “self-moved,” the very model and source of that self-motion in creatures that is rational freedom. If we consider the key text of Gregory of Nazianzus in which Nicholas grounds his position, “the Monad, moved to Dyad and at Triad came to a halt,” we find suggestions that this statement in turn probably has connections to neo-Pythagorean currents of thought, appropriated by Gregory to make a Trinitarian point.

Dr Jonathan Greig (Austrian Academy of Sciences, Vienna), “Nicholas of Methone and Aquinas on Participation in Proclus’ Elements of Theology Prop. 23: Common and Contrasting Critical Readings” (May 6, 2020 – via Zoom).

One of Proclus’ more well-known positions is his view of participation, encapsulated in the Elements of Theology, Prop. 23, where participation results in three terms: the unparticipated, participated, and participant. For Proclus this necessitates a distinction between the One, as first cause, and the Henads, as mediators of the One’s causality—and thus as a plurality of gods. For the Christian inheritors of Proclus and his model of participation, this of course represents a problem. This paper compares the approach of two medieval Christian commentators on Proclus: the 12th-cent. Byzantine, Nicholas of Methone, and the 13th-cent. Latin scholastic, Thomas Aquinas. Drawing from their common source in Ps.-Dionysius, the two take divergent approaches in their notion of participation. While both do away with Proclus’ separately participated—i.e. the gods—both still accept the notion of participation as mediated, but in differing ways: for Nicholas the participated is subsumed into God, so that God is directly participated, albeit under specific aspects; for Thomas, the participated is subsumed into the level of creatures, so that God is indirectly participated in virtue of created, mediated properties immanent in creatures. 

Marc Geoffroy, “Aristotélisation de la gnoséologie néoplatonicienne dans le Kalām fī maḥḍ al-khair” [16 April 2016, Paris, EPHE]

mark geoffrey.png

Marc Geoffroy (1965-2018), during a conference held in Paris, delivered an exceptional paper on the transformation of Proclus’ Elements of Theology into Kalām fī maḥd al-khair (Liber de causis). He explained the relationship between proposition 123 of the Elements of Theology and proposition V(VI) of the Book of Causes, stressing the variety of philosophical sources used (notably Aristotle’s De anima and De sensu et sensato) and, in a Muʻtazilite milieu, the vocabulary recalling the Qurʾān. Unfortunately, the written text of this paper could not be found. Marc Geoffroy agreed to be part of the NeoplAT project and produce a running commentary on the Book of Causes, notably on its various philosophical and theological sources.

Paper introduced by Richard Taylor, and discussed (in order) by Philippe Hoffmann, (unrecognizable), Michael Chase, Richard Taylor.
