Apuleius and the Aristotelian De Mundo

Description

The De Mundo is a fascinating part of Apuleius’ corpus, with much to contribute to our understanding of Mediterranean philosophy in the second century, of philosophical work in the Latin language, of Platonism, and of Apuleius himself. But, sidelined as a mere translation (of the pseudo-Aristotelian work usually known by the same name), it has never received sustained attention in its own right. This workshop brings together an international team of scholars who will address the text from a range of disciplinary perspectives.

L’âme comme livre

Étude sur une image platonicienne

Karel Thein, Paris: Classiques Garnier, 2021

Description

Dans le Philèbe, Platon élabore une image de notre âme comme livre où un écrivain et un peintre sont constamment au travail. Cet ouvrage examine les prémisses implicites de cette image et met en cause l’idée d’une rupture entre la phantasia des Anciens et l’imagination des Modernes.

Ruhr Universität Bochum

Now, Exaiphnês and the Present Moment in Ancient Philosophy

Description and organisation

We are pleased to announce the conference Now, Exaiphnês and the Present Moment in Ancient Philosophy to take place at the Ruhr Universität Bochum, on the 24th-25th of March, 2022.

The experience of time is among the most fundamental features of human existence. The present thereby serves as a basis by means of which we can make sense of both past and future; thus our experience of the present, which we capture in notions like “the now”, “the instant of time”, or “the present moment”, is of special concern. We are made aware of the moment of time through motion and changes, and since the present moment seems to be when we experience these changes, our conception of the “now” is strongly connected with the notion of change. But experiencing a change means experiencing that something turns from being F to not being F, or from F to not-F. If the instants when something is F and not-F are the same instant, however, then the thing seems to be both F and not-F at the same time, and we seem to end up with a contradiction. This threatening inconsistency prompted several influential answers in ancient times: for example, Heraclitus may seem to endorse this inconsistency, while Parmenides seems to have concluded that time and change are thus unreal. Plato develops the notion of exaiphnês to suggest that the turning from F to not-F occurs outside of time. And Aristotle develops both Parmenidean and Platonic intuitions to argue that change is continuous and the segmentation of time into ‘nows’ occurs in thought.          

The problem of the present moment remains a source of lively philosophical debate and the ancient ideas are still a constitutive part of it, which is the motivation for organizing the conference “Now, Exaiphnes and the Present Moment in Ancient Philosophy”. The conference will bring together an international group of leading scholars working on these problems in different authors and traditions. Among the confirmed speakers are Ursula Coope (Oxford), Salvatore Lavecchia (Udine), Walter Mesch (Münster), Alex Pleshkov (Moscow), Spyridon Rangos (Patras), Mark Sentesy (Penn State), and Niko Strobach (Münster). And we also invite two to three speakers through this call for papers.

At the moment we hope the conference to take place in person, but are planning for a hybrid format as well. We expect the papers to be submitted to be about 30-45 minutes; each session will last an hour for the presentation and discussion combined. We will cover travel within Europe and accommodation.

Instructions for the submission of papers:

   Submit either full papers or extended abstracts of 1000-1500 words.

   Papers can be submitted in English or German

   Remove any identifying information on the abstract and include a separate document with your name, email, and affiliation.

   Abstracts should be sent as pdf documents to Celso Vieira (Celso.DeOliveiraVieira@rub.de).

   The subject of the email should be “Submission – Now Conference”. The title of the identification document should be the author’s name

   The submission deadline is January 03, 2022

   Notification of acceptance will be at the beginning of February

The Trinity Plato Center

The Theory and Practice of Cosmic Ascent

Comparative and Interdisciplinary Approaches

Description and organization

One of the most striking genres in the history of western thought is the account of cosmic ascent; we find narratives of humans ascending to the stars and beyond in a vast array of sources from among the earliest written accounts of western literature until the present day. How are we to interpret such accounts? Possibilities include reading them as tropological performances, as ritual prescriptions, as experiential accounts, as as some combination of these, but this list does not exhaust the hermeneutic options. Even a selective list of ancient and more recent ascent-accounts is striking for the vast range and widely-varied nature of the evidence. From the Hellenistic period onward, Mediterranean religions and philosophies looked increasingly to a model of human ascent as a primary locus for spiritual achievement; however, the ways in which such ascent was conceptualized vary enormously from tradition to tradition. This conference brings together specialists from a number of fields and methodological approaches with a view to expanding understanding of the significance of cosmic ascent-accounts.
The conference has been rescheduled and brought online. If you wish to attend, please send a message to the contact

Alexandre d’Aphrodise

Commentaire à la Métaphysique d’Aristote

Alexandre d’Aphrodise, Paris : Vrin, 2021

Description

Nous sommes heureux d’annoncer la parution de Alexandre d’Aphrodise, Commentaire à la Métaphysique d’Aristote. Livres Petit Alpha et Beta, introduction, traduction et notes par Laurent Lavaud et Gweltaz Guyomarc’h, Paris, Vrin, Bibliothèque des Textes Philosophiques, 2021. Parmi les commentateurs d’Aristote, Alexandre d’Aphrodise (IIe-IIIe siècles) est, depuis l’Antiquité, tenu pour « l’Exégète par excellence ». Titulaire de la chaire impériale de philosophie péripatéticienne à Athènes, il a rédigé nombre de commentaires aux œuvres d’Aristote. Son commentaire à la Métaphysique a servi à la fois de modèle et de source à la tradition ultérieure, des Néoplatoniciens grecs à la pensée médiévale byzantine, arabe et latine. Le livre Petit alpha de la Métaphysique lui donne l’occasion de revenir sur le projet général de la « sagesse » ou « philosophie première », qui guide l’ouvrage en son entier. Aux interprètes antérieurs, qui ont douté de l’authenticité et de l’appartenance du livre au traité, Alexandre répond qu’il ne peut être que l’œuvre d’Aristote. En organisant en un système déterminé les intuitions éparses de Petit Alpha, Alexandre transforme durablement la figure de la métaphysique aristotélicienne. Le livre Beta est, quant à lui, connu comme le livre des « apories », ces difficultés qui se posent à tout métaphysicien. Le livre constitue à ce titre, du point de vue d’Alexandre, le vrai commencement de la Métaphysique. Alexandre voit dans ces apories un moment proprement exploratoire, formant, de ce fait, autant de manières de mettre le métaphysicien en quête de la vérité. La traduction ici présentée est la première donnée en français de l’un des grands Commentaires lemmatiques qui ont fait la réputation d’Alexandre. Elle repose sur un texte grec révisé en profondeur.

Introduction, traduction et notes par L. Lavaud (petit Alpha) et G. Guyomarc’h (Beta).

Eros antico

Un percorso filosofico e letterario

Franco Trabattoni, Rome : Carocci Editore, 2021

Descrizione

Attraverso una studiata selezione di poeti e filosofi antichi il libro si propone di illuminare la complessa natura dell’eros nelle sue molteplici e a volte persino contraddittorie sfaccettature. Amore come abbandono, bisogno, dolore, ferita, fastidio, guerra, fatica; amore come pazzia, amore come possedere e come essere posseduto; amore come piacere impossibile; amore come ostacolo o impedimento, come errore da evitare o da superare; amore come bellezza senza passato, senza storia, senza genealogia, senza significato; amore come cosa che esiste e che appare senza motivo, senza bisogno di spiegazioni o commenti. Ma la potenza dell’eros non si riduce al tempestoso universo di eventi e di impulsi particolari, ben piantati in uno spazio e in un tempo precisi, o all’effimera apparizione di una bellezza che poi sfiorisce per sempre. L’amore, in quanto eterna e infinita vicenda di bisogno e soddisfazione, è anche apertura, rinvio ad altro. È l’amore che allude a un punto di fuga, a un anello che non tiene, a un luogo dove si insinuano la pretesa o la speranza di un senso che non si vede. L’amore non è solo frutto che si coglie e consuma; è anche seme che infinitamente rigenera e riproduce la vita.

Authority and Authoritative Texts

in the Platonist Tradition

Michael Erler, Jan Erik Hebler & Federico M. Petrucci, Cambridge, Cambridge University Press, 2021

Description

All disciplines can count on a noble founder, and the representation of this founder as an authority is key in order to construe a discipline’s identity. This book sheds light on how Plato and other authorities were represented in one of the most long-lasting traditions of all time. It leads the reader through exegesis and polemics, recovery of the past and construction of a philosophical identity. From Xenocrates to Proclus, from the sceptical shift to the re-establishment of dogmatism, from the Mosaic of the Philosophers to the Neoplatonist Commentaries, the construction of authority emerges as a way of access to the core of the Platonist tradition.
