Titre de la thèse : "La notion d'hexis dans l’éthique aristotélicienne : la possibilité du développement de soi et la question du déterminisme"
Direction : Mme Cristina Viano
Résumé du projet de thèse : Bien que Platon l’utilise déjà dans ses écrits, le concept d’hexis est établi par Aristote dans son usage technique, et son importance dans les Éthiques ne peut pas être assez soulignée. Aristote développe une idée qui touche aussi bien l’ontologie que l’éthique : nous devenons ce que nous faisons. Le philosophe nous parle d’excellence naturelle, des caractéristiques liées à une naissance bienheureuse - mais il y a aussi dans les Éthiques une porte ouverte au changement de soi. Nos actions constituent nos états, nos qualités durables. D’une certaine façon, l’individu tout entier peut être envisagé au travers de l’hexis : elle nous renvoie et aux questions physiques et aux problématiques de la décision et du discernement de la mesotês. Les vertus ou vices adoptés par l’individu le constituent, puisque c’est à partir de ces états que change sa vision du bien vers lequel il doit se diriger. Dit d’une autre façon, nos actions nous déterminent dans notre être. Ainsi, nous nous trouvons devant un cercle : l’action modèle l'hexis, l’'hexis détermine l’action. Ce cercle conceptuel conduit automatiquement à la question du commencement : quelle est la racine profonde de l’êthos chez Aristote ? Notre étude visera à trouver la réponse à cette question à travers une analyse détaillée du concept d’hexis dans l’œuvre d’Aristote, en se concentrant spécialement sur son rôle dans les Éthiques. Ensuite, nous serons naturellement conduits vers la question « Pouvons-nous changer notre caractère volontairement selon Aristote ? ». Et, si cela est possible, « jusqu’à quel point sommes- nous capables de nous déterminer nous-mêmes ? » En nous dirigeant vers des réponses adéquates, notre étude permettra de comprendre mieux quelle était la théorie d’Aristote sur le mécanisme de décision qui se cache derrière nos actions, tout en ouvrant la porte au débat sur le déterminisme chez Aristote.

Titre de la thèse : "L’analogie aristotélicienne entre la perception et l’intellection"
Direction : Mme Anca Vasiliu
Résumé du projet de thèse :
Ce projet de thèse s’articule autour d’une certaine tension qu'on peut retrouver chez Aristote entre son approche vis-à-vis de la problématique du changement, d'une part, et un certain type de transformations – surtout manifestées dans la description des processus noétiques et perceptives, mais aussi présentes dans d'autres parties de sa science de la nature (plus précisément dans l'interprétation de la translation des éléments) – un type de transformations qui semblent échapper à la définition du mouvement et du changement, telle qu'elle est présentée dans Phys. 1.7 et Met. ? 1-3. Afin de retrouver la source de cette tension, on va circonscrire le rôle (“physique” et “herméneutique”) joué par la lumière (to phôs) dans le processus perceptif visuel et dans celui de l’intellection, chez Aristote et ses commentateurs anciens, tout en mettant en relief les liens conceptuels platoniciens qui relient tacitement le De Anima avec le Timée, le Philèbe, la République, vis-à-vis des notions essentiels comme “khôra”, “topos oratos”, “topos noêtos”, et aussi “apeiron” et “peras”.

Born in Poissy in 1977, Alexandra Michalewski holds the Agrégation of Philosophy (2000), and is a former student of the École Normale Supérieure (Paris-Ulm 1998). After completing her PhD in philosophy, entitled The Causality of Forms in the Philosophy of Plotinus, she became a postdoctoral researcher at the CNRS. In 2011, she was in residence at the University of Cologne as postdoctoral fellow of the Alexander von Humboldt Foundation. From 2012 to 2015, she was a postdoctoral researcher (FRS-FNRS) at the University of Liège (Belgium), where she taught regularly. She has been Research Fellow (CR1) at the CNRS since 2015.
Her work focuses on the cosmology and metaphysics of the Platonic tradition, from the imperial era to late Antiquity. Since 2009, her research has been conducted in close collaboration with several Belgian universities, especially with the researchers at the De Wulf-Mansion Centre for Ancient, Medieval and Renaissance Philosophy at KU Leuven, where she is an associate member. She has also organized workshops and conferences in Paris, Leuven and Liège, concerning the so-called ‘theory’ of Forms and the reception of the Platonic theory of cosmological principles (La puissance de l’intelligible. La théorie plotinienne des Formes au miroir de l’héritage médioplatonicien, Leuven, University Press, 2014, Prix Desrousseaux de l'Association des Études Grecques. Co-edited with P. d'Hoine : Les Formes platoniciennes dans l’Antiquité tardive, Études Platoniciennes VIII, Paris, Belles Lettres, 2011).
One of the main themes of Alexandra Michalewski’s research is the interplay between Aristotelianism and Platonism, from the beginnings of the imperial era to late Antiquity especially regarding (1) the question of the nature and causality of intelligible Forms and (2) the receptions of Aristotelianism in the context of the emergence of Platonic commentarism.
She is currently preparing a new edition and translation of the fragments of the Middle Platonist Atticus.
Co-Director with Pieter d'Hoine (DWMC-KU Leuven) of a funded research project (PICS, 2018-2021) : The theory of intelligible Forms in late Neoplatonism: translation and commentary of books Alpha to Gamma of Asclepius of Tralles’ Commentary on Aristotle’s Metaphysics.
