Unicité du monde et figures de la temporalité chez Marsile Ficin avec introduction, présentation, établissement critique du text, traduction, notes et commentaire des Argumenta Marsilii Ficinii in Rempublicam Platonis

The thesis studies and highlights the central theme of temporality in Marsilio Ficino’s philosophy which is a thought crossed by the figures of time that are tradition, revelation and hope. The philosophy of Ficino, which is both a coherent and united thought, is not a system but it is rather the expression of a dynamic, specific to the Renaissance thought. In this study, the forms of the temporality and the unicity of the world are examined through the critical analysis of Marsilio Ficino's Commentary on the Republic of Plato which, unlike the political and ethical themes specific to the platonic dialogue, is expressly metaphysical and theological because the figures of temporality are conceived as so many metaphysical points of view from which are contemplated the world and the beings composing it. As this text did not benefit from a modern French translation, the thesis fills a gap in ficinian studies by proposing for the first time a French translation of the Argumenta in Rempublicam Platonis is proposed for the first time and, this French version, which is based on the critical establishment of the text, includes a notice, additional notes and the possibility of referring to the various sources on which this work is based. Finally, the thesis exposes a strictly ficinian definition of temporality as a spiritual and human reality by dealing with the question of the genesis and genealogy of temporal concepts and showing its cosmological implication.
