Résumé
The Aristotelian universe is limited, heterogeneous and hierarchical. It is limited as enclosed in a sphere, heterogeneous because it has areas that are clearly distinguishable from each other, and hierarchical because the various spherical layers of the Whole (tò pân) enjoy gradually decreasing degrees of ontological plenitude. Thus, the sublunary area, realm of generation (génesis) and corruption (phthorá) of substances, is characterized by the concentricity with which the four elements (fire, air, water, earth) that compose it are arranged. The superlunary area, for its part, has maximum stability. In its domain nothing is corruptible, while the celestial bodies are composed of ether and surrounded by ether, a very subtle element of regular behaviour. Like in a perfect flow, the spherical celestial layers are in turn moved in circle, according to Aristotle, by intelligible unmoved movers (incorruptible, eternal, immaterial and divine-pure substances), a crucial point that deserves special attention to understand the metaphysical framework of Aristotle´s cosmology. The conference will present the main features of Aristotle´s cosmos, and explain the reasons why Aristotle posed fifty-five unmoved movers to grant the eternal equilibrium of the sublunary phýsis, that exhibits, in all its manifestations, a circular motion that mirrors the dominant eternal motion of heavens.
