  Telesio's cosmology puts an end to metaphysical explanations.  Telesio thought space to be absolute (DRN book I, ch. XXV–XXVIII), thus abolishing the Aristotelian notion of a bipartite cosmos divided into a sublunary world, in which generation and corruption take place, and a supralunary sphere with eternal regular movements. The existence of vacuum within space is admitted, but things are said to have a natural inclination to avoid empty space. In the cosmological chapters of book IV Telesio critizised the Aristotelian explanation of the movement of the cosmos by a transcendent telos, the God of Aristotle's metaphysics: the sky doesn't move because of a desire for a being more perfect than itself, but because it is its own nature to move and thus to sustain its own life (DRN book IV, ch. XXIV; Aristotle, Metaph. XII, ch. 6–7). Likewise, he rejected the idea that the motions of the subordinate spheres were caused by unmoved movers, the pure intelligences of the Aristotelian and Christian traditions, an assumption which he reprimanded to be obscure and incomprehensible even via imagination (Bondì 1018).
