For this purpose, Aristotle's book \u201cOn the Heaven,\u201d in which he explained the eternity, uniqueness and movement of the universe, occupied a place of special importance. But the Aristotelian philosopher had a hard time holding his own in the face of contradictions within the book and with respect to Aristotle's later works. In his early Compendium, later Paraphrase, and final Long Commentary of De Caelo, Ibn Rushd continued the efforts of the Hellenistic commentators in order to integrate all the elements of his doctrine into a unified system, to harmonize his early cosmology with his later Metaphysics \u2013 the early doctrine of natural movement of the elements, and of the self-moving star-souls (a Platonic element), with the doctrine of potency and actuality and the theory of the First Mover \u2013 and to uphold his models of homocentric planetary spheres against the mathematical paradigm of Ptolemaic astronomy. By insisting throughout on demonstrative arguments based on rational principles, he asserted the philosophers' claim to irrefutable truth.","btype":3,"date":"1995","language":"English","online_url":"","doi_url":"https:\/\/doi.org\/10.1017\/S0957423900001934","ti_url":"","categories":[{"id":21,"category_name":"Aristotle","link":"bib?categories[]=Aristotle"},{"id":23,"category_name":"Commentary","link":"bib?categories[]=Commentary"},{"id":66,"category_name":"De caelo","link":"bib?categories[]=De caelo"},{"id":19,"category_name":"Cosmology","link":"bib?categories[]=Cosmology"},{"id":31,"category_name":"Metaphysics","link":"bib?categories[]=Metaphysics"}],"authors":[{"id":203,"full_name":"Gerhard Endress","role":1}],"works":[],"republication_of":null,"translation_of":null,"new_edition_of":null,"book":null,"booksection":null,"article":{"id":5787,"journal_id":null,"journal_name":"Arabic Sciences and Philosophy","volume":"5","issue":"1","pages":"9 - 49"}},"sort":["Averroes' De Caelo Ibn Rushd's Cosmology in his Commentaries on Aristotle's On the Heavens"]}
