8318 Averroes           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Named for Averroes (1126-1198), whose Arabian name was Ibn Roschd Abdul Walid and who studied law and medicine in Córdoba. He brought together the philosophy of Aristotle, Islam and Christianity. Both Islam and the Christian church, especially Thomas Aquinas, condemned him. Most of his publications have been translated into Latin.
