Averroes was a philosopher under which philosophical movements  such as Aristotelianism and the 13th-century philosophical movement  came into play in what other religions beside Islam?
Averroes Ibn Rushd (Arabic: ‎ ‎ ; 14 April 1126 – 10 December 1198), full name (Arabic: أبو الوليد محمد ابن احمد ابن رشد‎ , "ʾAbū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rushd " ‎ ), often Latinized as Averroes ( ), was a medieval Andalusian polymath. He wrote on logic, Aristotelian and Islamic philosophy, theology, the Maliki school of Islamic jurisprudence, psychology, political and Andalusian classical music theory, geography, mathematics, and the mediæval sciences of medicine, astronomy, physics, and celestial mechanics. Ibn Rushd was born in Córdoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco. His body was interred in his family tomb at Córdoba. The 13th-century philosophical movement in Latin Christian and Jewish tradition based on Ibn Rushd's work is called Averroism.
Xenocrates Xenocrates ( ; Greek: Ξενοκράτης ; c. 396/5314/3 BC ) of Chalcedon was a Greek philosopher, mathematician, and leader (scholarch) of the Platonic Academy from 339/8 to 314/3 BC. His teachings followed those of Plato, which he attempted to define more closely, often with mathematical elements. He distinguished three forms of being: the sensible, the intelligible, and a third compounded of the two, to which correspond respectively, sense, intellect and opinion. Unity and duality he considered to be gods which rule the universe, and the soul is a self-moving number. God pervades all things, and there are daemonical powers, intermediate between the divine and the mortal, which consist in conditions of the soul. He held that mathematical objects and the Platonic Ideas are identical, unlike Plato who distinguished them. In ethics, he taught that virtue produces happiness, but that external goods can minister to it and enable it to effect its purpose.
