Aristotelianism Aristotelianism ( ) is a tradition of philosophy that takes its defining inspiration from the work of Aristotle. This school of thought is in the modern sense of philosophy, covering existence, ethics, mind and related subjects. In Aristotle's time, philosophy included natural philosophy, which was replaced by modern science during the Scientific Revolution. The works of Aristotle were initially defended by the members of the Peripatetic school and later on by the Neoplatonists, who produced many commentaries on Aristotle's writings. In the Islamic Golden Age, Ibn Sina and Ibn Rushd translated the works of Aristotle into Arabic and under philosophers such as Al-Kindi, Al-Farabi, Avicenna and Averroes, Aristotelianism became a major part of early Islamic philosophy.
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.
