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.
Medievalism Medievalism is the system of belief and practice characteristic of the Middle Ages, or devotion to elements of that period, which has been expressed in areas such as architecture, literature, music, art, philosophy, scholarship, and various vehicles of popular culture. Since the eighteenth century, a variety of movements have used the medieval period as a model or inspiration for creative activity, including Romanticism, the Gothic revival, the Pre-Raphaelite and arts and crafts movements and neo-medievalism (a term often used interchangeably with medievalism). The words "medievalism" and "Medieval" are both first recorded in the nineteenth century. "Medieval" is derived from Latin "medium aevum" (middle of the ages).
