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.
Álvaro of Córdoba Paulus Alvarus (also known as Paul Alvarus, Paul Albar, Alvaró de Córdoba), c. 800 – 861 CE, was a ninth-century Mozarab scholar, poet, and theologian who lived in Southern Iberia during the period of Muslim rule. He is most notable for his writings around the time of a rising high civilization of Islam, owing to the Caliph's efforts. He also wrote the "Vita Eulogii" (‘The Life of Eulogius’), a biography of his close friend and fellow theologian Saint Eulogius of Cordoba. Although Christians living in Córdoba and the rest of Muslim Iberia during his time lived under relative religious freedom, Alvarus was amongst the Christians who perceived the many restrictions on the practice of their faith to be unacceptable persecution; they regarded with extreme scorn Christians who participated in the Muslim government, converted to Islam, or simply concealed their true beliefs. As a result of these religious tensions Alvarus’s writings are characterized by contempt of all things Muslim and he considered Muhammed to have been the precursor to the Antichrist.
