Adelard of BathAdelard of Bath (Adelardus Bathensis; 1080? - 1142–1152?) was a 12th-century English natural philosopher. He is known both for his original works and for translating many important Greek scientific works of astrology, astronomy, philosophy, alchemy and mathematics into Latin from Arabic versions, which were then introduced to Western Europe. The oldest surviving Latin translation of Euclid's Elements is a 12th-century translation by Adelard from an Arabic version. He is known as one of the first to introduce the Arabic numeral system to Europe.
Robert GrossetesteRobert Grosseteste (ˈgroʊstɛst ; Robertus Grosseteste; 1168 - 8 or 9 October 1253), also known as Robert Greathead or Robert of Lincoln, was an English statesman, scholastic philosopher, theologian, scientist and Bishop of Lincoln. He was born of humble parents in Suffolk (according to the early 14th-century chronicler Nicholas Trevet), but the associations with the village of Stradbroke is a post-medieval tradition. Upon his death, he was revered as a saint in England, but attempts to procure a formal canonisation failed.
BonaventureBonaventure, OFM (ˈbɒnəvɛntʃər,_ˌbɒnəˈvɛntʃər ; Bonaventura da Bagnoregio ˌbɔnavenˈtuːra da (b)baɲɲoˈrɛːdʒo; Bonaventura de Balneoregio; born Giovanni di Fidanza; 1221 – 15 July 1274) was an Italian Catholic Franciscan bishop, cardinal, scholastic theologian and philosopher. The seventh Minister General of the Order of Friars Minor, he also served for a time as Bishop of Albano. He was canonised on 14 April 1482 by Pope Sixtus IV and declared a Doctor of the Church in 1588 by Pope Sixtus V.
Logica novaIn the history of logic, the term logica nova (Latin, meaning "new logic") refers to a subdivision of the logical tradition of Western Europe, as it existed around the middle of the twelfth century. The Logica vetus ("old logic") referred to works of Aristotle that had long been known and studied in the Latin West, whereas the Logica nova referred to forms of logic derived from Aristotle's works which had been unavailable until they were translated by James of Venice in the 12th century.
IsagogeThe Isagoge (Εἰσαγωγή, Eisagōgḗ; 'aisəgo:dZi:) or "Introduction" to Aristotle's "Categories", written by Porphyry in Greek and translated into Latin by Boethius, was the standard textbook on logic for at least a millennium after his death. It was composed by Porphyry in Sicily during the years 268–270, and sent to Chrysaorium, according to all the ancient commentators Ammonius, Elias, and David.
Renaissance of the 12th centuryThe Renaissance of the 12th century was a period of many changes at the outset of the High Middle Ages. It included social, political and economic transformations, and an intellectual revitalization of Western Europe with strong philosophical and scientific roots. These changes paved the way for later achievements such as the literary and artistic movement of the Italian Renaissance in the 15th century and the scientific developments of the 17th century.
Unmoved moverThe unmoved mover (ho ou kinoúmenon kineî) or prime mover (primum movens) is a concept advanced by Aristotle as a primary cause (or first uncaused cause) or "mover" of all the motion in the universe. As is implicit in the name, the moves other things, but is not itself moved by any prior action. In Book 12 (Λ) of his Metaphysics, Aristotle describes the unmoved mover as being perfectly beautiful, indivisible, and contemplating only the perfect contemplation: self-contemplation. He equates this concept also with the active intellect.
Thomas BradwardineThomas Bradwardine (c. 1300 – 26 August 1349) was an English cleric, scholar, mathematician, physicist, courtier and, very briefly, Archbishop of Canterbury. As a celebrated scholastic philosopher and doctor of theology, he is often called Doctor Profundus (medieval epithet, meaning "the Profound Doctor"). Bradwardine was born in Sussex either at Hartfield or at Chichester, where his family was settled, members of the smaller gentry or burghers. Sources vary about Bradwardine's early life before receiving his degree in 1321.
Latin translations of the 12th centuryLatin translations of the 12th century were spurred by a major search by European scholars for new learning unavailable in western Europe at the time; their search led them to areas of southern Europe, particularly in central Spain and Sicily, which recently had come under Christian rule following their reconquest in the late 11th century. These areas had been under Muslim rule for a considerable time, and still had substantial Arabic-speaking populations to support their search.
Active intellectIn medieval philosophy, the active intellect (Latin: intellectus agens; also translated as agent intellect, active intelligence, active reason, or productive intellect) is the formal (morphe) aspect of the intellect (nous), according to the Aristotelian theory of hylomorphism. The nature of the active intellect was a major theme of late classical and medieval philosophy. Various thinkers sought to reconcile their commitment to Aristotle's account of the body and soul to their own theological commitments.
