born 1401, Kues, Trierdied Aug. 11, 1464, Todi, Papal StatesGerman cardinal, mathematician, scientist, and philosopher.Ordained a priest in 1440, he was made a cardinal in Italy and became bishop there in 1450. In On Catholic Concordance (1433), he supported the supremacy of the general councils of the church over the papacy's authority (see conciliar movement). However, after witnessing the failure of the Council of Basel to unify the church or enact reform, he reversed his position and became an ardent supporter of the pope. Skilled in nearly every branch of learning, he anticipated the work of Nicolaus Copernicus by discerning a movement in the universe that did not centre on the Earth. He also carried out botanical experiments and collected ancient manuscripts. In his discourse On Learned Ignorance (1440), he described the learned man as one who is aware of his own ignorance.* * *
▪ Christian scholarGerman Nikolaus Von Cusa, Latin Nicolaus Cusanusborn 1401, Kues, Trierdied Aug. 11, 1464, Todi, Papal Statescardinal, mathematician, scholar, experimental scientist, and influential philosopher who stressed the incomplete nature of man's knowledge of God and of the universe.At the Council of Basel (Basel, Council of) in 1432, he gained recognition for his opposition to the candidate put forward by Pope Eugenius IV for the archbishopric of Trier. To his colleagues at the council he dedicated De concordantia catholica (1433; “On Catholic Concordance”), in which he expressed support for the supremacy of the general councils of the church over the authority of the papacy. In the same work he discussed the harmony of the church, drawing a pattern for priestly concord from his knowledge of the order of the heavens. By 1437, however, finding the council unsuccessful in preserving church unity and enacting needed reforms, Nicholas reversed his position and became one of Eugenius' most ardent followers. Ordained a priest about 1440, Cusa was made a cardinal in Brixen (Bressanone), Italy, by Pope Nicholas V and in 1450 was elevated to bishop there. For two years Cusa served as Nicholas' legate to Germany, after which he began to serve full-time as bishop of Brixen.A model of the “Renaissance man” because of his disciplined and varied learning, Cusa was skilled in theology, mathematics, philosophy, science, and the arts. In De docta ignorantia (1440; “On Learned Ignorance”) he described the learned man as one who is aware of his own ignorance. In this and other works he typically borrowed symbols from geometry to demonstrate his points, as in his comparison of man's search for truth to the task of converting a square into a circle.Among Cusa's other interests were diagnostic medicine and applied science. He emphasized knowledge through experimentation and anticipated the work of the astronomer Copernicus by discerning a movement in the universe that did not centre in the Earth, although the Earth contributed to that movement. Cusa's study of plant growth, from which he concluded that plants absorb nourishment from the air, was the first modern formal experiment in biology and the first proof that air has weight. Numerous other developments, including a map of Europe, can also be traced to Cusa. A manuscript collector who recovered a dozen lost comedies by the Roman writer Plautus, he left an extensive library that remains a centre of scholarly activity in the hospital he founded and completed at his birthplace in 1458.Additional ReadingH.
