Nicholas of Cusa (redirected from Cusa)

Nicholas of Cusa (Nicolaus Cusanus), 1401?–1464, German humanist, scientist, statesman, and philosopher, from 1448 cardinal of the Roman Catholic Church. The son of a fisherman, Nicholas was educated at Deventer, Heidelberg, Padua, Rome, and Cologne. He became bishop of Brixon (Bressanone) in 1450 and instituted widespread, though temporary, reforms of the monasteries. As papal legate he traveled throughout Europe preaching and negotiating diplomatic affairs for the Holy See. Nicholas' greatest achievements were in science and philosophy. His researches and writings formed major advances in Renaissance mathematics, astronomy, and mysticism. He held, before the time of Copernicus and Newton, that the nearly spherical earth revolves on its axis about the sun and that the stars are other worlds. He described the Gregorian calendar reform in detail, before it occurred. In mathematics Nicholas propounded significant concepts of the infinitesimal and contributed to modern relativity theory. His mystical religious philosophy was set forth in his essays De Docta Ignorantia [of learned ignorance] (1440, tr. 1954), De Conjuncturis Libri Duo, and De Visio Dei [vision of God] (1453, tr. 1928). It anticipated the direction of growth of Renaissance conjecture concerning the nature of man and his relationship to the cosmos.

Nicholas of Cusa

(born 1401, Kues, Trier—died Aug. 11, 1464, Todi, Papal States) German 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.
