Benedict Pereira (also Pereyra, Benet Perera, Benet Pererius) (March 4, 1536 – 6 March 1610) was a Spanish Jesuit philosopher, theologian, and exegete. Life Pereira was born at Ruzafa, near Valencia, in Spain. He entered the Society of Jesus in 1552 and taught successively literature, philosophy, theology, and sacred scripture in Rome, where he died. Works He published eight works, and left a vast deal of manuscript. (Sommervogel, infra, mentions twelve sets.) His main philosophical work is De communibus omnium rerum naturalium principiis et affectionibus libri quindecim (Rome, 1576). The main difficulties of the Book of Genesis are met in Commentariorum et disputationum in Genesim tomi quattuor (Rome, 1591–1599). This is a mine of information in regard to the Deluge, Noah's Ark, the Tower of Babel, etc., and was highly rated by Richard Simon (Histoire critique du Vieux Testament, III, xii). The "Commentariorum in Danielem prophetam libri sexdecim" (Rome, 1587) are much less diffuse. Other writings published by Pereira were five volumes of exegetical dissertations on: "Exodus", 137 dissertations (Ingolstadt, 1601); "The Epistle to the Romans", 188 dissertations (Ingolstadt, 1603); "The Apocalypse", 183 dissertations (Lyons, 1606); "The Gospel of St. John", 214 dissertations on the first nine chapters (Lyons, 1608); 144 dissertations on five following chapters (Lyons, 1610). To the fourth volume of the dissertations is appended a work of twenty-three dissertations to show that Mohammed was not the Antichrist, of the Apocalypse and of Daniel. Debate against Clavius Pereira was an outspoken opponent of Christopher Clavius at the Collegio Romano. The debate concerned the nature of mathematics. Pereira argued that mathematical demonstrations point to complex relations between numbers, lines, figures, etc., but lack the logical force of a demonstration from true causes or the essence of things. Furthermore, mathematics does not have a true subject matter; it merely draws connections between different properties (Alexander, p. 69). Clavius responded in "Prolegomena" that the subject of mathematics is matter itself, since all mathematics is "immersed" in matter. The debate had broad ramifications with regard to inclusion of mathematics as a basic subject in the Jesuit curriculum.
