Antoine ArnauldAntoine Arnauld (6 February 1612 - 8 August 1694) was a French Catholic theologian, philosopher and mathematician. He was one of the leading intellectuals of the Jansenist group of Port-Royal and had a very thorough knowledge of patristics. Contemporaries called him le Grand to distinguish him from his father. Antoine Arnauld was born in Paris to the Arnauld family. The twentieth and youngest child of the original Antoine Arnauld, he was originally intended for the bar, but decided instead to study theology at the Sorbonne.
Blaise PascalBlaise Pascal (pæˈskæl , alsoUK-ˈskɑːl,'paesk@l,-skæl , USpɑːˈskɑːl ; blɛz paskal; 19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer. Pascal was a child prodigy who was educated by his father, a tax collector in Rouen. His earliest mathematical work was on conic sections; he wrote a significant treatise on the subject of projective geometry at the age of 16. He later corresponded with Pierre de Fermat on probability theory, strongly influencing the development of modern economics and social science.
Baruch SpinozaBaruch (de) Spinoza (24 November 1632 – 21 February 1677) was a philosopher of Portuguese-Jewish origin, born in Amsterdam, the Dutch Republic, and mostly known under the Latinized pen name Benedictus de Spinoza. One of the foremost and seminal thinkers of the Enlightenment, modern biblical criticism, and 17th-century Rationalism, including modern conceptions of the self and the universe, he came to be considered "one of the most important philosophers—and certainly the most radical—of the early modern period".
René DescartesRené Descartes (deɪˈkɑːrt or UKˈdeɪkɑːrt; ʁəne dekaʁt; Latinized: Renatus Cartesius; 31 March 1596 – 11 February 1650) was a French philosopher, scientist, and mathematician, widely considered a seminal figure in the emergence of modern philosophy and science. Mathematics was central to his method of inquiry, and he connected the previously separate fields of geometry and algebra into analytic geometry. Descartes spent much of his working life in the Dutch Republic, initially serving the Dutch States Army, later becoming a central intellectual of the Dutch Golden Age.
