Antoine Arnauld
Antoine Arnauld (French pronunciation: [ɑ̃twan aʁno]; 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.
Not to be confused with his father Antoine Arnauld (lawyer) or his nephew Antoine Arnauld (1616–1698).
