The Cistercian foundation which was the home of the Jansenist sect in France. In 1662 Antoine Arnauld and Pierre Nicole (1625–95), possibly with the help of Pascal, published La Logique, ou l’art de penser, often called The Port-Royal Logic, which they revised many times between then and 1685, and which eventually became a standard text-book for logic and critical thinking. It showed an impatience with traditional Aristotelian or scholastic logic, and sympathizes with modern movements of thought, in particular the methodology of ‘clear and distinct’ ideas of Descartes, and his geometric and rationalistic approach to the investigation of nature. As Jansenists, the members of Port-Royal believed in predestination, and the utter impossibility of words, prayers, or deeds altering one’s preordained fate of going to heaven or hell. Perhaps unsurprisingly the historian and critic Sainte-Beuve (1804–69) lost his faith while writing the history of the monastery.
