Overview
Port-Royal-des-Champs was an abbey of Cistercian nuns in Magny-les-Hameaux, in the Vallée de Chevreuse southwest of Paris that launched a number of culturally important institutions.
History
The abbey was established in 1204, but became famous when its discipline was reformed in 1609 by its abbess, Mother Marie Angelique Arnauld (1591-1661). The Arnauld family became its patrons and the abbey's subsequent history was directed by a number of the members of that family. In 1625 most of the nuns moved to a new Port-Royal in Paris, which subsequently became Port-Royal de Paris (or, more commonly, Port-Royal) while the older one was known as Port-Royal des Champs ("Port-Royal of the fields").
At the original site, several schools were founded, which became known as the Petites écoles de Port-Royal ("Little Schools of Port-Royal"). These schools became famous for the high quality of the education they gave. Playwright Jean Racine was a product of Port-Royal education. In 1634 Jean du Vergier de Hauranne, Abbé de Saint-Cyran, became spiritual director of the abbey; he was a companion of Jansenius and the implementer of Jansenism in France. From that point forward, the abbeys and schools of Port-Royal became intimately associated with that school of theology.
La logique, ou l'art de penser, the Logique de Port-Royal, was an important textbook on logic first published anonymously in 1662 by Antoine Arnauld and Pierre Nicole, two prominent members of the Jansenist movement; Blaise Pascal likely contributed considerable portions of the text. As it was written in the vernacular, it became quite popular and was in use, as an exemplar of traditional term logic, into the twentieth century, introducing the reader to logic, and exhibiting strong Cartesian elements in its metaphysics and epistemology (Arnauld having been one of the main philosophers whose objections were published, with replies, in Descartes' Meditations on First Philosophy).
