Lettres provinciales, 1656-1657 (The Provincial Letters, 1657)
Pensées, 1670 (Monsieur Pascal’s Thoughts, Meditations, and Prayers, 1688; best known as Pensées)
Blaise Pascal (pahs-kahl), born on June 19, 1623, was a precocious child tutored at home in Clermont-Ferrand and later in Paris by his father. During Pascal’s boyhood his father displeased Cardinal Richelieu by objecting to the cardinal’s handling of some financial matters and had to go into temporary exile. The cardinal later relented and appointed Pascal’s father intendant of Rouen in 1639, a post he held for nine years. During the years in Rouen, Pascal became acquainted with Pierre Corneille, the famous dramatist. In 1646 the Pascal family became interested in Jansenism, although Blaise Pascal himself seems to have been at the time more interested in science than in religion. He had written a geometric treatise at the age of seventeen, and his first complete demonstration of the barometer in 1647 was only one of his many achievements in mathematics and physics.

In 1650 the Pascal family returned to Paris, where Pascal’s father died the following year. Jacqueline Pascal, a sister, joined a convent at Port Royal. During this period, Pascal continued his scientific experiments, but he also became very interested in theology and moral philosophy. In 1654 he underwent a mystical experience at the convent at Port Royal and a few months later retired from the world. He wrote his recollection of this mystical experience in a text called “The Memorial,” which he sewed into his clothing in order to have it with him at all times. “The Memorial” was found in his jacket after his death in 1662. During 1656 he came out of retirement briefly to defend Antoine Arnauld from an attack by the Jesuits, publishing a series of letters (The Provincial Letters).
Pascal continued to live a quiet, religious life within the walls of Port Royal until his death on August 19, 1662. Eight years later a committee of Jansenists, headed by the Duc de Roannez, Pascal’s friend, edited and published the Pensées, fragments salvaged from a projected but unfinished work to be called “Apologie de la religion catholique.” Pascal’s nephew Etienne Périer believed that the order in which these fragments were discovered after his uncle’s death made no sense, and he reorganized them in an order that seriously distorted Pascal’s intentions. Only nineteenth century and later editions, made from the original manuscripts, are trustworthy. It is both as a pioneer in science and mathematics and as an author that Pascal is an important figure in world history.
