Pensées

The Pensées (Thoughts) is a collection of fragments written by the French 17th-century philosopher and mathematician Blaise Pascal. Pascal's religious conversion led him into a life of asceticism, and the Pensées was in many ways his life's work. It represented Pascal's defense of the Christian religion, and the concept of "Pascal's wager" stems from a portion of this work.

Blaise Pascal (19 June 1623 - 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer.
