"Pensées" is a collection of thoughts and reflections by the French philosopher and mathematician Blaise Pascal. Written in the 17th century, it explores themes such as faith, reason, and the human condition. Pascal intended it as a defense of Christianity, addressing the struggles of belief and the nature of existence. The work is notable for its fragmented style, consisting of notes and essays rather than a continuous narrative. It delves into concepts like Pascal's Wager, which argues for belief in God as a rational choice. "Pensées" remains influential in philosophy and theology, prompting discussions on faith and rationality.
