You can't argue the pedigree of a 17th-century philosopher whose contributions in science and mathematics still influence the way we live and think today. Blaise Pascal was a genius by any definition. Moreover, he was a genius who experienced an intense, near-mystical conversion to Christianity and began applying his intellect to theology. A selection from his masterwork, Pensées, Pascal Foundations of the Christian Religion is more than a defense of the faith. It remains some of the finest literature in the Western canon.
