Blaise Pascal (1623-62) had proven his genius as a mathematician and physicist, inventing the first computer and wristwatch, advancing our understanding of air density, vacuums, hydraulics, calculus, and probability, and designing the first public transit system in Paris.[1] But his true genius was in insisting that there’s more to reality than reason reveals. After a definitive experience of grace, he was thoroughly converted to the faith and began writing in its defense, most notably the Pensées, in which he suggests that, since we cannot know through reason whether God exists, we should bet on belief. This Wager is not based on dumb luck but on the reason deferentially listening to God, through whom we can understand the true condition of man and the solution found in the gospel as attested by prophecies, miracles, and martyrdom. All of this, taken together, makes Pascal’s Wager undeniably reasonable.
