Pascal's Wager (Substantive 2022 Revision)

Abstract

“Pascal’s Wager” is the name given to an argument due to Blaise Pascal for believing, or for at least taking steps to believe, in God. The name is somewhat misleading, for in a single section of his Pensées, Pascal apparently presents four such arguments, each of which might be called a ‘wager’—it is only the third of these that is traditionally referred to as “Pascal’s Wager”. We find in it the extraordinary confluence of several important strands of thought: the justification of theism; probability theory and decision theory, used here for almost the first time in history; pragmatism; voluntarism (the thesis that belief is a matter of the will); and the use of the concept of infinity.
