Pascal and the Ultimate Wager

I admit I've not been much of a reader of Pascal - too old, too dry, too... certainly his book, Pensees, never entered my head as a candidate for a book report in high school or university. But, I must be getting older (or, old). He's an interesting philosopher/theologian. One of his more curious arguments is known as the argument of the wager. God either is or isn't. and we we must therefore lay odds (wager) for or against Him.

• If I wager for and God is — infinite gain;
• If I wager for and God is not — no loss.
• If I wager against and God is — infinite loss;
• If I wager against and God is not — neither loss nor gain.
