Ma nuit chez Maud

Jean-Louis: Are you still a Marxist?

Vidal: Absolutely. For a Communist, Pascal's wager is very relevant today. Personally, I very much doubt that history has any meaning. Yet I wager that it has, so I'm in a Pascalian situation. Hypothesis A: Society and politics are meaningless. Hypothesis B: History has meaning. I'm not at all sure B is more likely to be true than A. More likely the reverse. Let's even suppose B has a 10% chance of being true and A has 80%. Nevertheless I have no choice but to opt for B, because only the hypothesis that history has meaning allows me to go on living. Suppose I bet on A, and B was true, despite the lesser odds. I'd have thrown away my life. So I must choose B to justify my life and actions. There's an 80% chance I'm wrong but that doesn't matter.

Jean-Louis: Mathematical hope. Potential gain divided by probability. With your hypothesis B, though the probability is slight, the possible gain is infinite. In your case, a meaning to life. In Pascal's, eternal salvation.

Vidal: It was Gorky, Lenin or maybe Mayakovsky who said about the Russian revolution that the situation forced them to choose the one chance in a thousand. Because hope became infinitely greater if you took that chance than if you didn't take it.
