Eric Rohmer’s brainy dramatization of Blaise Pascal’s wager, mingled with reflections on the relationship between mathematics and morality, and with a little Mozart thrown in. Memorably, part-ironically, most luminously set on a snowy Christmas Eve. Festive at the margins, striving through and through, and love and mercy at the core.
(Pascal’s wager is here, in section 233: http://bit.ly/1JRFCHH. The rest of the link leads us beautifully up to and away from the actual famous statement. It’s all really good. Here’s a summary: http://stanford.io/1Ghe7Zc.)
