‘How should the agnostic live?’ compares the effects of agnosticism in science and morality. It argues that a religious life is possible for the agnostic. The argument for faith known as Pascal's Wager is explained. For Pascal himself, faith was a matter of passionate commitment and total belief. Science can be done without emotion; religion cannot. Our engagement in fiction is compared to our engagement in religious ritual. Perhaps, in order for us to immerse ourselves entirely, we have to forget that it is a fiction that we are engaging in. Belief in God is a belief that there is an explanation, even if we don't fully understand that explanation.
