Part of the rationalist ethos is binding yourself emotionally to an absolutely lawful reductionistic universe - a universe containing no ontologically basic mental things such as souls or magic and pouring all your hope and all your care into that merely real universe and its possibilities, without disappointment.

There are branched versions of you that are dying of cancer, and not signed up for cryonics, and it's too late for them to get life insurance.
