“Every one of the Leavers' ways came into being by evolution, by a process of testing that began even before people had a word for it. No one said, 'Okay, let's form a committee to write up a set of laws for us to follow.' None of these cultures were inventions. But that's what all our lawgivers give us--inventions. Contrivances. Not things that have proved out over thousands of generations, but rather arbitrary pronouncements about the one right way to live.”
