The end result, says Boehm, was a process sometimes called “self-domestication.” Just as animal breeders can create tamer, gentler creatures by selectively breeding for those traits, our ancestors began to selectively breed themselves (unintentionally) for the ability to construct shared moral matrices and then live cooperatively within them. The Liberty/oppression foundation, I propose, evolved in response to the adaptive challenge of living in small groups with individuals who would, if given the chance, dominate, bully, and constrain others.
