" Some of the conclusions that I draw are very different from the ethical views most people hold today. That, however, is not a ground for dismissing them. If every proposal for reform in ethics that differed from accepted moral views had been rejected for that reason alone, we would still be torturing heretics, enslaving members of conquered races, and treating women as the property of their husbands. "
