Maybe our forebears felt by instinct that there were gods or that there was one true God. This instinct formed itself into religion, or several religions. […] Those deep instincts that goodness is not something we invented for ourselves, that it is "there" independent of our ability to attain it, irrespective of how many people deny it. You could have the whole Third Reich with all its power and all its deadly attractiveness designed to tell you that it was a good thing to send a child to a gas oven; but every single person on this planet would "know" that it was evil. That's what makes me hold on. We did not invent the rules. (Part Two, Chapter Twenty)
