"For explanations of a universe that confuses him, [Man] seizes onto numerology, astrology, hysterical religions, and other fancy ways to go crazy. Having accepted such glorified nonsense, facts make no impression on him, even if at the cost of his own life. Joe, one of the hardest things to believe is the abysmal depth of human stupidity."
- Kettle Belly Baldwin in "Gulf" from Assignment in Eternity by Robert Heinlein
