  • Léo F. Laporte, ed. (1987). Simple Curiosity: Letters from Gaylord Simpson to His Family, 1921-1970. University of California Press. p. 16. ISBN 9780520057920. By his early teens, Simpson had given up being a Christian, although he had not formally declared himself an atheist. At college he began the gradual development of what might best be called positivistic agnosticism: a belief that the world could be known and explained by ordinary empirical observation without recourse to supernatural forces. Ultimate causation, he considered unknowable.
