Most diabolically, it had become—quite truly—a false religion. Founded by the former Baptist and Unitarian minister, Charles Francis Potter’s humanism went public at the very beginning of the fall of 1929 when he delivered a homily to 244 New Yorkers, having turned away well over 400 to meet the fire code. “Just as Protestantism was an offshoot of Roman Catholicism, and Liberalism, as represented by Unitarianism and Universalism, was born of Protestantism, so also Humanism has come forth from Unitarianism.” Blatantly taking the name of his new faith from Babbitt and More (whom he thought would be allies in his new religion) he asked his congregants to give up their primitive “deity obsession.” Only from man, Potter claimed, could one find true dignity. “Out of the heart of man have arisen all his noble impulses and aspirations.” Babbitt and More, horrified, condemned the new movement, and the scare almost certainly moved More toward Anglican orthodoxy. Potter, however, with the aid of the effete John Dewey and bizarre Harry Elmer Barnes, founded the American Humanist Association and issued the Humanist Manifesto in 1933. To be sure, the word “humanism” has never recovered.
