“Education is thus a most powerful ally of humanism, and every public school is a school of humanism. What can the theistic Sunday school, meeting for an hour once a week, and teaching only a fraction of the children, do to stem the tide of a five-day program of humanistic teachings?” — Charles Francis Potter

Potter was one of the original 34 signers of the first Humanist Manifesto in 1933. He also founded the First Humanist Society of New York, whose advisory board included fellow humanists Julian Huxley, John Dewey, Albert Einstein, and Thomas Mann.
