freethinkers, those who arrive at conclusions, particularly in questions of religion, by employing the rules of reason while rejecting supernatural authority or ecclesiastical tradition. The freethinkers believe that independence of thought from such authority leads all men to essentially identical conclusions concerning morality and religion. The name came into general use in the 18th cent. after the publication (1713) of Anthony Collins's Discourse of Freethinking Occasioned by the Rise and Growth of a Sect Called Freethinkers. The movement took different forms in different countries. In England it was intimately connected with deism but did not break completely with traditional Christianity. It took a more radical form in France. Voltaire renounced all connection with Christianity, and the Encyclopedists broke with religion altogether. Freethinking also has an important social side and influenced the philosophies of the Freemasons and, in France, the Culte de l'Être Suprême. In the United States the organizations established to further freethinking include the American Rationalist Association, the American Secular Union, and the Freethinkers of America. The International Order for Ethics and Culture, organized at Bern in 1908, is designed to investigate the ethical factors in society without theological or metaphysical bias.
