Treatise On Toleration by Voltaire

à l'occasion de la mort de Jean Calas

Written in the wake of the Calas affair, this polemic denounces religious fanaticism and judicial cruelty while urging compassion, reason, and freedom of conscience. It argues that no creed justifies persecution, calls for civil moderation and legal reform, and champions universal tolerance as essential to social harmony. Drawing on historical examples and moral appeals, it promotes a humane, rational order over dogma and sectarian hatred.
