Thomas Paine’s The Age of Reason was a clarion call for a world ruled by reason rather than religious dogma. He attacked the foundations of organized religion, challenging the divine authority claimed by Jewish, Christian, and Islamic traditions. He exposed the contradictions, absurdities, and moral failures of the Bible, denouncing both the Old and New Testaments as human-made myths. He extended his critique to Islam, the dominant faith of the Ottoman Empire, rejecting its supernatural claims and its authoritarian structure.
 
The Age of Reason was a significant leap forward in human thought, marking the beginning of a new Enlightenment. It was a fearless declaration of intellectual independence, calling for a world in which faith was replaced by reason, superstition by science, and tyranny by freedom.
