The Age of Reason: Complete: Part I and II

The Age of Reason; Being an Investigation of True and Fabulous Theology is an influential work written by English and American political activist Thomas Paine. It follows in the tradition of eighteenth-century British deism, and challenges institutionalized religion and the legitimacy of the Bible. Originally distributed as unbound pamphlets, it was published in three parts in 1794, 1795, and 1807. It was a best-seller in the United States, where it caused a short-lived deistic revival. British audiences, however, fearing increased political radicalism as a result of the French Revolution, received it with more hostility. The Age of Reason presents common deistic arguments; for example, it highlights what Paine saw as corruption of the Christian Church and criticizes its efforts to acquire political power. Paine advocates reason in the place of revelation, leading him to reject miracles and to view the Bible as "an ordinary piece of literature rather than as a divinely inspired text". It promotes natural religion and argues for the existence of a creator-God.

English-born Thomas Paine left behind hearth and home for adventures on the high seas at nineteen. Upon returning to shore, he became a tax officer, and it was this job that inspired him to write The Case of the Officers of Excise in 1772. Paine then immigrated to Philadelphia, and in 1776 he published Common Sense, a defense of American independence from England. After returning to Europe, Paine wrote his famous Rights of Man as a response to criticism of the French Revolution. He was subsequently labeled as an outlaw, leading him to flee to France where he joined the National Convention. However, in 1793 Paine was imprisoned, and during this time he wrote the first part of The Age of Reason, an anti-church text which would go on to be his most famous work. After his release, Paine returned to America where he passed away in 1809.
