Thomas Paine was an influential 18th-century writer of essays and pamphlets. Among them were "The Age of Reason," regarding the place of religion in society; "Rights of Man," a piece defending the French Revolution; and "Common Sense," which was published during the American Revolution. "Common Sense," Paine's most influential piece, brought his ideas to a vast audience, swaying (the otherwise undecided) public opinion to the view that independence from the British was a necessity.
