Common Sense is a pamphlet written by Thomas Paine. It was first published anonymously on January 10, 1776, during the American Revolution. Common Sense, signed "Written by an Englishman", became an immediate success. In relation to the population of the Colonies at that time, it had the largest sale and circulation of any book in American history. Common Sense presented the American colonists with a powerful argument for independence from British rule at a time when the question of independence was still undecided. Paine wrote and reasoned in a style that common people understood; forgoing the philosophy and Latin references used by Enlightenment era writers, Paine structured Common Sense like a sermon and relied on Biblical references to make his case to the people. Historian Gordon S. Wood described Common Sense as, "the most incendiary and popular pamphlet of the entire revolutionary era".
"These are the times that try men's souls," begins Thomas Paine's first Crisis paper, the impassioned pamphlet that helped ignite the American Revolution. Published in Philadelphia in January of 1776, Common Sense sold 150,000 copies almost immediately. A powerful piece of propaganda, it attacked the idea of a hereditary monarchy, dismissed the chance for reconciliation with England, and outlined the economic benefits of independence while espousing equality of rights among citizens. Paine fanned a flame that was already burning, but many historians argue that his work unified dissenting voices and persuaded patriots that the American Revolution was not only necessary, but an epochal step in world history.
