Common Sense was a pamphlet written by Thomas Paine. It was first published anonymously on January 10, 1776, during the American Revolution. Common Sense presented the American colonists with an 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.[1] Historian Gordon S. Wood described Common Sense as, “the most incendiary and popular pamphlet of the entire revolutionary era.”[2]

I thought this was interesting reading and it does help paint the picture of some of the reasons why it was a good idea for the American colonies to seek independences from Britian.
