Common Sense, the Crisis, & Other Writings from the American Revolution   Thomas Paine
Common Sense is the pamphlet that influenced pretty much everyone who helped bring about American independence and was read by hundreds of thousands of common people. Embarrassed to say I had not read it until now. Especially interesting to read The Crisis issues as I read about the events Paine, who was fighting with the colonial army at the time, discusses. One of the founding intellectual documents of the United States.
