When governments fear the people, there is liberty. When the people fear the government, there is tyranny. The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
—Thomas Jefferson, author of the U.S. Declaration of Independence
A general dissolution of principles and manners will more surely overthrow the liberties of America than the whole force of the common enemy. While the people are virtuous they cannot be subdued; but when once they lose their virtue then will be ready to surrender their liberties to the first external or internal invader.
—Samuel Adams, 1779
