“Guard with jealous attention the public liberty. Suspect everyone who approaches that jewel. Unfortunately, nothing will preserve it but downright force. Whenever you give up that force, you are ruined…. The great object is that every man be armed. Everyone who is able might have a gun.” – Patrick Henry, Speech to the Virginia Ratifying Convention, June 5, 1778
“The Constitution shall never be construed to prevent the people of the United States who are peaceable citizens from keeping their own arms.” – Samuel Adams, Massachusetts Ratifying Convention, 1788
I ask who are the militia? They consist now of the whole people, except a few public officers.” – George Mason, Address to the Virginia Ratifying Convention, June 4, 1788
“The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes…. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.” – Thomas Jefferson, Commonplace Book (quoting 18th century criminologist Cesare Beccaria), 1774-1776
“No free man shall ever be debarred the use of arms.” – Thomas Jefferson, Virginia Constitution, Draft 1, 1776
