The Militia is composed of free Citizens. There is therefore no danger of their making use of their power to the destruction of their own rights, or suffering others to invade them.
Samuel Adams, Writings, pg. 251
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
The police of a state should never be stronger or better armed than the citizenry. An armed citizenry, willing to fight, is the foundation of civil freedom.
Robert A. Heinlein, Chapter 9, “When we die, do we die all over?”, p. 97
A free people ought not only to be armed, but disciplined…
George Washington, First Annual Address, to both House of Congress, January 8, 1790
No free man shall ever be debarred the use of arms
Thomas Jefferson, Virginia Constitution, Draft 1, 1776
A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be your constant companion of your walks.
Thomas Jefferson, letter to Peter Carr, August 19, 1785
The Constitution of most of our states (and of the United States) assert that all power is inherent in the people; that they may exercise it by themselves; that it is their right and duty to be at all times armed.
Thomas Jefferson, letter to to John Cartwright, 5 June 1824
On every occasion [of Constitutional interpretation] let us carry ourselves back to the time when the Constitution was adopted, recollect the spirit manifested in the debates, and instead of trying [to force] what meaning may be squeezed out of the text, or invented against it, [instead let us] conform to the probable one in which it was passed.
Thomas Jefferson, letter to William Johnson, 12 June 1823
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
Besides the advantage of being armed, which the Americans possess over the people of almost every other nation, the existence of subordinate governments, to which the people are attached, and by which the militia officers are appointed, forms a barrier against the enterprises of ambition, more insurmountable than any which a simple government of any form can admit of.
James Madison, Federalist No. 46, January 29, 1788
The right of the people to keep and bear arms shall not be infringed. A well regulated militia, composed of the body of the people, trained to arms, is the best and most natural defense of a free country.
James Madison, I Annals of Congress 434, June 8, 1789 (delete 5/10/17)
A militia when properly formed are in fact the people themselves…and include, according to the past and general usuage of the states, all men capable of bearing arms… To preserve liberty, it is essential that the whole body of the people always possess arms, and be taught alike, especially when young, how to use them.
Richard Henry Lee, Federal Farmer No. 18, January 25, 1788
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
This may be considered as the true palladium of liberty.... The right of self defense is the first law of nature: in most governments it has been the study of rulers to confine this right within the narrowest limits possible. Wherever standing armies are kept up, and the right of the people to keep and bear arms is, under any color or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction.
St. George Tucker, Blackstone's Commentaries on the Laws of England, 1803
The supposed quietude of a good man allures the ruffian; while on the other hand, arms, like law, discourage and keep the invader and the plunderer in awe, and preserve order in the world as well as property. The balance of power is the scale of peace. The same balance would be preserved were all the world destitute of arms, for all would be alike; but since some will not, others dare not lay them aside. And while a single nation refuses to lay them down, it is proper that all should keep them up. Horrid mischief would ensue were one-half the world deprived of the use of them; for while avarice and ambition have a place in the heart of man, the weak will become a prey to the strong. The history of every age and nation establishes these truths, and facts need but little arguments when they prove themselves.
Thomas Paine, "Thoughts on Defensive War" in Pennsylvania Magazine, July 1775
What, Sir, is the use of a militia? It is to prevent the establishment of a standing army, the bane of liberty .... Whenever Governments mean to invade the rights and liberties of the people, they always attempt to destroy the militia, in order to raise an army upon their ruins.
Rep. Elbridge Gerry of Massachusetts, I Annals of Congress 750, August 17, 1789
If the representatives of the people betray their constituents, there is then no resource left but in the exertion of that original right of self-defense which is paramount to all positive forms of government, and which against the usurpations of the national rulers, may be exerted with infinitely better prospect of success than against those of the rulers of an individual state. In a single state, if the persons intrusted with supreme power become usurpers, the different parcels, subdivisions, or districts of which it consists, having no distinct government in each, can take no regular measures for defense. The citizens must rush tumultuously to arms, without concert, without system, without resource; except in their courage and despair.
Alexander Hamilton, Federalist No. 28
[I]f circumstances should at any time oblige the government to form an army of any magnitude that army can never be formidable to the liberties of the people while there is a large body of citizens, little, if at all, inferior to them in discipline and the use of arms, who stand ready to defend their own rights and those of their fellow-citizens. This appears to me the only substitute that can be devised for a standing army, and the best possible security against it, if it should exist.
Alexander Hamilton, Federalist No. 28, January 10, 1788
