Here are a few I have, there are no doubt many more members that can add to this list.
They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.
---Benjamin Franklin, Historical Review of Pennsylvania, 1759
Guard with jealous attention the public liberty. Suspect every one who approaches that jewel. Unfortunately, nothing will preserve it but downright force. Whenever you give up that force, you are ruined.
---Patrick Henry 1788 (after the revolution)
When the resolution of enslaving America was formed in Great Britain, the British Parliament was advised by an artful man, who was governor of Pennsylvania, to disarm the people; that it was the best and most effectual way to enslave them; but that they should not do it openly, but weaken them, and let them sink gradually...I ask, who are the militia?

"We must all hang together, or most assuredly we will all hang separately."

A well regulated militia, composed of the body of the people, trained in arms, is the best most natural defense of a free country. -James Madison
Do not separate text from historical background. If you do, you will have perverted and subverted the Constitution, which can only end in a distorted, bastardized form of illegitimate government. -James Madison

"If cowardly and dishonorable men sometimes shoot unarmed men with army pistols or guns, the evil must be prevented by the penitentiary and gallows, and not by a deprivation of a constitutional privilege." - Abraham Lincoln
"Laws that forbid the carrying of arms ... 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
