“If ye love wealth (ie: 401k’s, houses, bank accounts, job security) better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” – Samuel Adams, 1776 (updates for 2022 in parantheses)

“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

“Whenever the legislators endeavor to take away and destroy the property of the people, or to reduce them to slavery under arbitrary power, they put themselves into a state of war with the people, who are thereupon absolved from any further obedience.” ~ John Locke (1690)

“The right of the citizens to keep and bear arms has justly been considered, as the palladium of the liberties of a republic; since it offers a strong moral check against the usurpation and arbitrary power of rulers; and will generally, even if these [usurpers] are successful in the first instance, enable the people to resist and triumph over them.” – Joseph Story, Commentaries on the Constitution of the United States, 1833

“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… The citizens must rush tumultuously to arms, without concert, without system, without resource; except in their courage and despair.” 
Alexander Hamilton, Federalist No. 28

“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 John Cartwright, 5 June 1824

“Before a standing army can rule, the people must be disarmed, as they are in almost every country in Europe. The supreme power in America cannot enforce unjust laws by the sword; because the whole body of the people are armed, and constitute a force superior to any band of regular troops.” – Noah Webster, An Examination of the Leading Principles of the Federal Constitution, October 10, 1787

“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 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

“What country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance. Let them take arms.” – Thomas Jefferson, remark to James Madison, 1787
