"Nothing...is unchangeable but the inherent and unalienable rights of man."
-- Thomas Jefferson (letter to John Cartwright, 1824)
Reference: The Writings of Thomas Jefferson, Lipscomb and Bergh,
eds., 16:48.
"If ye love wealth 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 your arms.
Crouch down and lick the hands which feed you.
May your chains set lightly upon you,
and may posterity forget that you were our countrymen."
-- Samuel Adams
(1722-1803), was known as the "Father of the American Revolution."
1776
