[W]hat country can preserve its liberties, if its rulers are not
warned from time to time that [the] people preserve the spirit of
resistance? Let them take arms...The tree of liberty must be
refreshed from time to time, with the blood of patriots and tyrants.
-- Thomas Jefferson, letter to Col. William S. Smith, 1787
Ay, down to the dust with them, slaves as they are!
From this hour let the blood in their dastardly veins,
That shrunk at the first touch of Liberty's war,
Be wasted for tyrants, or stagnate in chains....
