"No people will tamely surrender their Liberties,
nor can any be easily subdued,
when knowledge is diffused and Virtue is preserved.
On the Contrary, when People are universally ignorant,
and debauched in their Manners,
they will sink... under their own weight
without the Aid of foreign Invaders."
~Samuel Adams, letter to James Warren, 1775
"Qui tacet consentit"
