"No people will tamely surrender their Liberties, nor can any be easily subdued, when knowledge is diffusd and Virtue is preservd. On the Contrary, when People are universally ignorant, and debauchd in their Manners, they will sink under their own weight without the Aid of foreign Invaders." 

-- Samuel Adams (letter to James Warren, 4 November 1775)
