Therefore “Wise and able Politicians will guard against other Vices,” and be attentive to promote every Virtue. He who is void of virtuous Attachments in private Life, is, or very soon will be void of all Regard for his Country. There is seldom an Instance of a Man guilty of betraying his Country, who had not before lost the Feeling of moral Obligations in his private Connections… Since private and publick Vices, are in Reality, though not always apparently, so nearly connected, of how much Importance, how necessary is it, that the utmost Pains be taken by the Publick, to have the Principles of Virtue early inculcated on the Minds even of Children, and the moral Sense kept alive, and that the wise Institutions of our Ancestors for these great Purposes be encouragd by the Government. For 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 Nov. 1775
