"Objects of the most stupendous magnitude and measure, in which the lives and liberties of millions yet unborn are intimately interested, are now before us. We are in the very midst of a revolution the most complete, unexpected and remarkable of any in the history of nations."

-- John Adams, letter to William Cushing, 1776

"And you will, by the dignity of your conduct, afford occasion for posterity to say, when speaking of the glorious example you have exhibited to mankind, had this day been wanting, the world had never seen the last stage of perfection to which human nature is capable of attaining."

-- George Washington, The Newburgh Address, 1783

"(W)hen in the distant future some man, some faction, some interest, should set up the doctrine that none but rich men, or none but white men, or none but Anglo-Saxon white men, were entitled to life, liberty, and the pursuit of happiness, their posterity might look up again to the Declaration of Independence and take courage to renew the battle which their fathers began, so that truth and justice and mercy and all the humane and Christian virtues might not be extinguished from the land; so that no man would hereafter dare to limit and circumscribe the great principles on which the temple of liberty was being built."

-- Abraham Lincoln, August 17, 1858

_"Without wishing to damp the ardor of curiosity or influence the freedom of inquiry, I will hazard a prediction that, after the most industrious and impartial researches, the longest liver of you all will find no principles, institutions or systems of education more fit in general to be transmitted to your posterity than those you have received from your ancestors...
The general Principles, on which the Fathers Atchieved Independence, were the only Principles in which that beautiful Assembly of young Gentlemen could Unite, and these Principles only could be intended by them in their Address, or by me in my Answer. And what were these general Principles? I answer, the general Principles of Christianity, in which all those Sects were united: And the general Principles of English and American Liberty, in which all those young Men United, and which had United all Parties in America, in Majorities sufficient to assert and maintain her Independence. Now I will avow, that I then believed, and now believe, that those general Principles of Christianity, are as eternal and immutable, as the Existence and Attributes of God; and that those Principles of Liberty, are as unalterable as human Nature and our terrestrial, mundane System. I could therefore safely say, consistently with all my then and present Information, that I believed they would never make Discoveries in contradiction to these general Principles."


-- John Adams, letter to the young men of the Philadelphia, 1798
