"A constitution founded on these principles introduces knowledge among the people, and inspires them with a conscious dignity becoming freemen; a general emulation takes place, which causes good humor, sociability, good manners, and good morals to be general. That elevation of sentiment inspired by such a government, makes the common people brave and enterprising. That ambition which is inspired by it makes them sober, industrious, and frugal."

-- John Adams, Thoughts on Government, 1776
 
 
"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 researchers, 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."

-- John Adams, 1798

 
 
"Independence forever!"

-- John Adams' final toast to his family from his deathbed

 
 
"But what do we mean by the American Revolution? Do we mean the American war? The Revolution was effected before the war commenced. The Revolution was in the minds and hearts of the people; a change in their religious sentiments of their duties and obligations."

-- John Adams, 1818

 
 
"There is nothing which I dread so much as a division of the republic into two great parties, each arranged under its leader, and concerting measures in opposition to each other. This, in my humble apprehension, is to be dreaded as the greatest political evil under our Constitution."

-- John Adams, Letter to Jonathan Jackson (2 October 1780), "The Works of John Adams", vol 9, p.511

 
 
"There is no good government but what is republican...a republic is 'an empire of laws, and not of men'...a republic is the best of governments, so that particular arrangement of the powers of society, or in other words, that form of government which is best contrived to secure an impartial and exact execution of the law, is the best of republics."

-- John Adams, Thoughts on Government, 1776

 
 
"In politics the middle way is none at all. "

-- John Adams

 
 
"Posterity, you will never know how much it cost the present generation to preserve your freedom. I hope you will make good use of it. If you do not, I shall repent in heaven that ever I took half the pains to preserve it."

-- John Adams

 
 
"There is danger from all men. The only maxim of a free government ought to be to trust no man living with power to endanger the public liberty."

-- John Adams, Journal, 1772

 
 
"We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge or gallantry would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution is designed only for a moral and religious people. It is wholly inadequate for any other."

-- John Adams
