[John Adams] always felt that his contribution to bringing about independence went unappreciated, especially after the 1790s when [Tomas] Jefferson began to be lauded as the "author" of the Declaration of Independence.

This rationale, which justified the mixed constitution of Great Britain, might have made some sense in 1776, but by 1787 most American thinkers had come to believe that all parts of their balanced governments represented in one way or another the sovereign people. They had left the Aristotelian idea of mixed estates - monarchy, aristocracy, and democracy - way behind. [John] Adams had not, and his stubbornness on this point caused him no end of trouble.

The Massachusetts constitution was written much later than the other revolutionary state constitutions, and thus it avoids some of the earlier mistakes. The executive is stronger, with a limited veto; the senate is more formidable; and the judiciary is independent.

[John Adams's] vividly descriptive prose is supremely quotable. Adams wears his heart on his sleeve and reveals all of his ambitions, doubts, and insecurities, especially in his diary, which is one of the greatest and most readable in all of American literature.

More than any other figure in our history [Tomas] Jefferson is responsible for the idea of American exceptionalism.

I think [John] Adams was correct when he said that his May resolutions were "an Epocha, a decisive Event," and tantamount to a declaration of independence.

[John] Adams's letters reveal his persistence and determination to win over the Dutch against all odds and to convince them and the other peoples of Europe of the potential greatness of the United States and of the importance of the Revolution to the world.
