[John] Adams's letters to [his wife] Abigail are wonderful. In his letters, he is loving, humorous, preachy, learned, and saucy. He speaks to her with almost complete abandon, revealing all of his sensuous and vulnerable nature.

[John's Adams] description of [Benjamin] Franklin in a letter to [his wife] Abigail in 1775 is laudatory. Only when he experiences all the adulation paid to Franklin in Paris does he begin to change his tune.

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.

By the time [John Adams] came to write his Defence of the Constitutions of the United States in 1787 he had as dark a view of the American character as that of any critic in our history.

[John Adams] letters courting Abigail Smith are especially priceless. In one of 1764 he addresses her as "Miss Adorable" and says that "By the same Token that the Bearer hereof satt up with you last night I hereby order you to give him, as many Kisses, and as many Hours of your Company after 9 O'Clock as he shall please to Demand and charge them to my Account."

[John] Adams never hid his jealousy and resentment of the other Founders, especially Benjamin Franklin.

[The Massachusetts constitution] resembles the federal Constitution of 1787 more closely than any of the other revolutionary state constitutions. It was also drawn up by a special convention, and it provided for popular ratification - practices that were followed by the drafters of the federal Constitution of 1787 and subsequent state constitution-makers.
