Creating senates, the French critics said, implied that there was another social order besides the people represented in the houses of representatives. [John] Adams actually agreed with that implication and argued that the aristocracy and the people had to have separate houses; this was the only way the power of the aristocracy could be contained.

History is the queen of the humanities. It teaches wisdom and humility, and it tells us how things change through time.

[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."

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

I think [John Adams's] influence on the federal Constitution was indirect. Many including James Madison mocked the first volume of Adams's Defence of the Constitutions of the United States in 1787. But his Massachusetts constitution was a model for those who thought about stable popular governments, with its separation of powers, its bicameral legislature, its independent judiciary, and its strong executive.

[ Massachusetts constitution] was [John Adams] attempt to justify that structure by the traditional notion of social estates - that the executive represented the monarchical estate, the senate the aristocratic estate, and the house of representatives the estate of the people.

By 1782 [John Adams] had come to feel for [Benjamin] Franklin "no other sentiments than Contempt or Abhorrence."
