[John] Adams was the best and most colorful stylist among the Founders. Although [Tomas] Jefferson is widely regarded as the smoothest writer, Adams is by far the most engaging and imaginative.

Deeply versed in history, [John Adams] said over and over that America had no special providence, no special role in history, that Americans were no different from other peoples, that the United States was just as susceptible to viciousness and corruption as any other nation. In this regard, at least, Jefferson's vision has clearly won the day.

[John] Adams said his objective in writing his Defence of the Constitutions of the United States and his Davila essays was to counter what he thought was the unfair criticism of the American state constitutions made by the French philosophers, especially [Anne Robert Jacques] Turgot.

[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.

I think [John Adams] developed a much deeper suspicion of France and the other European powers than he had earlier. He lost much if not all of the utopian thinking about international politics and diplomacy expressed in his Model Treaty of 1776 and became much more cynical about the world.

[John Adams] is impressed with [Tomas] Jefferson's learning, but noted his silence during the debates in the Congress: "I never heard him utter three Sentences together."

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