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.

Perhaps more significant than his experience in Europe, though, was [John] Adams's experience in his own country, and his extensive reading on the history of the English constitution. In 1779, he had an opportunity to try out his ideas by framing the Massachusetts constitution.

I think [John's Adams] descriptions of the personalities of [Benjamin] Franklin and [Tomas] Jefferson and others were pretty accurate. It is only when he felt he was wronged by them that he lets loose his anger and resentment.

Americans, [John Adams] wrote in 1780, believed that their "revolution is as much for the benefit of the generality of Mankind in Europe, as for their own."

[Tomas] Jefferson believed that the United States was a chosen nation with a special responsibility to spread democracy around the world.

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.

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