If history teaches anything, it teaches humility.

[John Adams and Tomas Jefferson] shared experience in 1775 - 1776 in bringing about the separation from Britain and their service in Europe cemented a friendship that in the end withstood the most serious political and religious differences that one could imagine, especially their differences over the French Revolution. It was probably Jefferson's obsession with politeness and civility that kept the relationship from becoming irreparably broken.

[Benjamin] Franklin may be a great philosopher, [John Adams] told his diary in 1779, but "as a Legislator in America he has done very little."

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

[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.

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.
