If history teaches anything, it teaches humility.
The relationship between [John] Adams and [Tomas] Jefferson was extraordinary. They differed on every conceivable issue, except on the Revolution and the love of their country.
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.
[Tomas] Jefferson believed that the United States was a chosen nation with a special responsibility to spread democracy around the world.
History is the queen of the humanities. It teaches wisdom and humility, and it tells us how things change through time.
As early as 1776, [John Adams] expressed his doubts about America's capacity for virtue. "I have seen all along my Life, Such Selfishness, and Littleness even in New England, that I sometimes tremble to think that, altho We are engaged in the best Cause that ever employed the Human Heart, yet the Prospect of success is doubtfull not for Want of Power or of Wisdom, but of Virtue."
[John] Adams identified himself with the political theories of [James] Harrington, [John] Locke, and [Charles-Louis] Montesquieu, whose ideas of constitutionalism, he believed, were applicable to all peoples everywhere; they were his contribution to what he called "the divine science of politics."
[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."
The Declaration [of Independence] was a committee report, and [Tomas] Jefferson was simply the draftsman. [John] Adams's crucial role in bringing about independence in the Continental Congress has tended to get forgotten.
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."
[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.
[John] Adams was arguing that a separate social order existed that needed to be embodied in senates and his fellow Americans could not accept this and accused him rightly of being obsessed with the English constitution.
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.
More than any other figure in our history [Tomas] Jefferson is responsible for the idea of American exceptionalism.
The Massachusetts constitution was written much later than the other revolutionary state constitutions, and thus it avoids some of the earlier mistakes. The executive is stronger, with a limited veto; the senate is more formidable; and the judiciary is independent.
It was [John's Adams] Massachusetts constitution if anything that influenced people.
[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.
[John] Adams never had an optimistic view of human nature, and his experience in the Congress and abroad only deepened his suspicion that his fellow Americans might not have the character to sustain a republican government.
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' writings] had indicted the United States for slavishly copying the English constitution by erecting bicameral legislatures in their state constitutions, most drafted in 1776.
By 1782 [John Adams] had come to feel for [Benjamin] Franklin "no other sentiments than Contempt or Abhorrence."
[John Adams's] vividly descriptive prose is supremely quotable. Adams wears his heart on his sleeve and reveals all of his ambitions, doubts, and insecurities, especially in his diary, which is one of the greatest and most readable in all of American literature.
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 never hid his jealousy and resentment of the other Founders, especially Benjamin Franklin.
[John Adams] diary, of course, is even more revealing of his feelings. Both his letters to [his wife] Abigail and his diary tell us what he really thinks about people and events.
