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."

[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's letters reveal his persistence and determination to win over the Dutch against all odds and to convince them and the other peoples of Europe of the potential greatness of the United States and of the importance of the Revolution to the world.

[John] Adams's perception of Europe, and especially France, was clearly different than [Tomas] Jefferson's. For Jefferson, the luxury and sophistication of Europe only made American simplicity and virtue appear dearer. For Adams, by contrast, Europe represented what America was fast becoming - a society consumed by luxury and vice and fundamentally riven by a struggle between rich and poor, gentlemen and commoners.

After [Tomas] Jefferson's defeat of [John] Adams in the presidential election of 1800, they didn't communicate with one another for more than a decade.

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.

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.
