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.

[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.

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.

[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.

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."

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.

[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."
