[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 letters to [his wife] Abigail are wonderful. In his letters, he is loving, humorous, preachy, learned, and saucy. He speaks to her with almost complete abandon, revealing all of his sensuous and vulnerable nature.

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."

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.

[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."

[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.
