[John Adams] is impressed with [Tomas] Jefferson's learning, but noted his silence during the debates in the Congress: "I never heard him utter three Sentences together."

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.

[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.

[John] Adams was the best and most colorful stylist among the Founders. Although [Tomas] Jefferson is widely regarded as the smoothest writer, Adams is by far the most engaging and imaginative.

[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.

[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."

A mutual friend, Benjamin Rush, brought [Tomas Jefferson and John Adams] together in 1812, and they went on to exchange letters for the rest of their lives. But in their correspondence they tended to avoid the most controversial issues, such as slavery.
