[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."

Again and again [Tomas] Jefferson deftly sidesteps many of [John] Adams's often provocative remarks. They both felt the correspondence, which was written for posterity, was too important to risk by being too candid with one another.

[John] Adams never hid his jealousy and resentment of the other Founders, especially Benjamin Franklin.

[John's Adams] description of [Benjamin] Franklin in a letter to [his wife] Abigail in 1775 is laudatory. Only when he experiences all the adulation paid to Franklin in Paris does he begin to change his tune.

[John Adams] always felt that his contribution to bringing about independence went unappreciated, especially after the 1790s when [Tomas] Jefferson began to be lauded as the "author" of the Declaration of Independence.

[John Adams] letters courting Abigail Smith are especially priceless. In one of 1764 he addresses her as "Miss Adorable" and says that "By the same Token that the Bearer hereof satt up with you last night I hereby order you to give him, as many Kisses, and as many Hours of your Company after 9 O'Clock as he shall please to Demand and charge them to my Account."

[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.
