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] experience with the French philosophers only convinced him further of the need for a bicameral legislature representing the two principal social orders and, equally important, an independent executive.

[John] Adams was arguing that a separate social order existed that needed to be embodied in senates and his fellow Americans could not accept this and accused him rightly of being obsessed with the English constitution.

[ Massachusetts constitution] was [John Adams] attempt to justify that structure by the traditional notion of social estates - that the executive represented the monarchical estate, the senate the aristocratic estate, and the house of representatives the estate of the people.

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."

It was [John's Adams] Massachusetts constitution if anything that influenced people.

I think [John Adams's] influence on the federal Constitution was indirect. Many including James Madison mocked the first volume of Adams's Defence of the Constitutions of the United States in 1787. But his Massachusetts constitution was a model for those who thought about stable popular governments, with its separation of powers, its bicameral legislature, its independent judiciary, and its strong executive.
