Go back even earlier than Locke, and read Hobbes..(leviathan, et al)..Madison was certainly the cerebral member of the bunch, but Adams (John) was also well read and understood well the lessons of history.....he has taken a rough rap from history, however, primarily due to his early loyalty to King George.
I do tend to agree with much the antt-federalists argued about, although it is clear that the Federalist group never considered the possibility, and eventuality, of life-long politicians, such as we have today..it was dismissed as folly...after all, what kind of person would want to make a career of that?? As such, the Federalists were proven to be right on most of their concerns.
As Franklin so eloquently said, when asked what they had accomplished in the continental congress...”a republic, if you can keep it”
Thanks for your reply. I have gone back further. Some of the ideas from the left go as far back as Ancient Greece. One of my passions is studying history. The other passion is studying and understanding Constitutional Law. :)
