Query: An Excellent Review

If the other reviewers are having trouble determining the value of the "Four Pillars" or perhaps Dr. Cox's thesis in general, perhaps they would have received more value out of spending a semester or two in Dr. Cox's classes on "Politics and Rhetoric" and "American Political Thought" while he taught at the University of Buffalo. In those courses he used the excellent book "The Constitution of 1787" to demonstrate the importance of the four most important documents in American political and social life. I found this book to be cogent and a refresher course from my years as a political science student at the University of Buffalo.
