This revised edition, originally published in 1955 by Holt, Rinehart, and Winston, provides a comprehensive record of the most significant political ideas in this country from Massachusetts puritanism to post-World War II conservatism. Its emphasis is on the political concepts which have been articulated in the different political eras in our history. The book relates to three primary value systems: religious pluralism, capitalistic economics, and political-social democracy. It is the effort of statesmen and theorists to achieve compatibility of these differing points of view.
