This program provides a general, comparative introduction to the major concepts and themes of political science. The title of the book, Power & Choice, indicates a subsidiary theme that recurs at intervals. We may view politics as (1) the use of power or (2) the production of a public choice. Often one or the other is heavily emphasized in approaching the subject. Marxism emphasizes politics as the use of power, while pluralism and much formal modeling work emphasize the emergence of public choices.
