This book offers a stimulating new approach to studying social and political theory. It combines specially selected extracts from the political classics with original and insightful essays offering a commentary upon them. The reader is drawn into a dialogue with the Western political tradition's principal thinkers, whose ideas provide a common currency in which to debate the problems facing modern societies. Each of the twelve chapters combines extracts from two (or in one case three) political philosophers on a key political concept with a commentary essay. Each chapter does more than just introduce the reader to the classics; it also explains, via the commentary essay, the key concepts of political debate, and the historical contexts which led the thinkers to their different understandings of the nature of society. -- .
