'This is an impressive, comprehensive treatment of what international relations theorists have learned throughout the 'hot peace' decade that followed the cold war. Self-described realists remind us of the importance of remembering Marx, the social scientist, in this era of triumphal capitalism. Putative Marxists restate the relevance of Kant, the historian and ethicist, in a world in which depoliticizing postmodernists question the substance of triumphal liberalism. And scholars across paradigms emphasize the centrality of classical theorizing to the conflict and inequality of the current world.' Craig N. Murphy, M.
