There is no more central concept in contemporary Marxian theory than that of exploitation. Western analytical Marxists have refined and revised the concept. Third World theorists have extended it from class to country. Political regimes have drawn policy conclusions. Dr. Otubusin has constructed a framework within which to situate these developments, one which highlights the normative presuppositions of the various theorists. He has managed a synthesis of a vast amount of quite diverse literature and has offered a cogent critical analysis. Dr. Otubusin has exploited his training in both philosophy and political science to produce a compelling piece of work.
