Realism and real politics. The gap between promise and practice in Bernard Williams' realism

This paper seeks to show that Bernard Williams' approach to legitimacy falls short of its aspirations in ways that cast doubt on its fitness for guiding the practice of future realist political theory. More precisely, the paper focuses on the shortcomings of Williams' realism in establishing a connection to (the practices of) politics, and on how to redeem those shortcomings in a way that would render them suitable for guiding future realist political theory. The first substantive section of the paper considers how compatible Williams' commitments to diagnosis and interpretation are, with how he spells out his realist thought. The second section argues that making good on Williams' commitments requires realist political theorists to rethink the sources of their insights and the basis of their claims, and sketches pragmatist and ethnographic approaches as promising examples of how realists could match theoretical commitments in practice.
