This original reading of Kant's third critique, "The Critique of Judgement-Power", provides an innovative view of the role of judgement in current theoretical debates, in both the humanities and social sciences. Judgement serves as a focus for interdisciplinary aspirations - spanning theoretical, practical and aesthetic as a site for the exploration of questions of rationality and difference which characterize the "postmodern" condition. This has recognized that judgement is inevitably aporetic and that law and difference are inextricably entwined. This book clarifies some of the issues in the debate through a historical analysis of the third "Critique" which employs both deconstructionist and materialist strategies of interpretation.
