Jacques Derrida, Jean-Francois Lyotard, Jean Baudrillard and Geoffrey Hartman all claim to have found a way to transcend value judgment. This book confronts these assertions and argues that tinkers such as these have, by their rejection of conventional methods of constructing value judgments, succeeded in problematizing the entire area of aesthetics. Stuart Sim treats posttructuralism and postmodernism as forms of anti-aesthetics and contextualises the movements within a longer-running tradition of anti-foundationalism and radical skepticism in Western philosophy. Arguing from a broadly socialist, historical materialist position he demands that discourses be made to declare their ideological commitments. While the radical skepticism of Derrida, Lyotard, Baudrillard, and their followers is shown to be ultimately philosophically unsustainable and ideologically suspect form a left-wing point of view, Sim concludes that these critics nevertheless point to a need for reassessment of methods and objectives among critical theorists on the left.
