For a long time, the term “ideology” was in disrepute, having become associated with such unfashionable notions as fundamental truth and the eternal verities. The tide has turned, and recent years have seen a revival of interest in the questions that ideology poses to social and cultural theory and to political practice. Including Slavoj Žižek’s study of the development of the concept from Marx to the present, assessments of the contributions of Lukács and the Frankfurt School by Terry Eagleton, Peter Dews and Seyla Benhabib, and essays by Adorno, Lacan and Althusser, `Mapping Ideology’ is an invaluable guide to the most dynamic field in cultural theory.
