As its title suggests, The Truth About Postmodernism disputes a good deal of what currently passes for advance theoretical wisdom. Above all it mounts a challenge to those fashionable doctrines - variants of the 'end-of-ideology' theme - that assimilate truth to some existing range of language-games, discourses, or in-place consensus beliefs. Norris's book will be welcomed for its clarity of style, its depth of philosophical engagement, and its refusal to endorse the more facile varieties of present-day textualist thought. It will also serve as a timely reminder that the 'politics of theory' cannot be practised in safe isolation from the politics (and ethics) of activist social concern.
