Featuring an international team of specialists on the subject, The Edinburgh Companion to Critical Theory provides a comprehensive analysis of the changing role of critical theory in the new century. Taking note of the many new theoretical and socio-political developments in recent years, the volume conclusively demonstrates critical theory's continuing relevance across disciplines ranging from the arts and social sciences through to the hard sciences. Being theoretically informed is not an optional part of study any more, it is a necessary, central part, and The Companion will bring readers up to date with what is happening across the spectrum of critical theory. The volume consists of 11 sections comprising 28 chapters, each covering a particular branch of critical theory from Marxism through to present-day developments such as Cognitive Theory. Every chapter considers the historical development of the theory in question, explaining the main concepts and thinkers involved, before proceeding to assess where it stands in relation to current academic and socio-political concerns and debates. Outlining recent advances in each area, and the emergence of new voices, The Companion offers readers a welcome opportunity to reorient themselves within the history and role of critical theory in its many forms.
