Wittgenstein and the Idea of a Critical Social Theory [PDF ebook] 
A Critique of Giddens, Habermas and Bhaskar

This book uses the philosophy of Wittgenstein as a perspective from which to challenge the very idea of critical social theory, represented preeminently by Giddens, Habermas and Bhaskar. Renouncing the quest for an alternative Wittgensteinian theory of social and political life, the author shows that Wittgenstein nevertheless has considerable significance for critical thought and practice.
