The 'moment' of May 1968 offered a vivid example of intellectual engagement with radical politics, which dominated the late 1960s and 1970s but arguably became pasš thereafter with the emergence of a depoliticised post-modernism and the seeming demise of Marxism after the fall of Soviet Communism. However, more recently, there has been a revival of interest in political engagement, with actions such as the demonstrations against the Iraq War and the Occupy movement. Pawling focuses on a number of key writers who have made significant contributions to critical theory in what can be called the 'spirit of '68', including Sartre, Derrida, Badiou, Jameson and Said. These figures do not necessarily share the same perspective on questions such as the role of the 'subject' and the political relevance of art in cultural struggle; however, Pawling concludes that they do share a key problematic: namely, how to understand the dialectical relationship between the formal imperatives of critical theory and its political conditions of existence.
