1 The notion of a ‘theory explosion’ has been taken up and discussed by a number of scholars in theatre and performance studies, such as Janelle Reinelt, Joseph Roach and Jon McKenzie, and indeed across the arts and humanities more broadly. In general, this refers to the translation, dissemination and subsequent influence of key structuralist and then post-structuralist texts (including those by Jacques Derrida, Jacques Lacan and Michel Foucault) on the study of the arts and humanities in anglophone universities, starting in the 1970s and 1980s. In their ‘General Introduction’ to the first edition of Critical Theory and Performance, editors Reinelt and Roach provide a very helpful account of the specific impact of the ‘theory explosion’ on theatre and performance studies: ‘There has been a theory explosion, and it has had important consequences for both theater studies and other humanities as well. First, it has enlarged the conception of performance in ways not envisaged in the traditional study of drama and therefore reduced some of the separation of specialities between theater history, theory/criticism, and theater practice . . . Second, the “new” theory has returned the humanities to philosophy . . . In fact, much of the “new theory” derives from the work of philosophers . . . Derrida's critique of metaphysics, Paul Ricoeur's phenomenology, J.L. Austin's speech/act theory, and Jean-François Lyotard's conception of the postmodern’.
