In this highly original study of the nature of performance, Spencer Golub uses the insights of Ludwig Wittgenstein into the way language works to analyse the relationship between the linguistic and the visual in the work of a broad range of dramatists, novelists, and filmmakers, among them Richard Foreman, Mac Wellman, Peter Handke, David Mamet, and Alfred Hitchcock. Like Wittgenstein, these artists are concerned with the limits of language’s representational capacity. For Golub, it is these limits that give Wittgenstein’s thought a further, very personal significance its therapeutic quality with respect to the Obsessive Compulsive Disorder from which he suffers. Underlying what Golub calls “performance behaviour” is Wittgenstein’s notion of “pain behaviour” that which gives public expression to private experience. Golub charts new directions for exploring the relationship between theatre and philosophy, and even for scholarly criticism itself.
