'There is nothing outside the text.' Possibly no single statement has caused such a storm in critical theory as this famous observation by the French philosopher, Jacques Derrida. While it is often misunderstood as meaning that nothing is real and that political actions are therefore pointless, Debating Derrida demonstrates that Derrida's philosophy does not lack political conviction.

Niall Lucy examines three key terms - text, writing and differance - as they are used in three famous debates: Derrida's disputes over speech-acts with John R. Searle, over discourse with Michel Foucault and over apartheid. Lucy also takes up the issue of Derrida's relationship to postmodernism and questions the 'political imperative' of the need to justify philosophy and the humanities in general according to a notion of their 'usefulness'.

Debating Derrida decisively shows that instead of disagreeing with Derrida, we should rather be defending him.
