ABSTRACT
I must confess that I felt a degree of ambivalence when I was invited to take part in the discussion of Derrida’s legacies at the Tate Modern in which this book originated. This ambivalence originates in my attitude to Derrida’s philosophical interventions since the appearance of Grammatology and Writing and Difference in the late 1960s. For what it’s worth, some of the philosophical themes with which Derrida was identified seem to me beyond dispute.1
