What was Of Grammatology about? When Madeleine, the heroine of Jeffrey Eugenides's campus novel The Marriage Plot, asks a young theory-head this question, she is immediately set straight: 'If it was "about" anything, then it was about the need to stop thinking of books as being about things.' That's not so far off. In all three books, Derrida's argument was that Western thought from Plato to Rousseau to Lévi-Strauss had been hopelessly entangled in the illusion that language might provide us with access to a reality beyond language, beyond metaphor: an unmediated experience of truth and being which he called 'presence'.—Not in the Mood by Adam Shatz is an essay in The London Review of Books about a new biography of the French philosopher Jacques Derrida. The review does a good job of explaining Derrida's theories in simple language and putting it in the context of his life, from his childhood as French Jew in Vichy-controlled Algeria to his later years as a globetrotting academic star. For a complimentary perspective on Derrida, you can do worse than starting with these thoughts on his relevance for historians and progressives.
