Jacques Derrida took up with vigor the Socratic vocation of philosophy as a kind of dying. Notoriously linked to discourses on "the death of the author" (and almost universally misunderstood on this score), Derrida's work was regularly haunted by ghosts. Death inscribed itself in his corpus and has now left its mark on his body, and we are left to mourn.

It is not without reason that some of his most powerful meditations—on Levinas, de Man, Deleuze, Lyotard and others—come to us in the form of eulogies and memorials.

It has been the mistake of his critics—both in the academy and media—to conclude from Derrida's preoccupation with death that deconstruction is simply the next nihilism. And so Derrida has been vilified as the enemy of truth, justice, the university, and many more of our cherished institutions and values. The myths and lies—yes, lies—about Derrida persist even in his death (Jonathan Kandell's obituary in The New York Times was a travesty).

The news of Derrida's death came as a surprise, though we've known of his illness for over a year now. Most surprising is how sad it has made me. I received ...
