Of the many questions provoked by Blanchot's thought and writing, that of understanding its ethical and political significance is perhaps the most pressing. Spanning his literary critical and philosophical writings, and addressing such major concepts as the image and the neuter, Blanchot's Vigilance presents a sustained analysis of Blanchot's response to Levinas's ethical thought, the political commitments of the Surrealists, Heidegger's readings of the ancient Greeks, and the claims of psychoanalysis. In a series of thorough and lucid readings, Iyer presents Blanchot's central concern as maintaining a kind of vigilance over a difference which opens in the articulation of sense.
