What is it about irony--as an object of serious philosophical reflection and a literary technique of considerable elasticity--that makes it an occasion for endless critical debate? This book responds to this question by focusing on several key moments in German Romanticism and its afterlife in twentieth-century French thought and writing. It includes chapters on Friedrich Schlegel, Soren Kierkegaard, Friedrich Nietzsche, Thomas Mann, Jean Paulhan, Jacques Derrida, and Paul de Man.
