The essays in this collection--several of which are published here for the first time--explore the genesis and historical development of this optimistic configuration in ethical thought and the ways in which it has shown itself to be unfounded and misguided. Discussions of Greco-Roman antiquity and of the philosophies of Socrates, Plato, Hegel, Marx, Nietzsche, and Adorno play a central role in many of these essays. Geuss also ranges over such topics as the concepts of intelligibility, authority, democracy, and criticism; the role of lying in politics; architecture; the place of theology in ethics; tragedy and comedy; and the struggle between realism and our search for meaning. Characterized by Geuss's wide-ranging interests in literature, philosophy, and history, and by his political commitment and trenchant style, A World without Why raises fundamental questions about the viability not just of specific ethical concepts and theses, but of our most basic assumptions about what ethics could and must be.
