Exploring the risks, ambiguities, and unstable conceptual worlds of contemporary thought, Crossover Queries brings together the wide-ranging writings, across twenty years, of one of our most important philosophers. Ranging from twentieth-century European philosophy—the thought of Heidegger, Foucault, Derrida, Levinas, Janicaud, and others—to novels and artworks, music and dance, from traditional Jewish thought to Jain and Buddhist metaphysics, Wyschogrod’s work opens radically new vistas while remaining mindful that the philosopher stands within and is responsible to a philosophical legacy conditioned by the negative. Rather than point to a Hegelian dialectic of overcoming negation or to a postmetaphysical exhaustion, Wyschogrod treats negative moments as opening novel spaces for thought. She probes both the desire for God and an ethics grounded in the interests of the other person, seeing these as moments both of crossing over and of negation. Alert to the catastrophes that have marked our times, she exposes the underlying logical structures of nihilatory forces that have been exerted to exterminate whole peoples. Analyzing the negations of biological research and cultural images of mechanized and robotic bodies, she shows how they contest the body as lived in ordinary experience. “Crossover Queries brings together important essays on a remarkable range of topics by one of our most insightful cultural critics. Commenting on philosophical and theological issues that have shaped the recent past as well as scientific and technological questions that will preoccupy us in the near future, Wyschogrod consistently alerts us to the urgency of problems whose importance few recognize. To avoid the challenge these essays pose is to avoid responsibility for a future that appears to be increasingly fragile.”—Mark C. Taylor, Columbia University
