This book examines the overlooked yet pivotal concept of ignorance in environmental philosophy, critiquing its marginalization in both science and philosophy. It identifies ignorance as the “unknown unknowns” that science struggles to address and argues that academic reliance on identity hinders understanding of such complexities. Drawing on Derrida’s critique of identity, the book demonstrates how ignorance challenges the authority of scientific and philosophical frameworks, questioning whether these disciplines can genuinely contribute to solving environmental crises.
