Among the most influential philosophers of science of the past half-century, Helen Longino has reshaped our understanding of how scientific knowledge is produced, evaluated, and shaped by social values. Her work across feminist philosophy, philosophy of science, philosophy of biology, and social epistemology has transformed debates about objectivity, evidence, and the relationship between science and society. This original collection, which includes an oral history and comprehensive bibliography, explores the breadth and continuing significance of Longino's ideas. Contributors examine how her framework illuminates questions in fields ranging from education and psychology to immunology, hormone research, agricultural science, economics, public policy, and activism. Written by leading scholars and a new generation of philosophers engaging with her work, the volume provides both an introduction to Longino's thought and a critical exploration of the many ways her ideas continue to shape discussions about science, values, and social inquiry.
