This edited collection charts the development of, and prospects for, conceiving knowledge as a social phenomenon. The origin, aims and growth of the journal Social Epistemology, founded in 1987, serves to anchor each of the book’s contributions. Each contribution offers a unique, but related, insight on current issues affecting the organization and production of knowledge. In addition, each contribution proposes necessary questions, practices and frameworks relevant to the rapidly changing landscape of our conceptions of knowledge. The book examines the commercialization of science, the neoliberal university, the status and conduct of philosophy, the cultures of computer software and social networking, the practical, political and anthropological applications of social epistemology, and how we come to define what human beings are and what activities human beings can, and should, sustain. A diverse group of noted, international scholars lends necessary, original and challenging perspectives on our collective approach to knowledge.This book was originally published as a special issue of Social Epistemology.
