For many decades, race and racism have been common areas of study in departments of sociology, history, political science, English, and anthropology. Much more recently, as the historical concept of race and racial categories have faced significant scientific and political challenges, philosophers have become more interested in these areas. This changing understanding of the ontology of race has invited inquiry from researchers in moral philosophy, metaphysics, epistemology, philosophy of science, philosophy of language, and aesthetics. The Routledge Companion to Philosophy of Race offers in one comprehensive volume newly written articles on race from the world’s leading analytic and continental philosophers. It is, however, accessible to a readership beyond philosophy as well, providing a cohesive reference for a wide student and academic readership. The Companion synthesizes current philosophical understandings of race, providing37 chapters on the history of philosophy and race as well as how race might be investigated in the usual frameworks of contemporary philosophy. The volume concludes with a section on philosophical approaches to some topics with broad interest outside of philosophy, like colonialism, affirmative action, eugenics, immigration, race and disability, and post-racialism. By clearly explaining and carefully organizing the leading current philosophical thinking on race, this timely collection will help define the subject and bring renewed understanding of race to students and researchers in the humanities, social science, and sciences.
