In this undergraduate textbook Lewis R. Gordon offers the first comprehensive treatment of Africana philosophy, beginning with the emergence of an Africana (i.e. African diasporic) consciousness in the Afro-Arabic world of the Middle Ages. He argues that much of modern thought emerged out of early conflicts between Islam and Christianity that culminated in the expulsion of the Moors from the Iberian Peninsula, and from the subsequent expansion of racism, enslavement, and colonialism which in their turn stimulated reflections on reason, liberation, and the meaning of being human. His book takes the student reader on a journey from Africa through Europe, North and South America, the Caribbean, and back to Africa, as he explores the challenges posed to our understanding of knowledge and freedom today, and the response to them which can be found within Africana philosophy.
