His entry for the Stanford Encycl of Phil is here.
“Africana philosophy” is the name for an emergent and still developing field of ideas and idea-spaces, intellectual endeavors, discourses, and discursive networks within and beyond academic philosophy that was recognized as such by national and international organizations of professional philosophers, including the American Philosophical Association, starting in the 1980s. Thus, the name does not refer to a particular philosophy, philosophical system, method, or tradition. Rather, Africana philosophy is a third-order, metaphilosophical, umbrella-concept used to bring organizing oversight to various efforts of philosophizing—that is, activities of reflective, critical thinking and articulation and aesthetic expression—engaged in by persons and peoples African and of African descent who were and are indigenous residents of continental Africa and residents of the many African Diasporas worldwide. In all cases the point of much of the philosophizings has been to confer meaningful orderings on individual and shared living and on natural and social worlds while resolving recurrent, emergent, and radically disruptive challenges to existence so as to survive, endure, and flourish across successive generations.
