Based on Nietzsche’s suppositions, Faucoult provides two explanations to the discussion on the meaning of identity when attributed a genealogical character : emergency or the point of arising as a possibility for reflections on origin (Entstehung in German), or the body as a surface of events’ inscriptions (Herkunft in German). The latter account underlies the discussion on the batuque, an Afro-Brazilan dance and music, as an identity constructing practice of Afrodescendent Brazilian populations.
