This chapter illuminates the critical theoretical potential in anthropology, showing both ways in which it has been fruitfully actualised, and, most importantly, how it forms one of the rare inexhaustible undercurrents of anthropological thinking itself, as a capacity for creating new concepts. In their landmark volume, Anthropology as Cultural Critique, George Marcus and Michael Fischer acknowledged the Frankfurt School as, 'perhaps the most important stimulus to the revitalised sense of cultural criticism among the younger generation of American anthropologists during the 1960s and 1970s'. The chapter discusses the Taussig's Hauka example, as it is the one that has brought his approach of the mimetic faculty in the broadest dialogue with other anthropologists and their work. It examines the Hauka movement amongst the Songhay in the late 1920s, Taussig focused on spirit possession practices.
