Vázquez believes that, both between the field anthropologists as well as theoretical ones, there is consensus in the recognition of a crisis which affects the theoretical paradigms in socio-cultural anthropology. To face this situation he proposes a theoretical approach which allows more complete and fecund interpretations: the historical-critical approach (current epistemological need). In this paper the author also ratifies the need for social scientists in countries of the periphery to promote and stimulate the production of scientific theory among themselves, for it is sometimes underestimated by field anthropologists.
