In his works written before 1970s, Michel Foucault makes use of archeology, while he, being inspired by Nietzsche, joins genealogy in his works written after 1970; accordingly, one is entitled to speak of two distinct important period in his career: archeological and genealogical.
The authors, outlining both Nietzsche’s genealogy and Foucault’s archeology, explain and evaluate both Foucault’s passage from archeology to genealogy and the consequences.
It will be shown that while Foucault did not leave archeology in general, he concluded that the method of genealogy relates the changes in discursive systems to non-discursive acts. He gave an effective analysis of social structure of the power and, while preferring genealogy, he incorporated archeology into his whole research program, so that, given specific ambiguity in the definitions of the structures, elements, and limits of two methods, it is not baseless to emphasize on continuity of two methods in Foucault’s works.
