This text, originated from my Master's thesis, aims to dissertate on genealogy as methodology, according to Michel Foucault's proposition. In this approach, the archeological analysis of the speech is understood as the foundation supporting genealogy by suggesting the description of the field as a net formed in the inter-relationship of the several knowledge present, which makes possible the discourse emerge according to our concept. The genealogical approach searches for the origin of the knowledge through the factors interfering in their emergence, maintenance and suitability to the discursive field, as elements included in a political speech opening the conditions to enable the individuals to be immersed in given discursive practices.
