Abstract
The Foucault’s conception of power, so as those instructions that lead to think the body as a surface or exteriority, enable to suppose that body transcends the restrictive context with the one usually associated with. For that, it’s necessary to inquire into the Foucault’s form to think about the exteriority; principally the one that persists between visibility and enunciation. This subject will be analyzed starting from the multiples forms with which they appear in the foucaultian’s proposition, especially about the clinic and the explanation of the passage from classic to modern culture.
