Abstract
This article focuses on the concepts Foucault devices and self care. The conduct of the work develops the paths that led Foucault to this theoretical movement, seeing in this modulation important ethical and political implications in the theoretical course of the author but also - and greatly - as everyday weapon for fighting the increasingly detailed contemporary battles. Diverted from the explicit context in which emerges to the public - in the last two volumes of the History of sexuality - and put under a larger view - as it appears in the Collège de France courses and some interviews - the bet is that the concept of care of itself can also leave worries the researchers of the present.
