The article intends to show the creative power of the concept of device in Foucault's problematization of the subject. In this sense, at first, it analyses the way Foulcault conceives the subject as historically constituted in terms of subjection to the meshwork of knowledge and power of a device. Then, it highlights the inflection that occurs in the referred problematization, which leads to consider subjectivation as a practice of freedom, i.e., as a limit-experience operating in the boundaries of a device. Finally, it proposes that cartographing a device consists in outlining the agonistics of subjection/subjectivation that transverses a subject.
