Driven by a double pursuit for the present (présent) and the autochthon (autochtone), Michel Foucault arrived at conceiving a radical critical philosophy illuminated by archeology and genealogy. On the one hand, it approaches the being of language itself through the archeology of discursive events. On the other hand, the being of subjectivity itself is revealed by the genealogy of the transformation of Self. In both cases, an analysis of the farm of immanence is involved. This text attempts to analyze, or precisely to schizo-analyze, this plan of immanence, created by Foucault through these two particular movements of thinking. The complicated late-foucaldian conception of the gaze upon self or the transformation of subject will be another focus of investigation
