This paper is an invitation for think the recent and next decades in the space of humanities and social sciences, and philosophy more involved in this, from the Foucault´s work, to the thirty years for your decease. My interest is the deepen-ing at the same time in two complementary directions: the philosophical task in dialog with contemporary ethnographic work. From this attitude I considered the main keys of your thinking. For this, first, I propose the type of approach considered like opportune. In second term, I expose a synthesis the gnoseological approach of analysis of processes of subjectivation, for to arrive in third term to final considerations about the study of problematization ways, like “ontology of the present or ourselves”. From this, I pretend to extract the more important considerations for the task of investigation the contemporary subjectivity.
