We explore on this essay the place of sociology in the path and in some works of Michel Foucault, comparing the references that the French philosopher made along his work to the science of society and some sociologists. The sociology emerges in the analysis of the author as a side issue, linked mainly to the question of the emergence of the human sciences and the transformations of power economy in modern societies. The article also proposes to conduct a reading of Foucault's thought, explaining the similarities and theoretical implications, conceptual and thematic with sociology. Finally, we discuss the presence of Foucault in contemporary sociology and how some of the most important current sociologists have referred to his work.
