Foucault or political scepticism obeys a research project that aims to link sceptical thought, understood as a Western philosophical operator, with the working hypotheses that occupied the French thinker, which were contained in the speculative referrals between power, truth and the subject. In this sense, the research proceeds to break down, analytically, the specific treatment that Foucault has with truth, this from three instances: the epistemological, the ethical and the political. The backdrop to this analysis, the contextual atmosphere if you will, is provided by phenomenology, given that a good part of the 20th century was marked by the approaches of Edmund Husserl, approaches from which Foucault derives through the critique of meaning, which has strong repercussions on the constitution of subjectivity through the force of truth. All of the above allows us to argue that Michel Foucault's thought entails a kind of political scepticism, since it critically shows the effects of power that bind truth to subjectivity.
