"Following Kant, Foucault criticized the practices that impede maturity, issuing a powerful warning against blind submission to the will of authorities. With Kant, he also insisted that the subject has a “right to question truth concerning its power effects and to question power about its discourses of truth”. Indeed, Foucault notes that his view of critique resembles Kant's idea of enlightenment: both involve “the art of voluntary inservitude, of reflective indocility”. For Foucault, moreover, philosophy as a whole exemplifies this art. The history of philosophy is a history of parrěsia, of the courageous practice of speaking truth to power. By the end of his regrettably short life, then, Foucault recognized that he belonged to the tradition of critical philosophy that runs from Kant and Hegel “to the Frankfurt School, passing through Nietzsche, Max Weber and so on”. As a critical thinker, he promoted maturity by encouraging his readers to engage in sustained – critical and self-critical – reflection on the historical conditions that have made them what they are. For by understanding how they are entangled in these conditions, readers might be able to rise above them and resist them. And, for Foucault, whatever freedom we can meaningfully be said to possess consists in resistance to prevailing forms of power."
