Philosophy is that which calls into question domination at every level and in every form in which it exists, whether political, economic, sexual, institutional, or what have you. To a certain extent, this critical function of philosophy derives from the Socratic injunction “Take care of yourself,” in other words, “Make freedom your foundation, through the mastery of yourself”.
