Scientific Essay from the year 2010 in the subject Philosophy - Philosophy of the 20th century, , language: English, abstract: the present study engages with the questions of subject and the activity of truth-telling in the context of the problem of language that frequently appears in Foucault since his appearance in French academics. It asks the questions: what is the mode of existence of language and being in Foucault and how are they related? What is a sign? Can one actually understand a sign in itself? If neither the cogito (I think) can lead to an affirmation of being, nor the affirmation “I speak” has it the autonomy to stand on its own, how one can relate oneself to truth?
