This dissertation investigates non-figurative discursive ways of presentation of pain to see, go on from there, the possible modalities of enunciation of self-expression that, even reacting to a crisis of representation, call into question a sense of real as unrepresentable. The study focuses on the writings of three authors in the twentieth century responded with different emphasis to the issue addressed here: Ludwig Wittgenstein, Antonin Artaud and Henry Miller. The issue that is shaping this work is caused by the predilection of Wittgenstein for the theme of pain in his Philosophical Investigations in the treatment of private language argument. Wittgenstein at this point calls for a reflection that addresses the manifestations of language related to pain, not being the representation of individual s inner world, constitutes behaviors exercised in specific language games that give them relevance. ―How I can even attempt to interpose language between the expression of pain and the pain? (PI, 245). First of all, it proposes a reflection that, from Wittgenstein s warnings, addressed to question a defense of the unrepresentable, looking for a reading of discursive modes of Wittgenstein s own for the presentation of occasions in which the expression of pain by language not being a representation is a behavior before the pain. And, secondly, a reading of works by Antonin Artaud and Henry Miller whose pain treatment, in view of this reading of Wittgenstein, presents discursive modalities engaged in a non-figurative expression and averse to a real sense as unrepresentable.
