In relation to this subject it is necessary we reflect about the several questions that compound the reflection center of our author. We can show the theree ways the theme presents: the first accompany the historic-philosophical evolution of the hermeneutics problem; the second triest to the several onthologic problems studied by Heidegger and that contribute fundamentally with the Gadamerâs reflection, where the conductor string is the language. In this sense, the philosopher proposes the hermeneutics as onthology. The third way consists on the synthesis of the gadamerian thinking, where is need to show that the hermeneutics cannot be understood as a simple interpretative method but as an way of being of the comprehension as a whole. We can understand, finally, the hermeneutics as a live themathization of the historic phenomena which determine the dialogical relationship I â world, as growth and continuos development of their respective subjects. / The goal of this dissertation is the compreension of the concept Hermeneutics inside the thiking of Hans-Georg Gadamer and the relation between language and comprehension.
