In the present work is addressed three defining aspects of the question hermeneutics as didactic and condition to generate a shared horizon of meaning. In the first place the dialog between the text, author and reader. Second, the opening of the horizon of meaning through the question and its radical ontological. Third, the role of tradition in the construction of rational discourse and breaking through a language polysemic. Finally, we conclude that the dialog that opens horizon and shared sense is (...) the only capable of building long-term consensus and, specifically, solutions. (shrink)
