Da ética do dever-ser a ética do diálogo

This paper intend to demonstrate the apparent contradiction of Hegelian thought. Hegel's attempt isto unite with the substance of Spinoza and whit the “I free” of Kant, in other words, necessity andcontingency. As we know this project is unfinished, and a modal operator, ie, a “must be” cosmicbeing weaker than the “must be” Kantian permeating the whole system, does not resolve thisquestion.To reflect about this problematic leads us to the concept of ethical dialogue in Gadamerand you can take us toward an intersubjective ethical structure. Therefore, one must postulate suchquestion “ab initio’ to justify the way of this argument, recognizing that this dimension of the humanmeeting, advocates the dialogue as a hermeneutical core of this ethical structure. In Gadamer thereis an invitation to a recognition of what is at stake: the dialogue. On the horizon of hermeneuticperspective, the dialogue is in a praxis, a fundamentally ethical stance.
