Natural logic, model of values exchange and ethics of discourse
Communication has biological and historical roots. It is previous to the possibility of scientific knowledge and, as such, crosses philosophy, the arts and the lived world. We have no choice than thinking of it in a very broad way. In methodological terms, transversality is provided by looking at communication as language in its multiple forms, as well as action and development along time. In this sense, we integrated methods coming from three authors. Our first step is applying natural logic developed by Jean-Blaise Grize, associated with Jean Piaget's model of values exchanges. Such approach allows us to study natural discourse in order to describe communication processes that develop over time. Then, we assess the ethical dimension of discourse by adopting a critical approach inspired in Habermas's work. The integration of these methodological perspectives enable us to study communication as a psychological, socio-political, as well as moral-ethical process.
