This paper studies the relation between dialogue, truth and communication in Plato's thought and the similarities between Plato's theory of language and some philosophers of the twentieth century like Heidegger or Gadamer.

This work considers Heidegger's treatment of Aristotle's doctrine of logos apophantikos. Through a singular interpretation of Aristotle's De Interpretatione, Heidegger rejects the traditional notion of truth as "adaequatio" that takes place in judgement to offer an alternative comprehension in terms of unconcealment.
