Abstract

In recent decades, the problem of post-truth has emerged. Values such as fairness, objectivity, and critical dialogue have become more difficult to achieve. Various characteristics are associated with this, such as the emergence of new technologies and a new era in political relations with the rise of fundamentalism and populism. Besides, the reference to postmodernism is always commonplace in the bibliography on the subject. Considering this, the article’s main objective is to philosophically analyze the theoretical foundation of post-truth, postmodernism. From the methodological point of view, this theoretical study will take the interpretive approach as a reference. Interpretive hermeneutical criticism has been combined with a documentary analysis of the main works that address this problem. The article explains the main characteristics of the concept, considering the current and notorious interpretation, and then interprets the position that criticizes postmodernism as the theoretical basis of the post-truth era. It concludes by defining that the relationship between post-truth and its theoretical foundation has a dogmatic and contradictory character since it confronts subjectivist relativism with the dogma of a realist metaphysics.
