ABSTRACT :Universalization is a fundamental concept in philosophy that seeks to understand the nature of ideas and concepts that are applicable to all people in all places in the world and at all times. It is an approach that seeks to find principles and truths that are universally valid, regardless of any specific context. The concept of truth involves many philosophical reflections and discussions, throughout the history of philosophy, from classical antiquity to modern philosophy, so we will understand very relevant philosophical concepts: truth, lying and knowing. For the writing of this article, an analysis of the respective concepts was made, as well as the concepts of reality, objectivity, ethics, justice, politics, as well as their relationship with the different information and communication technologies, dissemination of sensationalist information, in the promotion of post-truth and the reflection on how philosophy can be used as a critical instrument in the valorization of universal truth. Human beings seek to have solid beliefs and life patterns based on truth, as a form of emotional and mental stability, for the understanding of universal reality and the making of conscious, ethical and responsible decisions. The human being, based on his knowledge, reflects on these questions, through critical exercise, as a way of dealing with the crisis of truth in an ethical and conscious way.
