[Intersubjectivity: Between Explanation and Understanding]

The discussion on explanation and understanding has led to a division in the sciences, based on what is considered to be inherent to each of the domains. The task of the natural sciences would be the explanation, while that of the social sciences would be understanding or interpretation.There is a line of work that currently seeks to overcome the methodological dualism and to propose more interdisciplinary studies, such as the studies on emergence of the mental in the framework of intersubjective relationships. In particular, the concept of intersubjectivity defended by the phenomenology as an embodied practice, is being supported by the results of investigations carried out on the basis of the cognitive neuroscience and developmental psychology. Authors from different roots, such as J. Bruner and S. Gallagher propose considering these types of interdisciplinary collaboration as a possible way to integrate the traditions of the explanation and understanding. The purpose of this paper is to analyze to what extent this collaboration between phenomenology and sciences, particularly on the subject of understanding others and their relevance for the understanding of certain psychopathologies, has allowed to close the gap that had opened in the nineteenth century between these traditions.
