This article presents a reading of how the relationship between health and the body has been mediated by the hegemony of a mutilating and mutilated view of the body that has dominated western thought and its hegemonic notion of science. We argue for the need to redefine this knowledge, which can be made possible, for example, by employing perspectives such as Edgar Morin’s theory of complexity, which postulates the need for a re-connecting of ways of knowing in science today. In associating the body and health, we attempt to show how important it is to Medicine and Physical Education that they enrich their approaches by incorporating the premises of existential phenomenology and human motricity.
