The aim of this article is to discuss Michel de Certeau’s reflection on the feelings attributed to the body by Western culture, and to point out his reprisals for Christian religiosity. In methodological terms, attention was drawn to the interdisciplinary dialogues promoted by this author, who moved between the fields of psychology, history, linguistics, philosophy, theology and spirituality. As a first hypothesis, it is assumed that, for De Certeau, the body is a ‘fiction’ enabling social practices, that is to say, a body of ‘authority’ capable of provoking admissions, conflicts and transformations. This is because, according to this jeSwiss intellectual, the body is both a symbolic inputting of institutionalised powers, as well as mediation for DIY, embezzlement and political-cultural transgresses promoted in the cotidy. At the same time, it is considered as the second hypothesis that, as Mr De Certeau points out, the body in the Christian tradition has also been seen as a ‘misstic’ body, that is to say, for his manifestations, he lists the aninterior because he is inhabited by another/other. It is also suggested that updating this existential and political condition now makes it possible for individuals to position their intrinsic human incompleteness and fragility, thereby encouraging more sensitive and shared social and social experiences.
