Michel Henry questions the opposition body - flesh as indebted to the opposition between what appears / the appearing, under the light of what he calls "The reversal of phenomenology", i.e. "the substitution of the phenomenology of the world for a phenomenology of life". This question raises another question: the constitution of intersubjectivity, which this article is trying to answer by developing a schema of intersubjectivity through a critical rereading of the theory of Nietzsche about active force and reactive force.
