Abstract
The article critically examines the ideas of the Dutch philosopher and ethnologist Annemarie Mol. Her main work, “The Body Multiple: Ontology in Medical Practice”, is mainly subjected to analysis. According to the author of the article, A. Mol managed to offer his own version of the “ontological turn” and, perhaps, change the accents in the entire theoretical repertoire of actor-network theory (ANT). She, carrying out a “police investigation” in hospital Z, was able to show the multiplicity of ontologies of the body and its disease / illness. What is called the illness is represented by a large number of actors – people, their relationships, tools, diagnostic methods, etc. – which together can be represented as an assembly or assemblage. The “choreography of the ontology” of such an assembly is contingent, since it may be different.
