Reism

Reism, reificationism, concretism or concretionism is a view that only concrete material things exist. It is a philosophical theory associated with Tadeusz Kotarbiński who proposed that it involves both the proper view about the kinds of objects that exist and the literal way of speaking about things. It is based on the ontology of Stanisław Leśniewski, specifically, his "calculus of names". This theory, which is also referred to as somatism and pansomatism, has been interpreted as an analogue of defended classic physicalism.
