## Abstract A survey of the isomorphic submodels of __V__~Ο~, the set of hereditarily finite sets. In the usual language of set theory, __V__~Ο~ has 2^β΅^0 isomorphic submodels. But other setβtheoretic languages give different systems of submodels. For example, the language of adjunction allows only

In this paper the existence of natural models for a paraconsistent version of naive set theory is discussed. These stand apart from the previous attempts due to the presence of some non-monotonic ingredients in the comprehension scheme they fulfill. Particularly, it is proved here that allowing the
