Compossibility
（重定向自Compossible）
Compossibility is a philosophical concept from Leibniz. According to Leibniz a complete individual thing (for example a person) is characterized by all its properties, and these determine its relations with other individuals. The existence of one individual may contradict the existence of another. A possible world is made up of individuals that are compossible — that is, individuals that can exist together. Leibniz indicates that a world is a set of compossible things, however, that a world is a kind of collection of things that God could bring into existence. For not even God can bring into existence a world in which there is some contradiction among its members or their properties.
