Modal realism

Modal realism is a philosophical position according to which - according to widely accepted background assumptions - the truth makers of modal statements (statements with modal operators such as “possible”, “necessary” and “contingent” ) are facts in possible worlds that are just as real as the actual world . The expression “actual” is mostly understood indexically , ie it refers to the world of the respective subject. The most important and best-known representative of modal realism in recent systematic ontology is David Kellogg Lewis .
