Ersatz world, philosophy: expression from David Lewis for possible worlds which consist only of sets of sentences, as opposed to worlds (different from our actual world) that are really existing. Other authors such as S. A. Kripke believe, unlike D. Lewis, that possible worlds do not really exist but are only construed for theoretical reasons. See also ersatzism, modal realism, possible worlds, metaphysics, necessity, essentialism, telescope theory._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Hartry Field on Ersatz Worlds - Dictionary of Arguments
I 226 Ersatz worlds resp. "Ersatz individuals"/Field: i.e. in Stalnaker's way of speaking: "To show how the world could be or could have been". That is, maximally determined properties that an individual might have or might have had in the universe. This can be used to define cross-world congruence. Cf. >Cross world identity. Then "Ersatz matter particles" are properties! Then "congruent" and "between" are higher-order predicates that are applied to properties. >Properties, >Predicates, >Second order logic, >Description levels/Field. Whereby xP is also an ersatz particle, one that is instantiated in the real world by the normal particle x. x is a normal particle, but the "ersatz particle" that corresponds to it, and by which conge and bete are defined, is a property, a "way like x could be" and actually a way how x is up to date. ((s) Ersatz-individual: here not a particular but a property, a "way".) Field: but this does not help relativism (the thesis that empty space is possible) either. >Relativism, >Relationism, cf. >Substantivalism._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
