Considering the most important criticisms to the theory of transworld individuals as well as some problems related to origin essentialism, this article addresses the issue of the identity of those individuals across possible worlds. We propose the notion of admissible world as a special type of model in Intensional Logic, which, within another model, allows mapping the history and identity of individuals in different possible worlds. This view suggests a plausible solution for determining the empirically relevant essential properties of transworld individuals, a useful method to assess their identity, and, finally, a new way of reexamining the classical debate between realism and anti-realism in the Philosophy of Language
Palabras clave : language; realism and antirrealism; admisible world.
