How fictional works are related to fictional entities

The paper attempts at yielding a language-independent argument in favour of fictional entities, that is, an argument providing genuinely ontological reasons in favour of such entities. According to this argument, ficta are indispensable insofar as they are involved in the identity conditions of semantically-based entities we ordinarily accept, i.e. fictional works. It will also be evaluated to what extent this argument is close to other arguments recently provided to the same purpose.
