摘要

在(Kosterec 2021)中,Kosterec试图为涉及正常模态算子$\Diamond$和$\square$以及虚构中的真(a la Lewis)算子$F$的某些论题提供“模型理论证明”,然后他继续展示了Kripke模型中的反例。他由此得出结论,在虚构真算子下嵌入模态逻辑是不健全的。相反,我们表明,“模型理论证明”本身是不健全的,涉及非法替代,这是一个微妙的错误,然而,它使我们能够得出关于内涵上下文(如虚构的上下文)和语义等价的重要结论。

Fictional Modality and the Intensionality of Fictional Contexts
In (Kosterec 2021), Kosterec attempts to provide ``model-theoretic proofs'' of certain theses involving the normal modal operators $\Diamond$ and $\square$ and the truth-in-fiction (`a la Lewis) operator $F$ which he then goes on to show have counterexamples in Kripke models. He concludes from this that the embedding of modal logic under the truth-in-fiction operator is unsound. We show instead that it is the ``model-theoretic proofs'' that are themselves unsound, involving illicit substitution, a subtle error that nevertheless allows us to draw an important conclusion about intensional contexts (such as fictional contexts) and semantic equivalences.
