In a recent paper, Brian Rabern suggests a semantics for languages with two kinds of modality, standard Kripkean metaphysical modality as well as epistemic modality. This semantics presents an alternative to two-dimensionalism, which was developed in the last decades. Both Rabern’s semantics and two-dimensionalism are subject to a puzzle that Chalmers and Rabern ( Analysis, 74 (2), 210–224 2014 ) call the nesting problem. I will investigate how Rabern’s semantics answers this puzzle.

Rabern 的形而上学和认知模态语义以及嵌套问题

在最近的一篇论文中，Brian Rabern 为具有两种模态的语言提出了一种语义，即标准的克里普克形而上学模态和认知模态。这种语义提供了二维主义的替代方案，后者是在过去几十年中发展起来的。Rabern 的语义和二维主义都受制于 Chalmers 和 Rabern ( Analysis, 74 (2), 210–224 2014 ) 称之为嵌套问题的难题。我将研究 Rabern 的语义如何回答这个难题。
