中文摘要:

在日常语言中,语句must φ的强度弱于φ,这不同于通常模态逻辑对认知模态词must的解释,是有待解决的Karttunen问题。基于Stone和von Fintel与Gillies的理论,本文指出:形同must φ的语句不仅体现说话人对命题φ真值的判断,亦能表达说话人判断φ真值时具有的证据并非“一手证据”。说话人对φ真值的判断取决于说话人拥有的证据集合,以及证据集合中元素对命题φ的支持程度。这种对must形式语义的新解释,能够说明must φ在何种意义上比φ更强或更弱,从而为Karttunen问题提供新的解决方案。

外文摘要:

In ordinary language, the strength of the sentence must φ is weaker than that of φ, which is different from the modal logic interpretation of the epistemic modal operator must, which is the Karttunen's Problem to be solved. Mainly based on the view of Stone and von Fintel and Gillies, this paper argues that sentences in the form of must φ not only reflect the speaker's judgment on the truth value of the proposition φ, but also express that the evidence the speaker has when judging the truth value of φ is not the first-hand-evidence. For the speaker, the truth value of φ depends on the evidence set that the speaker has, and the degree of support of the elements in the evidence set to the proposition φ. This new interpretation of the formal semantics of must is able to show in what sense must φ is stronger or weaker than φ, thus providing a new solution to Karttunen's problem.
