关于真值载体的再思考

Reconsideration on the Conception of Truth-bearers

真值载体是哲学和逻辑学的重要概念,围绕着真值载体,国内学术界分别形成了命题说和语句说两种不同的理论。这两种理论的纷争起源于弗雷格和蒯因。从弗雷格和蒯因各自的哲学体系和逻辑观念出发来审视他们关于真值载体的理论和看法,对评判命题说和语句说的得失而言,是一种有益的视角。对于哲学追求对世界的普遍理解的目的而言,对真值载体的不同回答,预设并体现哲学家们关于意义、同一以及言语行为等概念的不同理解,真值载体因而是哲学的重要而核心的问题;而对于现代逻辑追求真的普遍性的独特目标而言,真值载体是重要问题,但不是核心问题。

The notion of truth-bearers occupies an important role both in philosophy and logic.Surrounding this concept,there are two dominant yet opposite theories in China：the proposition theory which regards propositions as the bearers of truth and the sentence theory which regards sentences as the bearers of truth.These two theories stem from Frege and Quine.It will be a beneficial perspective for these two theories to reconsider on Frege＇s and Quine＇s viewpoints on the concept of truth-bearer in the circumstances of the truth theories of each of their own.For the special purpose of philosophy to pursue the general understanding of the world,the problem surrounding truth-bearers is an important and central issue,for the controversy about truth-bearers by philosophers is ultimately originated by their different understandings of meaning,identity and the act of speech.For the special purpose of logic for the pursuit of the generality of truth,the question surrounding truth-bearer is an important one,but not a central issue in logic.
