在语义理解中,言说者(speaker)和诠释者(interpreter)之间信念的一致和真扮演着不可或缺的角色,如何达到语言理解主体之间信念的一致和真,不同的哲学家由于其本体论和认识论的依据不同而有着不同的主张。奎因和戴维森对此问题所持的哲学立场基本一致,即认为整体论(holism)和宽容原则(the principle of charity)在保证信念的一致和真中起着重要的作用。本文依据奎因和戴维森的论述全面考察整体论和宽容原则在语言理解中的作用,重点是通过揭示整体论和宽容原则在戴维森纲领(Davidson’s Program)中的全面运用来展示这种作用。 In semantic understanding, the consistent and true beliefs between the speaker and the interpreter play an indispensable role. How to achieve the same and true belief among the subjects of language comprehension? Because different philosophers Ontology and epistemology are based on different and have different ideas. Quine and Davidson hold the same philosophical position on this issue, that is, holism and the principle of charity play an important role in ensuring the unity of belief and truth. This article examines the role of holism and tolerance principles in language comprehension on the basis of Quine and Davidson’s discourse, focusing on revealing the full application of holism and tolerance principles in the Davidson’s Program.
