本文以塞尔的意向性理论为基础,探索规约性翻译理论命题的论证逻辑,说明经验实证在规约性翻译研究中的作用及其限度。论文指出,规约性翻译研究命题其意不在于描述事实,而在于规定或引导行为。对于此类命题,我们要论证的不是其是否为真,而是其是否合理。规约性翻译理论的合理性论证必须包含两种要素:因果性要素与价值性要素,前者可以通过实证性研究得以验证,而后者则超出了实证性研究的验证范围。对于规约性翻译研究而言,经验实证是有意义的,但这种意义同时也是有限度的。 Based on Searle’s Intentionality Theory, this article explores the logic of argumentation of the propositions of the contracted translation theory and illustrates the role and limitation of empirical evidence in the study of the contracted translation. The dissertation points out that propositional translation studies are not intended to depict facts but to regulate or guide behavior. For such propositions, we should argue whether it is true or not, but whether it is reasonable or not. The justification of the theory of contractual translation must include two elements: the causal element and the value element. The former can be verified through empirical research, while the latter goes beyond the verification scope of empirical research. For empirical translation studies, empirical evidence makes sense, but at the same time there is a limit to what this means.
