摘　　要： 形式逻辑的最小单位是命题,其基本特征是判断性和真值,因此排除了语句可能具有的真假程度性。形式逻辑核心任务在于区分有效论证和无效论证。它完全排除语境因素,而语言学则将语境作为其研究的基础,因此在研究诸如if条件句这样的自然语言现象时采用形式逻辑系统所做出的结论,对于相关语言学研究的指导意义不大。 Formal logic operates on its minimal units of propositions, which are characterized by assertiveness and truth - value regardless of possible degrees of truth or falsity embodied in natural - language utterances. It aims, as its primary disci- plinary mission, at verifying or attesting the validation or invalidation of inference. Formal logic entirely precludes from it the linguistic contexts, which serve as the very basis linguistics proceeds from. Consequently, the conclusions drawn from the researches on such natural - language phenomenon as if - conditionals based on concepts of formal logic would seem implausible in their directive essence.
