当代条件句逻辑面临的困境与出路

The Dilemma and Outlet of Contemporary Conditional Logic

当代关于条件句的理论很多,我们很难从总体上对其进行完全的把握,但是,以是否把条件句作实质蕴涵的解释,我们大体上可以把它分为两类:实质条件句进路与非实质条件句进路。这两条进路从不同的视角解释了条件句,它们各具特色,都具有一定合理性,但它们又都存在一些困难。在对这两条进路进行分析的基础上,我们尝试对条件句逻辑发展前景进行展望。

The many conditional theories at the contemporary times make it hard for us to have an overall grasp of them. According to whether conditionals can be taken as material implication, however, we can generally divide them into two categories：the material conditional approach and the non -material conditional approach. The two approaches explain the conditionals from different aspects. Both have different characteristics and are reasonable to a certain extent. But both have difficulties in explaining the conditionals. On the basis of the analysis of the two approaches, we try to prospect the logical development of conditionals.
