蕴涵刍议

实质蕴涵与否定、合取、析取、等值等其他逻辑联结词一样, 其实质是对自然语言中复句的关联词所进行的合理的逻辑抽象, 所谓的&;#1048577; 实质蕴涵怪论&;#1048577;其实并不怪, 它是人们要求实质蕴涵反映条件联系中除真假联系之外的内容、意义方面的联系, 从而作了错误的解读所造成的; 作为一种特殊的条件语句, 在反事实条件句与实质蕴涵的关系问题上, 在反事实条件句与一般性条件句的区分上, 还有很多地方需要进一步探索。

On Implication

Material implication,like other connectives such as negation,conjunction,disjunction and equivalence,is the logical abstraction from conjunctions of compound sentences in natural languages.The so-called paradox of material implication is not actually that odd since it is caused by some kind of misunderstanding when people require material implication expressions not only the truth properties but contents and meanings as well in conditions.As regards material implication,such as a particular expression of condition,some further studies are needed to explore the relations between anti-fact conditions and material implications,and the distinction between anti-fact conditions and ordinary conditions.
