论蕴涵命题的模态意义——兼论逻辑真理不能完全独立于经验事实之外

On the Modal Implication of Conditional Proposition——and That Any Logical Truth Can Not Hold on Absolutely without Considering Any Empirical Fact

作者分析了命题之真与假的逻辑意义,并通过n个合取与析取命题,分析了蕴涵命题的模态意义,由此,揭示出多种蕴涵命题的真值函项意义。基于此,讨论了诸多逻辑关系词的经验背境及其与对象世界的关系,并说明逻辑真理并非全是必然真理,可能真理也是逻辑真理。

This article analyzes the logical implication of proposition being true or false, and the modal implication of conditional proposition in form of n conjunctive or disjunctive propositions, in order to clarify the truth - functional signification of different kinds of conditional propositions. Then, it discusses a good many logical relations＇ empirical backgrounds and their connections with the object world. Conclusively, it illustrates that all logical truths are not necessary truths, and possible truths are also logical truths.
