摘要
现行普通逻辑理论把二难推理的假言前提局限于充分条件假言判断和必要条件假言判断 而把充要条件假言判断排除在外 ,从而遗漏了一部分有效式 本文在这方面作一定的探讨 。
According to present Universal logic theories,the hypothetical judgment premise of the dilemma is confined to hypothetical judgment under adequate conditions and hypothetical judgment under necessary conditions.Hypothetical judgment under sufficient and necessary conditions has not been taken into consideration.As a result,some tautological forms of inference are left out.In this essay.I explores the aspect mentioned above and summarizes all the tautological forms of inference of the dilemma.
