论假言判断中的两个谬误

On Two Fallacies about Modus Judgment

尽管前人对假言判断作了比较深刻的研究,但仍存在疏忽。首先,定义缺乏严密的逻辑性,其次,把“充分必要条件假言判断”当作是假言判断的第三种形式,也不正确。

The article argues that the definitions about several forms of modus judgment are not scientific, they are short of strict logic, they are wrong. So new and scientific definitions should be given; it is wrong to regard so-called 'conditional modus judgment' as the third form of modus judgment, which should be cancelled.
