【摘要】：传统逻辑的对当关系及其推理，，只与两个问题有关：１．Ａ、Ｅ、Ｉ、Ｏ四种命题是否为同素材的命题？２．它们是否既真在质上又真在量上？而与它们的逻辑变项是什么样的词项无关。现代逻辑在这两个问题上都存在着问题，其根本原因是不愿承认下面的事实：当主词Ｓ（或┓Ｓ）为空词项时，在Ｓ∩┓Ｐ和Ｓ∩Ｐ（或┓Ｓ∩┓Ｐ和┓Ｓ∩Ｐ）两个交集中，必有一个是有相同元素“φ”的特殊的存在集，并非都是没有相同元素的不存在集（或空集）。
[Abstract]:There are only two questions related to the traditional logic's relation and reasoning: 1. Are the four propositions of "A" and "E" / I _ (O) the same material? 2. Are they both qualitative and quantitative? It has nothing to do with what their logical variables are. Modern logic has problems with both of these problems, the underlying reason being the reluctance to admit that when the subject S (or S) is an empty word, There must be a special existence set with the same element "蠁" in the two intersection sets of S 鈮
