本文選題：性質命題　切入點：對當關系推理　出處：《安徽大學學報》1998年02期

【摘要】：傳統(tǒng)邏輯的對當關系及其推理，，只與兩個問題有關：１．Ａ、Ｅ、Ｉ、Ｏ四種命題是否為同素材的命題？２．它們是否既真在質上又真在量上？而與它們的邏輯變項是什么樣的詞項無關�，F(xiàn)代邏輯在這兩個問題上都存在著問題，其根本原因是不愿承認下面的事實：當主詞Ｓ（或┓Ｓ）為空詞項時，在Ｓ∩┓Ｐ和Ｓ∩Ｐ（或┓Ｓ∩┓Ｐ和┓Ｓ∩Ｐ）兩個交集中，必有一個是有相同元素“φ”的特殊的存在集，并非都是沒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
