中国古代有逻辑思想,但没有逻辑学——答马佩教授

广义的思维形式即思维形态不是逻辑学的研究对象,狭义的思维形式才是逻辑学的研究对象,就传统逻辑而言,狭义的思维形式是用概念变项或命题变项代替思维形态中的具体概念或具体命题的结果。由思维形态构成的理论是逻辑思想,逻辑思想是从逻辑思维发展为逻辑学的中介环节。名辩理论的出现证明中国古代有逻辑思想,不足以证明中国古代有逻辑学。

There was Not any Logical System but Logical Thought in Ancient China——A Reply to Ma Pei

The object of logic study is the specialized form of thinking instead of the generalized form of thinking,that is,formation of thinking.As far as the traditional logic is concerned,the specialized form of thinking results from substituting the conception variables or propositional variables for the concrete conceptions or propositions in the formation of thinking.Logical thought is a speculation on the formation of thinking,which is merely an intermediary from the logical thinking to the logical system.What the so-called Ming-bian "logic" witnesses is not that there was any logical system in ancient China,but that there was some logical thought in ancient China.
