摘要
“是而然”、“是而不然”是《墨经·小取》研究推论时提出的两种重要情况。“是而然”的形式可从语法形式与逻辑形式两个层面加以讨论。可以证明,“是而然”的逻辑形式是有效的,故“是而然”是有效的演绎推论。“是而不然”诸例看似与“是而然”相矛盾,其实深入分析就可发现,诸例严格来讲并不构成“是而然”模式反例,因此,“是而不然”的存在实际上不影响“是而然”式推论有效。
The Chapter of Xiao Qu in Mo Jing proposes two key conceptualizations for. the study of inference —— ＂Shi Er Ran＂ and ＂Shi Er Bu Ran.＂ The form of＂Shi Er Ran＂ can be studied both grammatically and logically. It can be proved that the logical form of ＂Shi Er Ran＂ is valid and thus ＂Shi Er Ran＂ is valid inference. Various examples of ＂Shi Er Bu Ran＂ seem to be in contradiction with ＂Shi Er Ran.＂ However, we can find through a thorough analysis that these are not true counter- examples of ＂Shi Er Ran.＂ Therefore, the existence of ＂Shi Er Bu Ran＂ does not affect the validity of the inference ＂Shi Er Ran.＂
