变形推理疑难解惑——兼析逻辑与经验之差

The Solutions to the Difficulties of Transformed Reasoning

按规则对直言命题进行变形推理,会出现结论违背经验常理的情况。探索其根源,是经验思维中对对象域的把握与逻辑对对象的抽象设定不一致所致。为消除直言命题变形推理出现违背经验常理的情况,使经验与逻辑统一起来,必须限定“每次对命题变形不得转移主项或谓项的论域”。

The deviations from the natural conclusion will arise when categorical proposition is reasoned in transformed forms. It is found out that the disagreement between the object of experimental thinking and that set by logic reasoning is the root of the deviations. To solve the problem, it is necessary to follow“ it is allowed to change the scope of subject-predicate, or predicate”.
