《普通逻辑》二十五年回望

普通逻辑应以传统逻辑的精华为其主体 ,适当吸收数理逻辑的基础知识 ,形成二者融合的教学体系 ;逻辑形式中不仅应包含有演绎推理 ,而且应包含归纳推理 ;三段论规则可以区分为构造规则、一般规则和导出规则 ,它们在层次上是不同的 ;矛盾律与排中律的适用范围并没有宽与窄的区别 ;充足理由律可以保留 ,但它不是普遍的逻辑规律 ,而是论证的规律 ;在论证中 ,应当把论证方法与论证规则协调起来 ,以消除逻辑矛盾

General Logic in the Past 25 Years

General Logic is a pedagogical system syncretized the essence of traditional logic with some fundamental knowledge of mathematical logic. The logical form contains not only deductive reasoning, but also inductive reasoning. The syllogistical rules may be analyzed into constitutive ones, general ones and educed ones, which are stratified differently. The laws of contradiction and excluded middle concerns no broad or narrow distinction in regard to their application scope. The principle of sufficient reason may be reserved, but it is not a common logical law, but one of argumentation. And it should harmonize argumentation methodology with argumentation rules to avoid logical contradiction.
