在向初学者教授符号逻辑的过程中,从非正式的“如果……,那么……”的共同话语结构过渡到根据物质蕴涵及其真值表进行分析的过程中遇到困难是一个屡试不鲜的经历。“如果p,那么q”必须理解为“如果p/T1,那么当q/T时,我们必须有(p、q)T,当q/F时,我们必须有(p、q)/F”,这个想法没有问题。因此,把解释引向正题是没有问题的。
In teaching symbolic logic to beginners, it is a not infrequent experience to encounter difficulties in the transition from the informal “if …, then …” construction of common discourse to its analysis in terms of material implication and its truth-table. There is no trouble with the idea that “if p, then q” must be so understood that “if p/T1, then we must have (p⊃q)T when q/T, and (P⊃q)/F when q/F. There is thus no problem in leading the explanation to the point.
