关于演绎推理的定义,在我圈现今的形式逻辑(指传统逻辑,下同)论著中,有两个定义广为流行。其一,“演绎推理就是前提与结论之间有蕴涵关系的推理”,其二,“演绎推理就是前提与结论之间有必然联系的推理”。本文拟对这两个定义发表不同意见,并最后论证笔者的观点:演绎推理就是前提与结论具有充分条件或充分必要条件必然联系的推理。
With regard to the definition of deductive reasoning, two definitions are widely prevalent in my current treatise on formal logic (traditional logic, the same below). First, “deductive reasoning is the implication of the implication between the premises and the conclusion,” and second, “deductive reasoning is a necessary reasoning between the premises and the conclusion.” This article intends to express different opinions on these two definitions, and finally prove my point of view: deductive reasoning is the reasoning that the premise and the conclusion have sufficient conditions or necessary and sufficient conditions.
