摘要：

推理的全部前提可以看作这一推理的预设。日常的具体推理往往是省略的推理, 有些前提并未明确给出, 在这种情况下, 对预设作全面的分析就尤为重要。与此相关, 考察经典逻辑和模态逻辑中的某些推理规则, 讨论这些推理规则在日常推理中的有效性问题, 是十分必要的。

关键词: 预设, 推理, 推理规则

Abstract:

All premises of an inference can be regarded as presuppositions of the inference. Inferences in daily life tend to be expressed in omitted forms, where some premises are not explicitly given. Accordingly, it is very important to analyze presuppositions in an all - round way. This paper also explores some rules of inference in classical logic and modal logic, and discusses the validity of these rules of inference in daily life.

Key words: presupposition, inference, rule of inference
