逻辑推理与语用推理的区别
逻辑推理
1.纯理性的思维活动
语用推理
1.理性思维同非理性的思维相结合
2.静态推导 3.只考察大小前提中的客体，不与主体关联
2.同语境相结合的动态推导 3.主体对象化与客体，同时客体又同化与主 体 4.既考察必然性又考察偶然性，在两者的有 机结合中把握结论 5.不一定着眼于客观性知识，不排除主观经 验附会

4.1 Cognition, Relevance and Abduction
• Sperber ＆ Wilson also repeatedly emphasize the importance of logical knowledge. • 语篇接受者从一个假设推导出另一个假设，直到 找到具有最佳关联性的结论。语用推理过程中运 用的推理规则是演绎规则。 （Sperber＆Wilson,2001) Although Sperber＆Wilson emphasize deductive reasoning in pragmatic inference, the process of inference also covers abductive reasoning.
According to Jiang Yan (2002), inferential mechanism of verbal communication can be decomposed as the following: the speaker can establish the relevance of an utterance by a. searching for maximal contextual effects b. minimizing processing efforts

3.Features of Pragmatic Inference
a
The process of inferential communication is non-demonstrative. The process of inferential communication is “global” as opposed to “local”. Inference is instantaneous and spontaneous.
b. New Zealand is a very beautiful and rich country. I’m a New Zealander. ( activates the background knowledge stored in A’s mind) c. New Zealand is famous for its Maori culture. d. Nearly all New Zealanders love rugby crazily.

• Therefore, we can see from the above details that the kind of logical inference in Relevance Theory involves abductive reasoning as well as deductive reasoning, but Sperber＆Wilson do not clearly point out abduction.

4.2 The Dynamic Model
Testify whether this newly drawn conclusion is true or false. During the process of inductive reasoning, the reasoner also refers to the dynamic context and new information given by the context. The reasoner regards the conclusion draw from abductive reasoning as the major premise and the proposition decoded from the ostensive utterance as the minor premise, draw a new conclusion: positive or negative. Stimulated by some surprising facts or utterances and active encyclopedic knowledge stored in human mind.

4.1 Cognition, Relevance and Abduction
Logic is regarded as the study of valid inference. Inference means forming a conclusion from premise. And the utterance interpretation is also to reach a conclusion from the speaker’s utterance, which is also through the hearer’s inference.
