Analysis On Aristotle’s "Rhetoric Inference"

All the time since, few people concerned Aristotles "rhetoricinference" of “rhetoric” in logic, research achievement about it alsohasn’t become a system. but in fact," rhetoric inference" as a part ofAristotles logic system, as one of the most important part in "rhetoric", its28types both apply and supply Aristotles traditional logic，also containa thought beginning of modern language logic. This article takes28types of "Rhetoric inference" as the object of research, discussing its richconnotation.In" rhetoric inference" communicative function part, this paperanalyzes the "rhetoric inference" in communicative factors, includingspeech, the speaker and hearer theme, and clearly " rhetoric inference" integral inference properties: it is a kind of probability inference. Thisprobabilistic inference is mainly manifested in the premise of probability.Then, pointed out that " rhetoric inference" premise probability isdivided into two kinds, one is self-reference premise probability, theother is example premise probability. Example premise includes bothauthoritative opinion and fact views." Rhetoric inference" is probable,but it can achieve the persuasive effect, which is different fromtraditional logic syllogism that reasoning pursuit must really, but thesame as informal logic and critical thinking. It is extremely modern.In" rhetoric inference" Argument function part,28types of "Rhetoricinference" include a lot of reasoning, such as conceptual andreasoning by using.In conceptual by using, Aristotle demonstrates anew demonstration mode. In the traditional logic term inferences are often from syntactic aspects, by using the concept of the epitaxialrelationship and judgment in this reasoning. But here, Aristotle gives anadvantage to concept semantic aspects of the relationship betweenthe mode of reasoning. This reasoning method in todays traditionallogic we did not inheritance, in fact it is very worthy of attention anddevelopment. This part is a continuation of Aristotles traditional logicthought, inference method according to the word of the samemeaning and multilayer meaning is built on" topics" discussion andargumentation related content foundation, which also confirmedAristotle’s statement in the first proposed, which is " rhetoric is dialecticcounterpart." In reasoning by using,28types of "Rhetoric inference" notonly related to the hypothetical inference modus ponens, hypotheticalreasoning Modus Tollens and two difficult inference, in the hypotheticalreasoning Modus Tollens part also involves direct negation and indirectnegation two demonstration model. Also,"Rhetoric inference" givesthree different types of metaphor and demonstration, includingmetaphor, metaphor, metaphor and other characteristics of simpleevents.In" rhetoric inference" persuading function part, this paper mainlyuse the speech act theory to study. This paper presents the verbalcommunication of fundamental mode and the compound modewhen using of" rhetoric inference" in communication, and therealization of " rhetoric inference" persuading function is consistent withthese two modes, which means that " rhetoric inference" is extremelymodern.Therefore, this article made a detailed and comprehensive studyabout28types of " rhetoric inference", and concluded that " rhetoricinference" is important component of Aristotle’s logical thought, itscontent is extremely modern.
