三段论和归纳法在亚里士多德哲学和修辞学中的不同运用

三段论和归纳法在亚里士多德的思想体系中具有两种完全不同的运用：在哲学中归纳法为三段论提供真实必然的初始前提，三段论保证推理过程的必然性，其结果是科学知识；在修辞学中，归纳法表现为例证，三段论表现为论证，两者都不要求必然性，其结果是说服。亚里士多德对于三段论和归纳法的两种运用确立哲学和修辞学的紧密联系，促进了修辞学的诞生。

On the Different Uses of Syllogism and Induction in Aristotle＇s Philosophy and Rhetoric

Syllogism and induction have two kinds of different uses in Aristotle＇ s ideological system. In phi- losophy, induction provides genuine necessary premises for syllogism, syllogism guarantees the inevitability of reasoning process, and the result is scientific knowledge. In rhetoric, induction manifests as exemplification, syllogism manifests as argument, both of which need no inevitability and the result is persuasion. These two kinds of uses by Aristotle have established a close relationship between philosophy and rhetoric and resulted in the birth of rhetoric.
