至于通过论据或明显的论据而奏效的说服：正如在辩证法中一方面有归纳推理，另一方面有三段论或明显的三段论一样，在修辞学中也是如此。

With regard to the persuasion achieved by proof or apparent proof: just as in dialectic there is induction on the one hand and syllogism or apparent syllogism on the other, so it is in rhetoric.

很少有能够形成修辞学三段论基础的“必要”类型的事实。

There are few facts of the "necessary" type that can form the basis of rhetorical syllogisms.
