二难推理需要遵守选言推理的规则吗?

Should Dilemma Observe the Rules of Disjunctive Syllogism

无论是从推理机制还是从前提构成看,二难推理实质上都属于充分条件假言推理因而需要遵守充分条件假言推理的规则。所谓二难推理属于选言推理因而需要遵守选言推理规则的说法是不能成立的。

Whether it is viewed in the light of inference mechanism or from the angle of premise constitution, in essence, dilemma belongs to fullconditioned hypothetical inference, and therefore should observe the rules of hypothetical inference, the socalled argument does not hold water that dilemma belongs to disjunctive syllogism and should observe the latter's rules.
