因明入正理論疏 2.64

2.64

述曰：比量體者，謂證、敵者，籍立論主能立眾相而觀義智。宗、因相順，他智順生；宗既違因，他智返起，故所立宗名比量相違。此中意言：彼此共悉瓶所作性決定無常，今立為常，宗既違因，令義乖返，義乖返故，他智異生，由此宗過名比量相違。

The Commentary explains: As for the essence of inference (anumāna), it refers to the cognition by which the umpire and the opponent examine the meaning by relying on the various characteristics of the proof of the proponent. When proposition and reason accord with each other, the other's cognition arises in accordance; since the proposition here contradicts the reason, the other's cognition arises in reverse, so the posited proposition is called "contradiction with inference." The meaning intended here is: both parties mutually know that the jar's nature of being produced is definitely impermanent; now to posit it as permanent, since the proposition contradicts the reason, causes the meaning to be contrary; because the meaning is contrary, the other's cognition arises divergently; hence this fallacy of the proposition is called "contradiction with inference."
