因明入正理論疏 3.238

3.238

述曰：釋所以。夫能破者，彼立有過，如實出之，顯示立、證敵，令知其失，能生彼智，此有悟他之能，可名能破。彼實無犯，妄起言非，以不能顯他宗之過。何不能顯？彼無過故，由此立名為似能破。

The Commentary states: Explaining the reason. As for a refuter: when the other's proof has faults, one points them out in accordance with reality, showing them to the proponent, the arbiter, and the opponent, causing them to recognize the error and giving rise to their understanding; possessing this capacity to enlighten others, it may be named a refutation. If the other has truly committed no fault, and one falsely raises words alleging error, one cannot reveal faults in the other's thesis. Why can one not reveal them? Because that [thesis] has no faults. Therefore, it is designated with the name 'apparent refutation'.
