成唯識論演祕 2.283

2.283

有義：非《疏》釋云，因非如色等現量所得，非如心等比量所得，作此立因；因不定失，彼說無為非如色、心二量所得體相可得，應言許是有為非如色、心質礙、緣慮二量所得體相可得者，即無不定。

One interpretation holds: Rejecting the Commentary's explanation that states: The reason is that it is not apprehended by direct perception like form and so forth, nor is it apprehended by inference like mind and so forth—stating the reason in this way incurs the fallacy of an inconclusive reason (anaikāntika). For they [the opponents] say that unconditioned dharmas, unlike form and mind, are not apprehended by the two means of knowledge, yet their entities and characteristics are apprehensible. One should say: 'It being accepted that it is conditioned, it is not like form and mind, which possess material resistance and cognitive deliberation, having entities and characteristics apprehensible by the two means of knowledge'—then there is no inconclusiveness.
