2.678

述曰：下第三、文總申假說不依真事，謂此假智及詮必定依聲而起，如聞某甲即便緣之，或起言說，故必依聲，如作色解，及說色言，由聞他聲說之為色，方能了故。詮謂名等，有詮辨故。聲謂表業，雖不相離各據一勝。若爾，嬰兒等應無比智及生無色，比智應無，不聞他聲起假智故。此理不然，如鼠聞猫聲及或見鵄等即便急走，豈彼生已能起證智耶？此鼠前生曾為猫、鵄之所食噉，今既見已有比智生，定知如前還被彼殺，即便急走。生無色亦爾，無始及下界曾熏習故，曾聞說有無色界定修生彼故。不爾，此中唯說下界智依聲起，除無色界起，故知諸智皆緣共，生假智及詮，詮謂名等，必依聲起。

The Commentary states: Below, the third section generally presents how nominal designation does not rely upon real entities. That is, this nominal intellect and expression necessarily arise in reliance on sound. Just as upon hearing [the name of] a certain person one immediately conditions him or gives rise to speech, so it necessarily relies on sound; just as forming the conceptualization of matter and speaking the word 'matter' can only be understood because of hearing another's sound saying 'matter'. 'Expression' refers to names and the like, because they have the function of expressing and discerning. 'Sound' refers to communicative action; although they are not separate from each other, each is based on a distinct preeminence. [Objection:] If that is so, infants and the like would lack inferential intellect, and those born into the formless realm would also lack inferential intellect, because they do not hear others' sounds to give rise to nominal intellect. This reasoning is incorrect. Just as when a mouse hears the sound of a cat or sees a hawk and the like, it immediately flees in haste—could it be that having been born, it is able to give rise to direct realization? This mouse was eaten by cats or hawks in a previous life; now, having seen [them], an inferential intellect arises, and knowing with certainty that as before it would be killed by them, it immediately runs away. Being born into the formless realm is also like this: because of beginningless habituation and habituation in the lower realms, having previously heard that there is formless-realm concentration, one cultivated it and was born there. If it were not so, here it is only stated that the intellect of the lower realms arises in reliance on sound, excluding the arisings in the formless realm; hence we know that all intellects condition the universal. Nominal intellect and expression arise—expression referring to names and the like—necessarily in reliance on sound.
