俱舍論疏 4.203

4.203

論「如是非理至是為非理」，經部責無如色、聲等，為其眼、耳現量可知。如貪、瞋等他心智知，如眼、耳等比量可知，以有見、聞用故，故知別有體性。其得既無現量可知，復無用故比量可知，故無體也。既無二量，可知是為非理。

[On the passage in] the treatise, from "It is unreasonable in this way" to "this is why it is unreasonable": The Sautrāntika reproaches that it is not directly perceptible (pratyakṣa) by the eye or ear like visible matter and sound; nor is it known by the knowledge of another's mind like greed and anger; nor is it knowable by inference (anumāna) like the eye and ear, which are known to have distinct real entities because they have the functions of seeing and hearing. Since this acquisition is neither knowable by direct perception, nor knowable by inference because it lacks any function, it has no real entity. Since it lacks both means of valid cognition (pramāṇa), being knowable in this way is unreasonable.
