Similarly, when conventional usage is to be proved in the case of non-apprehension, the application is: Where things that are accepted as meeting the conditions of perceptibility are not perceived, those [places] are fit for conventional usage regarding their absence - for example, rabbit's head etc. are fit for conventional usage regarding the absence of horns; and [there is] non-apprehension of universals and other categories accepted by others (which are considered to meet the conditions of perceptibility) in spotted cows etc. which are accepted as their substrates - this is non-apprehension based on essential nature.
