 Secondly, observing again that if the epistemic instruments are self-established they will be established independently of the objects known, Nāgārjuna argues as follows. Assume that we wanted to chose those amongst all the different means of cognitive access to the world that deliver accurate knowledge of the nature of the objects known, that is, that qualify as epistemic instruments. We would select all those that have a specific internal quality. The possession of this quality would then guarantee that its possessor delivered accurate information about the nature of the objects cognized. But how is the connection between the specific internal quality and the correct representation of the object justified? After all there are all sorts of properties our means of cognitive access to the world can have, so how do we know that a specific one is a guide to accurate representation?
