 Second, even though the main purpose of refutation-arguments is to show that the plurality of things in the world shouldn’t be treated as ultimately real, Śrīharṣa claims that they may also prove useful for the opponents of non-dualism. For instance, if one is a Nyāya-Vaiśeṣika philosopher who admits the reality of methods of knowing, etc., then one may use at least some of the refutation-arguments to rule out alternative views held by other philosophers, including the views of their predecessors within the same school as well as their opponents. Moreover, even in the kind of debate where one is engaged in the pursuit of truth and doesn’t merely seek to defeat one’s opponent, one would have to respond to refutation-arguments before one could arrive at one’s own view. Thus, refutation-arguments have universal application (KKh 123–125).
