  After offering his criticisms of Bhāvaviveka, Candrakīrti addresses the school of Buddhist logic and epistemology founded by Dignāga. The followers of this school did not present themselves as Mādhyamikas, so Candrakīrti does not accuse them of having failed to understand Nāgārjuna properly. He does, however, confront them with having failed to supply a convincing response to the radical critique Nāgārjuna had made of the very enterprise of grounding convictions on indisputable foundations. He recapitulates a passage of Nāgārjuna’s VV in which it is said that any proposition that is supposed to be warranted must rest upon a foundation of either direct experience or one of three kinds of reasoning. But the very claim that a proposition is warranted by a foundation is itself a proposition, and as such it must either require a warrant of its own or be deemed self-validating. If it requires a warrant of its own, the result will be an infinite regress of propositions needing warrants; if it is declared self-validating, then why not say of all propositions they are self-validating? Dignāga and his followers went ahead and talked about the grounding of propositions as if Nāgārjuna had never questioned the enterprise. Unless they provide a clear and convincing response to what Nāgārjuna said, there is no reason for anyone to take them seriously.
