Dharmakīrti argues that there is no pramāṇa (valid means of cognition or source of knowledge) for a thesis that is a self-contradiction (svavacanavirodha). That is, self-contradictions such as ‘everything said is false’ and ‘my mother is barren’ cannot be known to be true or false. The contemporary scholar Tillemans challenges Dharmakīrti by arguing that we can know that self-contradictions are false by means of a formal logical inference. The aims of the paper are to answer Tillemans’ challenge from what we take to be Dharmakīrti’s or Dharmakīrtian (someone who is like Dharmakīrti) perspective and to demonstrate the unique features of Dharmakīrti’s view of inference. By so doing, we show that the epistemology in relation to the formal conception of logic that underlies Tillemans’ challenge is problematic from Dharmakīrti’s or Dharmakīrtian perspective. The paper, thus, presents Dharmakīrti’s view of inference and logical reasoning as well as a Dharmakīrtian challenge to the formal conception of logic that is the dominant contemporary conception.

The liar paradox is still an open philosophical problem. Most contemporary answers to the paradox target the logical principles underlying the reasoning from the liar sentence to the paradoxical conclusion that the liar sentence is both true and false. In contrast to these answers, Buddhist epistemology offers resources to devise a distinctively epistemological approach to the liar paradox. In this paper, I mobilise these resources and argue that the liar sentence is what Buddhist epistemologists call a contradiction with one’s own words. I situate my argument in the works of Dignāga and Dharmakīrti and show how Buddhist epistemology answers the paradox.

Nāgārjuna’s Middle Way (Madhyamaka) doctrine met with the objection that it is a mere verbal attack (vitaṇḍā) against other philosophical positions. As one of the Madhyamaka critics pointed out: because Nāgārjuna does not hold own position, he is not able to justify his criticism of the essence (svabhāva). The article is an answer to the question whether, in the context of Indian philosophy, it is possible to know things devoid of essences. Theory of knowledge of this kind, i.e. the concept of omniscience (sarvajña) was presented in Aṣṭasāhasrikāprajñāpāramitā sutra. Associations between Nāgārjuna’s texts and the sutra suggest that omniscience could be a substrate for epistemological position of the Middle Way.

The aim of this paper is to present two arguments against the dialectical interpretation of Nagarjuna's philosophy. This interpretation understands Nagarjuna's philosophy as a method of deconstruction, abstracting from Nagarjuna's own standpoint. The first argument refers to the metaphysical presuppositions of this method. The second argument refers to the positive statements asserted by Nagarjuna and focuses mainly on those concerning Buddhist practice. Furthermore, the conception of 'skilful means' and 'the two truths' will be discussed. The conclusion of this paper is that Nagarjuna's philosophy is based upon determining the conditions of the possibility of the Buddhist practice rather than on a dialectic without any metaphysical assumptions
