Pramāṇavārttika (ཚད་མ་རྣམ་འགྲེལ་)
Commentary on Valid Cognition — dharmakirti’s magnum opus and the single most important text in the Buddhist logico-epistemological tradition. It became the primary text for Tibetan epistemological studies thanks to sakya-pandita’s influence.
Overview
Presented as a commentary on dignaga’s pramanasamuccaya, the Pramāṇavārttika in fact constitutes an independent and far more elaborate treatise. It consists of verse-form arguments (kārikā) across four chapters, each dealing with a major topic in epistemology and logic.
Structure
Chapter 1: Inference for Oneself (སྭཱརྟྷཱནུམཱན་)
The only chapter directly commenting on the Pramāṇasamuccaya. Deals with the nature and types of inference from the cogniser’s own perspective.
Chapter 2: Establishment of Valid Cognition (ཚད་མར་གྲུབ་པ་, pramāṇasiddhi)
The famous “Establishment of Buddha as Valid” — argues that there are consistent reasons for holding that reality conforms to Buddhist teachings. This provided a reference point for Buddhist thinkers asserting their viewpoints against Hindu criticism (dreyfus-recognizing-reality, p. 20). Dharmakīrti unpacks the epithets of Diṅnāga’s opening verse into a formal argument: compassion → practice → teaching → embodiment of epistemic instruments. “Compassion is the proof” of the Buddha’s reliability (westerhoff-dignaga-dharmakirti, p. 240).
Chapter 3: Perception (མངོན་སུམ་, pratyakṣa)
Covers the definition and types of perception, including the arguments establishing perception as a valid means of cognition. Contains the key verse on causal efficacy (PV 3:3): “Whatever has causal powers, that really exists in this context. Anything else is declared to be just conventionally existent” (westerhoff-dignaga-dharmakirti, p. 231). This is also the only chapter where Dharmakīrti consistently adopts his ultimate idealist (Yogācāra) perspective, discussing the identity of perceiver and perceived (westerhoff-dignaga-dharmakirti, p. 255).
Chapter 4: Inference for Others (པརཱརྟྷཱནུམཱན་)
Deals with the formal presentation of arguments for the purpose of convincing others.
Tibetan Reception
Before sakya-pandita’s promotion of this text, the Pramāṇaviniścaya (Ascertainment) had been the primary text for Tibetan epistemological studies. Sakya Paṇḍita’s decisive influence established the Pramāṇavārttika as predominant. He is said to have taught it daily and is the source of all its lineages in Tibet (dreyfus-recognizing-reality, p. 23).
Dreyfus uses “Commentary” as his abbreviation for this text throughout dreyfus-recognizing-reality.
The Sliding Scales
Westerhoff argues that the Pramāṇavārttika is best understood through the lens of Dharmakīrti’s “sliding scales of analysis” — four ascending levels of philosophical sophistication (ordinary → Abhidharma → particularism → idealism). Most of the text argues from the particularist (Sautrāntika) level, which Dharmakīrti knows to be provisional, to maximise shared assumptions with non-Buddhist interlocutors (westerhoff-dignaga-dharmakirti, pp. 253–256).
Mipham connects this strategy to shantarakshita’s Yogācāra-Madhyamaka synthesis: the difficulties of the aspect theory (sākāravāda) forced Dharmakīrti to shift from a Sautrāntika to a Yogācāra framework, mirroring the historical development from Bhāviveka to Śāntarakṣita (shantarakshita-madhyamakalankara-intro, pp. 26–27).
Pramāṇa and Madhyamaka
The logico-epistemological tradition was “primarily and intimately linked” with Svātantrika Madhyamaka from its inception (shantarakshita-madhyamakalankara-intro, p. 10). Candrakīrti rejected the tradition of Dignāga as antithetical to Madhyamaka insight, but his distrust was not shared by most Tibetans. Tsongkhapa’s paradoxical adoption of pramāṇa within a Prāsaṅgika framework — applying the logical method to a view that had traditionally rejected it — was “censured with great severity” by Sa-gya critics (shantarakshita-madhyamakalankara-intro, p. 16).
