Pramāṇasamuccaya (ཚད་མ་ཀུན་བཏུས་)
Compendium of Valid Cognition — the foundational treatise of the Buddhist logico-epistemological tradition, by dignaga.
Overview
This text established the systematic framework for Buddhist epistemology that dharmakirti would later elaborate and defend. It covers the entire range of Buddhist logic and epistemology in six chapters.
Opening Verse
The famous verse of homage addresses the Buddha as pramāṇabhūta (“embodying the epistemic instruments”) — not authoritative by enlightened status but because his enlightenment flows from the correct application of epistemic instruments (westerhoff-dignaga-dharmakirti, p. 221):
Having bowed down to Him, who embodies the epistemic instruments, who seeks the benefit of the world, the teacher, the well-gone, the protector, I here make a single compendium of my various scattered [writings], to establish epistemic instruments.
dharmakirti later unpacked these epithets into a formal argument for the Buddha’s reliability in Ch.2 of the pramanavartika (westerhoff-dignaga-dharmakirti, p. 240).
Integration of Two Traditions
As Katsura explains, the Pramāṇasamuccaya represents the first systematic integration of two previously separate traditions of Indian logic (katsura-dignaga-lectures):
- The debate tradition (vāda) — from Brahmanical brahmodya debates to the Points of Defeat (nigrahasthāna) of the Carakasaṃhitā and Nyāyasūtra, and Buddhist vāda manuals by Nāgārjuna and Vasubandhu
- The epistemology tradition (pramāṇa) — from the Carakasaṃhitā’s five pramāṇas through the various orthodox schools
Chapters I, II, and V belong to the pramāṇa tradition; Chapters III, IV, and VI to the vāda tradition. Dignāga integrated them through the terms svārthānumāna (inference for oneself) and parārthānumāna (inference for others), showing via the trairūpya theory that inference and proof are essentially the same — the former a mental process, the latter its linguistic expression (katsura-dignaga-lectures).
Chapter IV (Example) should properly be included in Chapter III (Proof), since Dignāga’s proof consists of three propositions — Thesis (pakṣa), Reason (hetu), and Example (dṛṣṭānta) — and Chapter III only deals with the first two (katsura-dignaga-lectures).
Chapter VI examines Fallacious Objections (jāti), rejecting reductio ad absurdum (prasaṅga) as proof while admitting it as a means of refutation. Points of Defeat receive no special treatment from Dignāga; it is dharmakirti who treats them fully in his Vādanyāya (katsura-dignaga-lectures).
Key Innovations
- Established that there are exactly two valid means of cognition: perception and inference
- Originated the apoha (exclusion) theory of meaning
- Drew the fundamental distinction between specifically-characterised (object of perception) and generally-characterised (object of thought)
- Formulated the triple mark (trairūpya) of valid inference (westerhoff-dignaga-dharmakirti, p. 227)
- Distinguished inference for oneself (mental model) from inference for others (linguistic expression) (westerhoff-dignaga-dharmakirti, pp. 228–229)
- Rejected pramāṇasamplava (mixing of epistemic instruments): each epistemic instrument accesses only one kind of object (westerhoff-dignaga-dharmakirti, p. 234)
- Established self-awareness (svasaṃvedana) as both the result of cognition and the essential operation of all cognition (katsura-dignaga-lectures)
Tibetan Reception
Tibetan thinkers primarily understood Dignāga’s ideas through dharmakirti’s interpretations. The Pramāṇasamuccaya was translated into Tibetan but received less direct commentarial attention than the pramanavartika (dreyfus-recognizing-reality, p. 1).
