Cha-ba Chökyi Sengge (ཕྱ་པ་ཆོས་ཀྱི་སེང་གེ་)
A pivotal figure in the formation of Tibetan epistemology. His innovations established the “new epistemology” (ཚད་མ་གསར་མ་) that was later inherited and refined by the Ge-luk tradition.
Contributions
- Wrote the first Summary (བསྡུས་པ་) of Dharmakīrti’s thought in Tibet — “played a crucial role in the founding of Tibetan scholasticism” (shantarakshita-madhyamakalankara-intro, p. 11)
- Initiated the Collected Topics (བསྡུས་གྲྭ་) literary genre, which became central to the Ge-luk curriculum
- Credited with settling the debate format practised by Tibetans — proposing debate through consequences (ཐལ་འགྱུར་, prasaṅga) rather than formal Indian logical arguments (dreyfus-recognizing-reality, p. 22)
- Proposed a realist interpretation of Dharmakīrti: epistemology should be established according to the Vaibhāṣika school and settled on the basis of “what is renowned to the world”
- Established numerous seminaries and developed many original academic methodologies, including the tradition of monastic debate still practised today (sonam-introduction-treasury)
- His works are no longer extant, but his influence pervades both Ge-luk and Sa-gya traditions (as a target of critique)
Specific Positions Critiqued by Sapan
- Proposed five types of non-valid cognition: correctly assuming consciousness (ཡིད་དཔྱོད་), inattentive cognition (སྣང་ལ་མ་ངེས་པ་), subsequent cognition (བཅད་ཤེས་), doubt (ཐེ་ཚོམ་), and distorted cognition (ལོག་ཤེས་). Sapan rejected the first three categories (sonam-introduction-treasury)
- Held that all valid cognitions necessarily eliminate superimpositions (ཚད་མ་ཡིན་ན་སྒྲོ་འདོགས་གཅོད་པས་ཁྱབ་) — i.e., valid cognition inherently determines its object. Sapan rejected this, arguing perception is passive (sonam-introduction-treasury)
- Held that the held object (གཟུང་ཡུལ་) applies to three types of mental episode (not just non-mistaken sense perception). Sapan regarded this as a misreading of the Indian sources (sonam-introduction-treasury)
- Held that object and subject coexist — a position denied by Dharmakīrti, who insists on their sequential nature. This was a more commonsense-friendly view (sonam-introduction-treasury)
- His solution on definition (the name of a definition should have a definition, while its meaning-distinguisher need not) was actually accepted by Sapan (sonam-introduction-treasury)
Svātantrika Allegiance
Cha-ba was a keen adherent of Svātantrika Madhyamaka and a formidable debater. He is said to have “brilliantly defended the Svatantrika view against Prasangika innovation and to have composed several refutations of Chandrakirti” (shantarakshita-madhyamakalankara-intro, p. 11). His intense interest in pramāṇa harmonised well with his Svātantrika leanings — the logico-epistemological tradition was “primarily and intimately linked” with Svātantrika Madhyamaka (shantarakshita-madhyamakalankara-intro, p. 10).
A “minority Buddhist interpretation” in India had already attenuated Dignāga and Dharmakīrti’s antirealism toward moderate realism; Cha-ba encountered and adopted this interpretation by “what may have been no more than a historical accident” (shantarakshita-madhyamakalankara-intro, p. 29). This interpretation was subsequently inherited by Tsongkhapa and moulded the general philosophical outlook of the Ge-luk school.
Legacy
sakya-pandita’s Treasure was primarily directed against Cha-ba’s realist innovations. sakya-chok-den complained that by the 15th century, the terminology of epistemological studies had become “hopelessly contaminated by the bizarre inventions of Cha-ba and his followers” (dreyfus-recognizing-reality, p. 26).
