Two of the terms in the title are from Vidyānandin’s Tattvārtha-śloka-vārttika, which is his commentary on Umāsvāti’s Tattvārtha-sūtra. Sūtra 6 of the TAS states the following: pramāṇa-nayair adhigamaḥ, ‘knowledge—of the seven categories—is obtained through the pramāṇas and the nayas’). Vidyānandin’s commentary on this sūtra 6 entails a total of 56 ślokas, with his own prose vārttika on each of them in varying lengths. TAŚV 1, 6, 1–8 deal with particulars and universals, for which he uses the synonymous pairs aṃśa/aṃśin and (...) avayava/avayavin. That he is attacking the Buddhist position regarding this age old theme in Indian philosophy, is evident also in that he quotes Dharmakīrti’s Pramāṇa-vārttika. By the time he comes to his TAŚV 1, 6, 6, he establishes that an object as a whole is open to perception and that the Buddhist also accepts perception as a valid means of knowledge, but does not accept the perception of an object as a whole. From TAŚV 1, 6, 11 onwards Vidyānandin continues with the same theme, elaborating his attack of the Buddhist view even further, doing so in terms of svasaṃvedana, pratyakṣa and pramāṇa. The presentation will attempt to deal with these concepts in order to see how Vidyānandin vindicates the Jaina position vis-à-vis the Buddhist one. This presentation will continue from my previous study of Vidyānandin’s TAŚV 1, 6, 1–10. (shrink)

Two eight-century Jaina contemporaries, a Śvetāmbara philosopher Siddhasena Mahāmati and a Digambara Akalaṅka Bhaṭṭa revolutionised Jaina epistemology, by radically transforming basic epistemological concepts, which had been based on canonical tradition. The paper presents a brief historical outline of the developments of basic epistemological concepts in Jaina philolosophy such as the cognitive criterion and logical faculties as well as their fourteen typological models which serve as the backdrop of important innovations in epistemology introduced by Siddhasena, Pātrasvāmin and Akalaṅka. An important contribution (...) of these Jaina thinkers was to economize Indian logic and the rules of inference, first, by devising only one kind of logical reason called ‘inexplicability otherwise’, based on the single inseparable connection of the proving property with the inferable property, and, second, by limiting the necessary number of the members of the proof formula merely to two. These two innovations were related to the thinkers’ intention to devise a logic which would not primarily be based on empirical verification but its structural patterns would be valid irrespective of external observation. Further, the paper focuses on the nature of the epistemological shifts which Siddhasena and Akalaṅka introduced independently of each other and on the question how Siddhasena’s and Akalaṅka’s ideas were partly anchored in Buddhist concepts of the pramāṇa school of Diṅnāga and Dharmakīrti. With the Buddhist background, Siddhasena sought to define the criteria essential to distinguish true from false cognitions and to provide a novel classification of the pramāṇas. He can further be accredited with formulating the first Jaina descriptive definition of the cognitive criterion. The final section of the paper explains how Akalaṅka applies novel epistemological ideas, first, to construct realistic ontology and objectivity of both the external world and the cognising subject, and, secondly, to combat fundamental Buddhist concepts such as idealism and momentariness.
