VigrahavyāvartanīとVaidalyaprakaraṇaの比較考察――pramāṇaとprameyaを中心に――

抄録

The Vigrahavyāvartanī, traditionally ascribed to Nāgārjuna, spends a large percentage of its length refuting the establishment of pramāṇa or “a valid means of cognition” and prameya or “the object of a valid means of cognition.” In this regard, while dealing with this topic in detail, the Vaidalyaprakaraṇa widely refutes the sixteen categories of discussion proposed by Naiyāyikas. Therefore, a comparative study of the Vigrahavyāvartanī and the Vaidalyaprakaraṇa with a focus on their discussion of pramāṇa and prameya remains an important task. Giving a detailed synopsis of the discussion of pramāṇa and prameya in these two texts, this article tries to clarify the similarities and differences between them.
