Bāhyārthasiddhikārikā of Subhagupta
Masaaki Hattori
In his History of Indian Logic, S. C. Vidyabhusana gave the Sanskệt name for Dge-sruns, the author of the Sarvajña-siddhi-kārika and four other treatises preserved in the Tibetan Tripitaka, as Kalyānagupta ; while he identfied Subhagupta, who is called a follower of Dharmakirti (värttikānusärin) by Haribhadrasūri, with śubhākaragupta who flourished late in the 11th century. This theory, however, was criticised by B. Bhattacharya in the the foreword of G. O. S. edition of the Tattva-samgraha. He set forth the opinion that Haribhadrasūri must have referred to Bhadanta śubhagupta, whose views were mentioned several times in the Bahir-artha-parikșa of the Tattvasamgraha, and doubted whether śubhākaragupta, who was a Tāntrika, ever wrote any work on logic wherein he closely followed Dharmakirti. Y. Miyasaka has recently disclosed, in his article on Subhagupta's theory of the word, the view that Dge-sruns must be the Tibetan name for śubhagupta. His view is grounded on 1) that “dge' is considered as an equivalent for 'śubha', 2) that śubhagupta's theory of conventional designation' (sanketa) alluded to by Haribhadrasūri is similar to Dge-sruńs' theory expounded in his Śruti-parikșa-kārika and 3) that śubhākaragupta cannot be referred to by Haribhadrasūri, who, according to the recognized theory set up by H. Jacobi, is assigned to ca. 750 A. D. The writer of the present paper agrees with Y. Miyaşaka in regarding Dge-sruns and Subhagupta as being the same person, for this view can be verified by identifying quotations from Bhadanta śubhagupta in the Bahir-artha-parikșa of the Tattva-sangraha (-pañjika) with verses in the Bahyârtha-siddhi-kārika of Dge-sruns. The writer has prepared the following list of identification. (Skt.: Tattvasamgraha, Tib.:
