IV. The problem of Dinnāga's contributions to
Indian Logic. Closely connected with the above, but resting on a wider basis, is the question of the original contribations which Diināga is supposed to have made to Indian Logic:
(1) One such contribution, it is said, is the view that "the
proposition, the point of disputation or the thesis, is a judgment not the terms of a judgment. "* This view is expressed in the Pramāṇasanuccaya Ch II † and the passage in which it occurs has been quoted by Vācaspatimio'ra in the Nyagavārtikatātparya as Dinnāga's-which is now extracted as Fragment F | for easy reference. The substance of the verses bas been tbus summarised by Vācaspatimis'ra : "27 agaida धूमादग्निरूपधर्मान्तरानुमानमग्निदेशयोः संबन्धानुमानं च षयित्वाऽग्निविशिष्टदेशानुमानं समर्थि. at" The doctrine which is here attributed to Dindäga and is found in a work which is indisputably bis, does not appear for the first time in his logic, nor is it peculiar to him. That the problem had occupied the attention of earlier logicians is clear from Dinnāga's reference to different views prevailing on the subject. Moreover, the very tenet which is regarded as a contribution of Djänāga's to the logical theory is traceable to earlier writers. Vātsyāyana, the author of the Nyāyabbāsya while saying that fire was inferred from smoke ("727 atliaita”) in a passage where the precise form of the Probandum was not under discussion but only the different types of Inference, says in another place where the form of the Probandun required to be carefully stated for interpreting the Sutra:-" साध्यं च द्विविधम्-धर्मिविशिष्टो वा धर्मः शब्दस्यानित्यत्यं धर्मविशिष्टो वा yai analiz: quia IgE aga kail" Conformably to this Uadyotakara, the Vārtikakāra, says in the Vārtika on N.S.
I. i. 33" savaitgaliai hat hi 9789: ".
How is it then that in the passage quoted above, Uddyotakara and his commentator-Vācaspatimis'ra--criticise Dinnaga ? A careful study of
