Gādādhari Volume-2

In these two volumes, Gadādhara Bhhattācārya offers a detailed analysis of the views found in Tattvacintāmaṇi of Gaṅgeśa and in Dīdhiti of Raghunātha Śiromaṇi. Almost all the major conclusions of Navya-Nyāya have been explained with great defence.

प्रामाण्यवाद: (Prāmāṇyavādaḥ)

In this book, Harirama Tarkavagisa critically assesses the Mīmāṃśa theory of self-luminosity of knowledge. According to Prabhākara, the knower, the object of knowledge and the knowledge itself are apprehended in one go. The Bhaṭṭa Mīmāṃsakas hold that knowledge is inferred through a property called knownness. Murāri Miśra, another Mīmāṃsaka philosopher, holds that knowledge is known in a subsequent knowledge called introspection. Harirāma, following the footsteps of Gaṅgeśa, argues that since sometimes doubt regarding the validity of knowledge arises in the third moment after the origin of knowledge, the validity of the knowledge is apprehended by something other than the totality of the causal conditions of that knowledge. Harirama further argues that there is something wrong with the thesis that knowledge is self-luminious.

प्रामाण्यवाद: (Prāmāṇyavādaḥ)

The original  text of Gaṅgeśa, called Tattvacintāmaṇi, has been commented on by  both Raghunātha Śiromaṇi and Gadāhara Bhattācārya. If knowledge is gained through the ways of knowing, then the very nature of knowledge rests on the nature and veridicality of these recognised ways of knowing. An examination of the veridicality of the ways of knowing is known as pārāmānya. In this book, both Raghunātha and Jagadīśa offer a detailed analysis of the debate concerning the nature and veridicality of the very idea of pramāṇa.

ध्ब्मसजन्यभावयो: कार्यकारणभावरहस्यम् (Dhvaṃsa- Janyabhāvayoḥ Kārya-Kāraṇabhāvarahasyam)

In this essay, Harirama Tarkavagisa undertakes an analysis of the nature of the causal relationship between a positive effect and destruction. The author examines the nature of the inference viz. Dhvaṃsa is due to vināśa. If one takes into consideration this inference, there must be a hetu here and the hetu could be said to have an upadhi viz. Bhāvatva. Harirama, in this context, presents different ways of formulating the causal relation. The author ends this essay by concluding that the positive effect (janyabhāva) could be said to be the cause of destruction (dhvaṃsa) through the relation of pratiyogitva.
