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.

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.

Gādādhari Volume-1

In these two volumes, Gadādhara Bhattācārya 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.

शब्दशक्तिप्रकाशिका (Śabdaśaktiprakāśikā (Vol-2))

In the second volume of Śabdaśaktiprakāśikā, Jagadīśa presents a detailed analysis of Prabhākara’s kāryānvitaśaktivāda and refutes this view. Jagadīśa defends the niravacchinna śaktivāda of the words like ākāśa etc. The view of Raghuntha Siromani with regard to the causal nexus of linguistic understanding has been refuted. Jagadisa offers an analysis of the nature of paribhāṣika śabda and argues that proper names given to individuals do not have śakti and they are to be treated as paribhāśaika śabda. Jagadīśa defends the view that śakti resides in all the three loci: the individual, the universal and the relation of samavāya that holds between an individual and the universal. Jagadīśa also refutes the Mīmāṃsaka view that the sentence has lakṣaṇā and the view of Ālaṃkārika regarding the vyāñjanā relation has been rejected. In this book, Jagadīśa offers a detailed analysis of different kinds of lakṣaṇā and in this context, one comes across a criticism of the Prabhākara thesis that the word having lakṣaṇā is not the cause of syntactic knowledge of the sentence. This book ends with an analysis of the nature of yogaruḍa śabda.

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.
