নবদ্বীপ মহিমা (Nabadwip Mahima)

This book is perhaps the first attempt to portray the detailed history of Navadvipa. The author starts the discourse with the history of the name ‘Navadvipa’ along with a description of the relation of Navadvipa to the rest of Bengal during the ancient period. The second part of the book contains a detailed description of the scholars of Navadvipa who worked on Navya-Nyāya, Smṛti, and Tantra. In the third chapter, one finds an elaborate presentation of Sri Chaitanya’s biography along with a discussion on Vaishnava religion. Since Navadvipa was ruled by the king of Krishnagar for a long time, there is a discussion on the rulers of Krishnagar, their contribution to the Navadvipa scholarship as patrons. The author also adds a discussion on the famous musicians, eminent persons trained in English education and business persons of Navadvipa.

शब्दशक्तिप्रकाशिका (Śabdaśaktiprakāśikā (Vol-1))

Śabdaśaktiprakāśikā is an important text written by Jagadīśa Tarkālaṃkāra containing an analysis of śabda pramāna following the Navya-Nyāya tradition. This work is a defence of many of the theses of Gaṅgeśa, the author of Tattvacintāmaṇi. In many places, the views of Bhatṛhari and Srīpatidatta, the author of Kalapa-pariśiṣta, have been critically assessed and defended. The author offers a detailed analysis of how the knowledge of the meaning of a sentence is generated through the presence of the elements like ākāṁṣkā, yogyatā and āsatti. Since the meaning of a word is defined in terms of śakti, a question arises with regard to the locus of śakti. Bhāṭṭa Mīmāṁsakas hold that śakti stays in the universal. Jagadīśa refutes this thesis of the Mīmāṁsakas. The author also refutes the thesis that the locus of śakti is the individual object, a view that is propagated by Raghunātha Śiromaṇi. Jagadīśa defends the view that combines both the insights that the locus of śakti is the individual object and the locus of śakti is the universal. In this book, Jagadīśa presents an analysis of the nature of lakṣanā. In this work we also find an analysis of how ākaṁkṣā, yogyatā and āsatti could be treated as the cause of understanding the meaning of a sentence. Jagadīśa, however, refutes the view that the knowledge of tātparya is the cause of understanding the meaning of a sentence, instead proposes the view that prakaraṇajñāna is the cause of understanding the meaning of a sentence. Thus in the present work the author, after defending śabdapramāṇa as an independent pramāṇa, offers his analysis of the ways of generating linguistic understanding.

जागदीशीव्याधिकरणम् (Jāgadīśvyādhikaraṇam)

This is a prakaraṇa text on the Nyāya theory of vyāpti written by Jagadīśa. The main theme of the work centres around the nature of vyāpti.Knowledge of vyāpti is the cause of inferential knowledge. If the definition of vyāpti is constructed in terms of avyābhicāritatva, then one could explain  avyābhicāritatva in five alternative ways. And none of these alternatives is acceptable, for this understanding of vyāpti would fail to account for kevalānvayi inference. In order to remove this problem, the definition of vyāpti is reconstructed as pratiyogivṛttidharmāvacchinna-pratiyogitākabhāvarupa vyādhikaraṇadharmāvacchinnabhāva. Jagadīśa examines this new definition of vyāpti and offers his justification, refuting all the possible objections.

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.

বাঙালির সারস্বত অবদান: বঙ্গে নব্যন্যায়চর্চা (Bangalir Saraswat Avadan: Bange Navyanyaya Charcha)

This is perhaps the most authentic history of Navya-Nyāya scholarship in Bengal with special emphasis on Navadvipa. In this book, the author presents a detailed description of the biographies and the works of the philosophers of Navadvipa. The author divides his work in the following chapters: 1. The Pre-Śiromaṇī age, 2.Raghunātha Śiromaṇī, 3. Bengali Commentators on Śiromaṇī, 4. The Post-Gadādhara Era, 5. Bengali Naiyāyikas in Kāśidhāma, 6. Nyaya Schools of Bengal. The author, with sufficient historical evidence, determines the time of many of the Navya-Nyāya scholars and he also proposes his views on the authorship of many of the Navya-Nyāya commentaries.

शब्दशक्तिप्रकाशिका (Śabdaśaktiprakāśikā (Vol-3))

The third volume of Śabdaśaktiprakāśikā contains an analysis of samāsa. The book starts with a presentation and analysis of the definition of samāsa in general. Jagadīśa distinguishes nitya samāsa from anitya samāsa. The present work contains an analysis of six kinds of samāsa, viz, 1. Dvigu, 2. Tatpuruṣa, 3. Avyaībhāva, 4. Bahubrīhi, 5. Dvandva. The author accepts another samāsa viz. Upapada. The Grammarians hold that the vigraha vākya and the samasta vākya do not have the same śakti and so the nature of understanding the meaning of the vigraha vākya does not amount to understanding the meaning of the samāsa. Jagadīśa refutes this view of the Grammarian and argues that both the vigraha vākya and the samāsa do possess the same meaning. While the traditional Pāṇinian grammar includes karmadhārāya samāsa in tatpuruṣa samāsa and dvigu samāsa in karmadhāraya samāsa, the Katantra Grammar includes dvigu samāsa in tatpuruṣa samāsa. Jagadīśa intervenes in this debate and holds that karmadhāraya and dvigu are independent samāsas and so he thinks that there are six kinds of samāsas viz. tatpuruṣa, avyaībhāva, bahubrīhi, dvandva, karmadhārāya and dvigu. In this book one finds a detailed analysis of all these six kinds of samāsa. Even if Jagadīśa does not accept upapada samāsa as an independent samāsa, still he offers an analysis of upapada samāsa on behalf of those who accept upapada samāsa.
