Historical Development of Jaina Epistemology and Logic
By Anupam Jash
Summary
Dr Anupam Jash traces the evolution of Jain epistemology and logic from antiquity to the modern era. He divides the development into three broad periods. The āgamic period begins with Tīrthaṅkara Mahāvīra (around 600 BC) and extends to the first century AD; during this time, the foundations of Jain epistemology were laid in the canonical texts and the discourses of Mahāvīra’s disciples. The philosophical period spans the first or second century through the eighth century AD and includes thinkers such as Kundakunda, Umāsvāti, Siddhasena Divākara and Samantabhadra, whose works systematised the doctrines of pramāṇa (means of valid knowledge), nayavāda (partial standpoints), syādvāda (doctrine of conditional predication) and anekāntavāda (principle of non‑one‑sidedness). The third, tārkik period begins in the 18th century with Yaśovijaya, who integrated Navya‑Nyāya logical techniques into Jain scholarship and responded to contemporary debates with other Indian schools. The article highlights the dawn of Jain epistemology by tracing the concept of knowledge (jñāna) to the time of Pārśvanātha and Mahāvīra and recounts how the first gaṇadhara, Indrabhūti Gautama, organised Mahāvīra’s discourses into sūtras. Dr Jash outlines the five kinds of knowledge recognised in Jainism—sensory (mati‑jñāna), scriptural (śruta‑jñāna), clairvoyance (avadhi‑jñāna), telepathic (manaḥparyāya‑jñāna) and omniscience (keval‑jñāna)—and discusses the classification of pramāṇas into direct and indirect forms. The article also describes the contributions of later logicians such as Akalaṅka, Vidyānanda, Prabhācandra and Hemacandra, who refined logical techniques and defended Jain doctrines against Buddhist and Nyāya critiques. Throughout, Dr Jash emphasises that Jain epistemology is distinguished by its pluralistic approach: truth is many‑faceted, and any statement expresses only a partial standpoint. This epistemic humility fosters tolerance and dialogue among differing perspectives, making Jain logic relevant for contemporary pluralistic societies.
Conclusion
The survey concludes that Jain epistemology and logic evolved through sustained engagement with other Indian philosophies. By insisting that knowledge is relative to the standpoint of the knower and by developing sophisticated theories of inference and conditional predication, Jain thinkers offered a model of intellectual humility and tolerance. Dr Jash suggests that this tradition remains valuable today for encouraging open‑mindedness and respectful debate.
