Chronological Development of Jaina Logic

Summary

Jaina logic, which seeks to systematise reasoning in accordance with the principles of anekāntavāda and syādvāda, evolved over centuries. Early canonical texts contain dialogues illustrating non‑absolutism, but the first pure logic treatise is Siddhasena Divakara’s Nyāyāvatāra (c. 5th–6th century CE), which introduces basic principles of inference. His later work Sanmatitarka (The Logic of the True Doctrine) is considered the first major Jain logic text written in Sanskrithttps://en.wikipedia.org/wiki/Jain_literature#:~:text=According%20to%20Winternitz%2C%20after%20the,45. It expounds a seven‑valued logic that allows propositions to be affirmed, negated or expressed in multiple ways, reflecting the Jain belief that truth is multifaceted. In the 8th century, Mallavadin composed Nayacakra and Dvadasaranayacakra, encyclopaedic works that compare various schools of Indian philosophyhttps://en.wikipedia.org/wiki/Jain_literature#:~:text=,46. Akalanka (720–780 CE) systematised Jaina logic through works like Nyāya‑viniścaya and Pramāṇa‑saṃgraha, defending Jain epistemology against Buddhist and Nyāya critiques. Prabhācandra and Abhayadeva continued this line by producing extensive commentaries and treatises on logic and epistemologyhttps://en.wikipedia.org/wiki/Jain_literature#:~:text=,46. The tradition remained vibrant in the medieval period, with scholars like Vadideva and Hemachandra (11th–12th centuries) elaborating on syādvāda and the concept of conditional predicationhttps://en.wikipedia.org/wiki/Jain_literature#:~:text=,the%20supremacy%20of%20doctrine%20of. In the 17th century Yaśovijaya, a scholar steeped in Navya‑Nyāya (New Logic), wrote over a hundred works and produced commentaries on earlier Jain logical textshttps://en.wikipedia.org/wiki/Jain_literature#:~:text=,essence%20of. His adoption of Navya‑Nyāya terminology brought Jain logic into dialogue with contemporary philosophical trends. The article emphasises how each phase built on previous work, refining the methods of inference, the theory of viewpoints (naya) and the doctrine of conditionality. Jaina logic aimed not only at philosophical analysis but also at cultivating open‑mindedness, recognising that any statement is true only under certain conditions. By tracing the chronology from Siddhasena to Yaśovijaya, the article demonstrates Jainism’s sustained engagement with logical theory.
