Book Title: Jain Nyayano Vikas (The Development of Jain Logic) Author: Munishri Dhurandharvijay Publisher: Unknown Catalog Link: https://jainqq.org/explore/034522/1
This work, by Munishri Dhurandharvijay, traces the significant development of Jain logic and philosophical argumentation from 1000 to 1700 Vir Nirvana Samvat. It highlights key figures and their contributions in establishing and refining Jain reasoning within the broader Indian philosophical landscape.
Early Period: The Dominance of Faith and the Need for Logic
The text begins by describing a past era where Shraddhavad (faith-based reasoning) was highly prevalent. People were told that the words of a Muni (ascetic) were beyond logic and questioning. Scriptures, like the Vedas and the dharma prescribed by Manu, were considered divinely ordained and unquestionable. This blind faith led to a situation where critical thinking was discouraged, and those who employed logic (Tarkvad) found it difficult to survive, often being ostracized by the faithful.
This era of unquestioning faith, while not inherently bad, was exploited by self-interest, leading to practices like violent rituals (Yagya) and animal sacrifices, even human sacrifices (Naramegh Yagya), resulting in rivers of blood and skin. The text emphasizes the dire need for logic to address these societal ills.
Lord Mahavir and the Dawn of Logic (Yukti-vad)
The emergence of Lord Mahavir is presented as a pivotal moment. He is credited with ushering in an era of Yukti-vad (logic-based reasoning), encouraging proponents of logic, and acting as a pioneer for rational thought. Even followers of the Vedas, like Indrabhuti and others, who had doubts about the soul, heaven, merit, demerit, and the afterlife due to the lack of logic in Vedic pronouncements, found clarity and stability in Mahavir's teachings, which were firmly rooted in reason. Mahavir's teachings were deliberately made logic-सिद्ध (logic-proven). He encouraged questioning, with Gautam Swami famously asking "Why, O Bhagavan?" This approach validated the rational inquiry into spiritual truths.
Mahavir himself stated that a path of logic combined with scriptural guidance (Nyayukt Aagam) is beneficial. He likened these two aspects to the wheels of a chariot, essential for its movement. However, he also cautioned that some, despite hearing the logical path (Nyayayukt Marg), remained bound by faith, highlighting the persistent influence of traditional belief. This led to the insightful critique that if something is flawless (like pure gold), why should it fear examination? Just as a goldsmith tests gold with various methods, ascetics were encouraged to test Mahavir's words through examination, not just through reverence.
The Establishment of Jain Logic (Nyaya)
Following Mahavir, his disciples and later scholars organized his teachings into scriptures, systematically incorporating the principles of logic.
- Umaswati: Considered the first great proponent of the Nyaya style in Jain philosophy, Umaswati, in his Tattvartha Sutra, stated that true knowledge arises from Pramana (valid means of knowledge) and Nyaya (logic).
- Siddhasen Diwakar: A prominent figure in Jain logic, Siddhasen Diwakar authored significant works like Sanmatitarka and Nyayavatara. He is praised for his adherence to logic and his role in establishing Jain epistemology. He encouraged the study of the teachings of Buddhist logicians like Dinaga.
- Mallavadi: Another important logician, Mallavadi authored Naya Chakravala and successfully debated with Buddhists, upholding the banner of Jainism.
The Golden Age of Jain Logic (Vir Nirvan Samvat 1000-1700)
The period from 1000 to 1700 Vir Nirvana Samvat is described as the "midday" of Jain logic. During this time, various schools of thought like Buddhism and Vedanta posed challenges, attempting to obscure the brilliance of Jain logic. This era saw the rise of numerous scholars who defended and illuminated Jain reasoning.
Key Scholars and Their Contributions:
The text then introduces several influential Jain logicians from this period:
- Haribhadra Suri: Active around the 6th century Vikram era, he was a Brahman by birth who converted to Jainism. He was a master of 14 Vidya (disciplines) and a formidable debater who defeated Buddhists. He authored many Jain logic texts, including Anekaantavaada Pravesh, Anekaantajayapataka, and Darshana Samuchchaya. His writings are characterized by their clarity and ability to deeply penetrate the reader's understanding. His works engage with and refute the arguments of other philosophical schools.
