Nyaya

The Story

Nyaya means 'that by which the mind is led' — logic. Founded by Sage Akshapada Gautama (not the Buddha), it is Bhārat's school of epistemology and reasoning, devoted to the question: how can we know what is true? The answer mattered, because everything else — ethics, liberation, science — depended on getting knowledge right.

Nyaya identified four pramanas, or valid means of knowledge: Pratyaksha (perception), Anumana (inference), Upamana (comparison), and Shabda (trustworthy testimony). Its most famous tool is the five-member syllogism — a formal proof with premise, reason, example, application, and conclusion. Scholars used it for centuries to win debates across the subcontinent.

The Nyaya method is unmistakably scientific: define terms precisely, demand evidence, expose fallacies. Its analysis of fallacies (hetvabhasa) — defective reasons that look valid — reads like an ancient textbook on critical thinking. The great debate halls of Mithila and Kashmir were, in effect, Bhārat's first universities of logic.

Navya-Nyaya, the 'new logic' developed in 13th-century Mithila, refined these tools into a razor-sharp technical language so precise that modern scholars compare it to formal mathematical logic. logicians were exploring of Bhārat quantified logic centuries before it appeared in the West.
