Over 2,500 years, philosophers in India refined a truth-centered and rhetorically egalitarian method of analogical debate: Nyāya vāda, and its five-part expression, the “Nyāya method.” According to Indian tradition, its practices emerged in the context of inter-scholar debates. However, most historical examples of Indian debate occur in mythical/religious dialogues between teacher and student, and currently Nyāya's scholars focus on theory, neglecting social practice. While Indologists describe the “what” of Nyāya, their bias toward theory leaves its conversational uses unexplored. Comparative rhetoricians describe Indian rhetoric with Greek terminologies as points of reference, and miss Nyāya's theoretical and practical debate tradition. This essay addresses this lack of social context and paucity of representation of Nyāya. It shows how informal debates in ancient literary/historical dialogues presage Nyāya's formulation and traces Nyāya's use in contemporary public examples, illustrating its rhetorical journey from discussions of scholars and kings, to academic formulization, to popular dialogic expression. Nyāya offers a clear alternative to Western confrontational rhetoric, and the presence of Indian “rhetorical” practice and theory undermines assumptions about “rhetoric” being uniquely Greek in origin, underscoring the need for comparative rhetorics.

As Aristotle began to codify rhetorical practices in Greece, a theoretical and pragmatic text on argument, the Nyaya Sutra, emerged in Ancient India, founding one of six key philosophies of India. Though it describes in detail a procedure of reasoning based on a five-part method of dialogic presentation, the rhetorical emphases of the Nyaya approach have been mostly overlooked. This essay proposes Nyaya's inclusion in the field of rhetorical studies, exploring its methods within their historical context, comparing its approach to the traditional logical syllogism, and relating it to the contemporary perspectives of Stephen Toulmin, Kenneth Burke, and Chaïm Perelman.
