A Brief Account of the Jaina View of Inference

Summary

Gour Hazra's essay provides an accessible overview of the Jaina theory of inference and situates it within the broader Indian logical tradition. In Jain philosophy inference or anumana is one of the primary pramanas or valid means of knowledge alongside perception and testimony. Hazra explains that the Jaina conception of inference is broadly consonant with the Nyaya tradition but exhibits distinctive features. The Nyaya school distinguishes two types of inference: svartha anumana which is an inference carried out for one's own understanding and parartha anumana which communicates reasoning to another person. The svartha form consists of a two limbed syllogism comprising a premise called sadhya and a reason called sadhana. The parartha or public syllogism requires five limbs: pratijna (proposition) hetu (reason) udaharana (example) upanaya (application) and nigamana (conclusion). Hazra notes that Jain authors accept this structure but emphasise that each limb has pragmatic rather than purely formal significance. He reviews classic Jaina texts to show how they interpret inference in the context of anekantavada or the doctrine of manifoldness according to which reality has many aspects. Because entities possess innumerable characteristics an inference based on a single characteristic must be understood as conditional and limited. Hazra also outlines the Jaina classification of inference into dravya (substance) kshetra (space) kala (time) bhava (state) and svartha categories. The dravya type infers the existence of substances such as inferring fire from smoke on a hill; the kshetra type concerns location such as inferring water below the surface from the presence of lush plants; the kala type involves temporal inference such as predicting future fruit from the present seed; the bhava type concerns modes or qualities; and the svartha type relates to inner reasoning. This classification shows how inference operates across multiple domains. The author discusses the treatment of hetvabhasa or fallacies in Jaina logic and notes that Jains recognise several kinds of faulty inference similar to Nyaya but interpret them through the lens of non absolutism. Hazra emphasises that the Jaina theory of inference is inseparable from its ethical and metaphysical principles. Because Jains stress non violence and respect for multiple viewpoints they regard inference not as an absolute proof but as a tool for provisional understanding. Hazra suggests that the Jaina approach encourages intellectual humility by acknowledging that conclusions are always relative to particular standpoints. The essay thus highlights the originality of Jaina logic within the shared vocabulary of classical Indian epistemology.
