The objective of this article is to explain vitally the literature, structure, terms, objective, nature, description and science of inference (technically called ‘anumana’) as found in the Nyaya shool of philosophy, and also to compare and contrast the different types of syllogistic inferences found in the Nyaya philosophy. Nyaya logic, ‘Nyaya Sutra’ and anvikshiki or tarkasastra (science of reasoning) are also discussed in this article. The classifications of inference into svartha and parartha; into purvavat, sesavat and samanyatodrsta; and into kevalanvayi, kevalavyatireki and anvayavyatireki are explained briefly. The concept of Vyapti is also explained. The components of a five-membered Nyaya Syllogism such as pratijna (proposition), hetu (reason), udaharana (example), upanaya (application) and nigamana (conclusion) are explained briefly. Finally, the caliber of the naturalistic Nyaya Syllogism is proved to be dated old enough with respect to the Aristotelian Syllogism.

Anumana, Pratijna, Hetu, Udaharana, Upanaya, Nigamana, Paksa, Sadhya, Linga, Vyapti, Kevalanvayi, Kevala-vyatireki and Anvaya-vyatireki.
