The Nyāya-sūtra, which is supposed to be the earliest work extant on Nyāya philosophy, treats of four distinct subjects, viz., (1) the art of debate (tarka), (2) the means of valid knowledge (pramāṇa), (3) the doctrine of syllogism (avayava), and (4) the examination of contemporaneous philosophical doctrines (anya-mata-parīkṣā). The first subject, ample references to which are met with in the old Brahmanic, Buddhistic, and Jaina works, seems to have been first handled by a sage named Gotama or Gautama, who is reputed to have flourished in Mithilā (North Behar) about 550 b.c. The second subject, which is also referred to in old books, was associated with the art of debate at a very early stage. These two subjects, combined together, constitute the Tarka - śāstra (the philosophy of reasoning), popularly known as Gautamī vidyā (the Gotamide learning).
469 note 1 For Gotama or Gautama as the founder of Tarka-śāstra, see Naiṣadhacarita, bk. xvii, verse 75; Padma-purāṇa, Uttara-khaṇḍa, ch. 263; and Skanda-purāṇa, Kālikā-khanḍa, ch. xvii.
469 note 2 Some philosophical doctrines of the third and fourth centuries a.d. were incorporated into the Nyāya-sūtra of Akṣapāda by Vātsyāyana, the first commentator (about 400 a.d.), through the introduction of certain sūtras of his own making fathered upon Akṣapāda.

471 note 2 Seeing that the Greek word “Syllogismos” and the Sanskrit word “Saṁkhyā” or “Sāṁkhya” are identical in signification, one may say that Aristotle derived his doctrine of the Syllogism from the Sāṁkhya Philosophy of Kapila. But the Sāṁkhya Philosophy is not known to have dealt with the doctrine of the Syllogism at all.

Sylvain Lévi maintains on the authority of Chinese books that Caraka, the author of the Carakasaṁhitā, lived at the Court of Kaniṣka [in Jālandhara, Punjab]. I provisionally take the date of Kaniṣka to be 78 a.d.

483 note 1 Dharmakīrti and his followers, who say that non-existence is inferred and not perceived, assume non-perception as a middle term (sign). But the majority of Indian logicians maintain that non-existence of a thing is perceived by the same sense by which the thing itself is perceived. Hence non-perception is not acknowledged by them as a middle term (sign).

In the examples given to illustrate the description of the Enthymeme that which belongs to the first figure has its three terms and two propositions specified, like a complete and regular syllogism.”

485 note 5 DrGrote, George, in his Aristotle, vol. i, Analytica Priora, i, ch. v, p. 206Google Scholar, says that Aristotle includes in a syllogism the two premises as well as the conclusion. But on the same page he quotes in a footnote the opinion of Julius Pacius (ad. Analyt. Prior i), who said that the syllogism consisted of the two premises alone, and the conclusion was not a part thereof, but something distinct and superadded.
