Nyaya Sutra (न्यायसूत्राणि) by Gautama is the first work on Nyaya Darsana and is composed of five adhyayas and each adhyaya is divided into two Ahnikas (आह्निकः). It contains references to the Samkhya, Yoga, Vaiseshika, Mimamsa, Vedanta and Buddhist systems of philosophy. It is clear from the early commentaries on the Nyaya-sutras that the author of the sutras was distinctly named as Akshapada. Both the Bhashyakara, Vatsyayana and Vartikakara, Udyotakara, affirm that Akshapada gave the Nyaya philosophy in a systematic way. Padmapurana, Skanda purana etc., mention that Nyaya shastra was expounded by Gotama or Gautama. |

| + | The dialogues and discourses which were the characteristic features of the Upanisadic period naturally resulted, in course of time, in the formulation of definite methods of debating and forms of reasoning; and these gave rise to a science, which was originally called [[Anvikshiki (आन्वीक्षिकी)|Anvikshiki]], the science of inquiry , then Tarkavidya, the science of debating; or Hetu-vidya, the science of reasoning; and ultimately, Nyaya-shastra, the science of logic.<ref name=":2" /> Thus Nyaya is chiefly concerned with the means to attain true knowledge of reality (metaphysics) and theories of knowledge. |
