There was a long and a time-honored tradition in ancient India where philosophers and thinkers met to discuss metaphysical issues over which there were multiple views. There are detailed narrations of such discussions, debates and dialogues recorded in Chandogya Upanishad, Brhadaranyaka Upanishad and Prashna Upanishad. The other early texts such as Aitareya Brahmana, Kathopanishad and others use terms like : tarka (reasoning), Vada (debate), Yukti (sustained arguments), Prameya (object of knowledge), Pramana (proof), Nirnaya (ascertainment) etc. which later became the principal terminologies of the Nyaya School. It is also said that the idioms of inquiry (Anveshiki) dealing with the theory of reasons (Hetu-vidya or Hetu-shastra) were mentioned in Manu samhita and Panini’s Ashtadhyayi.<ref name=":3" />

As Bimal Krishna Matilal observes in his work 'The Character of Logic in India':<blockquote>''.. The intellectual climate in India was bristling with questions such as: “Is there an atma different from sharira ?”; “Is the world (loka) eternal?”; ”What is the meaning, goal, or purpose of life?”; and, “Is renunciation preferable to enjoyment?” etc. which were of major concern.'' </blockquote>As teachers and thinkers argued about such matters, there arose a gradual awareness of the characteristics or patterns of correct, acceptable and sound reasoning. There were also concerns to evolve the norms to distinguish sound reasoning from pseudo-reasoning (hetvabhasa) which is unacceptable.<ref name=":0">Bimal Krishna Matilal, Jonardon Ganeri & Heeraman Tiwari (1998), The Character of Logic in India, SUNY Press, p. 31. </ref>

Gradually, the notions of ‘good’ and acceptable debate took shape as distinct from wrong and ugly arguments. That gave rise to the development of a branch of study dealing with theories of reasoning and logic (Hetu vidya or Hetu shastra). Subsequently, manuals came to be written for conduct of proper and successful debates (Tarka vidya or Vada vidya). These manuals included instructions and learning methods for the guidance of aspiring debaters. The earliest known text of that genre was Tantrayukti (structured argument) compiled to systemize debates conducted in learned councils (Parishad).

Debates and arguments then came to be recognized both as art of logical reasoning (Tarka vidya) and science of causes (Hetu shastra) following the path of a well-disciplined method of inquiry (anvikshiki) testing scriptural knowledge by further scrutiny. Therefore, scholars belonging to various schools of philosophy were imparted training in Tarka vidya: the art and skill of conducting impressive successful debates and disputations (Sambhasha or Vada vidhi) in learned assemblies (parishad).

Sambhasha is also called as Vada (discussion) in many texts. The concept of Vada is derived from the Nyaya darshana. It is said that,<blockquote>प्रमाणतर्कसाधनोपालम्भः सिद्धान्ताविरुद्धः पञ्चावयवोपपन्नः पक्षप्रतिपक्षपरिग्रहः वादः ।।१।।<ref>Nyaya Sutras, Adhyaya 1, [https://sa.wikisource.org/wiki/%E0%A4%A8%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%AF%E0%A4%B8%E0%A5%82%E0%A4%A4%E0%A5%8D%E0%A4%B0%E0%A4%BE%E0%A4%A3%E0%A4%BF/%E0%A4%85%E0%A4%A7%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%AF%E0%A4%83_%E0%A5%A7/%E0%A4%A6%E0%A5%8D%E0%A4%B5%E0%A4%BF%E0%A4%A4%E0%A5%80%E0%A4%AF%E0%A4%AD%E0%A4%BE%E0%A4%97%E0%A4%83 Part 2].</ref></blockquote><blockquote>''pramāṇatarkasādhanōpālambhaḥ siddhāntāviruddhaḥ pañcāvayavōpapannaḥ pakṣapratipakṣaparigrahaḥ vādaḥ ।।1।।''</blockquote>Amongst the 44 Vada marga padas (logical terms used in debate), the first one is Vada. It refers to a debate following the laws of shastra (text) ie. it should have 5 avayavas, paksha (in favour) and Pratipaksha (in opposing side) both laid down on the basis of Pramana (parametres of evidence) and tarka (logical reasoning).<ref name=":9" />

The science of inquiry, Atmavidya, was at a later stage called Anvikshiki. However, while comprising the entire function of Atmavidya, Anvikshiki, was in fact different from it. Kautilya recognized Anvikshiki as a distinct branch of study over and above the three, viz, Trayi (the Vedas), Vartta (Commerce) and Dandaniti (Polity).<ref name=":13">Satis Chandra Vidyabhusana (1921), [https://archive.org/details/in.ernet.dli.2015.489008/page/n1 A History of Indian Logic], Calcutta University.</ref><blockquote>आन्वीक्षिकी त्रयी वार्त्ता दण्ड-नीतिश्चैति विद्याः ।। ०१.२.०१ ।।<ref>Kautilya, Arthashastra, Adhikarana 1, [https://sa.wikisource.org/wiki/%E0%A4%85%E0%A4%B0%E0%A5%8D%E0%A4%A5%E0%A4%B6%E0%A4%BE%E0%A4%B8%E0%A5%8D%E0%A4%A4%E0%A5%8D%E0%A4%B0%E0%A4%AE%E0%A5%8D/%E0%A4%85%E0%A4%A7%E0%A4%BF%E0%A4%95%E0%A4%B0%E0%A4%A3%E0%A4%AE%E0%A5%8D_%E0%A5%A7/%E0%A4%85%E0%A4%A7%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%AF%E0%A4%83_%E0%A5%A8 Adhyaya 2].</ref> ''ānvīkṣikī trayī vārttā daṇḍa-nītiścaiti vidyāḥ ।। 01.2.01 ।।''</blockquote>The distinction between Atmavidya and Anvikshiki lay in this, that while the former embodied assertions about the nature of atman, the latter contained reasons supporting those assertions. Therefore, Anvikshiki dealt in fact with two subjects, viz. atman and hetu (theory of reasons). Later on, Anvikshiki was recognized as a distinct branch of learning that bifurcated into two branches - philosophy and logic.<ref name=":13" /> And this logic, developed in ancient India through the tradition of vada vidya, a discipline dealing with the categories of debate over various religious, philosophical, moral and doctrinal issues.<ref name=":0" /> Hence, Sambhasha is also called as Vada (discussion) in many texts.

Logic as the study of the form of correct arguments and inference patterns, developed in India from the methodology of philosophical debate. It developed in ancient India from the tradition of vada vidya, a discipline dealing with the categories of debate over various religious, philosophical, moral and doctrinal issues.<ref name=":0" />
