As Bimal Krishna Matilal observes in The Character of Logic in India:

As Bimal Krishna Matilal observes in The Character of Logic in India:

.. The intellectual climate in India was bristling with questions such as: “Is there a soul different from body?”; “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. 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. Gradually, the notions of ‘good’ and acceptable debates 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 Tantra-yukti (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).

Nyaya, one among the 6 darshanas deals with well-organized logical ways of ascertaining the true nature of the objects and subjects of human knowledge (Pramana-Sastra). It is also called Tarka-vidya (logic) and Vada-vidya or Vadartha (reasoned argument); and is included among the fourteen principal branches of learning.

The vada, is a candid friendly discussion (anuloma sambasha or sandhya sambasha) or debate in the spirit of: ’let’s sit-down and talk’. The other two are hostile arguments (vigrhya sambasha) between rivals who desperately want to win. Thus, while the goal of a vada is establishment of truth or an accepted doctrine; and that of the other two hostile debates (Jalpa and Vitanda) is seeking victory on the opponent.<ref name=":3" />

== विषयविस्तारः ॥ Detailed Discussion ==

According to the commentaries on the Nyaya Sutras, the debates and arguments are grouped under a broad head titled ‘Katha’. In Sanskrit, the term ‘Katha’, in general, translates as ‘to inform’, ‘to narrate’, ‘to address or to refer to somebody’. In the context of Nyaya Shatra, which provides the knowledge about the methods for presenting arguments (Vako-Vakya or Vada-vidya) as also the rules governing the debates, the term ‘Katha’ implies formal conversation (Sambasha) as in a debate. The conversation here is not in the casual manner as in day-to-day life. But, it is articulate, precise and well thought out utterances. Katha is described as ‘polemical conversation’, meaning that it is passionate and strongly worded, but a well balanced argument against or in favor of somebody or something. That is why; the discussions (Vada) are never simple. A Katha, in essence, is a reasoned and a well-structured philosophical discussion.<ref name=":3" />

=== संवादः ॥ Samvada ===

Of the four forms of discussions, Samvada is regarded the noblest type of dialogue that takes place. It is the discussion between an ardent seeker of truth and an enlightened teacher as in Sri Krishna-Arjuna samvada. The student here, does not question the teacher but questions his understanding for clarification. This type of discussion can occur only when the student surrenders himself completely at the feet of the teacher. Most of the ancient Indian texts are in this format.<ref name=":3" /><ref name=":1" />

Samvada is a dialogue that takes between the teacher and the taught in all earnestness. The one who approaches the teacher could be a disciple; student; friend (as in Krishna-Arjuna or Krishna-Uddhava) ; son (as in Shiva-Skanda or Uddalaka-Shvetaketu); or spouse (as in Shiva-Parvati or Yajnavalkya-Maitreyi); or anyone else seeking knowledge (as in Nachiketa-Yama or the six persons who approach Sage Pippalada in Prashna Upanishad). What characterizes the Samvada in such cases is the sincerity and eagerness of the learner; the humility in his/her approach; and the absolute trust in the teacher. The wise teacher, in turn, gracefully imparts instructions out of enormous love for the ardent seeker of truth.

Samvada is thus a dialogue that teaches, imparts instructions or passes on knowledge. The bulk of the Upanishad teachings have come down to us in the form of Samvada, which took place in varieties of contexts. Apart from intimate sessions where an illumined teacher imparts instructions to an aspirant, there are instances of varied kind, say, as when: a wife is curious to learn from her husband the secrets of immortality; a teenage boy approaches Yama to learn the truth of life and death; a Raja seeks instruction from an recluse sage who speaks from his experience; Brahmanas advanced in age and wisdom sit at the feet of a Kshatriya prince seeking instructions as also inspiration; and, at times, the sages are women who are approached by Rajas. There are other sorts of dialogues, say, when Jabala is taught by bulls and birds (Ch. Up 4.4-9), Upakosala by the sacred fires (Ch. Up. 4.10-15), and Baka is by a dog (Ch. Up 1.12).

The Bhagavad-Gita suggests that an ardent seeker of truth should approach a learned teacher in humility and seek instructions from him; question him repeatedly.<ref name=":3" /> <blockquote>तद्विद्धि प्रणिपातेन परिप्रश्नेन सेवया । उपदेक्ष्यन्ति ते ज्ञानं ज्ञानिनस्तत्त्वदर्शिनः ॥४-३४॥<ref>Bhagavad Gita, [https://sa.wikisource.org/wiki/%E0%A4%AD%E0%A4%97%E0%A4%B5%E0%A4%A6%E0%A5%8D%E0%A4%97%E0%A5%80%E0%A4%A4%E0%A4%BE/%E0%A4%9C%E0%A5%8D%E0%A4%9E%E0%A4%BE%E0%A4%A8%E0%A4%95%E0%A4%B0%E0%A5%8D%E0%A4%AE%E0%A4%B8%E0%A4%82%E0%A4%A8%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%B8%E0%A4%AF%E0%A5%8B%E0%A4%97%E0%A4%83 Chapter 4].</ref></blockquote><blockquote>''tadviddhi praṇipātena paripraśnena sevayā । upadekṣyanti te jñānaṁ jñāninastattvadarśinaḥ ॥4-34॥''</blockquote>The student questions the teacher not because he doubts the wisdom or the understanding of the teacher; nor is he/she questioning the authenticity of the teaching. The questions are asked with an open mind and guileless heart; and, are meant to clear doubts, and to gain a flawless understanding of the teaching. At the same time, the teacher is neither annoyed nor does he discourage the student from asking questions. On the other hand, he encourages the leaner to examine, enquire and test the teaching handed down to him. A true teacher, in a Samvada does not prescribe or proscribe. He lets the student have the freedom to think, to ponder over and to find out for himself the answers to his questions. A student needs humility, persistence, and honesty of purpose to go further and to arrive at his own understanding.<ref name=":3" />

Ideally, both the parties to the Vada should have mutual regard, respecting each other’s learning and status; and should participate with an open mind in order to explore various dimensions of the subject on hand; to examine it thoroughly by applying the accepted norms of logic and reasoning (Tarka), supported by passages from texts of undisputed authority (Shabda Pramana). The principal aim of a wholesome Vada is to resolve the conflict; and, to establish ‘what is true’. The proceedings of the Vada is characterized by politeness, courtesy and fair means of presenting the arguments. In other words, it is a healthy discussion.

Vatsayana in his commentary Nyaya Bhashya, says that congenial debate (Anuloma Sambasha) takes place when the opponent is not wrathful or malicious; but is learned, wise, eloquent and patient; is well versed in the art of persuasion and is gifted with sweet speech. As regards the benefits (Sambasha prashamsa or prayojana) of such peaceful and congenial debates: If a learned person debates with another scholar, both versed in the same subject, it would increase the depth of their knowledge, clear misapprehensions, if any, and lead them to find certain minor details which hitherto might have escaped their attention. Besides, it would heighten their zeal to study further; and bring happiness to both.

But, in cases where two scholars hold contrary views, the Vadin and Prati-vadin will each try very hard to establish the doctrine which he believes is true; and to convince the other to accept its veracity through fair and effective presentation and arguments. At the same time, each is willing to understand and appreciate the arguments of the other; and accept any merit they might find in it. In case, one is in doubt or unable to respond satisfactorily, one can take a break to re-group his position or to re-examine the issue to see whether he can refute the opponent’s argument more effectively or put up a sounder defense. And, if one is convinced that the doctrine and the argument presented by the opponent is valid, he adopts it with grace. And, at the end, one of the two might be proven wrong; or both could be right. In any case, they accept the outcome of the debate, whatever be it; and, part their ways without rancor.<ref name=":3" />

At the commencement of the Vada, the Judge or the arbiter (Madhyastha) lays down rules of the Vada. The disputants are required to honor those norms and regulations. They are also required to adhere to permissible devices; and not to breach certain agreed limits (Vada maryada). For instance; in the case of debates where the Vadin and Prati-vadin both belong to Vedic tradition it was not permissible to question the validity of the Vedas or the existence of Supreme being and the Atman. And, any position taken during the course of Vada should not contradict the Vedic injunctions.

In the case of the Vada where one belongs to Vedic tradition and the other to Non-Vedic traditions, they had to abide by the rules and discipline specifically laid down by the Madhyastha.

As mentioned earlier, according to Nyaya Sutra (1.2.1) Vada comprises defense and attack (Sadhana and Upalambha). One’s own thesis is defended by means of genuine criteria of knowledge (Pramana) and the antithesis (opponent’s theory) is refuted by negative dialectics of Tarka (logic). But, when defense or attack is employed excessively, merely for the sake of scoring a win, then there is the risk of the debate degenerating into Jalpa. It is at this stage in the Vada that the Madyastha might intervene to ensure that the participants, especially the one who is at the verge of defeat (Nigraha-sthana) do not resort to tricks such as quibbling (Chala), false rejoinder (Jati) etc. The Madyastha may even call off the Vada; and award to the candidate who in his view performed better. The Vada could be also treated as inconclusive (savyabhicara) and brought to an end if there is no possibility of reaching a fair decision; or the very subject to be discussed is disputed (Viruddha); or when arguments stray away from the subject that is slated for discussion (prakarana-atita) ; or when the debate prolongs beyond a reasonable (Kalatita).

As mentioned earlier, according to Nyaya Sutra (1.2.1) Vada comprises defense and attack (Sadhana and Upalambha). One’s own thesis is defended by means of genuine criteria of knowledge (Pramana) and the antithesis (opponent’s theory) is refuted by negative dialectics of Tarka (logic). But, when defense or attack is employed excessively, merely for the sake of scoring a win, then there is the risk of the debate degenerating into Jalpa. It is at this stage in the Vada that the Madhyastha might intervene to ensure that the participants, especially the one who is on the verge of defeat (Nigraha-sthana) do not resort to tricks such as quibbling (Chala), false rejoinder (Jati) etc. The Madhyastha may even call off the Vada; and award to the candidate who in his view performed better.

In this context, it is said the debate could be treated as concluded and one side declared defeated:   

When one party is silenced in the process, the thesis stays as proven. Hence, in Vada, there is no explicit ‘defeat’ as such. The sense of defeat (Nigrahasthana) becomes apparent when there are contradictions in logical reasoning (hetvabhasa); and the debate falls silent. And, at the end, one of the two might be proven wrong; or both could be right. In any case, when one is convinced that the doctrine and the argument presented by the opponent are valid, he adopts it with grace. Ideally, whatever might be the outcome of a Vada, it should be accepted; and, both – Vadin and Prativadin – should part their ways without rancor.

For example, the most celebrated Vada is said to be the one that took place between the young Sri Shankara and the distinguished Mimamsa scholar, householder, Mandana Mishra. Considering the young age of the opponent, Mandana Mishra generously offered Sri Shankara the option to select the Madyastha (Judge) for the ensuing debate. Sri Shankara, who had great respect for the righteousness of Mandana Mishra, chose his wife Bharati Devi, a wise and learned person. During the course of the lengthy debate when Mandana Mishra seemed to be nearing Nigrahasthana (clincher) Bharati Devi raised questions about marital obligations. Sri Shankara being a sanyasi had, of course, no knowledge in such matters. He requested for and obtained a ‘break’ to study and to understand the issue. It is said; he returned after some time equipped with the newly acquired knowledge, renewed the Vada and won it. Thereafter, Mandana Mishra and Bharati Devi accepted Sri Shankara as their teacher, with grace and respect.]<ref name=":3" />

==== जल्पसाधनानि ॥ Means of disputation ====

Both the Vadin and the Prativadin work hard to establish their thesis through direct and indirect proofs. In Jalpa, the Pramana-s, the means of valid knowledge do not have much role to play. The arguments in Jalpa relay more on negation or negative tactics, such as: discrediting the rival argument, misleading the opponent or willfully misinterpreting rival’s explanations. The main thrust of the arguments in Jalpa is not so much as to establish the thesis directly, as to disprove or refute the rival’s thesis, through circumvention. The reason why Jalpa is labeled as tricky is that apart from traditional means of proving one’s thesis and for refuting the opponent’s thesis, the debater can use elusive and distracting devices such as: quibbling or hair-splitting (Chala); inappropriate rejoinders (Jati), and any kind of ruse that tries to outwit and disqualify the opponent (nigrahasthana), circumvention, false generalization and showing the unfitness of the opponent to argue; without, however, establishing his own thesis.

=== वितण्डा ॥ Vitanda ===

And, Vitanda is the worst type of argument or squabbling descending to the level of quarrel and trickery. It is described as a destructive type of argument; the sole aim of each party being not only to inflict defeat on the opponent but also to demolish and humiliate him. The Vaitandika, the debater who employs Vitanda, is basically a refuter; he relentlessly goes on refuting whatever the proponent says. He has no thesis of his own – either to put forward or to defend. The aggressive Vaitandika goes on picking holes in the rival’s arguments and destabilizes his position, without any attempt to offer an alternate thesis. <ref name=":3" /> It is said that,<blockquote>स जल्पो वितण्डा भवति किं विशेषणः प्रतिपक्षस्थापनया हीनः ।<ref name=":5" /></blockquote><blockquote>''a jalpo vitaṇḍā bhavati kiṁ viśeṣaṇaḥ pratipakṣasthāpanayā hīnaḥ ।''</blockquote>Meaning: That Jalpa (disputation) becomes Vitanda (wrangling) which is devoid of counter conception.  

Vitanda is some what peculier.<ref name=":1" /> In the case of Jalpa the contending parties have a position of their own, fight hard to defend it, and aim to make the rival accept it, by whatever means. However, in the Vitanda, the disputant has neither a position of his own nor is he trying to defend any specific thesis. He is merely trying to derange and humiliate the other party to the debate.<ref name=":3" />The focus is to prove that the opponent is not qualified to discuss and that there is no credibility for the opponent.<ref name=":1" /><ref name=":2" />

It is mentioned here that the Wrangler does not establish the view (that which he himself holds), but only goes on to criticize the other person. Hence, it seems as though a disputation without a counter conception is Vitanda. However, according to Tatparya Tika, when the wrangler confines himself to merely criticizing the opponent's view, he does so with the idea that when the opponent's view has been rejected as wrong, it would follow as a necessary consequence that his own view is right, so he does have a view of this own; but it is stated in wrangling, only in the form of the attack on the other view, this criticism, being figuratively spoken of as his 'view'. So, the meaning is that though the wrangler has a view of his own, yet he does not make any attempt at establishing it, apart from the attack that he directs against the other view. Hence, it is only right to speak of there being no establishing of his own view but it would be wrong to say that there is no other view.<ref name=":4" />

Sometimes he might pick up a thesis just for argument’s sake, even though he may have no faith in the truth of his own argument. Also, both the participants in a Vitanda are prepared to resort to mean tactics in order to mislead, browbeat the opponent by fallacies (hetvabhasa); by attacking the opponents statement by willful misrepresentation (Chala); ill-timed rejoinders (Atita-kala) and, make the opponent ‘bite the dust’. It is virtually akin to a ‘no-holds-barred’ sort of street fight. The ethereal values such as: truth, honesty, mutual respect and such others are conspicuously absent here.<ref name=":3" />

In Akshapada’s Nyaya-Sutra (1.2.3), Vitanda is classified as a ’bad’ or hostile argument (Vigrahya sambasha) or wrangling. In terms of merit, it is rated inferior to Jalpa, which also employs such trickery as quibbling and illegitimate rejoinder. While Jalpa tries to argue for the success of its thesis by whatever means, Vitanda does not seriously attempt to put up any counter-thesis. That is because, its debater has no thesis of his own to put forward. In other words, the debater here tries to ensure his victory simply by refuting or demolishing the thesis put forward by the other side, by browbeating or misleading or ridiculing the opponent. The whole purpose its exercise seems to be to prove the opponent wrong and incompetent; and to humiliate him. Vitanda is therefore termed as a destructive debate.
