Logic: Laws and Forms of Correct Thinking

Elements of Argumentation Theory

Argumentation represents a logical-communicative procedure for substantiating (or refuting) a particular viewpoint through the use of other knowledge that is beyond doubt in its truthfulness. The subjects involved in the process of argumentation are: the proponent—who puts forward and defends a specific assertion; the opponent—who expresses disagreement with this assertion; and the audience—who conveys their agreement or disagreement with the positions of both parties.

The logical elements of argumentation consist of: a thesis—a particular proposition put forth by the proponent, the truth or falsity of which they seek to justify; arguments (evidence)—judgments whose truth has already been established and is indisputable, allowing them to substantiate the thesis; and demonstration—the logical connection between the thesis and the arguments, which is realized in the form of inferences.

The procedure of argumentation is a competition between two sides occupying different positions regarding the thesis. Therefore, it combines two opposing operations: justification—a logical procedure for establishing the truth of the thesis by deriving it from the arguments; and refutation (critique)—a logical operation aimed at dismantling the justification, proving the falsity of the thesis, or the inadequacy of the demonstration. Both proof and critique are governed by specific rules, the violation of which leads to various kinds of errors: paralogisms—unintentional violations of logical rules, and sophisms—intentional violations.

The rules of argumentation are divided into those concerning the thesis, those concerning the arguments, and those concerning the demonstration.

Regarding the thesis, there are two rules: the rule of the thesis’s definiteness and its invariability. With respect to arguments, the following rules must be adhered to: the arguments must be credible; the truth of the arguments should be determined independently of the thesis; one argument should not contradict another and must be sufficient to support the thesis. As for the demonstration, an unconditional adherence to the rules of inference is a necessary condition.

A complex form of argumentation is the debate. There are both correct and incorrect methods of conducting a debate. Correct methods, which align with the rules of logic and are permitted by moral norms, include: taking the initiative during the debate (following the principle that "the best defense is a good offense"); insisting on the very evidence that reveals the opponent's embarrassment and confusion; attacking the most vulnerable points of their arguments; "buying time" by delaying agreement with the opponent’s evidence, thereby gathering one’s thoughts; using the opponent's arguments to refute their own position; and shifting the burden of argumentation onto the opponent based on the principle of "you prove that your thesis is true."

In contrast, incorrect and prohibited means, referred to as "forbidden tricks," include: obstruction—depriving the opponent of the opportunity to speak; "psychological diversion"—attempting to destabilize the opponent; "exploiting certain human flaws," such as a tendency toward conformity, susceptibility to flattery, or fear of losing face; "willful misunderstanding of the thesis or its loss"; "logical diversion"—redirecting attention to discuss another issue; appeals to force in the form of threats, pity, or authority; and personal attacks against the opponent.

General recommendations for conducting a debate include: clarifying the meaning and relevance of the debate; identifying common starting positions for both parties; carefully selecting arguments; the ability to listen to the opponent; maintaining respect toward the opponent; and self-control.

A high culture of discourse is one of the most significant characteristics of a citizen in a democratic society, and knowledge of logic is an essential condition for the effectiveness and correctness of a debate.
