論証

• Reading: ろんしょう
• Romaji: ronsho
• Kanji breakdown: 論 (ron) — argument, discussion, theory; 証 (shou) — proof, evidence, certify
• Pronunciation: /ɾon.ɕoː/

Meaning

Proof; demonstration; argument; logical reasoning. The process of establishing the truth of a proposition through structured, evidence-based argumentation.

In logic and philosophy, 論証 refers to a sequence of statements where premises lead to a conclusion. Distinct from 立証 (which emphasises empirical evidence) and 証明 (mathematical proof), 論証 focuses on the structure and coherence of the argument itself. A valid 論証 follows the rules of formal logic, while a sound 論証 also has true premises. Used widely in academic writing, debate, philosophy, and legal argumentation.

Examples

1. 彼の論文は緻密な論証によって支えられており、反証が困難だと評価されている。 His thesis is supported by meticulous argumentation and has been assessed as difficult to refute.
2. 哲学の授業では、前提から結論を導く論証の形式を学ぶことが基礎となる。 In philosophy classes, learning the form of argumentation that derives conclusions from premises is foundational.
3. 感情的な訴えではなく、論理的な論証によって相手を説得することが重要だ。 It is important to persuade others through logical argumentation rather than emotional appeals.
