• Pinyin (with tone marks): tuī lǐ
• Part of Speech: Verb / Noun
• HSK Level: HSK 5
• Concise Definition: To infer or deduce based on facts; the process of logical reasoning or inference.
• In a Nutshell: 推理 (tuīlǐ) is the act of using what you know to figure out what you don't. Think of a detective connecting clues to identify a suspect, or a scientist using data to form a conclusion. As a verb, it means “to reason” or “to infer.” As a noun, it refers to “the reasoning” itself. It’s a structured, logical way of thinking that moves from evidence to conclusion.

• 推 (tuī): The original meaning is “to push” or “to shove.” In a conceptual sense, it extends to mean “to push forward” an idea, “to promote,” or “to infer.” It implies a forward motion from a starting point.
• 理 (lǐ): This character is central to many intellectual concepts in Chinese. It means “reason,” “logic,” “principle,” or “truth.” It's the same `理` found in `道理 (dàolǐ - reason/principle)` and `物理 (wùlǐ - physics)`.

When combined, 推理 (tuīlǐ) literally means “to push the logic forward.” This beautifully illustrates the concept: you start with facts or premises and “push” them along a logical path to arrive at a new understanding or conclusion.

While logic is a universal human faculty, its emphasis and style can differ across cultures. In the West, formal, explicit, Aristotelian logic is the foundation of “reasoning.” In China, while modern education has fully embraced this framework, traditional thought often incorporated more holistic or analogical reasoning. 推理 (tuīlǐ) in modern China is a key skill, highly valued in science, law, and business. It is seen as a cornerstone of modernization and critical thought. However, it can be subtly different from the Western concept of “critical thinking.” “Critical thinking” often carries a connotation of questioning authority and foundational assumptions. 推理 (tuīlǐ), on the other hand, tends to focus more purely on the mechanical process of drawing valid conclusions from a *given* set of information or premises. It's less about challenging the premises and more about expertly navigating the path from the premises to the conclusion. For a learner, understanding 推理 (tuīlǐ) is crucial for engaging in debates, understanding complex texts, and even appreciating Chinese mystery and crime dramas (called 推理剧 - tuīlǐjù), which are incredibly popular.

推理 (tuīlǐ) is a versatile word used in both formal and informal contexts.

• As a Noun (Reasoning/Inference):
  • In academic or professional settings: “你的推理过程有漏洞。” (Nǐ de tuīlǐ guòchéng yǒu lòudòng. - There is a flaw in your reasoning process.)
  • Talking about entertainment: “我喜欢看推理小说。” (Wǒ xǐhuān kàn tuīlǐ xiǎoshuō. - I like to read mystery/detective novels.)
• As a Verb (To Reason/To Infer):
  • In problem-solving: “让我们根据现有线索推理一下。” (Ràng wǒmen gēnjù xiànyǒu xiànsuǒ tuīlǐ yīxià. - Let's do some reasoning based on the current clues.)
  • Expressing a conclusion: “我推理他就是凶手。” (Wǒ tuīlǐ tā jiùshì xiōngshǒu. - I deduce that he is the murderer.)

The term is neutral and describes a mental process. Its connotation (good or bad) depends on adjectives used with it, such as 严密的推理 (yánmì de tuīlǐ - rigorous reasoning) or 错误的推理 (cuòwù de tuīlǐ - flawed reasoning).

• Example 1:
  • 警察正在根据证据进行推理。
  • Pinyin: Jǐngchá zhèngzài gēnjù zhèngjù jìnxíng tuīlǐ.
  • English: The police are conducting their reasoning based on the evidence.
  • Analysis: Here, 推理 is used as a noun in the phrase `进行推理 (jìnxíng tuīlǐ)`, a formal way to say “to carry out reasoning.” This is common in news reports or official contexts.
• Example 2:
  • 你的推理听起来很有道理。
  • Pinyin: Nǐ de tuīlǐ tīng qǐlái hěn yǒu dàolǐ.
  • English: Your reasoning sounds very logical.
  • Analysis: 推理 is a noun here, meaning “reasoning” or “line of thought.” `有道理 (yǒu dàolǐ)` means “makes sense” or “is reasonable.”
• Example 3:
  • 从他的话中，我推理出他不想去。
  • Pinyin: Cóng tā de huà zhōng, wǒ tuīlǐ chū tā bùxiǎng qù.
  • English: From his words, I inferred that he doesn't want to go.
  • Analysis: Here, 推理 is a verb. The directional complement `出 (chū)` indicates that a conclusion has been “brought out” or derived from the process of reasoning.
• Example 4:
  • 这道数学题需要很强的逻辑推理能力。
  • Pinyin: Zhè dào shùxué tí xūyào hěn qiáng de luójí tuīlǐ nénglì.
  • English: This math problem requires strong logical reasoning ability.
  • Analysis: 推理 is often paired with `逻辑 (luójí - logic)` to be more specific. `推理能力 (tuīlǐ nénglì)` is a common collocation meaning “reasoning ability.”
• Example 5:
  • 福尔摩斯擅长推理。
  • Pinyin: Fú'ěrmósī shàncháng tuīlǐ.
  • English: Sherlock Holmes is good at deduction.
  • Analysis: A simple sentence using the verb `擅长 (shàncháng)`, meaning “to be good at.” This shows 推理 as a skill.
• Example 6:
  • 这部电影是一部经典的推理片。
  • Pinyin: Zhè bù diànyǐng shì yī bù jīngdiǎn de tuīlǐ piàn.
  • English: This movie is a classic detective/mystery film.
  • Analysis: 推理 is used as an adjective here to describe a genre. `推理小说 (tuīlǐ xiǎoshuō)`, `推理剧 (tuīlǐjù)`, and `推理片 (tuīlǐ piàn)` all refer to the mystery/detective genre.
• Example 7:
  • 仅凭猜测而不是推理是无法解决问题的。
  • Pinyin: Jǐn píng cāicè ér bùshì tuīlǐ shì wúfǎ jiějué wèntí de.
  • English: You can't solve the problem by just guessing instead of reasoning.
  • Analysis: This sentence directly contrasts 推理 (reasoning) with `猜测 (cāicè - guessing)`, highlighting the evidence-based nature of 推理.
• Example 8:
  • 他的推理有一个致命的缺陷。
  • Pinyin: Tā de tuīlǐ yǒu yīgè zhìmìng de quēxiàn.
  • English: His reasoning has a fatal flaw.
  • Analysis: Shows how 推理 (as a noun) can be evaluated. `致命的缺陷 (zhìmìng de quēxiàn)` is a strong phrase for “fatal flaw.”
• Example 9:
  • 我们可以推理出，如果A大于B，B大于C，那么A一定大于C。
  • Pinyin: Wǒmen kěyǐ tuīlǐ chū, rúguǒ A dàyú B, B dàyú C, nàme A yīdìng dàyú C.
  • English: We can deduce that if A is greater than B, and B is greater than C, then A must be greater than C.
  • Analysis: This demonstrates 推理 in a purely logical, almost mathematical context.
• Example 10:
  • 孩子们的推理能力需要通过教育来培养。
  • Pinyin: Háizimen de tuīlǐ nénglì xūyào tōngguò jiàoyù lái péiyǎng.
  • English: Children's reasoning skills need to be cultivated through education.
  • Analysis: This highlights the view of 推理能力 (reasoning ability) as a skill that can be developed, particularly in an educational context.

• 推理 (tuīlǐ) vs. 思考 (sīkǎo):
  • `思考 (sīkǎo)` means “to think” in a general sense. It can be about anything: “I'm thinking about what to eat.”
  • 推理 (tuīlǐ) is a specific *type* of thinking: structured, logical, and evidence-based. You don't 推理 what to eat for lunch, but you might 推理 that a restaurant is popular because there's a long line.
• 推理 (tuīlǐ) vs. 理由 (lǐyóu):
  • This is a critical distinction for English speakers. 推理 (tuīlǐ) is the process of reasoning. `理由 (lǐyóu)` is the reason or justification for something.
  • Incorrect: 我迟到的推理是堵车了。(Wǒ chídào de tuīlǐ shì dǔchē le.)
  • Correct: 我迟到的理由是堵车了。(Wǒ chídào de lǐyóu shì dǔchē le. - The reason I was late was traffic.)
  • Think of it this way: you use 推理 to arrive at a conclusion, and then you state your `理由` to explain that conclusion to someone else.
• 推理 (tuīlǐ) vs. 分析 (fēnxī):
  • `分析 (fēnxī)` means “to analyze,” which is to break something complex down into smaller parts to understand it.
  • Analysis is often the first step, and reasoning is the second. You `分析` the evidence (break it down), and then you `推理` from that analysis to form a conclusion (build it back up into a new idea).

• 逻辑 (luójí): Logic. A loanword from English. It refers to the formal system or principles of valid reasoning that underpin 推理.
• 分析 (fēnxī): To analyze. The act of breaking down information, which often precedes 推理.
• 判断 (pànduàn): To judge; judgment. This is often the result or conclusion of the 推理 process.
• 理由 (lǐyóu): Reason; justification. The 'why' you give for a belief or action, distinct from the mental process of 推理.
• 证据 (zhèngjù): Evidence; proof. The factual basis required to perform 推理.
• 推断 (tuīduàn): To infer; inference. A very close synonym for 推理 and often used interchangeably. 推断 can sometimes feel slightly more focused on the resulting conclusion.
• 演绎 (yǎnyì): Deduction. A specific type of 推理 that moves from a general rule to a specific conclusion (e.g., All men are mortal. Socrates is a man. Therefore, Socrates is mortal).
• 归纳 (guīnà): Induction. A specific type of 推理 that moves from specific observations to a general conclusion (e.g., The sun has risen every day so far, so the sun will rise tomorrow).
• 思考 (sīkǎo): To think. The general, broad category of mental activity where 推理 is a specific, structured part.
