欢迎阅读 Year 8 CAIE 哲学复习指南。本文将梳理你会在课程中遇到的核心思想：从什么是哲学，到我们如何获取知识、做出伦理决策以及构建好的论证。每个小节都配有英文解释和对应的中文段落，帮助你同时掌握概念与学科词汇。
1. What Is Philosophy? | 什么是哲学？
Philosophy is the love of wisdom. It is not about accepting answers without question but about asking 'why' and 'how' with careful reasoning. Philosophers examine fundamental questions about existence, knowledge, values, reason, and language. In Year 8, you begin this journey by learning to think critically and to spot assumptions in everyday beliefs.
哲学是爱智慧。它不是不加质疑地接受答案，而是用严谨的推理去追问“为什么”和“如何”。哲学家探究关于存在、知识、价值、理性与语言的根本性问题。在 Year 8，你通过学会批判性思考、发现日常信念中的假设，开启这段旅程。
2. Branches of Philosophy | 哲学的主要分支
Philosophy is traditionally divided into several branches. Epistemology asks what knowledge is and how we acquire it. Metaphysics explores the nature of reality. Ethics examines how we ought to live. Logic studies correct reasoning. Familiarity with these branches helps you see how different questions belong to different areas of enquiry.
哲学传统上分为若干分支。认识论追问什么是知识以及我们如何获得知识。形而上学探究实在的本性。伦理学考察我们应当如何生活。逻辑学研究正确的推理。熟悉这些分支有助于你识别不同问题属于不同的探究领域。
- Epistemology – theory of knowledge. / 认识论 – 知识论。
- Metaphysics – ultimate nature of reality. / 形而上学 – 实在的终极本性。
- Ethics – moral philosophy. / 伦理学 – 道德哲学。
- Logic – principles of valid reasoning. / 逻辑学 – 有效推理的原则。
- Aesthetics – nature of beauty and art. / 美学 – 美与艺术的本质。
3. Epistemology: How Do We Know? | 认识论：我们如何知道？
Epistemology asks how we can be sure that what we believe is true. The classic definition of knowledge is 'justified true belief'. For something to count as knowledge, you must believe it, it must be true, and you must have good reasons or evidence for it. In Year 8 you examine simple cases: can we trust our senses? Can we know something without seeing it?
认识论追问我们如何确定自己所信的是真的。知识的经典定义是“被证成的真信念”。某件事要算作知识，你必须相信它、它必须为真，而且你必须拥有好的理由或证据。在 Year 8 你会考察简单案例：我们可以信任感官吗？我们没有看见某物，能知道它吗？
A simple model: S knows that P if and only if (i) P is true, (ii) S believes that P, and (iii) S has justification for believing P. Later you will meet challenges to this model.
简单模型：S 知道 P 当且仅当 (i) P 为真、(ii) S 相信 P 且 (iii) S 拥有相信 P 的证据。之后你会遇到对这个模型的挑战。
4. The Problem of Perception | 感知问题
Our senses can deceive us – dreams, illusions, and mirages show that things are not always as they appear. Philosophers ask: if our senses sometimes mislead us, how can we ever be certain of the external world? René Descartes imagined an 'evil demon' that could make all our experiences an illusion. This sceptical challenge pushes us to find secure foundations for knowledge.
我们的感官会欺骗我们——梦境、错觉和海市蜃楼表明，事物并不总是如其显现的那样。哲学家追问：如果感官有时误导我们，我们怎能确定外部世界的存在？勒内·笛卡儿构想了一个“恶魔”，可以使我们所有的经验都成为幻觉。这种怀疑论的挑战促使我们去寻找知识的可靠基础。
Descartes' famous conclusion was: 'I think, therefore I am.'
笛卡儿著名的结论是：“我思，故我在。”
5. Reality and Appearance | 现实与表象
Plato's allegory of the cave illustrates the difference between appearance and reality. Prisoners see only shadows on a wall and mistake them for the real objects. The philosopher, like a prisoner who escapes, discovers a deeper truth. In Year 8, this allegory helps you think about whether our everyday world is all there is, or if there is a truer reality beyond what we perceive.
柏拉图的洞穴寓言说明了表象与现实的区别。囚徒只看见墙上的影子，却把它们当成真实的物体。哲学家就像那个逃出的囚徒，发现了更深层的真理。在 Year 8，这个寓言有助于你思考：我们日常的世界就是全部存在吗，还是有一个超越我们感知的更真实的实在？
| Concept / 概念 | Description / 描述 |
|---|---|
| Appearance (Phenomena) / 现象 | How things seem to us through the senses / 事物通过感官向我们显现的方式 |
| Reality (Noumena) / 本体 | Things as they are in themselves, independent of our perception / 事物自身的样子，独立于我们的感知 |
6. Mind and Body | 心灵与身体
Are your mind and your body the same thing, or are they different substances? Dualists argue that the mind is non-physical, whereas physicalists claim that mental states are just brain states. In Year 8 you explore thought experiments like the 'brain in a vat' to consider whether you could be just a brain thinking, without a body.
你的心灵和你的身体是同一个东西，还是不同的实体？二元论者主张心灵是非物质的，而物理主义者声称心理状态不过是大脑状态。在 Year 8，你会通过“缸中之脑”等思想实验来思考：你是否可能只是一个正在思考的大脑，而无需身体？
This topic connects to personal identity: what makes you the same person over time – your memories, your body, or something else?
这个主题与人格同一性相关联：是什么让你随着时间流逝依然是同一个人——你的记忆、你的身体，还是别的什么？
7. Ethics: Right and Wrong | 伦理学：对与错
Ethics is about how we should act. Three major approaches are useful for Year 8: consequentialism, deontology, and virtue ethics. Consequentialists judge actions by their outcomes, deontologists by whether they follow moral rules, and virtue ethicists by the character of the person acting. Understanding these theories helps you analyse everyday moral problems.
伦理学关乎我们应当如何行动。对 Year 8 来说，有三种主要进路值得了解：后果论、义务论和德性伦理学。后果论者依据结果来评判行为，义务论者看行为是否遵循道德规则，德性伦理学家则关注行为者的品格。理解这些理论有助于你分析日常道德问题。
- Utilitarianism (Consequentialism): Maximise happiness for the greatest number. / 功利主义（后果论）：为最大多数人谋求最大幸福。
- Deontology: Follow duties and rules, e.g., 'Do not lie'. (Kant) / 义务论：遵循义务和规则，如“不要说谎”。（康德）
- Virtue Ethics: Cultivate good character traits, e.g., courage, honesty. (Aristotle) / 德性伦理学：培养良好的品格，如勇敢、诚实。（亚里士多德）
8. Moral Dilemmas | 道德困境
Moral dilemmas reveal conflicts between ethical principles. The famous 'trolley problem' asks whether you should divert a runaway trolley to kill one person instead of five. It tests the difference between actively causing harm and allowing harm to happen. In Year 8, discussing such dilemmas sharpens your ability to give reasons and to appreciate different viewpoints.
道德困境揭示了伦理原则之间的冲突。著名的“电车难题”问道：你应当让失控的电车转向，杀死一个人而不是五个人吗？它检验了主动造成伤害与放任伤害发生之间的区别。在 Year 8，讨论这类困境能够锻炼你给出理由的能力，并让你学会欣赏不同的观点。
When analysing a dilemma, ask: (1) What makes the action right or wrong? (2) What are the consequences? (3) Would you want everyone to act in that way?
分析困境时，请问：(1) 是什么使得该行为对或错？(2) 后果是什么？(3) 你希望每个人都那样行动吗？
9. Logic and Argument | 逻辑与论证
Philosophy relies on arguments, not mere opinions. An argument is a set of statements where some (premises) are offered in support of another (conclusion). A good argument is logically valid and has true premises. Year 8 students learn to identify premises and conclusions in short passages and to check whether the reasoning makes sense.
哲学依赖论证，而非单纯的观点。一个论证是一组陈述，其中一些（前提）被用来支持另一个（结论）。一个好的论证是逻辑有效的且拥有真实的前提。Year 8 学生要学会识别短文中的前提和结论，并检查推理是否有道理。
Premise 1: All humans are mortal. Premise 2: Socrates is human. Conclusion: Therefore, Socrates is mortal.
前提 1：所有人都会死。前提 2：苏格拉底是人。结论：所以，苏格拉底会死。
10. Common Fallacies | 常见谬误
A fallacy is a mistake in reasoning that makes an argument unsound. Recognising fallacies protects you from being persuaded by bad arguments. In Year 8 you will learn a few common ones: ad hominem (attacking the person instead of the argument), straw man (misrepresenting an opponent's view), and slippery slope (assuming one step inevitably leads to disaster).
谬误是推理中的错误，使论证不成立。识别谬误可以保护你不被糟糕的论证说服。在 Year 8，你会学到一些常见的谬误：人身攻击（攻击对方本人而非论证）、稻草人（曲解对方的观点）和滑坡谬误（假定一步必然导致灾难）。
| Fallacy / 谬误 | Meaning / 含义 | Example / 示例 |
|---|---|---|
| Ad hominem / 人身攻击 | Attacking the speaker, not the argument / 攻击说话者而非论证 | 'You are wrong because you are young.' / “你错了，因为你太年轻。” |
| Straw man / 稻草人 | Distorting the opponent's position / 扭曲对方的立场 | 'You want to reduce homework? So you want students to learn nothing!' / “你想减少作业？那你就是希望学生什么也不学！” |
| Slippery slope / 滑坡谬误 | Suggesting minor action leads to extreme outcome / 暗示小行为导致极端后果 | 'If we allow late homework, soon nobody will submit anything.' / “如果我们允许迟交作业，很快就没有人会交任何东西了。” |
11. Political Philosophy: Justice | 政治哲学：正义
Political philosophy wonders how society should be organised. The concept of justice is central – what do people deserve, and how should resources be distributed? You may meet John Rawls' idea of a 'veil of ignorance', where we design a fair society without knowing our own position in it. This encourages thinking about fairness from an impartial viewpoint.
政治哲学思考社会应如何组织。正义的概念是核心——人们应当得到什么，资源又该如何分配？你可能会接触到约翰·罗尔斯的“无知之幕”思想：我们在不知道自己社会地位的情况下设计公正的社会。这鼓励人们从无偏私的视角思考公平。
Another key idea is the social contract: the notion that people agree to give up some freedom in exchange for security and order. Year 8 discussions can link to rules in schools and communities.
另一个关键观念是社会契约：人们同意放弃一部分自由以换取安全与秩序。Year 8 的讨论可以联系到学校和社区中的规则。
12. Philosophy in Everyday Life | 日常生活中的哲学
Philosophy is not just in books; it is in the questions you ask when you wonder whether a news report is biased, when you argue with a friend about what is fair, or when you reflect on what makes you happy. Practising philosophical thinking improves your ability to listen, to question, and to co-operate with others in solving problems.
哲学不只存在于书本里，它就在你提出的问题中：当你怀疑一篇新闻报道是否有偏见时，当你和朋友争论怎么样才算公平时，或者当你反思什么让你幸福时。练习哲学思考能提高你倾听、质疑和合作解决问题的能力。
The skills you build in Year 8 – critical reasoning, open-mindedness, and respectful dialogue – are life-long tools that will serve you well in any subject and in your daily life.
你在 Year 8 培养的技能——批判性推理、开放心态和尊重他人的对话——是终身的工具，无论在任何学科还是日常生活中都将使你受益。
