📚 Pre-U CAIE Philosophy: Case Analysis Practical Exercises | Pre-U CAIE 哲学：案例分析实战演练
Philosophy at Pre-U CAIE level demands far more than memorising famous quotes or doctrines. It requires the ability to enter unfamiliar scenarios, identify the philosophical tension at their heart, and construct rigorous, evaluative arguments in response. The case study or thought experiment is at the centre of this skill. This article offers a practical walk‑through of how to unpack, analyse and write about philosophical cases, drawing on classic examples and exam‑ready strategies.
Pre‑U CAIE 阶段的哲学远远不只是背诵名言或学说。它要求你能够进入陌生情境，找出其核心的哲学张力，并构造严谨、评估性的论证来回应。案例分析或思想实验正是这一技能的核心。本文将带你实打实地演练如何拆解、分析哲学案例并以此写作，引用经典例子和考试实用的策略。
1. What Is a Philosophical Case Study? | 什么是哲学案例研究？
A philosophical case study is a structured scenario, often simplified and deliberately odd, that isolates a conceptual puzzle. It asks you to test principles against imagined facts. In CAIE Pre-U, such cases appear across epistemology, ethics, metaphysics and philosophy of mind.
哲学案例研究是一个结构化的情境，通常被简化并有意显得怪异，用以孤立出一个概念上的难题。它要求你对照想象中的事实来检验原则。在 CAIE Pre‑U 中，这样的案例出现在认识论、伦理学、形而上学和心灵哲学等领域。
The case is not an end in itself; it is a tool to reveal weaknesses in a theory or to force us to refine our definitions of concepts such as knowledge, personal identity or moral rightness.
案例本身不是目的；它是用来揭示理论弱点或迫使我们精炼诸如知识、人格同一性或道德正当性等概念定义的工具。
2. The Trolley Problem: A Classic Ethical Case | 电车难题：经典伦理案例
Few thought experiments are as iconic as the Trolley Problem. A runaway trolley is heading towards five people tied to the track. You can pull a lever to divert the trolley onto a side track, where one person is tied. Should you pull the lever?
很少有思想实验像电车难题那样具有标志性。一辆失控的电车正冲向被绑在轨道上的五个人。你可以拉动拉杆使电车转向侧轨，那里绑着一个人。你应该拉动拉杆吗？
This case pits utilitarian reasoning (saving more lives) against deontological concerns (actively killing someone as a means). It forces you to consider whether the distinction between doing and allowing harm carries moral weight.
这个案例将使功利主义推理（拯救更多生命）与义务论关怀（主动将某人作为手段而杀害）对立起来。它迫使你思考’做’与’允许’伤害之间的区别是否具有道德分量。
A variant, the ‘fat man’ version, asks whether you should push a large person off a bridge to stop the trolley. Here the physical contact and direct use of a person change many people’s intuitions, even though the calculus appears similar.
一个变体，即’胖子’版本，问你是否应该把一个大个子推下桥去挡住电车。此时身体接触和直接利用某人改变了许多人的直觉，尽管计算起来似乎相似。
3. Analysing the Trolley Problem: Step by Step | 逐步分析电车难题
Begin by identifying the ethical concepts at play: utility, rights, double effect, and the agent’s integrity. Map the structure of the argument each side would offer. A utilitarian would say: one death is less bad than five deaths, therefore pulling the lever is obligatory.
首先识别涉及的伦理概念：效用、权利、双重效果以及行动者的完整性。描绘各方可能给出的论证结构。功利主义者会说：一人死亡比五人死亡糟糕程度更轻，因此拉动拉杆是义务性的。
Then, consider the counter‑arguments. A Kantian might object that the single person on the side track is being used merely as a means to save five, violating the categorical imperative. Reflect on whether the physical distance and machinery of the lever make a moral difference.
然后，考虑反驳论点。康德主义者可能会反对说，侧轨上的那一个人仅仅被用作拯救五人的手段，违背了定言命令。反思拉杆带来的物理距离和机械操作是否在道德上有所不同。
Strong answers do not stop at describing the clash; they evaluate which framework gives a more compelling account of our considered moral judgments and why. Use the case to illuminate deeper questions about the nature of moral reasoning.
好的答案不会止步于描述冲突；它们会评估哪个框架对我们深思熟虑的道德判断给出了更具说服力的解释以及原因。利用案例来阐明有关道德推理本质的更深层问题。
4. The Gettier Problem: Challenging ‘Justified True Belief’ | 盖梯尔问题：挑战“确证的真信念”
Since Plato, many philosophers held that knowledge is justified true belief (JTB). In 1963, Edmund Gettier published a two‑page paper presenting cases where someone has a justified true belief, yet intuitively lacks knowledge. These cases revolutionised epistemology.
自柏拉图以来，许多哲学家认为知识就是确证的真信念（JTB）。1963年，埃德蒙·盖梯尔发表了一篇仅两页的论文，提出了某人拥有确证的真信念但在直觉上却缺乏知识的情境。这些案例彻底改变了认识论。
In a typical Gettier case, Smith has strong evidence that Jones owns a Ford (Jones has always driven a Ford, etc.). Smith then forms the belief ‘Jones owns a Ford, or Brown is in Barcelona’. It turns out Jones no longer owns a Ford, yet by sheer luck Brown is indeed in Barcelona. Smith’s belief is true and justified, but we hesitate to call it knowledge.
在一个典型的盖梯尔案例中，史密斯有很强的证据相信琼斯拥有一辆福特车（琼斯一直开福特等）。然后史密斯形成信念：’琼斯拥有一辆福特车，或者布朗在巴塞罗那’。结果琼斯不再拥有福特车，但纯粹靠运气布朗恰好真的在巴塞罗那。史密斯的信念是真的且得到确证，但我们难以称其为知识。
5. Dissecting Gettier Cases: The Role of Luck | 剖析盖梯尔案例：运气的作用
The philosophical punch comes from the gap between justification and truth caused by epistemic luck. To analyse such a case, first restate it clearly, labelling each element: the initial evidence, the inference, the truth‑maker, and the point where luck intervenes.
哲学冲击力来自确证与真理之间由认知运气造成的隔阂。分析此类案例时，首先要清晰地重述案例，标注每个要素：初始证据、推论、真理制造者以及运气介入的节点。
Then test proposed solutions. Some say knowledge requires a causal connection between belief and fact; others demand that the justification not be defeated by any true proposition. Evaluate whether adding a ‘no false lemmas’ condition (the justification must not rely on any false belief) successfully rules out Gettier cases while preserving genuine knowledge.
然后检验所提出的解决方案。有人说知识要求信念与事实之间存在因果联系；另一些人要求确证不被任何真命题所击败。评估增加’无假引理’条件（确证不能依赖任何假信念）是否成功排除了盖梯尔案例而又保留了真正的知识。
A high‑level analysis will note that new counterexamples (like the fake barn case) challenge even refined definitions. This shows philosophy’s iterative nature.
高水平的分析会提到，新的反例（比如假谷仓案例）甚至挑战了经过改进的定义。这显示了哲学的迭代性质。
6. The Ship of Theseus: Identity over Time | 忒修斯之船：历时同一性
The Ship of Theseus is a metaphysical puzzle about persistence. Over many years, every plank of a ship is replaced, one by one. Is the resulting vessel still the same ship? If someone gathered all the old planks and reassembled them into a ship, which one is the original?
忒修斯之船是一个关于持存的形而上学难题。许多年里，船上的每一块木板都被逐一替换。最终的船还是原来那艘船吗？如果有人收集了所有旧木板并将它们重新组装成一艘船，哪一艘才是原来的？
This case tests theories of identity: the spatiotemporal continuity view, the psychological continuity view (for persons), and the mereological essentialist view that objects have their parts essentially. It also connects to debates about personal identity, such as Locke’s memory theory and the duplication problems raised by fission cases.
这个案例检验了同一性理论：时空连续性观点、心理连续性观点（对人格而言）以及认为物体必然具备其部分的整分本质主义观点。它也关联到人格同一性的争论，例如洛克的记忆理论以及由分裂案例引发的复制问题。
7. Using Cases to Develop Conceptual Analysis | 利用案例发展概念分析
Good philosophy often proceeds by proposing a definition, then stress‑testing it against cases. If a case produces a counter‑intuitive result, we must either revise the definition or explain away the intuition. This dialectical method lies at the heart of Pre‑U case analysis questions.
好的哲学常常通过提出一个定义，然后对照案例进行压力测试来推进。如果某个案例产生了反直觉的结果，我们要么修改定义，要么解释掉那个直觉。这种辩证法是 Pre‑U 案例分析问题的核心。
For instance, consider the concept of ‘free will’. A case where a person’s brain is controlled by a scientist seems to rob the person of freedom. Does this mean free will is incompatible with determinism? Cases help us isolate the necessary and sufficient conditions for the application of a concept.
例如，考虑’自由意志’概念。一个由科学家控制大脑的人似乎没有了自由。这是否意味着自由意志与决定论不相容？案例帮助我们分离出应用一个概念所需的充分必要条件。
8. Structuring a Case Analysis Essay | 构建案例分析论文结构
A successful Pre‑U response should open with a concise statement of the philosophical problem the case raises. Do not simply repeat the case; identify the abstract question behind it.
一篇成功的 Pre‑U 回答应该以简明陈述案例所引发的哲学问题开头。不要仅仅复述案例，要识别其背后的抽象问题。
Next, outline at least two contrasting positions, using the case as a touchstone. Supply arguments for each, making sure to reference specific features of the case that support or challenge a viewpoint. Use signposting language: ‘This element of the case suggests…’, ‘However, one might object that…’
接下来，以案例为试金石，概述至少两个相互对立的立场。为每种立场提供论证，务必援引案例中支持或挑战某个观点的具体特征。使用路标性语言：’案例的这一要素表明……’、’然而，有人可能反驳说……’
Conclude with a reasoned adjudication. Do you need to endorse one side fully? No, but you must show which considerations carry more weight and why, perhaps noting unresolved tensions.
以有理有据的裁决作为结论。你需要完全赞同某一方吗？不需要，但你必须表明哪些考量更有分量及其原因，或许也要指出尚未解决的张力。
9. Common Pitfalls and How to Avoid Them | 常见陷阱及其规避方法
One mistake is treating the case as a mere illustration rather than the engine of your argument. You must engage with the details. Another is failing to define your terms: if the question concerns knowledge, state early how you are using ‘justification’ or ‘truth’.
一个错误是把案例仅仅当作插图，而不是你论证的引擎。你必须紧扣细节。另一个错误是未能定义术语：如果问题围绕知识，尽早说明你如何理解’确证’或’真理’。
Avoid unexamined intuitions. Don’t just say ‘it is obvious that this is wrong’; explore why someone might hold the opposite intuition. Also, resist the temptation to list every theory you know; choose the most relevant and dig deep.
避免未经检视的直觉。不要只说’这显然是错误的’；要探究为什么某人可能持相反的直觉。此外，要克制罗列所有你知道的学说；选择最相关的并深入挖掘。
Finally, never leave an objection unanswered. If you raise a strong counter‑example, show how your position can accommodate it or why it is not fatal.
最后，永远不要让一个反驳没有回应。如果你提出一个强有力的反例，要展示你的立场如何容纳它，或为何它并非致命。
10. Worked Practice: Nozick’s Experience Machine | 练习案例：诺齐克的体验机器
Robert Nozick’s experience machine thought experiment asks: if you could plug into a machine that gives you any pleasurable experience you desire, with no awareness it is an illusion, would you? Most people say no, suggesting we value not just pleasure but also authenticity and contact with reality.
罗伯特·诺齐克的体验机器思想实验问道：如果你可以接入一台机器，让你体验任何你想要的愉悦，且毫不察觉这是幻觉，你会吗？多数人说不会，这暗示我们看重的不仅仅是愉悦，还有真实性和与现实的接触。
To analyse this, first articulate the challenge to hedonistic utilitarianism: pleasure cannot be the only intrinsic good if we care about how that pleasure is produced. Then consider replies: might the reluctance be irrational? Has the machine really captured all we value? Could a refined hedonism include the pleasure of genuine achievement?
要分析这个案例，首先阐明它对享乐功利主义的挑战：如果我们关心愉悦是如何产生的，那么愉悦就不能是唯一的内在善。然后考虑回应：这种不情愿会不会是非理性的？机器真的涵盖了我们珍视的一切吗？一种精致的享乐主义能否包含真实成就带来的愉悦？
Build your answer around the tension between our pre‑reflective reactions and the possibility of a systematic error in those reactions. Show awareness of the dialectical move: the machine forces the hedonist to expand their list of pleasures, but doing so risks making the theory trivial.
围绕我们反思前的反应与那些反应可能存在系统性错误之间的张力来构建答案。表明你意识到辩证的下一步：体验机器迫使享乐主义者扩展愉悦的清单，但这样做有使理论变得空洞的风险。
11. Applying Case Analysis to Metaphysics of Mind | 将案例分析应用于心灵形而上学
Cases like ‘What Mary Didn’t Know’ (Jackson’s knowledge argument against physicalism) and the ‘Chinese Room’ (Searle’s argument against strong AI) demand similar analytical rigour. In Mary’s case, a scientist who knows all physical facts about colour experiences colour for the first time upon leaving a black‑and‑white room. Does she learn something new? If so, physicalism is false.
像’玛丽不知道的事’（杰克逊反对物理主义的知识论证）和’中文屋’（塞尔反对强人工智能的论证）这样的案例要求类似的分析严谨性。在玛丽案例中，一位知道一切关于颜色的物理事实的科学家，在离开黑白房间后第一次体验到颜色。她学到新东西了吗？如果是，物理主义为假。
To analyse, isolate the premise: if physicalism is true, complete physical knowledge is all knowledge. Mary has complete physical knowledge but seems to gain new knowledge (what it is like to see red). Evaluate whether the ‘ability hypothesis’ (she gains only abilities, not facts) or the ‘phenomenal concept strategy’ successfully defuse the argument.
分析时要分离前提：如果物理主义为真，那么完全的物理知识就是全部知识。玛丽拥有完全的物理知识，但似乎获得了新知识（看见红色的感受质性）。评估’能力假说’（她只获得了能力，而非事实知识）或’现象概念策略’是否成功消解了论证。
12. Exam‑Ready Strategy and Final Tips | 考试策略与最终建议
In the exam, read the case twice. Annotate it with the philosophical issues you see: circle crucial words like ‘only’, ‘just’, or ‘same’. Spend a few minutes outlining your response before you write. Time management is crucial; each case analysis should have a clear, limited scope rather than trying to cover everything.
考试中，阅读案例两遍。用你看到的哲学问题加以批注：圈出’仅仅’、’恰好’、’同一’等关键词语。动笔前花几分钟列出回答大纲。时间管理至关重要；每个案例分析应该有清晰、有限的讨论范围，而不是试图涵盖一切。
Remember that the mark scheme rewards critical evaluation, structured reasoning, and precise use of philosophical vocabulary. Use words like ‘entails’, ‘sufficient condition’, ‘intuition pump’, and ‘begs the question’ accurately. Above all, show that you are thinking philosophically, not just reporting what philosophers have said.
记住，评分标准奖励批判性评估、结构化的推理和准确使用哲学术语。准确使用诸如’蕴含’、’充分条件’、’直觉泵’和’乞题’等词语。最重要的是，要展现你是在进行哲学思考，而不仅仅是报告哲学家说过的话。
Practise with a wide range of cases: from Plato’s Ring of Gyges to Parfit’s teletransporter. The skill of case analysis, once internalised, becomes a portable toolkit you can deploy in any area of the syllabus.
用各种案例来练习：从柏拉图的裘格斯戒指到帕菲特的远距传送器。案例分析技能一旦内化，就会成为一个可随身携带的工具箱，你能在考纲的任何领域加以运用。
