📚 Case Study Practice | 案例分析实战演练
Welcome to your practical guide for tackling case studies in Edexcel Year 10 Philosophy. Case studies are not just stories – they are carefully constructed thought experiments that test your ability to apply philosophical theories, identify assumptions, and build reasoned arguments. In this article we will walk through several classic examples, step by step, to sharpen your analytical skills and prepare you for exam success.
欢迎来到Edexcel十年级哲学案例分析实战指南。案例不只是故事——它们是精心构建的思想实验，用来检验你应用哲学理论、识别假设和构建理性论证的能力。本文将带领你逐步分析几个经典案例，磨砺你的分析技能，为考试成功做好准备。
1. Why Case Studies Matter in Philosophy | 为什么案例分析在哲学中重要
Philosophy is not simply about memorising names and quotes. It is a method of thinking. Case studies force you to step into a real or hypothetical situation and ask: what would a utilitarian say? How would a deontologist respond? What would a virtue ethicist praise or criticise? By working through scenarios, you learn to connect abstract theory with concrete judgement, which is exactly what examiners look for.
哲学不只是记住人名和语录，它是一种思维方式。案例分析迫使你走进一个真实或假设的情境，然后追问：功利主义者会怎么说？义务论者会如何回应？德性伦理学家会赞扬还是批评什么？通过分析情境，你学会了把抽象理论与具体判断连接起来，而这正是考官所看重的。
Additionally, case studies reveal unexamined intuitions. When you are faced with the Trolley Problem, your immediate reaction might be “of course I would pull the lever,” but digging deeper exposes tensions in your moral reasoning. The skill lies in clarifying why you hold that intuition and whether it stands up to philosophical scrutiny.
此外，案例能揭示未经审视的直觉。当你面对电车难题时，第一反应可能是“我当然会拉动拉杆”，但深入挖掘会暴露你道德推理中的矛盾。技巧在于阐明你为什么会有这种直觉，以及它能否经得起哲学推敲。
2. Key Steps in Analysing a Case Study | 分析案例的关键步骤
Every case study can be broken down using a simple framework: identify the moral or philosophical dilemma, list the relevant facts, isolate the central philosophical question, apply at least two contrasting theories, and then weigh the strengths and weaknesses of each response. Start by reading the scenario twice – first for the big picture, second for details that carry philosophical weight.
每个案例分析都可使用一个简单框架来拆解：识别道德或哲学困境，列出相关事实，提炼核心哲学问题，应用至少两种对立的理论，然后权衡每一种回应的优点与不足。先读两遍场景——第一遍抓住整体，第二遍捕捉具有哲学分量的细节。
Next, state the main question clearly. For example, in the Trolley Problem the question is: “Is it morally permissible to sacrifice one innocent person to save five?” Once the question is explicit, you can map theories onto it. Use a table to compare responses if it helps, but always follow up with evaluative commentary. Remember that exam credit comes from reasoned analysis, not from simply describing a theory.
接下来，清晰地陈述主要问题。例如在电车难题中，问题是：“牺牲一个无辜的人去救五个人在道德上允许吗？”问题一旦明确，你就可以把理论映射上去。如果有助于对比，可以用表格罗列不同回应，但务必紧随其后进行评价性评论。记住，考试分数来自理性的分析，而不是单纯描述某个理论。
| Step | Action |
|---|---|
| 1 | Identify dilemma and stakeholders |
| 2 | Isolate the central philosophical question |
| 3 | Apply Theory A (e.g. Utilitarianism) |
| 4 | Apply Theory B (e.g. Kantian ethics) |
| 5 | Evaluate strengths, weaknesses and tensions |
| 6 | Offer a justified conclusion |
3. Ethical Case Study: The Trolley Problem | 伦理案例：电车难题
A runaway trolley is heading down a track where five people are tied and unable to move. You are standing next to a lever. If you pull the lever, the trolley will switch to a side track, but there is one person tied on that side track. Do you pull the lever? The scenario was devised by Philippa Foot to explore the ethics of action versus inaction and the doctrine of double effect.
一辆失控的电车正冲向五个人被绑着的轨道，他们无法动弹。你站在一根拉杆旁边。如果你拉动拉杆，电车会转向一条岔道，但岔道上绑着一个人。你拉不拉拉杆？这个场景由菲利帕·富特设计，用来探讨行动与不行动的伦理，以及双重效果学说。
In a variation, the only way to stop the trolley is to push a large man off a bridge into its path. Most people who would pull the lever in the original case refuse to push the man. This divergence challenges simple utilitarian calculations and introduces the relevance of intention, physical involvement, and rights.
在一个变体中，唯一能阻止电车的方法是把一个大个子从桥上推下去，让他掉到轨道上。多数在原版情境中会拉拉杆的人拒绝把那个人推下去。这种分歧挑战了简单的功利计算，并引入了意图、身体介入以及权利的相关性。
4. Deconstructing the Trolley Problem | 解构电车难题
A utilitarian like Jeremy Bentham would argue that you must pull the lever because saving five lives at the cost of one maximises overall happiness. The arithmetic is simple: 5 lives > 1 life. However, the utilitarian must also consider secondary effects – if people knew that bystanders could sacrifice one to save many, would it create a climate of fear that reduces overall utility? This nuance shows that utilitarianism is not always crude head-counting.
像杰里米·边沁这样的功利主义者会论证你必须拉拉杆，因为用一条生命代价拯救五条生命最大化了总体幸福。算术很简单：5条命 > 1条命。然而功利主义者还必须考虑次级效应——如果人们知道旁观者可以牺牲一人去救很多人，会不会制造出恐惧氛围从而降低总体功利？这一细微差别表明功利主义并不总是粗陋的数人头。
By contrast, a Kantian would insist that you must never use a person merely as a means to an end. Pulling the lever treats the single person on the side track as a tool to save the five, which violates the categorical imperative. For Kant, the right action is not to interfere, even if the consequence is more deaths. The moral worth resides in the motive of acting from duty, not in the outcome.
相比之下，康德主义者会坚称你绝不能仅仅把人当作达到目的的手段。拉动拉杆就是把岔道上的那个人当作拯救五人的工具，这违反了绝对命令。对康德而言，正确的做法是不介入，哪怕后果是更多人死亡。道德价值在于从义务出发的行动动机，而非结果。
5. Epistemology Case Study: The Gettier Problem | 知识论案例：盖梯尔问题
In 1963, Edmund Gettier published a short paper that shook the traditional definition of knowledge as justified true belief (JTB). Imagine Smith has strong evidence that Jones will get a job and also that Jones has ten coins in his pocket. Smith concludes: “The man who will get the job has ten coins in his pocket.” Unknown to Smith, he himself will get the job and he also happens to have ten coins in his pocket. Smith’s belief is justified and true, yet it seems wrong to call it knowledge.
1963年，埃德蒙·盖梯尔发表了一篇短文，动摇了把知识定义为得到辩护的真信念（JTB）的传统。设想史密斯有充分证据表明琼斯会得到那份工作，并且琼斯口袋里有十枚硬币。史密斯推断：“那个将得到工作的人口袋里有十枚硬币。”史密斯不知道的是，他自己将得到工作，而且他口袋里也碰巧有十枚硬币。史密斯的信念既得到辩护又为真，但把它称为知识似乎不对劲。
This case demonstrates that justified true belief can be accidentally true, or true for the wrong reasons. Since the 1960s, epistemologists have debated how to fix the definition – by adding a “no false lemmas” condition, or by requiring a causal connection between the fact and the belief, or via reliabilism. For your Year 10 work, you do not need to master every response, but you must show that you understand the problem JTB faces.
这个案例表明，得到辩护的真信念可能只是出于偶然为真，或是因错误理由为真。自20世纪60年代以来，知识论学者一直在争论如何修补这个定义——通过增加“无错误引理”条件，或者要求事实与信念之间存在因果联系，或是采用可靠主义。对于十年级的学习，你不需要掌握每一种回应，但必须表现出你理解 JTB 所面临的问题。
6. Breaking Down the Gettier Problem | 解析盖梯尔问题
To analyse a Gettier-style case, begin by separating the belief, the justification, and the truth. In Smith’s case: belief = the job-getter has ten coins; justification = evidence about Jones; truth = Smith gets the job and has ten coins. The truth is disconnected from the justification. This gap is what makes knowledge fall short – the justification points to one source of truth while the actual truth arises from another.
要分析盖梯尔式案例，先把信念、辩护和真值分开。在史密斯的例子中：信念 = 得到工作的人有十枚硬币；辩护 = 关于琼斯的证据；真值 = 史密斯得到工作并有十枚硬币。真值与辩护是脱节的。这一断裂正是知识未能达致的原因——辩护指向某一真相来源，而实际真相却来自另一来源。
You can strengthen your analysis by varying the case. What if Smith had no evidence at all? Then the belief would lack justification. What if the belief were false? Then it obviously would not be knowledge. Gettier cases are so powerful because they tick all three boxes yet intuition still rebels. A good exam answer will articulate exactly why this misfit troubles the JTB account and will sketch one alternative approach, such as adding a reliability condition.
你可以通过变换案例来加强分析。要是史密斯根本没有证据呢？那么信念就缺乏辩护。要是信念是假的呢？那显然就不是知识。盖梯尔案例之所以强大，是因为它们三个框框都打了勾，而直觉依然抗拒。一份好的考试答案会清晰说明为何这种错位令 JTB 说法陷入困境，并简要勾勒一种替代进路，比如增加可靠性条件。
7. Metaphysics Case Study: The Ship of Theseus | 形而上学案例：忒修斯之船
According to an ancient puzzle, the Athenians preserved Theseus’s ship by gradually replacing every decaying plank and part. After some years, none of the original material remains. Is the restored ship still the Ship of Theseus? If not, when did it stop being the same ship? To complicate matters, imagine someone collects all the discarded original planks and reassembles them into a second ship. Which, if either, is the real Ship of Theseus?
根据一个古老谜题，雅典人通过逐一更换腐朽的木板和部件来保存忒修斯之船。若干年后，最初的原材料一块不剩。修复后的船还是忒修斯之船吗？如果不是，它在何时不再是同一艘船？更复杂的是，设想有人收集了所有被丢弃的原装木板，重新组装出第二艘船。两艘船中，哪艘才是真正的忒修斯之船呢？
This thought experiment probes the nature of identity over time – what philosophers call “persistence conditions.” Is identity tied to the continuity of material substance, to structural form, or to a narrative history? Different theories of personal identity face the same challenge: are you the same person you were at age five, given that almost every cell has been replaced?
这个思想实验探究的是同一性在时间中的本质——哲学家称之为“持存条件”。同一性是与物质实体的连续性绑定的，还是与结构形式，或是与叙述历史相连？不同的人格同一性理论也面临同样的挑战：既然几乎所有的细胞都被替换过，你还是五岁时的那个你吗？
8. Examining Identity and Change | 探究同一性与变化
One approach to the Ship of Theseus is to adopt a spatiotemporal continuity view: the ship on display is the original because it traces a continuous path through space and time, with gradual replacement that preserves form and function. The bundle theory of material objects would support this by claiming an object is merely a bundle of properties, and the property-bundle persists even as individual components change.
处理忒修斯之船的一种进路是采取时空连续性观点：陈列着的那艘船是原装的，因为它溯循着一条连续的时空路径，以渐进式替换保存了形式和功能。关于物质对象的束理论会支持这一看法，主张物体无非是属性的集合束，即便个别组件变化，属性束依然持存。
Alternatively, the mereological essentialist argues that an object’s parts are essential to its identity; change any part, and you have a different object. This view struggles to explain everyday objects like cars or even human bodies. A compromise position might say that for artefacts, functional continuity is what matters, but for living organisms, biological continuity counts most. When writing your analysis, map these theories onto the case explicitly and show how they lead to different conclusions.
另一种观点是部分论本质主义，认为一个物体的各个部分对其同一性至关重要；更换任何部分，就是另一个物体了。这一观点难以解释日常物品如汽车甚至人体。折中立场可能会说，对于人造物，功能连续性才是关键，而对于生命有机体，生物连续性最为要紧。在你撰写分析时，务必明确地将这些理论映射到案例上，展示它们如何导出不同结论。
9. Comparing Philosophical Responses | 比较哲学回应
When comparing responses to a case study, avoid simply listing theories side by side. Instead, create a dialogue. For the Ship of Theseus, you might write: “Whereas the continuity theorist focuses on the seamless history of the display ship, the reassembly advocate insists the original matter carries the identity. The first view implies identity is a social and functional concept; the second view treats identity as a brute physical fact.” This “whereas…however…” structure demonstrates synthesis.
在比较案例的不同回应时，不要仅仅把理论并排罗列。而是要创造对话。针对忒修斯之船，你可以这样写：“连续性论者侧重于陈列船那无间断的历史，而重组派坚持原始物料承载着同一性。前一种观点暗示同一性是一个社会和功能概念；后一种观点则把同一性视作原始物理事实。” 这种“而……然而……”的结构展现了综合能力。
Another powerful technique is to apply the same theory to two variations of a case. Take the Trolley Problem and its footbridge variant. A Kantian can consistently say “do not pull and do not push” because the maxim of using a person as a mere means remains the same. A utilitarian might struggle to explain why pushing feels worse if the arithmetic is identical. Highlighting this internal tension within a theory shows higher-order evaluation, which is rewarded in top mark bands.
另一个有力技巧是把同一套理论应用到案例的两个变体上。以电车难题及其天桥变体为例。康德主义者可以始终如一地说“既不要拉也不要推”，因为把人仅仅当作手段这一准则是不变的。功利主义者或许难以解释，如果算式相同，为什么推人感觉更糟。突显理论内部的这种张力就展示了高阶评价，这在高分档中会得到奖赏。
10. Crafting Your Own Argument | 构建你自己的论证
After presenting the theories, you must take a stand. A strong conclusion does not need to be absolute – you can hold a provisional position while acknowledging its limits. For instance: “I conclude that pulling the lever is morally permissible because the distinction between doing and allowing is morally shallow in this context, yet I concede that pushing the man introduces an element of direct assault that changes the moral character of the act.”
在呈现了各种理论之后，你必须表明立场。一个有力的结论不必是非此即彼的——你可以持有一个临时立场，同时承认其局限。例如：“我的结论是拉动拉杆在道德上允许，因为在这种语境下做与允许发生的区分在道德上是肤浅的，但我承认推人引入了直接攻击的要素，这改变了行为的道德性质。”
When constructing your argument, use clear signposting: “My first reason is…”, “A possible objection is…”, “I can reply that…”. This not only makes your reasoning easy to follow but also mirrors the structure of philosophical writing expected at GCSE. Always link back to the specific details of the case study – don’t float off into abstract theory. Concrete engagement with the scenario is key.
构建论证时，使用清晰的路标词：“我的第一个理由是……”、“可能的反对意见是……”、“我可以回应说……”。这不仅让你的推理易于跟上，也吻合 GCSE 期望的哲学写作结构。永远要回连案例的具体细节——不要飘到纯抽象理论上去。与情境的具体互动是关键。
11. Common Pitfalls to Avoid | 常见误区避免
One frequent mistake is “story-telling” – simply retelling the case study without analysis. Assume your reader knows the scenario. Another is “theory dumping” – dropping in long descriptions of Kant or Bentham without applying them to the case. Marks are awarded for using the theory to illuminate the dilemma, not for reproducing textbook paragraphs. Stay focused on the philosophical question.
一个常见错误是“讲故事”——只是复述案例而没有分析。要假定读者已经知道情境。另一个误区是“理论堆砌”——丢进一大段对康德或边沁的描述，却不应用到案例中。分数是奖给用理论来照亮困境的，而不是复制教科书段落。始终紧扣哲学问题。
Avoid one-sided analysis. Even if you strongly favour utilitarianism, explore the strongest objection against it. This shows critical engagement. Also, be careful with language: use “argues” rather than “believes”, “entails” rather than “means”, and “justified” rather than “right”. Precision in terminology signals philosophical maturity. Finally, don’t forget to consider whether the case study has any unrealistic features that limit its usefulness – a quick evaluative point can lift a mid-level answer to a high one.
避免一边倒的分析。即便你强烈倾向于功利主义，也要探讨针对它的最强反驳。这体现了批判性参与。还有，注意用词：使用“论证”而非“相信”，用“蕴含”而非“意味着”，用“得到辩护”而非“正确”。术语精确标志着哲学成熟度。最后，别忘了考虑案例是否有任何不切实际的特征限制了它的效用——一个简短的评估性要点就能把中等答案提升到高分段。
12. Putting It All Together | 综合运用
Let us now model a concise analysis using the framework. Picture a new case: a doctor has five patients needing different organ transplants, and a healthy young visitor walks into the hospital. Should the doctor sacrifice the one to save the five? The utilitarian calculation seems to recommend killing the visitor, but this conclusion strikes almost everyone as monstrous. A Kantian explains why: the visitor has not consented and using him as a mere means violates a perfect duty.
现在让我们用框架示范一份简洁的分析。设想一个新案例：一位医生有五位病人需要不同的器官移植，而一个健康的年轻访客走进了医院。医生是否应该牺牲这一个去救五个人？功利计算似乎建议杀死访客，但这个结论在几乎所有人看来都是骇人听闻的。康德主义者解释了为什么：访客没有同意，把他仅仅当作手段侵犯了一项完全义务。
Your analysis could then explore a rule-utilitarian response: if doctors were allowed to kill patients in such cases, trust in medicine would collapse, so a rule against killing actually maximises utility in the long run. Notice how this move brings us back to the same recommendation but for different reasons. You could then conclude that while act-utilitarianism appears to fail, rule-utilitarianism aligns with deontological intuitions, showing that the gap between theories can sometimes be bridged.
你的分析可以接着探讨规则功利主义的回应：如果医生允许在这种情况下杀死病人，人们对医疗的信任就会崩塌，因此禁止杀人的规则在长期中实际上最大化了功利。注意这一步是如何以不同理由回到了相同的建议。然后你可以得出结论：尽管行为功利主义似乎站不住脚，但规则功利主义与义务论直觉保持一致，说明理论之间的鸿沟有时也能弥合。
Practice with as many case studies as you can. Start with the classics – the ones in this article – then apply the same method to unfamiliar ones provided by your teacher. The more you practise, the more natural it becomes to spot the philosophical crux, structure your analysis, and produce the kind of well-argued evaluation that stands out in Edexcel assessments. Philosophy is a skill, and case study analysis is your training ground.
尽可能多地用案例来练习。从经典案例起步——本文中的那些——然后把同样的方法应用到老师提供的不熟悉的案例上。练得越多，你就越能自然地抓住哲学症结、组织分析结构，并写出那种在 Edexcel 评估中脱颖而出的论证充分的评价。哲学是一门技能，而案例分析就是你的训练场。
