📚 Case Study Practical Training | 案例分析实战演练

Mastering case study questions in IGCSE Edexcel Philosophy is not about memorising theories, but about learning to think like a philosopher. This guide provides a step-by-step approach to breaking down real-world scenarios, applying ethical frameworks, and constructing well-evaluated answers that will earn top marks.

在IGCSE Edexcel 哲学中掌握案例分析题，靠的不是死记硬背理论，而是学会像哲学家一样思考。本指南将一步步带你拆解真实情境、应用伦理论框架，并构建出能拿高分的有理有据的答案。

1. Understanding the Assessment Objectives | 理解评估目标

IGCSE Edexcel Philosophy papers assess three key skills: knowledge and understanding of theories (AO1), application of those theories to issues and cases (AO2), and analysis and evaluation to form a justified conclusion (AO3). In a case study question, all three AOs are tested together, so your answer must show you can describe a theory, apply it accurately to the details of the case, and then weigh up its strengths and weaknesses before reaching a reasoned verdict.

IGCSE Edexcel 哲学试卷考查三项核心技能：理论与知识的理解（AO1）、将理论应用于议题和案例（AO2），以及分析评估并形成有依据的结论（AO3）。案例分析题将这三项技能融合考查，因此你的答案必须既描述理论，又能准确运用到案例细节中，并权衡其优缺点，最后得出经过推理的判断。

2. Deconstructing the Case: Identifying the Core Ethical Dilemma | 拆解案例：识别核心伦理困境

Before applying any ethical theory, read the case twice. First, underline the key facts: who is involved, what action is being considered, and what consequences are at stake. Second, identify the moral dilemma by asking: ‘What makes this situation ethically difficult?’ Often the dilemma is a clash between two values – for example, individual freedom versus the common good, or compassion versus a strict moral rule.

在应用任何伦理理论之前，请把案例读两遍。第一遍，划出关键事实：涉及哪些人、正在考虑采取什么行动、有什么后果。第二遍，通过问自己’是什么让这种情况在伦理上变得困难？’来识别道德困境。这种困境通常是两种价值观的冲突——例如，个人自由与共同利益，或同情心与严格的道德准则。

Example dilemma: A driverless car must choose between hitting a group of pedestrians or swerving and killing the passenger. Key clash: saving more lives versus protecting an innocent individual who has not consented to sacrifice.
示例困境：一辆无人驾驶汽车必须在撞上一群行人或转向让乘客丧生之间做出选择。核心冲突：救更多人还是保护一个没有同意牺牲的无辜个人。

3. Applying Utilitarianism | 应用功利主义

Utilitarianism judges an action by its consequences: the right act is the one that produces the greatest happiness for the greatest number. When applying it to a case, first list all people (or sentient beings) affected. Then estimate the pleasure and pain each would experience from the various possible actions. Use Bentham’s hedonic calculus if the case allows – considering intensity, duration, certainty, etc. Finally, calculate which option maximises net happiness. Remember to mention the theory’s emphasis on impartiality; everyone’s happiness counts equally.

功利主义根据后果来判断行为：正确的行为是为最大多数人带来最大幸福的行为。应用到案例时，首先列出所有受影响的人（或有感知力的生命）。然后估算每种可能行为给各方带来的快乐与痛苦。如案例允许，可运用边沁的幸福计算法——考虑强度、持续时间、确定性等。最后，算出哪种选择能使净幸福最大化。记住要提到该理论的公正性要求：每个人的幸福都同等重要。

Hedonic Calculus factors: Intensity, Duration, Certainty, Propinquity, Fecundity, Purity, Extent

幸福计算因素：强度、持续时间、确定性、临近性、继生性、纯度、范围

A common mistake is to only count the most obvious consequences. A strong answer will also consider the long-term ripple effects on trust, social stability, and the psychological impact on decision-makers.

一个常见错误是只计算最明显的后果。一份优秀的答案还会考虑到对信任、社会稳定以及决策者心理影响的长期涟漪效应。

4. Applying Kantian Ethics | 应用康德伦理学

Kant’s deontological approach focuses on duty and the categorical imperative, not consequences. To apply it, first formulate the maxim (the principle behind the proposed action). Then universalise it: ‘Can I rationally will that everyone in a similar situation act on this maxim?’ If universalising leads to a contradiction in conception or in the will, the act is morally forbidden. Next, test whether the action treats any person merely as a means to an end, rather than as an end in themselves. Respect for persons is absolute.

康德的义务论方法关注责任和绝对命令，而非后果。应用时，首先构建出准则（所提议行动背后的原则）。然后将其普遍化：’我能否理性地愿意让所有人在类似情况下都按照这个准则行事？’如果普遍化导致构想上的矛盾或意愿上的矛盾，该行为在道德上就是被禁止的。接着，检验该行为是否将任何人仅仅当作实现目的的手段，而不是当作目的本身。对人的尊重是绝对的。

If a business is considering lying to a customer to secure a deal, the maxim would be: ‘It is acceptable to make false promises for financial gain.’ Universalising this would undermine the institution of promising itself, creating a contradiction in conception. The act is wrong regardless of any beneficial outcome.
如果一家公司考虑对客户说谎以确保交易，准则就是：’为了经济利益做出虚假承诺是可接受的。’将其普遍化会破坏承诺制度本身，造成构想上的矛盾。无论会有何种有利结果，这种行为都是错误的。

Kantian ethics often clashes with deeply intuitive compassionate choices, so an evaluative answer should discuss whether the rigidity of duty can accommodate human complexity.

康德伦理学常与深植于直觉的同情心选择相冲突，因此评估性答案应当讨论：责任的严格性是否能够容纳人类的复杂性。

5. Applying Situation Ethics | 应用境遇伦理学

Situation Ethics, proposed by Joseph Fletcher, holds that the only absolute rule is agape (selfless, unconditional love). In any case, you should ask: ‘What is the most loving thing to do in this specific situation?’ All other moral rules, even ‘do not kill’ or ‘do not lie,’ can be set aside if love demands it. When applying this theory, first identify how each possible course of action expresses practical care and concern for the persons involved. Then justify the choice by explaining why it embodies agape, considering the unique circumstances.

由约瑟夫·弗莱彻提出的境遇伦理学认为，唯一绝对的准则就是圣爱（无私、无条件的爱）。在任何案例中，你都应该问：’在这种特定情况下，最具有爱心的做法是什么？’所有其他道德规则，哪怕是’不可杀人’或’不可说谎’，如果爱要求打破，都可以搁置。应用这一理论时，首先要识别每种可能的行动方案如何体现对相关者的实际关怀。然后通过解释为何该选择体现了圣爱，并结合独特的情境来论证。

Be careful not to reduce Situation Ethics to simple relativism. It still uses the community’s moral wisdom as a starting point; it simply refuses to treat rules as idols. In an exam, always link your reasoning explicitly to the concept of agape.

注意不要把境遇伦理学简化为简单的相对主义。它仍然以群体的道德智慧为出发点，只是拒绝把规则当作偶像。在考试中，一定要将你的推理明确地与圣爱的概念联系起来。

6. Considering Religious Perspectives | 考虑宗教视角

IGCSE Edexcel often includes religious ethical perspectives, especially from Christianity. You may need to apply teachings from the Bible, Natural Law theory, or the sanctity of life principle. For example, in a case about euthanasia, the sanctity of life view holds that life is a gift from God and only God has the right to take it away. This leads to an absolute prohibition on intentional killing, irrespective of compassion. Alternatively, some Christian thinkers use a more flexible personalist approach, prioritising the well-being of the person over biological life at all costs.

IGCSE Edexcel 常包含宗教伦理视角，尤其是基督教视角。你可能需要应用圣经教义、自然法理论或生命神圣性原则。例如，在一个关于安乐死的案例中，生命神圣性观点认为生命是上帝的礼物，只有上帝有权取走。这导致无论出于何种怜悯之心，都绝对禁止故意杀人。另外，一些基督教思想家采用更灵活的人格主义进路，优先考虑人的完整福祉，而不惜一切代价维持生物学生命。

When using religious perspectives, always support claims with specific evidence: a quotation from Proverbs or the teaching of Jesus on love, or Aquinas’s primary precepts. Never treat a religious view as monolithic – there are often diverse interpretations within the tradition.

在运用宗教视角时，始终提供具体证据来支撑观点：比如《箴言》的话或耶稣关于爱的教导，或阿奎那的基本诫命。不要把宗教观点看作铁板一块——传统内部往往存在着多样的诠释。

7. Analysis and Evaluation: Comparing Theories | 分析与评估：比较不同理论

The heart of a top-band answer is comparative evaluation. After applying two or three theories to the case, you should compare them by noting where they agree and where they diverge. Ask critical questions: Which theory handles the particular context more sensitively? Does utilitarianism’s calculation ignore individual rights? Does Kant’s formalism produce a result that contradicts moral common sense? Which approach is most consistent, or most adaptable to real life?

高分答案的核心在于比较性评估。在将两三种理论应用到案例后，你应当比较它们的一致与分歧之处。提出批判性问题：哪种理论对这个具体情境的处理更为细腻？功利主义的计算是否忽略了个体权利？康德的形式主义是否产生了与道德常识相矛盾的结果？哪种方法最一致，或最适应现实生活？

Theory	Strengths in this case	Weaknesses in this case
Utilitarianism	Focuses on overall welfare; flexible	May justify sacrificing an innocent minority
Kantian Ethics	Protects individual dignity and rights	Too rigid; ignores consequences and emotions
Situation Ethics	Personalised and compassionate	Too subjective; can be unpredictable

Your conclusion should not be a random favourite, but a justified preference with reasons why one theory’s insights outweigh the others in the specific circumstances. Use phrases like ‘Although Utilitarianism appears more practical, it fails to account for… therefore, the Kantian respect for persons provides a stronger ethical framework in this instance.’

你的结论不应是随意的偏好，而是有理由的、经过论证的倾向，说明在特定情境下为什么某一理论的洞见胜过其他。使用诸如’虽然功利主义看起来更实用，但它未能考虑到……因此，康德对人的尊重在此例中提供了更强的伦理框架’这样的表述。

8. Constructing a Structured Answer | 构建结构化答案

A clear structure makes your reasoning easy to follow. Follow this four-paragraph PEEL model (Point, Evidence, Explain, Link) within each section, and an overall introduction-contrast-conclusion shape:

Paragraph 1 (Introduction): Define the ethical dilemma succinctly. State which theories you will apply.
Paragraph 2 (Theory 1): Apply the first theory thoroughly to the case details, showing how it leads to a specific moral judgement. Evaluate its strengths and limitations in this case.
Paragraph 3 (Theory 2): Repeat for a contrasting theory, again with application and embedded evaluation.
Paragraph 4 (Conclusion): Compare the two approaches, showing why one offers a more convincing resolution. Reach a clear, justified final judgement.

一份清晰的结构能让你的推理易于理解。在每个部分内遵循四段式的PEEL模型（观点、证据、解释、联系），并采用总-对比-总的形式：

第1段（引言）：简洁地定义伦理困境。说明你将应用哪些理论。
第2段（理论1）：将第一种理论充分运用于案例细节，说明它如何导向一个特定的道德判断。评估它在此案例中的优势与局限。
第3段（理论2）：对一种对比理论重复上述步骤，同样包含应用和嵌入评估。
第4段（结论）：比较两种方法，说明为什么其中一种提供了更有说服力的解决方案。达成清晰、经过论证的最终判断。

9. Case Practice: Euthanasia | 案例实战：安乐死

Sample case: ‘Daniel, aged 38, has a terminal illness and is in constant, unbearable pain with no hope of recovery. He repeatedly asks his doctor to prescribe a lethal dose of medication. His family is divided: his spouse supports his wish to die with dignity, while his parents argue that life must be preserved at all costs. The doctor faces an ethical dilemma.’

案例： “38岁的丹尼尔患有绝症，持续承受无法忍受的痛苦且没有康复希望。他反复要求医生开具致死剂量的药物。他的家人意见分歧：他的配偶支持他尊严死去的愿望，而他的父母则认为必须不惜一切代价维持生命。医生面临道德困境。”

Using a utilitarian approach, one would consider the net happiness: Daniel’s suffering is immense and certain; his spouse’s grief is balanced by respecting his autonomy; his parents will grieve but may eventually find peace. The doctor’s action might also save medical resources for others. A hedonic calculation might well permit assisted dying. However, the evaluation must consider the slippery slope risk: could legalising it erode trust in doctors and lead to pressure on the vulnerable?

使用功利主义方法，将考量净幸福：丹尼尔的痛苦巨大且确定；配偶的悲伤因尊重他的自主而得以平衡；父母会悲痛但可能最终释怀。医生的行为还可能为他人腾出医疗资源。幸福计算很可能会允许协助死亡。然而，评估时必须考虑滑坡风险：合法化是否会削弱对医生的信任，并导致对弱势群体的压力？

A Kantian would focus on the maxim: ‘A doctor may end a suffering patient’s life when requested.’ Can this be universalised? Some argue it contradicts the duty to preserve life, treating the patient as a means to relieve family burden, violating the categorical imperative. Yet a Kantian might also argue that respecting Daniel’s rational autonomy to decide his own fate treats him as an end in himself. A strong answer would acknowledge this tension.

康德主义者会关注准则：“医生可以应请求结束受苦病人的生命。”这能普遍化吗？一些人认为这与保存生命的义务相矛盾，把病人当作缓解家庭负担的手段，违反了绝对命令。然而，康德主义者也可能争辩说，尊重丹尼尔对自己命运的理性自主，正是将他视为目的本身。优秀的答案会承认这种张力。

10. Case Practice: Animal Testing | 案例实战：动物实验

Sample case: ‘A research laboratory is developing a vaccine for a deadly human disease. The final stage requires testing on 50 monkeys, causing them pain and death, but saving potentially millions of human lives. An animal rights group is campaigning to shut it down. You advise the ethics committee.’

案例： “一家研究实验室正在研发一种可致命人类疾病的疫苗。最后阶段需要用50只猴子进行测试，这将导致它们痛苦和死亡，但可能拯救数百万人的生命。一个动物权利组织正在请愿关闭该实验室。你为伦理委员会提供建议。”

An act utilitarian would likely support the testing, because the vast human benefit outweighs the animal suffering, especially if the pain is minimised. Peter Singer’s preference utilitarianism, however, forces us to count the interests of sentient animals equally. If a monkey’s interest in avoiding suffering is no less than a human’s, the calculation becomes much closer. A strong examination answer must note that the utilitarian frame does not grant intrinsic dignity to humans or animals, only the ability to suffer.

行为功利主义者很可能支持测试，因为巨大的人类收益超过了动物的痛苦，尤其是在痛苦被降至最低的情况下。然而，彼得·辛格的偏好功利主义要求我们平等地考虑有感知力动物的利益。如果一只猴子避免痛苦的利益并不比人类少，这种计算就会变得非常接近。一份出色的考试答案必须指出，功利主义框架并不赋予人类或动物内在的尊严，只看重感知痛苦的能力。

Kantian ethics, with its focus on rational beings, traditionally excludes non-human animals from direct moral standing. Animals are not ends in themselves, but they can be indirect objects of our duties (e.g., we should not be cruel to animals because it dulls our sympathy for humans). A modern Kantian might challenge this, but for IGCSE, focus on the categorical imperative and the limited duties towards animals. A religious perspective might point to stewardship: humans have dominion over animals but must avoid unnecessary cruelty.

康德伦理学关注理性存在者，传统上不赋予非人类动物直接的道德地位。动物不是目的本身，但它们可以是我们义务的间接对象（例如，我们不应虐待动物，因为这会钝化我们对人类的同情心）。现代康德主义者可能会挑战这一点，但对于IGCSE，要聚焦于绝对命令和对动物的有限义务。宗教视角可能指向管家职分：人类拥有管理动物的权柄，但必须避免不必要的残忍。

11. Common Mistakes and How to Avoid Them | 常见错误及避免方法

Even well-prepared students lose marks through avoidable errors. The most frequent is ‘theory dumping’ – describing a theory in full without linking it to the case details. Every time you mention a concept, ask: ‘How does this specifically apply to the person or action in the case?’ Another trap is writing only descriptively without evaluation. Use evaluative phrases like ‘this is a weakness because…’ or ‘in practice, this may be difficult because…’ Avoid also the unbalanced answer that presents only one view. Even if you strongly agree, show you understand alternative positions.

即便准备充分的学生也会因可避免的错误而失分。最常见的是“理论倾倒”——完整描述理论却不与案例细节相联系。每次提到一个概念时，都要问自己：“这如何具体应用于案例中的人或行为？”另一个陷阱是只作描述而不作评估。使用评估性表述，如“这是一个弱点，因为……”或“在实践中，这可能很困难，因为……”。还要避免只呈现一种观点的不平衡答案。即便你强烈赞同，也要展示你理解其他立场。

Finally, rush leads to superficiality. Take a minute to plan: jot down two bullet points per theory before you start writing. A plan ensures you cover AO2 (application) and AO3 (evaluation) with aim, rather than just AO1.

最后，匆忙会导致肤浅。花一分钟时间构思：在动笔前，为每种理论写下两个要点。提纲能确保你有目标地覆盖AO2（应用）和AO3（评估），而不只是AO1。

12. Summary and Revision Tips | 总结与备考建议

Case study mastery is a skill that improves with deliberate practice. Take past-paper cases, or invent scenarios from news headlines, and apply at least two contrasting theories under timed conditions. Compare your answers with model responses, if available, to see how top evaluators weave together application and criticism. Create a one-page summary sheet for each ethical theory listing key features, a standard application template, and two major strengths/weaknesses. For religious ethics, compile a bank of quotations and their meaning.

案例分析是一种通过刻意练习来提高的技能。拿历年考题案例，或者从新闻头条中虚构场景，在限时条件下至少运用两种对立的理论。如有范例答案，对比自己的回答，看看高分评析是如何把应用与批评交织在一起的。为每种伦理理论制作一页摘要表，列出关键特征、标准应用模板以及两个主要优缺点。对于宗教伦理学，编纂一个引语及其含义的语库。

Remember: examiners are not looking for the ‘right answer’ but for a well-supported, critical argument. Your voice should be that of a fair-minded philosopher, carefully weighing evidence before reaching a judgement. With these strategies, you can face any IGCSE Edexcel Philosophy case study with confidence.

记住：考官寻找的不是“正确答案”，而是一个有充分支撑的批判性论证。你的声音应当是一位公正的哲学家，在做出判断之前仔细权衡证据。有了这些策略，你就能自信地应对任何IGCSE Edexcel哲学案例分析题。
