📚 AS AQA Philosophy: Case Study Practice and Analysis | AS AQA 哲学：案例分析实战演练
Case studies are at the heart of the AS AQA Philosophy examination. They test your ability not just to recall theories but to apply them to novel, often morally or epistemologically complex situations. This article provides a structured, bilingual guide to mastering case study analysis, from moral dilemmas to epistemological puzzles, with worked examples, examiner tips, and practice exercises.
案例分析是 AS AQA 哲学考试的核心。它不仅考察你对理论的记忆，更考察你将理论应用于新颖且常常在道德或认识论上复杂情境的能力。本文提供一份结构化的双语指南，帮助你掌握案例分析，涵盖道德困境与认识论谜题，并配有范例、考官建议与练习。
1. What is a Case Study in Philosophy? | 什么是哲学案例分析？
A philosophical case study is a concrete scenario – real or imagined – that challenges a theory, reveals an inconsistency, or demands a reasoned moral judgement. In the exam, you may be asked to apply utilitarianism to a trolley problem, assess a Gettier-style case against the tripartite definition of knowledge, or explain how a sense-data theory handles perceptual illusion.
哲学案例分析是一个具体的情景——无论是真实的还是想象的——它挑战某一理论，揭示其不一致性，或要求做出理性的道德判断。在考试中，你可能会被要求将功利主义应用于电车难题，针对知识的三要素定义评估一个盖梯尔式案例，或解释感觉材料理论如何处理知觉错觉。
The key skill is not simply describing the theory but showing how it engages with the details of the case. You must demonstrate critical evaluation, compare alternative interpretations, and justify your conclusion with clear reasoning.
关键技能不仅仅是描述理论，而是展示该理论如何处理案例的细节。你必须展现批判性评价，比较不同的解释，并以清晰的推理来论证你的结论。
2. The Structure of a Philosophical Case Study Response | 哲学案例分析作答的结构
A high-scoring response follows a clear, logical structure. Start with a brief identification of the relevant philosophical issue or concept. Then state the theory you intend to apply, giving a concise definition of its core principles. Next, apply the theory systematically to the case, highlighting where it provides a plausible answer and where it faces difficulties.
高分作答遵循清晰且有逻辑的结构。首先简要指出相关的哲学议题或概念。然后陈述你打算应用的理论，简明定义其核心原则。接下来，系统地将理论应用于案例，指出它在哪里提供了合理的答案，以及在哪里遇到了困难。
You should anticipate objections: if you are using utilitarianism, consider how a Kantian deontologist would respond to the same case. Finally, offer a balanced evaluation and a justified conclusion. This structure ensures depth, comparison, and critical analysis – essential for top band marks.
你应当预见到反对意见：如果你在使用功利主义，考虑一下康德义务论者会对同样的案例作何反应。最后，提供一个平衡的评价和一个有理有据的结论。这样的结构保证了深度、比较和批判性分析——这是获得最高评分的必要条件。
| Step | Action |
| 1 | Identify the philosophical issue |
| 2 | Define the theory clearly |
| 3 | Apply the theory step by step |
| 4 | Introduce and evaluate an alternative |
| 5 | Reach a balanced conclusion |
3. Case Study 1: The Trolley Problem and Utilitarianism | 案例一：电车难题与功利主义
A runaway trolley is heading towards five people tied to the track. You can pull a lever to divert it onto a side track, where one person is tied. Utilitarianism, especially act utilitarianism, would require you to pull the lever: sacrificing one to save five maximises overall happiness and minimises pain – the principle of utility is satisfied.
一辆失控的电车正冲向被绑在主轨道上的五个人。你可以扳动道岔，让电车转向侧线，而侧线上绑着一个人。功利主义，特别是行为功利主义，会要求你扳动道岔：牺牲一人拯救五人，使总体的幸福最大化、痛苦最小化——功利原则得到了满足。
However, a critic might object that this treats the lone individual merely as a means to an end. Kantian ethics would forbid using a person without their consent, regardless of the consequences. Moreover, if the scenario is altered (e.g., pushing a large man off a bridge to stop the trolley), even some utilitarians feel uneasy, revealing a tension between act and rule utilitarianism.
然而，批评者可能会反驳说，这仅仅把那个单独的个体当作了手段。康德伦理学禁止未经同意而利用一个人，不管后果如何。此外，如果场景改变（例如，把一个大个子男人推下桥以阻止电车），即便是某些功利主义者也会感到不安，这揭示了行为功利主义与规则功利主义之间的张力。
In your answer, you must weigh whether the utilitarian calculus provides a fully satisfying moral guide or whether it overlooks rights and justice. Mention the distinction between quantitative and qualitative pleasure if drawing on Mill.
在你的答案中，你必须权衡功利主义的计算是否提供了一个完全令人满意的道德指南，还是它忽视了权利与正义。如果引用密尔，要提到量的快乐与质的快乐之间的区分。
4. Case Study 2: The Lying Promise and Kantian Ethics | 案例二：撒谎的承诺与康德伦理学
Imagine you need to borrow money and promise to repay it next week, knowing you will not be able to do so. Kant’s first formulation of the categorical imperative – the formula of universal law – asks: can you consistently will that everyone should make false promises? The answer is no, because if everyone did so, the institution of promising would collapse, and your own false promise would become impossible.
假设你需要借钱，并承诺下周还钱，尽管你明知自己无法做到。康德的绝对命令的第一个表述——普遍法则公式——会问：你能否始终如一地意愿所有人都作出虚假承诺？答案是不能，因为如果所有人都这样做，承诺这一制度就会崩溃，你自己的虚假承诺也将无从实现。
Kant’s second formulation – the formula of humanity – insists that you never treat another person merely as a means but always as an end in themselves. A lying promise uses the lender solely as a tool to obtain money, violating their rational autonomy. Therefore, lying promises are always impermissible, no matter how beneficial the consequences.
康德的第二个表述——人性公式——强调你绝不能只把他人当作手段，而应始终将其视为目的本身。一个撒谎的承诺仅仅把借款人当作获取金钱的工具，侵犯了他们的理性自律。因此，撒谎的承诺永远不被允许，无论后果多么有利。
A typical exam task would be to discuss whether this absolutist stance is too rigid. Would Kant really forbid lying to a would-be murderer at the door? This challenge tests your ability to defend or critique Kantian deontology in the light of extreme cases.
典型的考试任务是讨论这种绝对主义立场是否过于僵化。康德真的会禁止对门口意欲行凶者撒谎吗？这一挑战考验你能否根据极端案例为康德义务论辩护或提出批判。
5. Case Study 3: Virtue Ethics and a Medical Dilemma | 案例三：美德伦理学与医疗困境
A doctor must decide whether to assist a terminally ill patient who requests physician-assisted dying, which is illegal. Virtue ethics shifts the focus from acts and rules to the character of the agent. The virtuous doctor, according to Aristotle, would aim for the golden mean between extremes. Excessive pity might lead to breaking the law, while a deficiency of compassion might result in cold indifference to suffering.
一位医生必须决定是否协助一位请求医生协助死亡的绝症患者，而这行为是违法的。美德伦理学将焦点从行为与规则转移到行为者的品格上。在亚里士多德看来，有德的医生会追求两极之间的中庸之道。过度的怜悯可能导致违法，而同情心不足则可能导致对苦难漠不关心。
An Aristotelian analysis would consider what the phronimos (the practically wise person) would do in this situation. That person would balance compassion with respect for the law and professional integrity. There is no single right act prescribed in advance; rather, the right act is what a virtuous person would characteristically choose.
亚里士多德式的分析会考虑一个拥有实践智慧的人在此情况下会如何行动。这样的人会在同情心与对法律及职业操守的尊重之间取得平衡。并没有事先规定的唯一正确行为；正确行为恰恰是一个有德之人通常会做出的选择。
Critics argue that virtue ethics provides insufficient concrete guidance for such agonising dilemmas. Your case study response should assess whether this lack of a decision-making procedure is a fatal weakness or a realistic reflection of moral complexity.
批评者认为，美德伦理学对于此类痛苦的两难困境无法提供足够具体的指导。你的案例分析应评价这种缺乏决策程序是一个致命的弱点，还是对道德复杂性的一种现实反映。
6. Case Study 4: The Gettier Problem and Knowledge | 案例四：盖梯尔问题与知识
Since Plato, knowledge has been defined as justified true belief (JTB). In 1963, Edmund Gettier published two counterexamples that shook this definition. In one, Smith has strong evidence that Jones owns a Ford (Smith has seen him driving it) and therefore believes ‘Jones owns a Ford or Brown is in Barcelona’ – a disjunction he justifiably believes, because he knows the first part is true. Unbeknownst to Smith, Jones has sold the Ford, but Brown happens by sheer chance to be in Barcelona. Smith’s belief is true and justified, yet we hesitate to call it knowledge.
自柏拉图以来，知识一直被定义为经过证成的真信念（JTB）。1963年，埃德蒙·盖梯尔发表了两个反例，动摇了这一定义。在其中一例中，史密斯有充分证据相信琼斯拥有一辆福特（史密斯见过琼斯开那辆车），因而他相信“琼斯拥有一辆福特，或者布朗在巴塞罗那”——这是一个他合理相信的选言命题，因为他知道前半部分为真。史密斯不知道的是，琼斯已经卖掉了福特，但布朗纯属巧合地正在巴塞罗那。史密斯的信念为真，且经过证成，但我们却不愿称之为知识。
In exam case studies, you will be given a similar scenario and asked to evaluate whether the JTB definition survives. You must explain why epistemic luck undermines knowledge and consider proposed solutions such as the ‘no false lemmas’ condition or reliabilism.
在考试案例分析中，你会碰到类似的场景，并被要求评述 JTB 定义是否依然成立。你必须解释为何认知运气会破坏知识，并考虑诸如“无假引理”条件或可靠主义等提议的解决方案。
Be sure to articulate why adding a fourth condition creates new problems (e.g., does it rule out too many genuine cases of knowledge?). The Gettier problem remains an open question, and your task is to show awareness of this ongoing philosophical debate.
务必阐明，为何增加第四个条件会带来新的问题（例如，它是否会排除太多真正的知识？）。盖梯尔问题至今仍是一个开放性的问题，你的任务就是展现你对这一持续进行的哲学争论的认知。
7. Case Study 5: Perception – The Müller-Lyer Illusion | 案例五：知觉——穆勒-莱耶错觉
Look at the classic Müller-Lyer lines: two lines of equal length, one with outward-facing arrowheads and one with inward-facing ones. The line with outward arrowheads appears longer. A direct realist, who claims we perceive the world directly and as it is, struggles to explain this persistent illusion. If we perceive the world directly, why does the illusion not vanish once we measure the lines?
请看经典的穆勒-莱耶线条：两条等长的线，一条两端箭头向外，一条箭头向内。箭头向外的线看起来更长。直接实在论者声称我们直接感知世界且如其本然地感知世界，他们难以解释这一持续存在的错觉。如果我们是直接感知世界，为什么即便我们测量了线条，错觉仍不消失？
An indirect realist (or sense-data theorist) argues that we perceive sense-data – mental representations – which can fail to match physical reality. The illusion is explained by saying the sense-data we experience are of different lengths, even though the physical lines are identical. Thus, perception is indirect, mediated by appearances.
间接实在论者（或感觉材料论者）主张，我们感知到的是感觉材料——即心理表征——它们可能与物理实在不相匹配。该错觉可被解释为：我们所经验到的感觉材料具有不同长度，尽管物理线条是相同的。因此，知觉是间接的，通过显象为中介。
An exam case study may ask you to compare how direct realism, indirect realism, and idealism handle a given perceptual illusion. When writing your response, clarify the differences between primary and secondary qualities where relevant.
考试案例分析可能要求你比较直接实在论、间接实在论和观念论如何处理一个给定的知觉错觉。在撰写答案时，若相关，请阐明第一性质与第二性质之间的区别。
8. Case Study 6: Rationalism vs Empiricism in Mathematics | 案例六：数学中的理性主义与经验主义
Consider the mathematical truth ‘7 + 5 = 12’. An empiricist like Hume would argue that all knowledge comes from sensory experience; we learn arithmetic by observing conjoined instances. Yet, how can experience ever justify a universal and necessary truth? We have never checked every possible instance of adding 7 and 5.
考虑“7 + 5 = 12”这一数学真理。像休谟这样的经验主义者会声称，所有知识都来自感官经验；我们通过观察一个个组合实例来学习算术。然而，经验如何能够证成一个普遍且必然的真理？我们从未查验过将7与5相加的每一个可能实例。
A rationalist, following Plato or Descartes, contends that such knowledge is innate or derived through reason alone, independent of the senses. Mathematical truths are necessary, while sense experience can only provide contingent knowledge. The case of a mathematician working out a purely conceptual proof without any empirical input supports the rationalist intuition.
一位遵循柏拉图或笛卡尔路线的理性主义者则主张，此类知识是天赋的，或者仅通过理性推导得出，独立于感官。数学真理是必然的，而感官经验只能提供偶然的知识。一个数学家在不借助任何经验输入的情况下完成纯粹概念性证明的案例，支持了理性主义的直觉。
In your case study analysis, you should also mention Kant’s middle way: that ‘7 + 5 = 12’ is a synthetic a priori judgement, a crucial concept in the AQA specification. Show how Kant’s theory attempts to preserve both necessity and meaningfulness.
在你的案例分析中，还应提到康德的中间路线：“7 + 5 = 12”是一个先天综合判断，这是 AQA 考纲中一个关键的概念。要展示康德的学说如何试图同时保留必然性与有意义性。
9. Common Mistakes in Case Study Analysis | 案例分析中常见的错误
One frequent error is merely retelling the case without philosophical engagement. The exam rewards application, not storytelling. Another is using a theory without defining its terms; for example, invoking the categorical imperative without explaining its formulations weakens your argument.
一个常见错误仅仅是复述案例，却没有哲学上的介入。考试奖励的是应用，而非讲故事。另一个错误是使用一个理论却不定义其术语；例如，援引绝对命令却不解释其公式，会削弱你的论证。
Students also sometimes assert that one theory is ‘better’ than another without providing evaluative criteria. Avoid this by setting clear grounds for comparison: consistency, practical applicability, ability to handle counterexamples, or alignment with moral intuitions. Finally, neglecting alternative viewpoints makes an answer one-sided and limits the mark.
学生有时也会断言某个理论“优于”另一个，却不提供评价标准。要避免这一点，就需设定清晰的比较基础：一致性、实际适用性、处理反例的能力，或者与道德直觉的契合度。最后，忽视替代性观点会使答案变得片面，并限制得分。
- Mistake: Summary without analysis
- Fix: Every descriptive sentence should be followed by evaluative commentary
- 错误：只有概括，没有分析
- 纠正：每一个描述性的句子后都应紧跟评价性的评注
10. Practice: Write Your Own Response | 练习：自己撰写一份答案
Now attempt this sample case: ‘Claire is a utilitarian doctor who has five patients needing different organ transplants. A healthy traveller walks into the surgery for a routine check-up. Should Claire kill the traveller to harvest the organs and save five lives?’ Apply act utilitarianism, then critique it using Kantian ethics and virtue ethics. For each theory, write at least one paragraph applying it and one paragraph evaluating it.
现在尝试这个示例案例：“克莱尔是一位功利主义医生，她手头有五位需要不同器官移植的病人。一位健康的旅行者走进诊所作常规检查。克莱尔是否应该杀死这位旅行者，摘取其器官以拯救五条生命？”运用行为功利主义，然后运用康德伦理学和美德伦理学对其进行批判。对每一种理论，至少写一段应用该理论的段落，再写一段评价它的段落。
After writing, check your answer against the structural model in Section 2. Have you defined the principle of utility? Have you made the distinction between act and rule utilitarianism? Have you considered Williams’ integrity objection? Self-assessment is a powerful tool for improvement.
写完后，对照第 2 节中的结构模型检查你的答案。你是否定义了功利原则？你是否区分了行为功利主义与规则功利主义？你是否考虑了威廉姆斯关于整全性的反驳？自我评估是提升的有力工具。
11. Examiner Tips for High Marks | 夺得高分的考官建议
Examiners consistently report that the strongest responses demonstrate a ‘philosophical conversation’ between theories. Use linking phrases such as ‘A utilitarian would counter that…’ or ‘However, from a deontological perspective…’. This shows an integrated understanding rather than a series of unrelated summaries.
考官们一致报告说，最有力的答案展示了理论之间的“哲学对话”。使用诸如“一个功利主义者可能会反驳说……”或者“然而，从义务论的视角看……”这样的连接性短语。这表明了一种整合性的理解，而非一系列互不相关的概要。
Time management is crucial. Allocate roughly equal time to each part of a multi-theory question. Do not spend too long elaborating the first theory at the expense of depth in the second. Additionally, prioritise clarity over ornamental vocabulary. A precisely defined technical term always earns more credit than a vague, flowery sentence.
时间管理至关重要。对于一道多理论题目，给每个部分分配大致相等的时间。不要在第一个理论上花过长篇幅，从而牺牲第二个理论的深度。另外，要优先追求清晰度，而非华丽的辞藻。一个精确界定的专业术语比一个含糊且花哨的句子更能赢得分数。
- Show the interplay between theories
- Manage time proportionally
- Use technical vocabulary accurately
- 展示理论之间的互动
- 按比例管理时间
- 准确使用专业词汇
12. Conclusion: From Cases to Philosophical Mastery | 结论：从案例到哲学的掌握
Case study practice is not a mere exam technique; it is the very method by which philosophy tests and refines its ideas. Every major philosophical advance, from Gettier’s two-page paper to Thomson’s violinist, has been driven by a carefully crafted case. By practising the strategies outlined here, you build the capacity to think with precision and depth – exactly what the AS AQA Philosophy specification rewards.
案例分析的练习不仅仅是一种应试技巧；它正是哲学用以检验和精炼自身观点的方法。从盖梯尔那篇两页的论文到汤姆森的小提琴家，每一个重大的哲学进展都是由一个精心构造的案例所推动的。通过练习本文所概述的策略，你将建立起精确而深入思考的能力——这正是 AS AQA 哲学考纲所奖励的。
Remember that every case is an opportunity to engage in a living debate. Approach it with curiosity, structure your response with discipline, and always leave space for an alternative voice. That is the mark of a genuine philosophical thinker.
请记住，每一个案例都是一个参与鲜活争论的机会。带着好奇心去接近它，用严格的纪律来组织你的答案，并始终为另一种声音留出空间。这才是一位真正的哲学思考者的标志。
