📚 Year 13 AQA Philosophy: Case Study Practical Exercises | 案例分析实战演练
The AQA A-level Philosophy exam demands more than just recalling theories; it requires you to apply philosophical concepts to unfamiliar scenarios and construct critical evaluations under time pressure. This article provides a series of case study practical exercises designed to sharpen your analytical skills across ethics, epistemology, and philosophy of mind. Each case is paired with a structured approach, model analysis, and tips for high-band essay writing.
AQA A-level 哲学考试不仅要求你记忆理论，还要求你将哲学概念应用到陌生情境中，并在时间压力下构建批判性评估。本文提供一系列案例分析实战演练，旨在提升你在伦理学、知识论和心灵哲学领域的分析能力。每个案例都配有结构化的解题方法、示范分析和高分论文写作技巧。
1. Understanding the AQA Case Study Format | 理解AQA案例分析题型
The AQA Philosophy papers (Paper 1 and Paper 2) include 3, 5, 12, and 25-mark questions. The 25-mark essay often presents a short case study or a quotation, asking you to apply philosophical theories to it. Success depends on your ability to quickly identify the relevant philosophical issue, outline the key concepts from the syllabus, and evaluate competing perspectives with precise examples.
AQA 哲学试卷（卷一卷二）包含3分、5分、12分和25分题。25分论文题往往给出一个简短的案例或引文，要求你将哲学理论应用于其中。成功的关键在于快速识别相关的哲学议题，列出大纲中的核心概念，并用准确的例子评估相互竞争的观点。
To excel, you should treat every case study as a puzzle: first, clarify the underlying problem (e.g., ‘Is this instance of lying morally permissible?’), then select the most relevant philosophical framework (Utilitarianism, Kantian ethics, etc.), apply it step by step, and finally weigh up its strengths and limitations in the given context.
要取得优异成绩，你应该把每个案例视为谜题：首先，澄清潜在问题（例如，“这个说谎行为在道德上是否允许？”），然后选择最相关的哲学框架（功利主义、康德伦理学等），逐步应用它，最后在给定语境中权衡其优点和局限。
2. Case Study: The Trolley Problem Reimagined | 案例分析：重构电车难题
Imagine you are a surgeon with five patients each needing a different organ transplant to survive. A healthy traveller walks into your clinic for a routine check-up. Would it be morally acceptable to kill the traveller and harvest their organs to save the five? This is a variation of the classic trolley problem, here pushing ethical principles to their limits.
设想你是一名外科医生，有五位病人各需要不同的器官移植才能存活。一个健康的旅行者走进诊所做常规体检。杀死这位旅行者，摘取他的器官来救五个人，这在道德上可以接受吗？这是经典电车难题的变体，将伦理原则推到了极限。
The case forces you to examine whether numbers alone determine moral permissibility, and whether the method of killing (directly and intentionally vs. as a foreseen side-effect) matters. In your essay, begin by clearly stating the ethical dilemma: the conflict between the duty not to kill and the desire to maximise welfare.
这个案例迫使你审视：是否仅由数量决定道德允许性，以及杀人方式（直接故意 vs. 可预见的副作用）是否重要。在论文中，首先要清楚阐述伦理困境：不可杀人的义务与最大化福祉的愿望之间的冲突。
3. Utilitarian Analysis of the Transplant Case | 移植案例的功利主义分析
From an act-utilitarian perspective (Bentham), the action that produces the greatest happiness for the greatest number is right. Killing the traveller saves five lives at the cost of one, resulting in a net gain of four lives. The surgeon would calculate the pleasures and pains: the five patients’ future happiness outweighs the traveller’s lost happiness and the brief pain of death. Therefore, act-utilitarianism seems to endorse harvesting the organs.
从行为功利主义（边沁）的角度看，产生最大多数人最大幸福的行为就是正确的。杀死旅行者以一条命换五条命，净增四条命。医生会计算快乐与痛苦：五位病人未来的幸福超过了旅行者失去的幸福和死亡的短暂痛苦。因此，行为功利主义似乎赞同摘取器官。
Rule-utilitarianism (Mill), however, would consider the long-term consequences of adopting a rule that permits doctors to kill innocent healthy people for their organs. Such a rule would create widespread fear, undermine trust in healthcare, and ultimately reduce overall happiness. Thus, rule-utilitarianism would reject the killing, demonstrating the theory’s ability to align with common moral intuitions.
然而，规则功利主义（密尔）会考量采纳一条允许医生为获取器官而杀死无辜健康者的规则所带来的长远后果。这样的规则会引发普遍恐惧，破坏对医疗的信任，最终降低总体幸福。因此，规则功利主义会拒绝杀人，显示出该理论与常见道德直觉相吻合的能力。
4. Kantian Deontology and the Organ Harvesting Dilemma | 康德义务论与器官收割困境
Kant’s ethics would categorically forbid using the traveller merely as a means to save the five. The surgeon’s maxim would be: ‘When I can save several lives by killing an innocent person, I will kill that person.’ This maxim cannot be universalised without contradiction because a world where such killing is permitted would destroy the very trust and security that make rational action possible. Additionally, the traveller is treated solely as a tool, violating the Formula of Humanity.
康德的伦理学将断然禁止仅仅把旅行者当作救五个人的工具。医生的准则是：“当我能通过杀死一个无辜者来挽救几条生命时，我会杀死那个人。”这条准则无法不自相矛盾地普遍化，因为一个允许此类杀戮的世界会摧毁使理性行动成为可能的信任与安全。此外，旅行者被单纯当作工具对待，违反了“人作为目的”的公式。
Kant’s absolute prohibition on lying and killing provides a clear, rule-based answer. Yet you must evaluate its counter-intuitive consequences: can it be right to let five die to avoid treating one as a means? This is where many students strengthen their essays by showing the tension between Kant’s consistency and the emotional pull of saving lives.
康德对说谎和杀人的绝对禁止提供了清晰、基于规则的答案。但你必须评估其反直觉的后果：为了避免将一个人当作手段而让五个人死去，这能是正确的吗？正是在这里，许多学生通过展示康德的连贯性与救人冲动之间的张力，来强化自己的论文。
5. Virtue Ethics and the Caring Surgeon | 美德伦理学与关心病患的外科医生
Virtue ethics (Aristotle) asks what a virtuous agent would do. A compassionate and wise doctor would not murder an innocent; instead, they would exercise the virtue of phronesis (practical wisdom) to find a third way — perhaps campaigning for organ donation, or prioritising care while acknowledging the tragic limits of medicine. The viciousness of cold-blooded killing would corrupt the agent’s character, leading away from eudaimonia.
美德伦理学（亚里士多德）追问有德之人会怎么做。一个富有同情心和智慧的医生不会谋杀无辜者；相反，他们会运用实践智慧来寻找第三条道路——也许是通过宣传器官捐献，或者在承认医学的悲剧性局限的同时优先提供关怀。冷血杀人的恶会腐蚀行为者的品格，使其远离幸福。
Critics argue that virtue ethics lacks clear action-guidance: in an emergency where no third way exists, the theory seems silent. However, defenders claim that the very notion of a ‘tragic dilemma’ shows the limits of rule-based theories, and that virtue ethics captures the importance of emotional responses and moral regret — essential elements in any rich case study discussion.
批评者认为，美德伦理学缺乏明确的行动指导：在没有第三条路的紧急情况下，该理论似乎保持沉默。然而，辩护者主张，“悲剧性困境”这一概念本身就显示了规则伦理的局限，而美德伦理学捕捉到了情感反应和道德遗憾的重要性——这些是任何丰富案例讨论中的核心要素。
6. Epistemology: The Gettier-Style Case | 知识论：盖梯尔式案例
Consider this scenario: Smith believes that Jones owns a Ford because he has seen Jones driving a Ford for years. From this, Smith validly deduces ‘Either Jones owns a Ford or Brown is in Barcelona’, even though he has no idea where Brown is. As it turns out, Jones has sold his car and is renting a Ford, but coincidentally Brown is indeed in Barcelona. Smith’s belief is true and justified, yet it seems not to count as knowledge. Such Gettier cases test your ability to explain the tripartite definition of knowledge and its vulnerabilities.
考虑这个场景：史密斯相信琼斯拥有一辆福特车，因为他多年来都看到琼斯开着一辆福特。基于此，史密斯有效推导出“要么琼斯拥有一辆福特车，要么布朗在巴塞罗那”，尽管他完全不知道布朗在哪里。结果，琼斯已经卖掉了车而是租的福特，但巧合的是布朗确实在巴塞罗那。史密斯的信念为真且得到辩护，但似乎算不上知识。这类盖梯尔案例考验你解释知识三元定义及其弱点。
In your essay, you must first outline the JTB (Justified True Belief) account: S knows that p iff (i) p is true, (ii) S believes that p, and (iii) S is justified in believing that p. Then show precisely where the Gettier case breaks down — Smith’s justification relies on a false lemma (that Jones owns a Ford), introducing luck into the truth of the deduced belief.
在论文中，你必须先概述JTB（真确辩护信念）理论：S知道p，当且仅当(i) p为真，(ii) S相信p，且(iii) S有辩护地相信p。然后准确指出盖梯尔案例在何处失效——史密斯的辩护依赖一个虚假前提（琼斯拥有一辆福特车），从而在推导信念的真值中引入了运气因素。
7. Resolving Gettier: No False Lemmas and Reliabilism | 解决盖梯尔难题：无虚假前提与可靠论
One response is to add a ‘no false lemmas’ condition: knowledge is justified true belief not inferred from any false statement. Smith’s belief is inferred from the false lemma ‘Jones owns a Ford’, so it fails the new condition. This elegantly handles many Gettier cases but faces the challenge of defining ‘inferred from’ in borderline cases — e.g., if Smith had multiple overlapping reasons, some false, some true.
一种回应是添加“无虚假前提”条件：知识是不依赖任何虚假陈述推导出的真确辩护信念。史密斯的信念是从虚假前提“琼斯拥有一辆福特”推导而来，因此不满足新条件。这个方案巧妙处理了许多盖梯尔案例，但面临界定“推导自”的挑战——例如，如果史密斯有多个重叠的理由，有些假有些真。
Reliabilism (Goldman) proposes that knowledge is true belief produced by a reliable cognitive process. Smith’s deduction from a false belief is not reliable, because it depends on a defective source. However, the possibility of a ‘reliable demon world’ (where a demon makes us systematically wrong) shows that reliabilism struggles with epistemic luck. Discussing these counterexamples demonstrates the high-level evaluative skills AQA examiners look for.
可靠论（戈德曼）提出，知识是由可靠的认知过程产生的真信念。史密斯从虚假信念进行的推导并不可靠，因为它依赖于一个有缺陷的信息源。然而，“可靠的恶魔世界”的可能性（恶魔让我们系统性地出错）表明可靠论难以处理认知运气。讨论这些反例展现了AQA考官所寻找的高阶评估技能。
8. Philosophy of Mind: The Chinese Room Argument | 心灵哲学：中文房间论证
Searle’s Chinese Room targets functionalism and strong AI. Imagine Searle locked in a room with a rulebook that tells him how to manipulate Chinese symbols. He receives Chinese characters slipped under the door, follows the rules, and outputs appropriate Chinese characters — all without understanding a word of Chinese. Functionalism would say the room runs the right program, so it has understanding, but Searle’s intuition is that no understanding takes place. This case study is classic for essays on mental states and intentionality.
塞尔的中文房间攻击功能主义和强人工智能。设想塞尔被锁在一个房间里，手边有一本规则手册，告诉他如何操作中文符号。他接收从门缝塞进来的中文字符，按照规则输出恰当的中文字符——自己却完全不懂中文。功能主义会说，房间运行了正确的程序，因此具备理解力，但塞尔直觉认为并未产生任何理解。这个案例是探讨心理状态与意向性的经典素材。
To tackle this in an exam, outline functionalism: mental states are functional states defined by their causal roles (input, output, and relations to other mental states). Then explain Searle’s challenge: syntax (symbol manipulation) is insufficient for semantics (meaning and understanding). Evaluate by considering the Systems Reply (the whole system, not just Searle, understands) and Searle’s rejoinder that a person could internalise all the rules and still have no understanding.
在考试中处理这个论题，需先概述功能主义：心理状态是由其因果角色（输入、输出及与其他心理状态的关系）所定义的功能状态。然后解释塞尔的挑战：句法（符号操作）不足以产生语义（意义和理解）。评估时要考虑系统回应（是整个系统，而非只有塞尔，才具有理解力）以及塞尔的回应：一个人可以将所有规则内在化而仍然没有理解。
9. Property Dualism and the Philosophical Zombie | 属性二元论与哲学僵尸
Chalmers’ zombie argument is a powerful case study for property dualism. A philosophical zombie is a creature physically identical to a human but lacking phenomenal consciousness — ‘all is dark inside’. If zombies are conceivable, then consciousness is not logically supervenient on physical facts, meaning there are non-physical properties. This is used to challenge physicalist theories like identity theory and functionalism.
查尔默斯的僵尸论证是属性二元论的强有力案例。哲学僵尸是一种在物理上与人完全相同但缺乏现象意识的生物——“内心一片黑暗”。如果僵尸是可设想的，那么意识并不逻辑地随附于物理事实之上，这意味着存在非物理的属性。这被用来挑战同一论和功能主义等物理主义理论。
In your essay, distinguish between metaphysical possibility and mere conceivability. Physicalists can reply that conceivability does not entail possibility (the ‘phenomenal concept strategy’ or the ‘imagination is guided by ignorance’ reply). Alternatively, they might deny that zombies are genuinely conceivable — when we try to imagine one, we are merely imagining missing something from our third-person perspective, not realising that physical duplication necessarily duplicates consciousness.
在论文中，要区分形上学可能性与单纯的可设想性。物理主义者可以回应说，可设想并不蕴含可能性（“现象概念策略”或“想象受无知引导”的回应）。或者，他们可以否认僵尸真的是可设想的——当我们试图想象一个僵尸时，我们只是从第三人称视角想象缺少了什么，而没有意识到物理复制必然也复制了意识。
10. Integrating Case Studies into High-Scoring Responses | 将案例融入高分答案
The highest marks go to students who seamlessly integrate case study details into their analysis and evaluation. Instead of treating the case as an afterthought, use it as the backbone of your argument. Begin each paragraph by referencing a specific aspect of the case, then bring in the philosophical theory to illuminate it, and finally evaluate how the theory copes — or fails — in that light.
最高分的获得者会将案例细节无缝融入分析与评估之中。不要将案例当作事后添加的东西，而要将其作为论点的支柱。每一段开头先提及案例的一个具体方面，然后引入哲学理论来阐明它，最后评估该理论在这方面是成功还是失败。
For example: ‘In the transplant scenario, the act-utilitarian’s calculation ignores the doctor’s inherent role-related duties. Kant would highlight that the doctor’s medical oath creates a perfect duty to do no harm, irrespective of consequences. However, virtue ethics might question whether taking the oath is enough — the truly virtuous character is what ensures the surgeon never even considers such an act.’ Such connected reasoning demonstrates the synoptic skill valued by AQA.
例如：“在移植场景中，行为功利主义的计算忽略了医生内在的角色责任。康德会强调，医学生的誓言构成了一个不伤害的完全义务，不论后果如何。然而，美德伦理学会质疑仅仅发誓是否足够——真正有德的品格才能确保外科医生甚至从不考虑这样的行为。”这种环环相扣的推理展示了AQA所重视的综合分析技能。
11. Common Pitfalls and How to Avoid Them | 常见误区及避免方法
One major mistake is spending too long describing the case or the theory without analysis. AQA assessment objectives award marks for explaining (AO1) and evaluating (AO2). After a very brief description, devote at least 80% of your word count to evaluating — comparing theories, considering counterarguments, and weighing up philosophical positions.
一个主要错误是花费过多时间描述案例或理论而缺乏分析。AQA的评估目标对解释（AO1）和评估（AO2）分别给分。在极简短的描述之后，至少将80%的字数用于评估——比较理论、考量反论证、权衡哲学立场。
Another pitfall is using vague language like ‘some philosophers think’ without naming them. Specificity matters: refer to Bentham, Kant, Aristotle, Chalmers, etc. Also, avoid narrative description of case studies in favour of philosophically charged analysis. Finally, always link your conclusions back to the case — a clunky ‘in conclusion the theory works’ is weak; instead, ‘Thus, in the organ transplant case, utilitarianism’s arithmeticism leads to a conclusion that deeply conflicts with our considered moral judgments, revealing a fundamental limit…’ shows mastery.
另一个误区是使用诸如“一些哲学家认为”之类的模糊语言而不指名道姓。具体性很重要：要提及边沁、康德、亚里士多德、查尔默斯等。还要避免对案例进行叙述式描述，而应采用富有哲学深度的分析。最后，务必将结论与案例联系回扣——生硬的“总之该理论可行”是薄弱的；而“因此，在器官移植案例中，功利主义的算术主义得出的结论与我们深思熟虑的道德判断产生深刻冲突，揭示了根本性的局限……”则显示了掌握程度。
12. Practice Makes Permanent: Sample Outlines | 不断练习：示范提纲
Below is a quick-outline structure you can adapt for any case study:
1. Identify the central philosophical problem in one sentence.
2. State which theory/theories you will use.
3. Apply first theory with clear reference to the case.
4. Critically evaluate that application.
5. Introduce a competing theory and show its contrasting verdict.
6. Weigh up which approach is more defensible, considering objections and replies.
7. Conclude with a nuanced verdict that recognises complexity.
以下是一个你可以用于任何案例的快速提纲结构：
1. 用一句话识别核心哲学问题。
2. 说明你将使用哪个/哪些理论。
3. 应用第一个理论并明确联系案例。
4. 批判性地评估该应用。
5. 引入相互竞争的理论，展示其不同判断。
6. 权衡哪种进路更可辩护，考虑反驳与回应。
7. 以承认复杂性的细致判断作为结论。
Test yourself with novel scenarios: ‘A scientist artificially creates a conscious AI; does it have moral rights?’ Apply utilitarianism (would it cause pain?), Kantianism (does it have rational autonomy?), and then assess whether the concept of ‘consciousness’ itself can be satisfactorily defined. The more you practise, the more agile you become at flexibly deploying your knowledge. Use the quick-outline to plan 5-minute essay frameworks regularly before the exam.
用新奇场景测试自己：“一名科学家人工创造了一个有意识的人工智能；它是否拥有道德权利？” 应用功利主义（它会引发痛苦吗？）、康德主义（它拥有理性自主吗？），然后评估“意识”这个概念本身能否被充分定义。你练习得越多，就越能灵活运用你的知识。在考前定期使用快速提纲规划5分钟的论文框架。
