📚 IGCSE Cambridge Philosophy: Case Study Practical Drill | IGCSE 剑桥哲学：案例分析实战演练
Case studies appear throughout the Cambridge IGCSE Philosophy syllabus, from ethics and political philosophy to epistemology and philosophy of mind. They test not only what you remember but how well you can apply, compare and evaluate philosophical ideas under timed conditions. This drill gives you a repeatable method and worked examples.
案例分析贯穿剑桥 IGCSE 哲学大纲，从伦理学、政治哲学到认识论和心灵哲学。它们不仅考查你记住了什么，更考查你在限时条件下如何应用、比较和评估哲学观点。本次实战演练提供一个可复用的方法，并配有完整范例。
1. Why Case Analysis Matters in IGCSE Philosophy | 为什么案例分析在 IGCSE 哲学中重要
Case analysis questions often begin with a short scenario, quote or dilemma and then ask you to explain, apply, discuss or evaluate. Examiners use these questions to distinguish between candidates who only describe theories and those who can use them flexibly.
案例分析题通常先给出一段简短情境、引文或两难，然后要求你解释、应用、讨论或评估。考官用这类题区分只会描述理论的考生，与能够灵活运用理论的考生。
The scenario is not decoration; it supplies the key facts. Your first task is to identify the philosophical issue hidden in the case, such as whether a lie is ever justified, or whether we can know that other minds exist.
情境不是装饰，它提供关键事实。你的第一项任务是识别案例中隐藏的哲学问题，例如谎言是否有时正当，或者我们能否知道其他心灵存在。
2. The Four-Step Drill for Any Case | 任何案例的四步演练法
Use this repeatable sequence: Step 1 Identify the issue and key terms. Step 2 State two or more relevant theories or positions. Step 3 Apply each theory explicitly to the case, using its own concepts. Step 4 Evaluate by raising an objection, a counterexample or a strength.
使用这个可重复的步骤：第一步，识别问题和关键术语；第二步，陈述两个或更多相关理论或立场；第三步，明确将每个理论应用于案例，使用该理论自身的概念；第四步，通过提出异议、反例或优势进行评估。
Many answers fail because they skip Step 3 and write a general essay about a theory. In IGCSE Philosophy, application points are often where marks are awarded. Use phrases such as ‘A utilitarian would argue that…’ or ‘A deontologist would reject this because…’
许多答案失分是因为跳过了第三步，把文章写成对某个理论的泛泛介绍。在 IGCSE 哲学中，应用点往往才是得分点。使用诸如 ‘一个功利主义者会主张……’ 或 ‘一个义务论者会拒绝这一点，因为……’ 的表述。
3. Ethics Case Drill – The Trolley Variant | 伦理学案例演练：电车变体
A runaway trolley is heading towards five workers. You are standing by a lever: if you pull it, the trolley switches to a side track where one worker is trapped. You can either do nothing and let five die, or pull the lever and one dies.
一辆失控电车驶向五名工人。你站在一个拉杆旁：拉动拉杆，电车会转向侧轨，而侧轨上有一名工人被困。你可以什么都不做让五人死亡，或拉动拉杆让一人死亡。
A rule utilitarian may pull the lever because the general rule ‘save the greater number’ tends to maximise welfare. An act utilitarian calculates the specific consequences: five lives outweigh one. A Kantian deontologist, however, focuses on the maxim of your action – using the one worker as a means to save others, which may violate the categorical imperative.
规则功利主义者可能拉动拉杆，因为 ‘拯救更多人’ 的一般规则倾向于使福利最大化。行为功利主义者计算具体后果：五条生命重于一条。而康德式义务论者关注你行为的准则——把那名工人当作拯救他人的手段，这可能违反定言命令。
A strength of utilitarianism here is that it gives a clear decision procedure. A weakness is that it seems to ignore individual rights and the distinction between letting die and killing. A deontologist may be accused of being too rigid when refusing to pull the lever, but this consistency protects human dignity.
功利主义在此的优势是提供了一个清晰的决策程序；其弱点则是似乎忽略个人权利以及 ‘任其死亡’ 和 ‘杀人’ 的区别。义务论者可能被指责在拒绝拉杆时过于僵化，但这种一致性保护了人的尊严。
4. Epistemology Case Drill – The Brain in a Vat | 认识论案例演练：缸中之脑
Imagine your brain has been removed and placed in a vat of nutrients, connected to a supercomputer that feeds you the same experiences you have now. Can you know that you are not a brain in a vat?
设想你的大脑被取出，放在一个营养缸中，连接到一台超级计算机，它向你输入与你当前完全相同的体验。你能知道你不是一个缸中之脑吗？
A sceptic uses this case to argue that because your evidence would be identical in both the normal world and the vat world, you cannot have knowledge. A reliabilist replies that if your belief is caused by a reliable process, it can count as knowledge; the mere possibility of error does not destroy knowledge. A Cartesian foundationalist might search for an indubitable foundation such as ‘I think, therefore I am’.
怀疑论者用这个案例论证：由于你在正常世界和缸中世界的证据完全相同，你不可能拥有知识。可靠主义者回应说，如果你的信念由可靠过程引起，它就可以算作知识；仅仅存在错误的可能性并不会摧毁知识。笛卡尔式基础主义者可能会寻找一个不可怀疑的基础，例如 ‘我思故我在’。
The sceptical conclusion is logically possible but practically empty – we cannot live as if it were true. The reliabilist response is useful but may struggle to show that the process is reliable without circular reasoning.
怀疑论的结论在逻辑上可能，但在实践中是空洞的——我们无法把它当作真实来生活。可靠主义的回应很有用，但可能难以在不陷入循环推理的情况下证明该过程是可靠的。
5. Political Philosophy Case Drill – Taxation and Freedom | 政治哲学案例演练：税收与自由
A government raises income tax on high earners to fund free healthcare and education for all citizens. Some argue this is fair redistribution; others argue it is theft of private property.
政府提高高收入者的所得税，为全体公民的免费医疗和教育提供资金。一些人认为这是公平的再分配；另一些人则认为这是对私有财产的盗窃。
A Rawlsian would support the policy if it satisfies the difference principle: inequalities are acceptable only if they improve the position of the least advantaged. A Nozickian libertarian would reject coercive taxation because it violates self-ownership and treats the state as a rights-violating agent. A utilitarian would ask whether the policy maximises overall happiness, not whether it is ‘fair’ in itself.
罗尔斯主义者会支持这项政策，如果它满足差别原则：不平等只有在改善最不利者地位时才可接受。诺齐克式自由至上主义者会反对强制性税收，因为它侵犯自我所有权，把国家视为侵犯权利的行动者。功利主义者则会问该政策是否使总体幸福最大化，而不是它本身是否 ‘公平’。
The case tests tensions between liberty and equality. Rawls gives a strong justification for redistribution but may underestimate individual liberty. Nozick protects liberty but offers little response to extreme poverty. Use this contrast to show evaluative balance.
这个案例检验自由与平等之间的张力。罗尔斯为再分配提供了有力辩护，但可能低估个人自由。诺齐克保护了自由，却对极端贫困几乎无法回应。用这种对比来展现评估的平衡性。
6. Religious Philosophy Case Drill – The Problem of Evil | 宗教哲学案例演练：恶的问题
A natural disaster kills thousands of innocent people. If God is omnipotent and omnibenevolent, why would such evil exist?
一场自然灾害夺去数千名无辜者的生命。如果上帝是全能和全善的，为什么会有这样的恶存在？
The logical problem argues that the set of beliefs ‘God is all-powerful, God is all-good, evil exists’ is inconsistent. An Augustinian theodicy claims evil is a privation of good, caused by free will and the fall; natural evil is a consequence of a broken order. An Irenaean theodicy argues evil is necessary for soul-making and the development of moral character.
逻辑恶的问题论证 ‘上帝全能、上帝全善、恶存在’ 这组信念不一致。奥古斯丁神义论声称恶是善的缺乏，由自由意志和堕落造成；自然恶是秩序破碎的结果。爱任纽神义论则认为恶对于灵魂塑造和道德品格的发展是必要的。
The Augustinian reply may struggle to explain natural evil before human choice existed, and a perfect creation falling seems puzzling. The Irenaean reply gives a positive purpose to suffering, but not all suffering seems proportionate or character-building. A candidate who notes both strengths and weaknesses will score higher on evaluation.
奥古斯丁的回应难以解释在人类选择之前就存在的自然恶，而且一个完美创造物的堕落似乎令人费解。爱任纽的回应赋予了苦难积极目的，但并非所有苦难都显得成比例或有助于塑造品格。能够同时指出优点和弱点的考生在评估上得分更高。
7. Philosophy of Mind Case Drill – The Turing Test and Other Minds | 心灵哲学案例演练：图灵测试与他心
You chat online with an AI. Its answers are indistinguishable from a human. Does this show that the AI has a mind, or that you can know other minds exist?
你在网上与一个 AI 聊天。它的回答与人类无法区分。这是否表明该 AI 拥有心灵，或者你能够知道其他心灵存在？
A functionalist might say that if the AI has the right functional states and causal roles, it has a mind – at least in one sense. A behaviourist would say mental states are dispositions to behave, so passing the Turing test is strong evidence of mind. A property dualist might object that subjective experience, or qualia, could be absent even if behaviour is perfect.
功能主义者可能会说，如果 AI 拥有正确的功能状态和因果角色，它就拥有心灵——至少在某种意义上。行为主义者会说心灵状态就是行为倾向，因此通过图灵测试是心灵存在的有力证据。属性二元论者可能反驳说，即使行为完美，主观体验或感受质也可能缺失。
The Turing test is a good operational test but may confuse simulation with genuine mentality. The Chinese room argument by Searle challenges this: syntactic manipulation of symbols does not produce semantic understanding. Use this to evaluate the limits of behavioural evidence.
图灵测试是一个很好的操作性测试，但可能混淆模拟与真正的心智。塞尔的中文房间论证对此提出挑战：对符号的句法操作不会产生语义理解。用这一点来评估行为证据的限度。
8. Argument Analysis – Spotting Fallacies and Counterexamples | 论证分析：识别谬误与反例
Case-based questions often include arguments that you must evaluate. Learn to spot common flaws: ad hominem (attacking the person), straw man (misrepresenting a view), false dilemma (only two options when more exist), and slippery slope (unjustified chain of consequences).
基于案例的题目常常包含你必须评估的论证。学会识别常见谬误：人身攻击（攻击人而非论点）、稻草人（歪曲对方观点）、假两难（只给出两个选项而实际存在更多）、滑坡（未经证明的连锁后果）。
