📚 Case Study Practical Drill for SQA Philosophy | 案例分析实战演练

Case studies lie at the heart of the SQA National 5 Philosophy course. They are not just stories to retell but tools to sharpen your analytical skills. In an exam, you will be asked to identify arguments, evaluate evidence, and construct balanced responses. This article guides you through a step-by-step method for tackling philosophical case studies, complete with worked examples and a practice drill. Whether you are wrestling with ethical dilemmas or sceptical thought experiments, these techniques will help you move from description to genuine philosophical analysis.

案例分析是 SQA National 5 哲学课程的核心。它们不仅仅是用来复述的故事，更是磨砺你分析能力的工具。考试中，你需要识别论证、评估证据并构建平衡的答案。本文将通过分步方法和带样例的实战演练，带你掌握分析哲学案例的技巧。无论你在处理道德困境还是怀疑论思想实验，这些方法都将帮助你从单纯的描述转向真正的哲学分析。

1. What is a Case Study in Philosophy? | 哲学中的案例分析是什么？

In philosophy, a case study is a carefully constructed scenario designed to provoke reflection on fundamental questions. It might be a real-life event, a thought experiment, or a short narrative. Your task is not simply to summarise the story but to extract the conceptual puzzle it presents. For instance, a case about a lying friend is not about the friend; it is about the nature of morality and whether lying can ever be justified. You must identify the philosophical issue, map out any arguments embedded in the scene, and then evaluate those arguments using reasoning, moral theories, or epistemological concepts.

在哲学中，案例研究是一个精心构建的场景，旨在引发对基本问题的反思。它可以是真实事件、思想实验或简短叙述。你的任务不只是概括故事情节，而是提取其中呈现的概念难题。例如，一个关于朋友撒谎的案例，重点不是那位朋友，而是道德的本质以及撒谎是否可能被正名。你必须识别出哲学议题，梳理出场景中蕴含的一切论证，然后运用推理、道德理论或知识论概念来评估这些论证。

2. Step-by-Step Guide to Analysing a Case | 案例分析分步指南

A reliable routine turns an intimidating case into manageable parts. Follow these four stages every time you practise.

一个可靠的例行步骤能把令人望而生畏的案例变得易于处理。每次练习时都遵循这四个阶段。

Stage 1 – Identify: Look for the central philosophical question. Is it about right and wrong, knowledge and doubt, or the meaning of life? Underline key dilemmas.
阶段一——识别：找出核心哲学问题。它是关于对与错、知识与怀疑，还是人生的意义？在关键困境下划线。
Stage 2 – Reconstruct: List the reasons people in the case give for their actions. Turn those reasons into a clear argument with premises and a conclusion. Use an ‘if … then …’ format to reveal the logic.
阶段二——重构：列出案例中人物为自身行为给出的理由。把这些理由转化成一个具有前提和结论的清晰论证。用“如果……那么……”的格式来揭示逻辑。
Stage 3 – Evaluate: Test each premise. Is it factually true? Is it supported by ethical theories such as Utilitarianism or Kantian ethics? Are there hidden assumptions, like ‘nature always tells us what is right’?
阶段三——评估：检验每一个前提。它在事实上是否为真？它是否得到功利主义、康德伦理学等道德理论的支持？是否存在隐藏的前提假设，如“自然总能告诉我们对错”？
Stage 4 – Respond: Weigh counterarguments. Can a different philosophical perspective weaken the original argument? Always finish by stating your own justified position, even if it is tentative.
阶段四——回应：权衡反论证。是否有不同的哲学视角能削弱原论证？始终以清晰地陈述你有理有据的立场收尾，哪怕只是试探性的。

3. Case 1: The Trolley Problem – Moral Philosophy | 案例1：电车难题——道德哲学

A runaway trolley is heading towards five people who will be killed if nothing is done. You can pull a lever to divert the trolley onto a side track, where one person is standing and would be killed instead. Is it morally permissible to pull the lever? (Philippa Foot, 1967)

一辆失控的电车正冲向五个人，如果什么都不做他们将会丧生。你可以扳动道岔，把电车引向侧轨，而侧轨上站着一个人，此人将被撞死。扳动道岔在道德上是可允许的吗？（菲利帕·福特，1967年）

Identifying the issue: The case asks whether an action that deliberately brings about one death to save five lives is morally acceptable. The underlying philosophical tension lies between consequentialist and deontological ethics.

识别议题：该案例询问的是，一个故意造成一人死亡却拯救五条生命的行动在道德上是否可接受。隐含的哲学张力存在于结果论伦理学与义务论伦理学之间。

Reconstructing arguments:
Argument A (Utilitarian): P1: An action is right if it maximises overall happiness. P2: Saving five lives produces more happiness than saving one. C: Therefore, pulling the lever is right.

重构论证：
论证 A（功利主义）：前提 1：如果一项行动能最大化总体幸福，那么它就是正确的。前提 2：拯救五条生命比拯救一条生命产生更多幸福。结论：因此，扳动道岔是正确的。

Argument B (Kantian): P1: One must never use a person merely as a means. P2: Pulling the lever uses the one person as a means to save five. C: Therefore, pulling the lever is morally wrong.

论证 B（康德主义）：前提 1：人决不能被仅仅当作手段来利用。前提 2：扳动道岔是将那一个人当作了拯救五人的手段。结论：因此，扳动道岔是道德上错误的。

Evaluation: You should test the premises. For Argument A, can we really measure happiness across five versus one life? Does the calculation ignore the rights of the individual? For Argument B, does the ‘using as a means’ premise fail if the one person would not have died otherwise? Consider the Doctrine of Double Effect, which distinguishes between intending harm and foreseeing harm.

评价：你应当检验那些前提。对于论证 A，我们真的能量化比较五条命与一条命的幸福吗？这种计算是否忽视了个体权利？对于论证 B，如果侧轨上的人本来并不会死，“当作手段”这一前提是否成立？要考虑双重效应原则，它区分了意图造成伤害与预见伤害。

Use a table to compare the two frameworks clearly.

使用表格来清晰地比较这两个框架。

Criterion	Utilitarianism	Kantian Ethics
Focus	Consequences / happiness	Duty / respect for persons
Rule for the lever	Pull, because 5 > 1 lives saved	Do not pull, because it uses a person as means
Key criticism	Ignores individual rights and justice	Can be too rigid in catastrophe cases

4. Case 2: The Brain in a Vat – Epistemology | 案例2：缸中之脑——知识论

Imagine that while you sleep, an evil scientist removes your brain and places it in a vat of nutrients. The scientist connects your brain to a supercomputer that feeds you exactly the same sensory experiences you are having now. You think you are reading this text, but in reality you are just a brain in a vat. How do you know you are not a brain in a vat? (Adapted from Hilary Putnam)

设想在你睡觉时，一个邪恶的科学家取出了你的大脑，并将其放入一个营养缸中。科学家把你的大脑连到一台超级计算机上，计算机精确地为你输送你此刻正拥有的全部感官经验。你以为你在读这段文字，但事实上你只是一个缸中之脑。你如何知道自己不是一个缸中之脑？（改编自希拉里·普特南）

Identifying the issue: This case challenges our ordinary claims to knowledge. If we cannot rule out the brain-in-a-vat scenario, then perhaps we do not know anything about the external world. This is a radical sceptical challenge.

识别议题：该案例挑战了我们关于知识的寻常主张。如果我们不能排除缸中之脑的可能性，那么我们也许对外部世界一无所知。这是一个彻底的怀疑论挑战。

Reconstructing the sceptical argument:
P1: If I know I have hands, then I know I am not a brain in a vat.
P2: I do not know I am not a brain in a vat.
C: Therefore, I do not know I have hands.

重构怀疑论的论证：
前提 1：如果我知道自己有手，那么我就知道自己不是一个缸中之脑。
前提 2：我不知道自己不是一个缸中之脑。
结论：因此，我不知道自己有手。

Evaluation: Several responses exist. The relevant alternatives theory states that a possibility only undermines knowledge if it is a relevant alternative in the context. In ordinary life, the brain-in-a-vat scenario is not relevant, so my claim ‘I have hands’ still counts as knowledge. Another reply is that the sceptic sets the bar unreasonably high; knowledge does not require absolute certainty. You might also introduce reliabilism: my sense perception reliably indicates hands, so I know.

评价：存在几种回应。相关备择理论主张，仅当一个可能性在特定语境中是一个相关备择时，它才会削弱知识。在日常生活中，缸中之脑的情境不是相关的备择，因此“我有手”的论断依然算作知识。另一种回答是，怀疑论者把标准定得过高，知识并不要求绝对确定性。你还可以引入可靠论：我的感官知觉可靠地指示出手，所以我知道。

When writing your answer, show how the sceptical argument is valid but you can reject premise 2 or weaken the concept of knowledge it assumes.

在写答案时，要展示出怀疑论的论证是有效的，但你可以拒绝前提 2 或削弱它所假定的知识概念。

5. Identifying Fallacies in Arguments | 识别论证中的谬误

Philosophy demands clear reasoning. Often an argument in a case study may sound persuasive because it contains a fallacy. You need to spot these errors and explain why they weaken the reasoning.

哲学要求清晰的推理。案例研究中的论证往往可能因为包含谬误而听起来很有说服力。你需要发现这些错误，并解释它们为何会削弱推理。

Consider this scenario: ‘The head teacher says we must not study philosophy because only confused people waste time on such questions. She is wrong because she has never read any philosophy herself.’ Which fallacy is at play? It is a version of ad hominem—dismissing an argument by attacking the person, not the content. The fact that the head teacher has not read philosophy does not automatically make her claim false.

思考这个场景：“校长说我们不能学习哲学，因为只有糊涂蛋才会把时间浪费在这种问题上。她是错的，因为她自己从未读过任何哲学。”这里有什么谬误在作祟？它是一种人身攻击——通过攻击对方的人格而非内容来驳斥一个论证。校长没有读过哲学这一事实，并不能自动证明她的论断为假。

Common fallacies you should practise recognising include:

你应该练习识别的常见谬误包括：

Straw man: Misrepresenting an opponent’s position to make it easier to refute. ‘Utilitarians just want to use people as calculators.’
稻草人谬误：歪曲对方立场以使其更容易反驳。“功利主义者无非是想把人当计算器使。”
False dilemma: Presenting only two options when more exist. ‘Either we pull the lever or we are murderers.’
假两难谬误：在存在更多选项时只给出两个选项。“要么扳道岔，要么我们是杀人犯。”
Begging the question: The conclusion is assumed in a premise. ‘Lying is always wrong because lies are immoral.’
循环论证：结论被假定在一个前提中。“撒谎永远是错的，因为谎言是不道德的。”

Always name the fallacy and explain how it fails to support the conclusion.

请务必说出谬误的名称，并解释它如何未能支持结论。

6. Using Thought Experiments Effectively | 有效运用思想实验

Philosophers often create imaginary scenarios to test principles. Knowing how to handle a thought experiment in an exam will set your answer apart. When you meet one, ask three questions: (a) What intuition does the scenario aim to provoke? (b) Is the analogy between the scenario and reality strong enough? (c) Could the same intuition be explained by a different principle?

哲学家经常创设虚构情景来检验原则。知道如何在考试中处理一个思想实验，会让你的答案脱颖而出。当你遇到一个时，提出三个问题：(a) 该情景旨在引发什么样的直觉？(b) 这个情景与现实之间的类比是否足够强有力？(c) 同样的直觉能否用另一种原则来解释？

Take Judith Jarvis Thomson’s famous violinist. You wake up to find yourself plugged into a famous violinist who needs your kidneys for nine months to survive. Is it morally obligatory to stay plugged in? The scenario tests the claim that a right to life always outweighs bodily autonomy. You should note how the analogy is limited: pregnancy is not like being kidnapped, and the relationship to a fetus is different from a stranger. Yet the thought experiment helps clarify where we draw the line between compassion and personal rights.

以朱迪思·贾维斯·汤姆森著名的小提琴家思想实验为例。你一觉醒来，发现自己被连到了一位著名小提琴家身上，他需要借用你的肾脏九个月才能存活。在道德上，你有义务保持连接吗？该情景检验了“生命权永远优先于身体自主权”的主张。你应当注意这个类比的局限性：怀孕与绑架不同，与胎儿的关系也不同于陌生人。然而，这个思想实验有助于厘清我们在同情与个人权利之间如何划界。

Your answer should do more than describe the scenario—it should expose the underlying principle and assess the analogy’s strength.

你的答案不应只描述情景，而应揭示其背后原则并评估类比的说服力。

7. Structuring Your Exam Answer | 构建你的考试答案

A clear structure makes your analysis convincing. A widely recommended model is PEEL-X, which stands for Point, Evidence/Example, Explain, Link, and a critical eXtra step for philosophy.

清晰的结构能让你的分析更有说服力。一个被广泛推荐的模式是 PEEL-X，它代表观点、证据/示例、解释、关联，并为哲学增加了一个批判性的额外步骤。

Point: State your claim directly. ‘The trolley dilemma reveals a conflict between utilitarianism and deontological ethics.’
观点：直接陈述你的主张。“电车难题揭示了功利主义与义务论伦理学间的冲突。”
Evidence/Example: Refer to the case detail. ‘In the lever scenario, saving five lives at the cost of one is a utilitarian calculus.’
证据/示例：引用案例的细节。“在扳道岔的场景中，牺牲一人拯救五人是一种功利主义的计算。”
Explain: Analyse why this matters. ‘This matters because it forces us to ask whether numbers alone determine moral rightness.’
解释：分析这为何重要。“这之所以重要，是因为它迫使我们追问，仅仅靠数量能否决定道德上的正确。”
Link: Connect back to the question or to a broader theme. ‘Thus, the problem challenges the assumption that morality is merely about outcomes.’
关联：回扣问题或更宏大的主题。“因此，该问题挑战了道德仅仅关乎后果这一预设。”
eXtra – Counterargument and response: ‘However, a Kantian would argue that the act itself is wrong regardless of outcomes. I find this insufficient because it ignores the moral significance of preventing a greater tragedy.’
额外——反论证与回应：“然而，康德主义者会主张，无论后果如何，该行动本身都是错的。我认为这不够充分，因为它忽视了防止更大悲剧的道德重要性。”

By using this pattern, you ensure your answer shows depth and balance, which examiners reward.

运用这一模式，你能确保答案展现出深度与平衡，这正是考官所欣赏的。

8. Practice Drill with a New Case: The Ring of Gyges | 新案例演练：裘格斯戒指

Read the case from Plato’s Republic: Gyges, a shepherd, finds a ring that makes him invisible. Using this power, he seduces the queen, kills the king, and seizes the throne. Glaucon argues that anyone who could act unjustly without being caught would do so, and therefore justice is only a compromise we obey out of fear of punishment. Is he right?

阅读柏拉图《理想国》中的案例：牧羊人裘格斯发现了一枚能让他隐身的戒指。借助这种力量，他引诱了王后，杀死国王并夺取了王位。格劳孔论证说，任何人如果能不被人发现地行不义之事，就都会这么做，因此正义只是人们因为惧怕惩罚而遵守的一种妥协。他说得对吗？

Now, apply the four-stage analysis on your own, then compare with this model response.

现在，请自己运用四阶段分析法，然后与以下样板答案比较。

Identify: The philosophical issue is the nature of justice—whether it is intrinsically valuable or merely an instrumental good to avoid harm. The central question: Would a truly just person resist the ring?

识别：哲学议题是正义的本质——正义是具有内在价值，还是仅仅作为一种避免伤害的工具性善。核心问题：一个真正正义的人会抵制这枚戒指吗？

Reconstruct: Glaucon’s argument: P1: Humans are naturally self-interested. P2: If there were no consequences, self-interest would lead us to act unjustly. C: Therefore, justice is only practised for fear of external punishment, not for its own sake.

重构：格劳孔的论证：前提1：人类天生是自利的。前提2：如果没有后果，自利会驱使我们行不义之事。结论：因此，人们践行正义仅仅是因为惧怕外在惩罚，而非为了正义本身。

Evaluate: You could challenge premise 1 by citing moral exemplars who behave justly even in private. Additionally, Plato’s response is that a just soul is more harmonious and genuinely happier. Even if invisible, the unjust person would damage their own psychic health. The ring merely reveals our true character, it does not determine it.

评价：你可以引用即便在私底下也行为端正的道德楷模来挑战前提1。此外，柏拉图的回应是，正义的灵魂更和谐，也真正地更幸福。即使隐身，不义者也会损害自身的灵魂健康。戒指只是暴露了我们的真实品格，而非决定它。

Respond: While Glaucon powerfully describes how many people would behave, he fails to prove that everyone would. The ring of Gyges thus becomes a test of moral integrity, not proof that justice is empty. My own view is that a society built only on fear of punishment would be fragile, and that genuine justice has an internal reward.

回应：虽然格劳孔强有力地描述了许多人会如何行动，但他并未证明所有人都会如此。裘格斯戒指因此成为对道德完整性的测试，而不是正义空洞无物的证明。我自己的看法是，一个仅建基于惩罚恐惧之上的社会将是脆弱的，而真正的正义具有内在的奖赏。

Practising with such cases builds the ability to think like a philosopher—moving beyond description to critical evaluation.

通过这样的案例演练，你将培养出像哲学家一样思考的能力——从描述走向批判性评价。
