📚 Philosophy Case Studies: Practical Exercises | 哲学案例分析实战演练
In Year 9 Philosophy, learning to apply theories to concrete scenarios is an essential skill. Case studies allow you to practise identifying philosophical problems, evaluating arguments, and constructing balanced responses. This article presents ten classic philosophical puzzles and dilemmas, each followed by guided analysis. By working through these examples, you will sharpen your ability to think critically about ethics, knowledge, reality, and logic — exactly the skills assessed in CIE examinations.
在九年级哲学课程中，学会将理论应用于具体情境是一项关键能力。案例分析帮助你练习识别哲学问题、评估论证并构建平衡的回应。本文呈现十个经典哲学谜题与困境，每个都配有引导式分析。通过钻研这些例子，你将提升对伦理、知识、实在与逻辑的批判性思维能力——这正是剑桥国际考评所看重的技能。
1. Why Case Studies in Philosophy? | 为什么需要哲学案例分析？
Philosophy is not just about learning what famous thinkers said. It is about doing philosophy — asking questions, examining assumptions, and building arguments. Case studies bridge the gap between abstract theory and real-life problems. They force you to apply principles such as 'the greatest happiness for the greatest number' or 'treat people as ends, never merely as means' to situations with competing intuitions. When you analyse a case, you practise clarifying the dilemma, identifying stakeholders, weighing consequences, and considering alternative viewpoints. This mirrors the structure of a strong exam essay: introduction, analysis, counter-argument, and conclusion.
哲学不仅仅是学习著名思想家说了什么。它是“做哲学”——提出问题、审视假设并建构论证。案例研究弥合了抽象理论与现实问题之间的鸿沟。它们迫使你把“最大多数人的最大幸福”或“始终把人当作目的而不仅仅是手段”等原则应用于存在直觉冲突的情境。当你分析一个案例时，你练习厘清困境、识别利益相关方、权衡后果并考虑不同观点。这恰好对应了一篇优秀考试论文的结构：引言、分析、反论证和结论。
2. The Trolley Problem: Utilitarianism vs. Deontology | 电车难题：功利主义与道义论
A runaway trolley is heading toward five workers who cannot escape. You can pull a lever to switch the trolley onto a side track, where one worker stands. Is it morally permissible to sacrifice one to save five? In a variant, you push a large man off a bridge to stop the trolley. Most people say pulling the lever is acceptable, but pushing the man is not. This challenges utilitarianism, which judges actions solely by outcomes. Deontologists, following Kant, argue that using a person as a mere means is always wrong, regardless of consequences. The case sharpens the distinction between what we calculate as best and what we feel is right.
一辆失控的电车冲向五名无法逃脱的工人。你可以拉动拉杆让电车转向侧轨，那里站着一名工人。牺牲一人救五人，在道德上是否允许？在另一个版本中，你需要把一个胖子推下桥来阻止电车。多数人认为拉动拉杆可以接受，但推人则不行。这对以结果来判断行为的功利主义提出了挑战。遵循康德的道义论者认为，仅仅把人当作手段永远是错误的，无论后果如何。这个案例凸显了“算计出的最优”与“感觉上正确”之间的区别。
3. The Ship of Theseus: The Puzzle of Identity | 忒修斯之船：同一性之谜
According to legend, the Athenians preserved Theseus' ship by replacing each rotting plank over time. Eventually, every original part was replaced. Is the restored ship the same Ship of Theseus? What if someone gathered all the discarded planks and reassembled them into a second ship? Which one would be the real Ship of Theseus? This case explores the problem of identity over time. It challenges the idea that an object is just the sum of its material parts. Philosophers propose different criteria: spatiotemporal continuity, causal history, or psychological connectedness (for persons). The puzzle remains a classic introduction to metaphysics.
根据传说，雅典人通过逐年更换腐朽的木板来保存忒修斯之船。最终，所有原始部件都被替换。修复后的船还是原来的忒修斯之船吗？如果另有人收集所有废弃木板，重新组装成第二艘船呢？哪一艘才是真正的忒修斯之船？这个案例探讨了历时同一性问题。它挑战了“物体仅仅是其物质部件的总和”的观念。哲学家提出了不同标准：时空连续性、因果历史或（对人格而言）心理联结。这一谜题至今仍是形而上学的经典入门。
4. Descartes' Evil Demon: Radical Scepticism | 笛卡尔的邪恶恶魔：彻底怀疑论
Imagine a powerful, malicious demon that deceives you into believing there is an external world, other people, and even your own body — while in reality, all your experiences are illusions. Descartes used this thought experiment to doubt everything that can be doubted. His goal was to find a foundation of certainty. He concluded that even if the demon deceives him, he must exist to be deceived: 'I think, therefore I am.' The Evil Demon case highlights the difficulty of justifying our most basic beliefs about reality. It pushes you to ask: what, if anything, can we know for sure?
想象一个强大的邪恶恶魔，它欺骗你相信存在外部世界、他人乃至自己的身体——而实际上，所有经验都是幻觉。笛卡儿用这个思想实验来怀疑一切可怀疑之物。他的目标是找到确定性的根基。他得出结论：即使恶魔在欺骗他，他也必须存在才能被欺骗：“我思故我在”。邪恶恶魔案例凸显了证明我们对实在最基本信念的困难。它促使你追问：如果有的话，什么才是我们能够确切知道的？
5. The Sorites Paradox: Vagueness in Concepts | 谷堆悖论：概念的模糊性
Start with a single grain of sand. It is not a heap. Add one grain; still not a heap. If you repeat this process, at what point does a heap appear? There seems to be no sharp boundary — yet, eventually, we call it a heap. The Sorites Paradox shows that many everyday concepts (heap, bald, tall) are vague. If you cannot identify the precise number that makes a heap, can you claim to truly know what a heap is? This puzzle has implications for logic, law, and language. It suggests that our categories may be more fluid than we think.
从一粒沙开始。它不是谷堆。加一粒，仍不是谷堆。不断重复这一过程，究竟在哪一刻才出现了谷堆？似乎没有一个明确的界限——但最终我们却称之为谷堆。谷堆悖论表明，许多日常概念（谷堆、秃顶、高）是模糊的。如果你找不出构成谷堆的精确数量，还能宣称真正知道什么是谷堆吗？这个谜题对逻辑、法律和语言都有影响，暗示我们的分类可能比想象中更具流动性。
6. The Prisoner's Dilemma: Reason and Morality | 囚徒困境：理性与道德
Two suspects are arrested separately. If both stay silent, each serves 1 year. If one betrays the other, the betrayer goes free and the silenced partner serves 10 years. If both betray, each serves 5 years. From a purely self-interested viewpoint, betrayal is rational regardless of the other's choice. Yet, mutual cooperation yields a better collective outcome. The Prisoner's Dilemma illustrates the tension between individual rationality and collective welfare. It is widely used in ethics, political philosophy, and game theory to explain why trust, contracts, and moral norms are necessary for social cooperation.
两名嫌犯被分开逮捕。若两人都保持沉默，各判1年。若一人背叛，背叛者释放，沉默者判10年。若两人都背叛，各判5年。从纯粹自利的视角看，无论对方如何选择，背叛都是理性的。然而，互相合作却产生更好的集体结果。囚徒困境揭示了个人理性与集体福祉之间的紧张。它被广泛应用于伦理学、政治哲学和博弈论，用以解释信任、契约和道德规范为何对社会合作不可或缺。
7. Free Will and the Libet Experiment | 自由意志与李贝特实验
In the 1980s, neuroscientist Benjamin Libet asked participants to flex their wrist at a moment of their choosing while monitoring brain activity. He found that a 'readiness potential' in the brain occurred about 500 milliseconds before the conscious decision to act. This seems to suggest that the brain decides before 'we' do, challenging free will. Does this mean our choices are determined by unconscious brain processes? Critics argue that the readiness potential may only reflect preparation, not decision. The case invites deeper reflection on whether we are genuinely the authors of our actions.
20世纪80年代，神经科学家本杰明·李贝特要求被试在自觉选定的时刻弯曲手腕，同时监测其脑活动。他发现大脑出现“准备电位”约比有意识的行动决定早500毫秒。这似乎表明大脑先于“我们”做了决定，对自由意志构成挑战。这是否意味着我们的选择由无意识脑过程决定？批评者认为，准备电位也许只反映预备状态而非决定。这个案例促使我们深入反思：我们是否真的是自身行为的创作者？
8. Pascal's Wager: Belief and Rationality | 帕斯卡的赌注：信仰与理性
Blaise Pascal argued that believing in God is the rational choice even without proof. If God exists, believers gain infinite reward (heaven) and non-believers face infinite punishment. If God does not exist, both lose nothing significant. Therefore, the expected value of belief outweighs non-belief. Critics point out the 'many gods' objection: which God should we believe in? And can genuine belief be forced by calculation? Pascal's Wager raises profound questions about the relationship between faith, reason, and pragmatic justification.
帕斯卡论证说，即便没有证明，信仰上帝也是理性的选择。如果上帝存在，信徒获得无限奖赏（天堂），不信者面临无限惩罚。如果上帝不存在，两者都无重大损失。因此，信仰的期望价值超过不信仰。批评者提出“多神”反驳：我们该信哪个神？并且，真诚的信仰能被计算所强迫吗？帕斯卡的赌注引发了关于信仰、理性与实用辩护之间关系的深刻问题。
9. The Problem of Other Minds | 他心问题
You know you have thoughts, feelings, and consciousness. But how do you know that other people do? You observe their behaviour, hear their words, and infer mental states by analogy with yourself. Yet, this inference could be mistaken: perhaps others are sophisticated robots or philosophical zombies with no inner experience. The Problem of Other Minds challenges the justification for our everyday certainty that others are minded. It connects to solipsism — the idea that only one's own mind is sure to exist. This case forces you to examine the limits of empathy and evidence.
你知道自己拥有思想、情感和意识。但你如何知道他人也有？你观察他们的行为，聆听他们的话语，通过与自身的类比来推断其心理状态。然而，这种推断可能是错误的：也许他人是没有内在体验的精密机器人或哲学僵尸。他心问题挑战了我们日常确信他人有心智的理据。它与唯我论——即唯有自己的心灵确凿存在——相关联。这个案例迫使你审视同理心与证据的限度。
10. Moral Relativism: The Samurai and the Merchant | 道德相对主义：武士与商人
Imagine a 17th-century Japanese samurai who believes it is honourable to test a new sword by cutting down a commoner. A contemporary European merchant, witnessing this, is horrified. Is the samurai's action simply wrong, or is moral truth relative to culture? This case tests moral relativism — the view that right and wrong vary across societies. If relativism is true, we lose the ability to criticise harmful cultural practices. Yet, absolutism must explain how we can know universal moral truths. Examining such cross-cultural clashes helps you evaluate whether there are ethical standards that transcend tradition.
想象一位17世纪的日本武士，他认为用新刀斩杀平民来试刀是荣誉之举。一位同时代的欧洲商人目睹此事，感到惊骇。武士的行为就是错误的，还是道德真理相对于文化而定？这个案例检验了道德相对主义——对错因社会而异的观点。如果相对主义成立，我们便丧失了批评有害文化习俗的能力。然而，绝对主义则必须解释我们如何能认识普遍的道德真理。审视此类跨文化冲突，有助于你评估是否存在超越传统的伦理标准。
11. Socrates' Choice: Civil Disobedience | 苏格拉底的选择：公民不服从
Socrates was sentenced to death by the Athenian court for corrupting the youth and impiety. His friends arranged an escape, but Socrates refused. He argued that having lived under Athens' laws, he had a duty to accept their verdict, even when unjust. Would escaping undermine the rule of law? This case raises the question of when, if ever, it is right to break the law. It contrasts with later thinkers like Martin Luther King, who endorsed civil disobedience against unjust laws. Analysing Socrates' decision pushes you to balance respect for social contracts against the demands of justice.
苏格拉底被雅典法庭以腐蚀青年和不敬神判处死刑。他的朋友安排了越狱，但苏格拉底拒绝了。他论证说，既然生活在雅典法律之下，就有义务接受其判决，即便不公正。逃跑是否会损害法治？这个案例提出了何时（如果可能的话）违法才正当的问题。它与后来的马丁·路德·金等思想家形成对比，后者赞同以公民不服从对抗不公正法律。分析苏格拉底的决定，促使你平衡对社会契约的尊重与正义的要求。
12. Tips for Analysing Philosophical Cases | 分析哲学案例的技巧
Start by clearly stating the central philosophical question the case raises. Identify the conflicting intuitions or principles. Then, map possible positions: what would a utilitarian say? A deontologist? A virtue ethicist? Use technical vocabulary such as 'premise', 'validity', 'counter-example', and 'thought experiment'. Always consider objections and replies. Remember, a strong analysis does not merely describe but evaluates — it shows why one view might be more defensible than another. Practise writing short, structured paragraphs that weave together the case details with abstract theories. Over time, you will develop a fluent, critical style that examiners reward.
首先，清晰陈述案例引发的核心哲学问题。识别冲突的直觉或原则。然后，绘制出可能的立场：功利主义者会怎么说？道义论者呢？德性伦理学家呢？使用专业词汇，如“前提”、“有效性”、“反例”和“思想实验”。始终考虑反对意见与回应。记住，强有力的分析不只是描述，而是评价——它展示为何一种观点可能比另一种更具辩护力。练习写作简短、结构清晰的段落，把案例细节与抽象理论交织在一起。久而久之，你会形成流畅而富有批判性的文风，这正是考官所青睐的。
