Year 7 Cambridge Philosophy: Case Study Practical Exercises | Year 7 剑桥哲学：案例分析实战演练

📚 Year 7 Cambridge Philosophy: Case Study Practical Exercises | Year 7 剑桥哲学：案例分析实战演练

Philosophy is not only about memorising famous thinkers and their ideas—it is primarily about learning to think clearly, critically, and carefully about difficult questions. In the Cambridge Year 7 Philosophy course, you are often asked to apply philosophical concepts to real or imagined situations, known as case studies. This article takes you through a series of famous thought experiments and scenarios, showing you how to analyse them, identify the key philosophical issues, and build well-reasoned arguments. Each case study is presented in the same structured way you would use in an exam or classroom discussion: a description of the scenario, the central philosophical problem it raises, some distinct viewpoints, and practice questions for you to try. By working through these practical exercises, you will strengthen your ability to think like a philosopher and to express your ideas with precision and confidence.

哲学不仅仅是记住著名的思想家及其观点——更重要的是学会清晰、批判性地、仔细地思考困难的问题。在剑桥 Year 7 哲学课程中，你经常被要求将哲学概念应用到真实或想象的情境中，这些情境被称为案例研究。本文将带你浏览一系列著名的思想实验和场景，向你展示如何分析它们、识别关键的哲学问题，并构建论证充分的推理。每个案例研究都以你在考试或课堂讨论中使用的同一种结构化方式呈现：对场景的描述、它所提出的核心哲学问题、一些不同的观点，以及供你练习的思考题。通过完成这些实践练习，你将增强像哲学家一样思考的能力，并精准、自信地表达自己的想法。

1. Introduction to Philosophical Case Studies | 哲学案例研究简介

A philosophical case study is a short, vivid story designed to highlight a deep conceptual puzzle. These stories, often called thought experiments, allow us to test our intuitions and explore the consequences of different moral, metaphysical, or epistemological theories. In your Cambridge course, you will encounter case studies to sharpen your skills in identifying assumptions, evaluating arguments, and constructing balanced responses. Always begin by reading the scenario carefully and asking: ‘What exactly is the problem here?’ and ‘What concepts are being challenged?’

哲学案例研究是一个简短而生动的故事，旨在突显一个深刻的概念难题。这些故事常被称为思想实验，能让我们检验自己的直觉，并探索不同道德、形而上学或认识论理论的后果。在你的剑桥课程中，你将遇到案例研究，以磨练你识别假设、评估论证以及构建平衡回应的技能。始终要从仔细阅读场景开始，并问自己：“这里的问题到底是什么？”以及“哪些概念受到了挑战？”

2. The Trolley Problem | 电车难题

A runaway trolley is speeding down a track towards five workers who cannot escape. You are standing next to a lever. If you pull it, the trolley will switch to a side track, where one worker is trapped. Is it morally right to pull the lever? This case challenges our moral reasoning: is it always better to save more lives, or do we have a duty not to intentionally cause harm, even when the outcome is better? Utilitarian thinkers argue that we should maximise overall well-being, so pulling the lever is required. Deontologists, following Immanuel Kant, might argue that using a person merely as a means to save others violates a fundamental moral rule, making the action impermissible. Discussing this case helps you explore the tension between consequences and moral duties.

一辆失控的电车正沿着轨道冲向五名无法逃脱的工人。你站在一个拉杆旁边。如果你拉下拉杆，电车将转到另一条侧轨，那里有一名工人被困。拉下拉杆在道德上是否正确？这个案例挑战了我们的道德推理：总是挽救更多的生命更好吗，还是我们有责任不故意造成伤害，即使结果更好？功利主义者认为我们应该最大化整体福祉，因此拉下拉杆是必须的。义务论者，遵循康德的观点，可能会争辩说，仅仅利用一个人作为拯救他人的手段违反了一条基本的道德规则，使得该行为不被允许。讨论这个案例有助于你探索后果与道德义务之间的紧张关系。

3. The Ship of Theseus | 特修斯之船

Over many years, every plank and part of the famous Ship of Theseus is gradually replaced as it wears out. Eventually, not a single original piece remains. Meanwhile, the removed old parts are gathered and reassembled into a second ship. Which one is the true Ship of Theseus? This puzzle raises profound questions about identity and persistence through change. If an object changes all its parts, is it still the same object? One view emphasises spatio-temporal continuity: the ship that remained in use in the harbour, despite having new parts, is the original. Another view focuses on the material composition: the reassembled ship is made of the original planks, so it has a stronger claim. Philosophers use this case to discuss personal identity too—are you the same person after all your cells have been replaced over time? Exploring this case sharpens your thinking about what makes something what it is.

经过许多年，著名的特修斯之船上的每一块木板和每一个部件都因磨损而被逐渐替换。最终原来的部件一块都不剩了。同时，那些被拆下来的旧部件被收集起来，重新组装成了第二艘船。哪一艘才是真正的特修斯之船？这个难题提出了关于同一性和经变化而持存的深刻问题。如果一个物体改变了它所有的部件，它还是同一个物体吗？一种观点强调时空连续性：那艘一直在港口使用着的船，尽管有了新部件，仍是原来的那艘。另一种观点关注物质构成：重新组装的那艘船是由原始的木板做成的，因此它有更充分的理由声称是原物。哲学家也用这个案例来讨论人格同一性——在你的细胞随时间全部被替换后，你还是同一个人吗？探究这个案例能增强你对是什么让某物成为它自身的思考。

4. The Ring of Gyges | 巨吉斯的戒指

In Plato’s ‘Republic’, Glaucon tells the story of a shepherd who finds a ring that makes him invisible. Using this power, the shepherd seduces the queen, kills the king, and takes over the kingdom. Glaucon asks: if you had such a ring, would you still act justly? This case challenges the idea that people value justice for its own sake, rather than for the rewards it brings. If we could get away with wrongdoing without any consequences, would we bother being moral? Many argue that a truly just person would resist temptation, because justice is intrinsically valuable. Others suspect that without social pressure and fear of punishment, most people would act selfishly. When you analyse this case, think about the relationship between self-interest, reputation, and moral motivation. Are we just only because we are watched?

在柏拉图的《理想国》中，格劳孔讲述了一个牧羊人发现一枚能让他隐身的戒指的故事。利用这种能力，牧羊人引诱了王后，杀死了国王，夺取了王国。格劳孔问道：如果你有这样一枚戒指，你还会行为正义吗？这个案例挑战了人们重视正义本身而非它所带来的回报这一观念。如果我们可以做坏事而不承担任何后果，我们还会费心保持道德吗？许多人认为，一个真正正义的人会抵制诱惑，因为正义具有内在价值。另一些人则怀疑，没有社会压力和对惩罚的恐惧，大多数人会自私地行事。当你分析这个案例时，思考一下自利、名誉和道德动机之间的关系。我们仅仅是因为被人注视才保持正义吗？

5. The Brain in a Vat | 缸中之脑

Imagine that your brain has been removed from your body and placed in a vat of nutrients, connected to a supercomputer that simulates reality perfectly. All your experiences—reading this text, feeling the chair beneath you—are just electrical signals fed into your brain. Could you ever prove that you are not a brain in a vat? This modern version of Descartes’ evil demon argument raises sceptical questions about the external world. If all our evidence comes through our senses, and those senses could be deceived, then any belief about the world might be false. Some philosophers argue that the idea of a ‘brain in a vat’ is self-refuting, because the words we use would refer to simulated objects, not real ones. Nonetheless, this case forces you to examine the limits of knowledge and the justification of our most basic beliefs.

想象一下，你的大脑被从身体中取出，放进一个充满营养液的缸中，连接到一台完美模拟现实的超级计算机上。你所有的体验——正在阅读这段文字、感觉身下的椅子——都只是输入你大脑的电信号。你能否证明自己不是一个缸中之脑？这个笛卡尔恶魔论证的现代版本提出了关于外部世界的怀疑论问题。如果我们所有的证据都来自我们的感官，而这些感官可能被欺骗，那么任何关于世界的信念都可能是假的。一些哲学家认为，“缸中之脑”这个观念是自我反驳的，因为我们使用的词语将指涉模拟的对象，而非真实的物体。尽管如此，这个案例迫使你审视知识的界限以及我们最根本信念的理据。

6. The Prisoner’s Dilemma | 囚徒困境

Two prisoners are interrogated separately. If both stay silent, they each serve a short sentence. If one betrays the other while the other stays silent, the betrayer goes free and the silent prisoner serves a long sentence. If both betray, they both serve medium sentences. Despite mutual silence being the best collective outcome, rational self-interest leads each to betray. This case illustrates the tension between individual rationality and collective benefit, raising questions about cooperation, trust, and the nature of moral behaviour. When applied to real-world issues such as climate change or arms races, the prisoner’s dilemma shows why purely self-interested reasoning can lead to worse outcomes for everyone. Philosophers use this model to explore the conditions under which cooperation can emerge and the role of morality in solving coordination problems.

两名囚犯被分开审讯。如果两人都保持沉默，他们各自服短期刑期。如果一人背叛而另一人沉默，背叛者获释，沉默的囚犯服长期刑期。如果两人都背叛，他们各自服中期刑期。尽管互相沉默是最好的集体结果，但理性的自利却引导每个人去背叛。这个案例说明了个人理性与集体利益之间的紧张关系，提出了关于合作、信任和道德行为本质的问题。当应用于气候变化或军备竞赛等现实世界问题时，囚徒困境揭示了为何纯粹自利的推理会导致对所有人都更糟糕的结果。哲学家利用这个模型来探索合作得以出现的条件，以及道德在解决协调问题中的作用。

7. The Experience Machine | 体验机（诺齐克）

Robert Nozick asks us to imagine a machine that can give you any experience you desire. You would float in a tank, with electrodes connected to your brain, and live a life filled with perfect happiness, achievements, and relationships—all while believing the experiences are real. Once plugged in, you would not know the difference. Would you plug in? If you hesitate, you reveal that we value more than just the felt quality of our experiences. Many people say no, because they want to actually do things, not just have the feeling of doing them; they want to be a certain kind of person, in genuine relationships with others and reality. This thought experiment is a powerful tool for evaluating hedonism—the view that pleasure is the only intrinsic good.

罗伯特·诺齐克让我们想象一台能给你任何你渴望的体验的机器。你将漂浮在一个水箱中，电极连接着你的大脑，过上充满完美幸福、成就和人际关系的生活——同时相信这些体验都是真实的。一旦连接上，你便不会知道有什么区别。你会连接上吗？如果你犹豫了，就表明我们重视的不仅仅是体验的感受质量。许多人选择不连接，因为他们想要真正地做事情，而不只是有做事情的感觉；他们希望成为某种特定的人，与他人和现实保持真实的关系。这个思想实验是评价享乐主义——即快乐是唯一内在善的观点——的有力工具。

8. The Veil of Ignorance | 无知之幕（罗尔斯）

John Rawls proposed a thought experiment for designing a fair society. Imagine you are in an ‘original position’ behind a veil of ignorance, where you do not know your own talents, class, gender, ethnicity, or conception of the good. From this position, you must choose the principles of justice that will govern your society. Rawls argues that rational people behind the veil would choose two principles: equal basic liberties for all, and that social and economic inequalities are allowed only if they benefit the least advantaged. This case invites you to consider what fairness truly requires: would you support a principle that could leave you badly off if you turned out to be the worst-off member of society? Use this to discuss issues like progressive taxation, equal opportunity, and the justification of social safety nets.

约翰·罗尔斯提出了一个设计公平社会的思想实验。想象你处于“原初状态”中，站在无知之幕背后，你不知道自己的天赋、阶级、性别、种族或善的观念。从这个位置出发，你必须选择将治理你的社会的正义原则。罗尔斯论证道，幕后的理性人将会选择两个原则：所有人享有平等的基本自由，以及社会经济的不平等只有在它们有利于最不利者时才是被允许的。这个案例让你思考公平真正要求的是什么：如果你最终成为社会中最不利的成员，你会支持一项可能让你处境糟糕的原则吗？利用这一点来讨论诸如累进税制、机会平等以及社会安全网的合理性问题。

9. The Sorites Paradox | 秃头悖论

The Sorites paradox begins with a single grain of sand, which clearly is not a heap. Adding one grain at a time, it seems absurd to say there is a precise number of grains that turns a non-heap into a heap. Yet eventually, after many additions, we have what anyone would call a heap. This paradox exposes the problem of vagueness in our language: many concepts, like ‘heap’, ‘bald’, or ‘tall’, have fuzzy boundaries. Philosophical analysis of this case leads to deeper questions about logic, truth, and the nature of concepts. Some philosophers reject classical bivalent logic for such cases, while others argue that linguistic rules simply fail to assign a sharp cutoff. For Year 7 students, engaging with this puzzle sharpens awareness of how language shapes philosophical problems.

秃头悖论或谷堆悖论始于一粒沙子，它显然不是一个谷堆。一次添加一粒沙子，似乎任何精确的粒数将非谷堆变成谷堆都是荒谬的。然而，在许多次添加之后，我们有了任何人都会称为谷堆的东西。这个悖论揭露了我们语言中的模糊性问题：许多概念，如“谷堆”、“秃头”或“高”，都有着模糊的边界。对这个案例的哲学分析引出了关于逻辑、真理和概念本质的更深入问题。一些哲学家因此拒绝在这种情形中使用古典的二值逻辑，而另一些哲学家则认为语言规则根本就没有指定一个清晰的截断点。对于 Year 7 学生来说，探究这个谜题可以增强对语言如何塑造哲学问题的意识。

10. The Chinese Room | 中文屋（塞尔）

Imagine a person who does not understand Chinese sits in a room with a large book of rules. When Chinese characters are passed under the door, the person looks up the correct responses in the book and passes back appropriate Chinese characters. To someone outside, it appears the room understands Chinese. John Searle used this scenario to argue against strong artificial intelligence: a computer program might manipulate symbols according to formal rules without any genuine understanding. The person in the room is like a computer running a program—syntax without semantics. This case is valuable for exploring the nature of mind, consciousness, and the difference between simulating thought and actually thinking. It encourages you to ask: what does it really mean to ‘understand’ something?

想象一个完全不懂中文的人坐在一间屋里，身边有一本巨大的规则手册。当中文字符从门缝下递进来时，这个人查书找到正确的回应，并递出相应的中文字符。对屋外的人来说，这间屋子似乎懂中文。约翰·塞尔用这个场景来反驳强人工智能：计算机程序可能按照形式规则操纵符号，却没有任何真正的理解。屋里的人就像运行程序的电脑——有句法而无语义。这个案例对于探索心灵、意识的本性以及模拟思维与实际思考之间的区别非常有价值。它鼓励你发问：“理解”某事物到底意味着什么？

11. Applying Case Studies to Exam Questions | 将案例应用于考试问题

When you meet a case study in a Cambridge assessment, approach it step by step. First, identify the fundamental concept at stake: is it about morality, personal identity, knowledge, or justice? Then, explain the philosophical problem the scenario raises, using clear terminology. Always offer at least two contrasting perspectives, and support each with reasons. For example, if asked whether you would pull the lever in the trolley problem, you should present the utilitarian case for pulling and the deontological case against pulling, then evaluate which reasoning you find more convincing and why. Avoid simply describing the case; your job is to analyse and argue. Practise writing short paragraphs using the format: ‘One could argue that… because… On the other hand… In my view…’ This structure will help you produce balanced and well-supported responses.

当你在剑桥评估中遇到一个案例研究时，要一步一步地处理。首先，确定所涉及的基本概念：它是关于道德、人格同一性、知识还是正义？然后，用清晰的术语解释这个场景提出的哲学问题。总是提供至少两种对照的观点，并为每一种提供理由。例如，如果被问到你是否会拉动电车难题中的拉杆，你应该提出拉杆的功利主义论证和不拉杆的义务论论证，然后评估哪一种推理你更信服，为什么。避免仅仅描述案例；你的任务是分析和论证。练习使用以下格式写简短的段落：“有人可能会论证说……因为……另一方面……在我看来……”这种结构将帮助你写出平衡且论据充分的回答。

12. Conclusion and Tips for Revision | 总结与复习技巧

Mastering philosophical case studies requires regular practice and curiosity. Create a revision chart for each case study with the headings: Scenario, Central Puzzle, Viewpoint A, Viewpoint B, My Evaluation. Discuss cases with classmates to hear new perspectives and strengthen your reasoning. When revising, challenge yourself to connect cases: how does the Experience Machine relate to the Ring of Gyges? Both ask whether certain experiences or powers make a good life, forcing you to reflect on what truly matters. By treating each case as a playground for ideas, you will become more confident in tackling unseen scenarios and constructing original arguments. Remember, in philosophy, the quality of your reasoning is more important than simply having the ‘right answer’.

掌握哲学案例研究需要定期练习和好奇心。为每个案例研究制作一张复习表，标题为：场景、核心谜题、观点 A、观点 B、我的评价。与同学讨论案例，听取新的观点，强化你的推理。复习时，挑战自己将案例联系起来：体验机与巨吉斯的戒指有何关联？两者都追问某种体验或力量是否构成美好生活，迫使你反思什么才是真正重要的。把每个案例都当作思想的游乐场，你将更有信心处理陌生的场景并构建原创的论证。请记住，在哲学中，你推理的质量比简单地获得“正确答案”更重要。
