1. What is Philosophy? The Love of Wisdom | 什么是哲学？对智慧的热爱
Philosophy comes from the Greek words 'philo' (love) and 'sophia' (wisdom). It is the activity of seeking wisdom by examining fundamental questions about existence, knowledge, values, reason, and language. Unlike subjects that depend purely on experiments or memorisation, philosophy challenges us to think critically about the assumptions we often take for granted.
哲学一词源于希腊语 'philo'（爱）与 'sophia'（智慧），是通过审视关于存在、知识、价值、理性与语言的根本问题来寻求智慧的活动。不同于单纯依赖实验或记忆的学科，哲学要求我们批判性地反思那些常被视为理所当然的假设。
Philosophy is not just a collection of old ideas; it is a method of inquiry. It trains you to ask precise questions, recognise hidden beliefs, and evaluate arguments. In Year 9, you will begin using these skills to explore topics like ethics, personal identity, and the nature of knowledge. A good starting habit is to ask 'Why?' and 'What do I mean by that?' whenever you encounter a strong claim.
哲学并非只是一堆古老思想，而是一种探究方法。它训练你提出精确的问题、识别隐藏的信念并评估论证。在九年级，你将开始运用这些技能探索伦理学、人格同一性和知识的本质等课题。一个好习惯是，每当遇到一个强有力的主张时，就问自己“为什么？”以及“我这么说是什么意思？”
2. The Art of Questioning: Socrates and Critical Inquiry | 提问的艺术：苏格拉底与批判性探究
Socrates, one of the most influential philosophers, claimed that the unexamined life is not worth living. He used a method of persistent questioning—now called Socratic questioning—to help people uncover contradictions in their own thinking. Instead of simply giving answers, he would ask, for instance, 'What is justice?' and then probe each proposed definition until its weaknesses appeared.
苏格拉底是最有影响力的哲学家之一，他宣称未经审视的人生是不值得过的。他运用一种持续提问的方法——现在被称为苏格拉底式提问法——帮助人们发现自己思维中的矛盾。他不是简单地给出答案，而是问“什么是正义？”之类的问题，然后对每个提出的定义加以探究，直到暴露出其中的弱点。
In your summer preparation, you can practise Socratic questioning by picking a simple concept, such as courage or friendship, and trying to define it. Then test your definition against tricky cases. For example, if courage means 'doing something despite fear', does a soldier who blindly follows orders count as courageous? What about someone who acts out of anger? This process sharpens your philosophical instincts.
在暑期预习中，你可以挑选一个简单概念（如勇气或友谊）尝试定义它，然后通过刁钻的案例来检验自己的定义，从而练习苏格拉底式提问。例如，如果勇气是指“尽管害怕仍去做某事”，那么一个盲目服从命令的士兵算得上勇敢吗？出于愤怒而行动的人呢？这个过程能磨砺你的哲学直觉。
3. Thought Experiments: Exploring Big Ideas | 思想实验：探索宏大思想
Philosophers often use thought experiments—imaginary scenarios that isolate a key concept or moral dilemma. They allow us to test ideas without needing a laboratory. The Trolley Problem, for instance, asks whether you would switch a runaway trolley onto a track where it would kill one person instead of five. Your response reveals deeper beliefs about ethics, consequences, and duties.
哲学家经常使用思想实验——通过虚构的情景来孤立关键概念或道德两难。它让我们无需实验室就能检验想法。例如，电车难题询问你是否愿意将失控的电车转到另一条轨道上，从而轧死一个人而非五个人。你的反应将揭示你关于伦理、后果与责任更深层的信念。
Another famous thought experiment is the Ship of Theseus, which challenges our understanding of identity. If every plank of a ship is gradually replaced, is it still the same ship? If the old planks are reassembled, which ship is the original? These puzzles train you to examine concepts like sameness and change without relying on vague intuition.
另一个著名的思想实验是忒修斯之船，它挑战我们对同一性的理解。如果一艘船的每块木板都被逐一替换，它还是原来的那艘船吗？如果把旧木板重新组装起来，哪一艘才是原船？这些谜题训练你检视相同与变化等概念，而不是依赖模糊的直觉。
4. Ethics: How Should We Live? | 伦理学：我们应当如何生活？
Ethics, or moral philosophy, investigates how we ought to act and what makes actions right or wrong. In Year 9, you will likely encounter three major frameworks: utilitarianism, deontology, and virtue ethics. Understanding these early will give you a huge advantage.
伦理学（或称道德哲学）探究我们应该如何行动，以及是什么使得行为对错。在九年级，你很可能会接触到三大理论框架：功利主义、义务论和德性伦理。提前理解它们将让你占得先机。
Utilitarianism, associated with Jeremy Bentham and John Stuart Mill, holds that the right action is the one that maximises overall happiness. Deontology, tied to Immanuel Kant, argues that certain duties are absolute—lying is always wrong, even to save a life. Virtue ethics, inspired by Aristotle, focuses on the character of the moral agent and asks what a virtuous person would do.
与杰里米·边沁和约翰·斯图尔特·密尔相关的功利主义认为，正确的行为就是能最大限度地提升总体幸福的行为。与伊曼努尔·康德相关的义务论则主张，某些责任是绝对的——说谎永远是错的，即便为了救命。受亚里士多德启发的德性伦理则关注道德主体的品格，探讨有德之人会怎么做。
| Utilitarianism: The morally right action is the one that produces the greatest good for the greatest number. |
| 功利主义：道德上正确的行为，就是能为最大多数人带来最大善的行为。 |
| Deontology: Certain moral rules must be followed regardless of consequences, because they stem from rational duty. |
| 义务论：某些道德规则必须被遵守，无论后果如何，因为它们源于理性义务。 |
| Virtue Ethics: Right action flows from a good character; we should cultivate virtues like honesty, courage, and compassion. |
| 德性伦理：正确的行为源自良好品格；我们应该培养诚实、勇敢和同情等美德。 |
Use these theories to examine real-life cases. When you read a news story about a difficult moral choice, ask: what would a utilitarian recommend? What would a deontologist say? This habit bridges theory and everyday life.
用这些理论来审视真实案例。当你读到一篇有关艰难道德选择的新闻时，问问自己：功利主义者会给出什么建议？义务论者又会怎么说？这个习惯能将理论与日常生活连接起来。
5. Knowledge and Belief: Can We Trust Our Senses? | 知识与信念：我们能相信感官吗？
Epistemology is the branch of philosophy concerned with knowledge and justified belief. It asks questions such as: what does it mean to know something? Can we trust our senses? A traditional definition states that knowledge is justified true belief. But even this definition faces challenges, as shown in Gettier cases where a person has a justified true belief that still does not seem to count as knowledge.
认识论是哲学中关涉知识与确证信念的分支。它提出的问题包括：知道某件事意味着什么？我们能相信自己的感官吗？一个传统定义是，知识即确证的真信念。但就连这个定义也面临挑战，比如在葛梯尔案例中，一个人拥有确证的真信念，却似乎仍不算是知识。
During summer, try a simple exercise: close your eyes and describe the room purely from memory. How accurate are you? Consider optical illusions. They reveal that our senses can be systematically deceived. Philosophers like Descartes even imagined an evil demon that could trick us about the entire external world. These sceptical scenarios help you understand why justification matters.
暑假里，不妨试试这个简单练习：闭上眼睛，仅凭记忆描述房间。你的描述有多准确？再想想视错觉。它们表明我们的感官可能被系统性地欺骗。像笛卡尔这样的哲学家甚至设想了一个能让我们对整个外部世界产生错觉的恶魔。这些怀疑论情境能帮助你理解为何确证如此重要。
6. Identity and Change: The Ship of Theseus | 同一性与变化：忒修斯之船
We touched on the Ship of Theseus earlier; now let us explore it more deeply. This puzzle asks whether an object that has had all its components replaced remains the same object. Applied to personal identity, the question becomes: are you the same person you were five years ago, given that your cells, memories, and personality have changed? Philosophers offer different answers.
前面我们简单提到了忒修斯之船，现在让我们深入探讨。这个谜题问的是：一个所有部件都被替换过的物体，是否还是同一个物体？应用到人格同一性上，问题就变成：鉴于你的细胞、记忆和性格都已发生变化，五年前的你和现在的你还是同一个人吗？哲学家们给出了不同的答案。
The psychological continuity theory suggests that you remain the same person if there is an unbroken chain of memories and mental states. The biological approach insists that being the same organism is enough. Meanwhile, some thinkers argue that identity is merely a convenient label we assign. You can try reconstructing the Ship of Theseus yourself using everyday objects, like a worn-out football that has been patched and re-patched several times.
心理连续性理论认为，只要存在一条不间断的记忆和心理状态链条，你就还是同一个人。生物学进路则坚持，只要是同一个有机体便已足够。与此同时，一些思想家主张同一性不过是我们赋予的方便标签。你可以用日常物品自己重构忒修斯之船，比如一个经过多次修补的破旧足球。
7. Introduction to Logic: Valid Arguments and Fallacies | 逻辑导论：有效论证与谬误
Logic gives philosophy its structure. An argument in philosophy is not a shouting match but a series of statements (premises) that lead to a conclusion. A valid argument is one where, if the premises are true, the conclusion must be true. Soundness requires both validity and true premises. Knowing the difference will help you evaluate any philosophical text.
逻辑为哲学提供了结构。哲学中的论证不是吵架，而是一系列陈述（前提）导向结论。一个有效论证是指，如果前提为真，结论必然为真。而可靠性则要求有效且所有前提为真。了解这一区别将有助于你评估任何哲学文本。
Common forms include modus ponens and modus tollens. An example of modus ponens:
If P then Q. P. Therefore, Q. (P → Q, P ⊢ Q)
常见形式包括肯定前件式和否定后件式。肯定前件式的例子：
如果 P 则 Q。P 成立。因此，Q 成立。(P → Q, P ⊢ Q)
Equally important is recognising informal fallacies. An ad hominem fallacy attacks the person instead of the argument. A straw man misrepresents an opponent's view to make it easier to defeat. A false dilemma suggests only two options exist when there are more. Spotting these tricks will make you a sharper reader and debater.
识别非形式谬误同样重要。人身攻击谬误攻击的是人而非论证。稻草人谬误曲解对方观点以便更容易驳倒。虚假两难则暗示只有两种选择，而实际上存在更多选项。能发现这些花招会让你成为更敏锐的读者和辩论者。
8. Reading Philosophy: How to Engage with Texts | 哲学阅读：如何与文本互动
Reading philosophy is different from reading a novel or a textbook. You must slow down, re-read, and constantly question the author's reasoning. Start by identifying the main thesis—what the writer wants to prove. Then map the arguments that support it. Look for definitions of key terms, because philosophical disagreements often turn on how words are used.
阅读哲学不同于阅读小说或教科书。你必须放慢速度、反复阅读，并不断质疑作者的推理。首先找出主要论点——作者想要证明什么。然后梳理支持这一论点的论证。留意关键术语的定义，因为哲学分歧往往取决于词语的用法。
A practical summer exercise: select a short philosophical passage (you can find simplified versions of Plato's dialogues online). Read it once without taking notes, then try to summarise the argument in your own words. Check if you missed any crucial steps. Highlight words like 'necessary', 'sufficient', 'therefore', and 'thus'—they signal the logical structure.
一个实用的暑期练习：选择一段简短的哲学文本（你可以在网上找到柏拉图对话的简化版）。先不做笔记读一遍，然后尝试用自己的话总结论证。检查是否遗漏了任何关键步骤。高亮“必要”、“充分”、“因此”、“由此”等词——它们标志着逻辑结构。
9. Writing Philosophy: Building Clear Arguments | 哲学写作：构建清晰论证
Philosophical writing values clarity and precision above all. In Year 9, you will be asked to write short essays or paragraphs that present a reasoned position. A strong piece of philosophical writing states a clear thesis, offers reasons for it, considers possible objections, and responds to them. It avoids emotional language and sweeping generalisations.
哲学写作最看重清晰与精确。在九年级，你会被要求撰写短文或段落来陈述一个有理由支撑的立场。一篇优秀的哲学文章会提出清晰的论点，提供理由，考虑可能的反对意见并作出回应。它会避免情绪化语言和笼统概括。
Practise this summer by picking a simple ethical question, such as 'Is it ever right to lie?' Write one paragraph defending a 'yes' or 'no' answer, using at least one ethical theory from Section 4. Then write another paragraph that imagines how someone with the opposite view might reply. This dialectical approach is at the heart of philosophy.
这个暑假，你可以挑选一个简单的伦理问题，例如“说谎是否可能正确？”，然后运用第四节中的至少一种伦理理论，写一段话为“是”或“否”辩护。接着再写一段话，设想持相反观点的人会如何回应。这种辩证方法正是哲学的核心。
10. Your Summer Study Plan and Recommended Activities | 暑期学习计划与推荐活动
To make the most of your summer, set aside around 30 minutes three times a week. Keep a 'Philosophy Journal' where you record questions, thought experiments, and reflections. Watch animated philosophy videos on topics like the Trolley Problem or Plato's Cave. Read a beginner-friendly philosophy book, such as 'Sophie's World' or 'The Philosophy Book: Big Ideas Simply Explained'.
为了充分利用暑假，请每周留出三次、每次约三十分钟的时间。准备一本“哲学日记”，记录你的问题、思想实验和反思。观看有关电车难题或柏拉图洞穴之类的动画哲学视频。阅读一本入门友好的哲学书，例如《苏菲的世界》或《哲学百科：简明图解大观念》。
Find a debate partner—a friend or family member—and discuss one philosophical question each week. Listen carefully to their reasons before responding. This builds charitable reading habits. Additionally, practise summarising arguments from news editorials or opinion pieces, identifying premises and conclusions.
找一个辩论伙伴——朋友或家人——每周讨论一个哲学问题。在回应之前仔细倾听对方的理由。这能培养宽容的阅读习惯。此外，练习从新闻社论或评论文章中总结论证，识别前提和结论。
11. Common Mistakes and How to Avoid Them | 常见错误与避免方法
Many beginners assume philosophy is about winning arguments or stating opinions loudly. In truth, philosophy values careful listening and intellectual humility. Another common error is confusing correlation with causation—just because two things happen together does not mean one causes the other. Watch out for this in everyday reasoning.
许多初学者误以为哲学就是赢得辩论或大声陈述观点。事实上，哲学重视仔细倾听和智识上的谦逊。另一个常见错误是混淆相关与因果——两件事同时发生并不意味着一件导致了另一件。在日常推理中要警惕这一点。
Students also tend to rely too heavily on dictionary definitions. In philosophy, concepts are contested, and part of the work is exploring those disputes. Rather than just quoting a dictionary, examine how a word functions in different arguments. Finally, avoid the temptation to dismiss a view simply because it feels strange. Seek to understand before you criticise.
学生也容易过度依赖词典定义。在哲学中，概念本身就是有争议的，而探讨这些争议正是哲学工作的一部分。与其仅仅引用词典，不如审视一个词在不同论证中如何发挥作用。最后，要抵制因为某种观点感觉怪异就予以否定的诱惑。在批评之前先力求理解。
12. Looking Ahead: Year 9 Curriculum Preview | 展望未来：九年级课程预览
During Year 9, you are likely to study units on morality and society, personal identity, the nature of reality, and perhaps an introduction to political philosophy. You will also begin to learn structured academic discussion techniques, such as formal debates and Socratic seminars. The skills you develop now—questioning, argument analysis, writing clarity—will directly transfer to these activities.
在九年级，你很可能会学习道德与社会、人格同一性、实在的本质等单元，或许还有政治哲学导论。你还会开始学习结构化的学术讨论技巧，例如正式辩论和苏格拉底式研讨会。你现在发展的提问、论证分析和写作清晰度等技能将直接迁移到这些活动中。
Assessment in Cambridge Philosophy often includes short-answer questions, structured essays, and evaluation of given scenarios. You will need to demonstrate not only knowledge of theories but also the ability to apply them and evaluate their strengths and weaknesses. Your summer notebook can become a valuable reference when you encounter these tasks.
剑桥哲学的评估通常包括简答题、结构化论文和对给定情境的评价。你不仅需要展示对理论的了解，还要能够应用它们并评估其优缺点。当你遇到这些任务时，你的暑期笔记本将成为宝贵的参考资料。
Approach the year with curiosity, patience, and a willingness to be confused—that confusion is often the first step toward genuine understanding. Philosophy is a journey, not a destination, and you are now well equipped to begin.
带着好奇、耐心和甘于困惑的心态迎接这一年——这种困惑往往是走向真正理解的第一步。哲学是一趟旅程而非终点，而你现在已装备齐全，可以出发了。
