1. What is Philosophy? | 什么是哲学？
Philosophy comes from the Greek words 'philo' (love) and 'sophia' (wisdom). It is not about memorising facts, but about asking fundamental questions and seeking reasoned answers. Philosophy examines the foundations of science, art, morality, religion, and human life.
哲学一词来自希腊语“philo”（爱）和“sophia”（智慧）。它并非关于记忆事实，而是提出根本性问题并寻求有理由的答案。哲学审视科学、艺术、道德、宗教和人类生活的基础。
Unlike experimental sciences, philosophers often use thought experiments and logical reasoning to investigate concepts such as justice, truth, the self, and the mind. The aim is not just to find an answer, but to understand why one answer is better than another.
与实验科学不同，哲学家常常使用思想实验和逻辑推理来研究正义、真理、自我和心灵等概念。目的不仅是找到一个答案，更是要理解为什么某个答案更好。
2. Branches of Philosophy | 哲学的主要分支
Philosophy is traditionally divided into several main branches. Metaphysics asks what reality is: Do we have free will? What is time? Epistemology explores knowledge and belief: How do we know what we know? Can we trust our memory?
哲学传统上分为几个主要分支。形而上学追问实在是什么：我们有自由意志吗？时间是什么？认识论探究知识与信念：我们如何知道我们所知道的？我们可以相信自己的记忆吗？
Ethics is the study of right and wrong, good and bad, and how we ought to live. Logic is the study of correct reasoning, teaching us to distinguish good arguments from bad ones. Aesthetics deals with beauty, art, and taste.
伦理学是对对错、好坏以及我们应当如何生活的探究。逻辑学是对正确推理的研究，教我们区分好的论证与坏的论证。美学处理美、艺术和品味的问题。
All these branches are connected. For example, to answer ethical questions, we often need to know what human nature is (metaphysics) and how we can justify our moral beliefs (epistemology).
所有这些分支都是相互连接的。例如，要回答伦理学问题，我们常常需要知道人性是什么（形而上学）以及我们如何能证成自己的道德信念（认识论）。
3. Socrates and the Art of Questioning | 苏格拉底与提问的艺术
Socrates (c. 470–399 BCE) is one of the most famous Greek philosophers. He did not write any books himself; we know him through the works of his student Plato. Socrates believed that wisdom begins when we admit our own ignorance – 'I know that I know nothing'.
苏格拉底（约公元前470–399年）是最著名的希腊哲学家之一。他自己没有写下任何著作；我们通过他学生柏拉图的著作了解他。苏格拉底相信，智慧始于承认自己的无知——“我只知道我一无所知”。
He developed the Socratic method: asking a series of questions to help a person examine their own beliefs and definitions. This critical dialogue exposes contradictions and leads to deeper understanding. It is still used in law schools and classrooms today.
他发展了苏格拉底方法：通过提出一系列问题，帮助一个人审视自己的信念和定义。这种批判性对话揭示矛盾，导向更深刻的理解。至今此法仍用于法学院和课堂中。
4. Plato's Theory of Forms | 柏拉图的理型论
Plato (c. 428–348 BCE), a student of Socrates, proposed the Theory of Forms. He argued that the physical world we see is only a shadow of a higher, truer reality. In that reality exist the 'Forms' or 'Ideas' – perfect, unchanging patterns of things like justice, beauty, and a circle.
柏拉图的（约公元前428–348年），苏格拉底的学生，提出了理型论。他论证说，我们所见的物理世界只是一个更高的、更真实的实体的影子。在那个实在中存在着“理型”或“理念”——那些如正义、美和圆等事物的完美、不变的范型。
Imagine a perfect triangle. In the physical world we can draw many triangles, but none are absolutely perfect. Plato would say the perfect triangle exists as a Form, and physical triangles merely 'participate' in this Form. The famous Allegory of the Cave illustrates this idea: prisoners mistake shadows on a wall for reality until one escapes and sees the sun.
想象一个完美的三角形。在物理世界中我们可以画出许多三角形，但没有一个是绝对完美的。柏拉图会说完美的三角形作为理型存在，而物理的三角形只是“分有”了这一理型。著名的洞穴寓言解释了这一思想：囚犯们误把墙上的影子当作真实，直到一人逃脱并看见太阳。
5. Aristotle and Practical Wisdom | 亚里士多德与实践智慧
Aristotle (384–322 BCE) was a student of Plato but developed his own ideas. He rejected the separate world of Forms and believed that we can understand reality by observing the natural world. He emphasised empirical evidence and classification.
亚里士多德（公元前384–322年）是柏拉图的学生，但发展了自己的思想。他拒斥分离的理型世界，相信我们可以通过观察自然世界来理解实在。他强调经验证据和分类。
In ethics, Aristotle argued that the good life is a life of virtue ('arete'). Virtues are character traits such as courage, honesty, and generosity, developed through practice and habit. The goal is 'eudaimonia' – human flourishing or living well, not just a feeling of happiness.
在伦理学中，亚里士多德主张好的生活是德性的生活。德性是如勇敢、诚实和慷慨等品格特质，通过实践和习惯养成。目标是“eudaimonia”——人的繁盛或活得好，而不仅仅是快乐的感觉。
He also introduced the Golden Mean: virtue lies between two extremes. For example, courage is the mean between cowardice and recklessness. This practical wisdom ('phronesis') helps us decide the right action in each situation.
他还提出了中庸之道：德性处于两个极端之间。例如，勇敢是怯懦与鲁莽之间的中道。这种实践智慧（“phronesis”）帮助我们在每种情境中决定正确的行为。
6. Introduction to Logic: Arguments, Premises, and Conclusions | 逻辑入门：论证、前提与结论
Logic is the study of valid reasoning. An argument consists of one or more premises (supporting statements) and a conclusion (the statement they aim to prove). A good argument is one where the premises truly support the conclusion.
逻辑是对有效推理的研究。一个论证由一个或多个前提（支持性陈述）和一个结论（它们旨在证明的陈述）组成。一个好的论证是前提真正支持结论的论证。
Consider a simple deductive argument:
Premise 1: All humans are mortal.
Premise 2: Socrates is a human.
Conclusion: Therefore, Socrates is mortal.
If the premises are true and the form is valid, the conclusion must be true. This is a valid deductive argument. Inductive arguments, by contrast, provide probable support but are not airtight – for instance, 'The sun has risen every day so far, so it will rise tomorrow.'
如果前提为真且形式有效，结论必然为真。这是一个有效的演绎论证。相反，归纳论证提供可能的支持但并非绝对严密——例如，“迄今为止太阳每天都升起，所以明天太阳也会升起。”
7. Fallacies: Common Mistakes in Reasoning | 谬误：推理中的常见错误
A fallacy is an error in reasoning that makes an argument unsound. Recognising fallacies is a key skill in philosophy. One common fallacy is 'ad hominem' (against the person): attacking the person making the argument instead of the argument itself. For example, 'You cannot trust her view on the environment because she is not a scientist.'
谬误是推理中的错误，使得论证不健全。辨识谬误是哲学中的一项关键技能。一种常见的谬误是“人身攻击”：攻击提出论证的人，而不是论证本身。例如，“你不能相信她关于环境的观点，因为她不是科学家。”
Another is the 'straw man' fallacy: misrepresenting someone's argument to make it easier to attack. 'You say we should reduce spending on military. You must want our country to be defenceless.' The original argument was simply about reducing, not eliminating, spending.
另一种是“稻草人”谬误：歪曲某人的论点，使其更易被攻击。“你说我们应该削减军事开支。你一定是想让我们的国家毫无防御。”原论点仅仅是削减，而非取消开支。
The 'false dilemma' presents only two options when more exist: 'Either you support this policy, or you do not care about the poor.' Being aware of these pitfalls helps us think more rationally.
“虚假两难”仅呈现两个选项，而实际上存在更多选择：“要么你支持这项政策，要么你不在乎穷人。”意识到这些陷阱有助于我们更理性地思考。
8. Introduction to Ethics | 伦理学入门
Ethics is the philosophical study of morality, asking questions like: What makes an action right? Is morality universal or relative? Are there objective moral truths? Two major ethical theories often introduced at this level are consequentialism and deontology.
伦理学是对道德的哲学研究，追问：什么使得一个行为是对的？道德是普遍的还是相对的？是否存在客观的道德真理？在此阶段常常介绍的两个主要伦理学理论是后果论和义务论。
Consequentialism (especially utilitarianism, associated with Jeremy Bentham and John Stuart Mill) judges actions by their outcomes. The right action is the one that produces the greatest happiness for the greatest number. As Bentham put it, we should aim at 'the greatest good for the greatest number'.
后果论（尤其是与边沁和密尔相关的功利主义）根据结果来判断行为。正确的行为是能为最大多数人产生最大幸福的行为。正如边沁所言，我们应追求“最大多数人的最大善”。
Deontology (associated with Immanuel Kant) argues that some actions are right or wrong in themselves, regardless of consequences. Kant's categorical imperative states that we should act only according to rules that could become universal laws, and never treat people merely as means, but always as ends in themselves.
义务论（与康德相关）主张有些行为本身就是对的或错的，不论后果如何。康德的绝对命令声明，我们只应按照能够成为普遍律的准则来行动，并且永远不要只把人当作手段，而要始终同时当作目的自身。
9. The Trolley Problem | 电车难题
The Trolley Problem is a famous thought experiment in ethics. Imagine a runaway trolley is heading down a track where five people are tied up. You can pull a lever and divert the trolley onto a side track, but one person is tied there. Would you pull the lever?
电车难题是伦理学中一个著名的思想实验。想象一辆失控的电车正冲向一条有五个人被绑住的轨道。你可以拉杆将电车转向一条侧轨，但那里绑着一个人。你会拉杆吗？
This dilemma tests the difference between consequentialist and deontological thinking. A utilitarian would likely pull the lever, because saving five lives at the cost of one produces greater overall happiness. A deontologist might refuse, arguing that deliberately causing one person's death, even to save five, is wrong in itself.
这一两难处境检验了后果论和义务论思维之间的差异。功利主义者很可能拉杆，因为以牺牲一人为代价拯救五人能产生更大的总体幸福。义务论者可能拒绝，认为故意造成一个人的死亡本身是错误的，即使是为了拯救五个人。
Variations of the problem challenge our intuitions: What if the one person is a close friend? What if the five are old and the one is a child? The Trolley Problem helps us clarify our moral principles.
这个难题的变式挑战我们的直觉：如果那一个人是你的密友呢？如果五人是年长者而那一个是儿童呢？电车难题帮助我们澄清自己的道德原则。
10. The Ship of Theseus | 忒修斯之船
The Ship of Theseus is a thought experiment about identity and change. According to legend, the ship of the hero Theseus was preserved by the Athenians. Over time, as each plank rotted, it was replaced with a new one, until eventually no original part remained. Is it still the same ship?
忒修斯之船是一个关于同一性与变化的思想实验。据传说，英雄忒修斯的船被雅典人保存下来。随着时间流逝，每块木板腐烂后都被换成新的，直到最后没有一个原来的部件留下。这还是同一条船吗？
A further twist: what if you took all the removed old planks and reassembled them into a ship? Which one is the real Ship of Theseus – the continuously repaired one, or the reconstructed original? This puzzle raises deep questions about what makes an object the same over time.
进一步的变化：如果你把所有换下来的旧木板重新组装成一条船呢？哪一艘是真正的忒修斯之船——不断修换的这一艘，还是由原部件重建的那一艘？这个难题引发了关于什么使得一个物体在时间中保持同一的深层问题。
These ideas apply to personal identity too. You change physically as you grow, yet you remain the same person. What is the 'self' that persists through change? Philosophers still debate this.
这些想法也适用于个人同一性。你在成长中身体发生了变化，但你仍是同一个人。那个历变而存的“自我”是什么？哲学家们至今仍在争论。
11. Can We Trust Our Senses? | 我们能相信自己的感官吗？
Our senses – sight, hearing, touch, taste, and smell – give us information about the world. But can they be trusted completely? Epistemology asks whether sensory experience can give us true knowledge. Optical illusions, for example, show that our senses can be deceived.
我们的感官——视觉、听觉、触觉、味觉和嗅觉——给予我们关于世界的信息。但它们能完全被信任吗？认识论追问感官经验是否能给我们真实的知识。例如，视错觉表明我们的感官可能被欺骗。
The ancient sceptic Pyrrho doubted that we can know anything for certain. René Descartes imagined an 'evil demon' who could trick us into believing a false world – a forerunner of the modern 'brain in a vat' thought experiment. If we cannot be absolutely sure that we are not dreaming, can we trust any knowledge based on the senses?
古代怀疑论者皮浪怀疑我们能否确实地知道任何事。勒内·笛卡尔想象了一个“邪恶的恶魔”，它可能欺骗我们相信一个虚假的世界——这是现代“缸中之脑”思想实验的前身。如果我们不能绝对确信自己不在做梦，我们还能信任基于感官的任何知识吗？
Most philosophers today argue that while absolute certainty might be impossible, we can still have good reasons to trust our senses most of the time, and science helps to correct perceptual errors.
今天多数哲学家认为，虽然绝对的确定性也许不可能，但我们大多数时候依然有充分的理由信任感官，而科学有助于纠正知觉错误。
12. What Makes a Good Life? | 什么是美好的生活？
Philosophers have long asked what it means to live a good life. Different traditions give different answers. For hedonists like Epicurus, a good life is one filled with pleasure and free from pain. But not just reckless pleasure; Epicurus valued friendship, reflection, and simple pleasures.
哲学家们长久以来追问，什么意味着活得好。不同传统给出了不同的答案。对像伊壁鸠鲁这样的享乐主义者来说，好的生活是充满快乐且免于痛苦的生活。但不只是放纵的快乐；伊壁鸠鲁珍视友谊、沉思和简单的快乐。
Aristotle, as we saw, gave a virtue-based answer: the good life is a life of activity in accordance with virtue, using reason well, and developing one's full potential. Modern thinkers have added ideas about meaning, relationships, and authenticity.
如我们所见，亚里士多德给出了基于德性的回答：好的生活是一种合乎德性的活动的生活，善于运用理性，并发展一个人的全部潜能。现代思想家还增添了关于意义、关系和真实性的观念。
Students are encouraged to reflect on their own values. Is the good life mainly about happiness, achievement, helping others, or something else? There is no single 'Cambridge answer', but the process of reasoning about it is itself a philosophical exercise.
我们鼓励学生反思自己的价值观。好的生活主要是关于快乐、成就、帮助他人，还是别的什么？并没有单一的“剑桥答案”，但对这个问题展开推理的过程本身就是一种哲学练习。
