Philosophy is the love of wisdom. At KS3 level, you begin to ask big questions about knowledge, reality, values, and the mind. This article brings together the essential topics you will encounter in the CAIE Lower Secondary Philosophy curriculum, offering clear English explanations paired with Chinese translations to strengthen your bilingual learning.
哲学即爱智慧。在 KS3 阶段，你将开始追问关于知识、实在、价值和心灵的大问题。本文汇集了你在 CAIE 初中哲学课程中会遇到的各个核心主题，用英文解释搭配中文翻译，帮助你扎实掌握双语概念。
1. What is Philosophy? | 什么是哲学？
Philosophy is the activity of questioning the most basic assumptions we have about the world and ourselves. It does not simply accept common beliefs but examines them through reason and argument. The word itself comes from the Greek ‘philo-‘ (love) and ‘sophia’ (wisdom).
哲学是一种对我们关于世界和自身的最基本假设提出质疑的活动。它并不简单地接受流行信念，而是通过理性和论证来审视它们。这个词本身源于希腊语 philo-（爱）和 sophia（智慧）。
Philosophy is divided into several branches: metaphysics (the nature of reality), epistemology (the theory of knowledge), ethics (moral values), logic (correct reasoning), and aesthetics (the nature of beauty). At KS3, you learn to think like a philosopher by asking ‘Why?’ and ‘What do you mean?’ in every discussion.
哲学分为几个分支：形而上学（实在的本质）、认识论（知识理论）、伦理学（道德价值）、逻辑（正确推理）和美学（美的本质）。在 KS3，你通过在每个讨论中追问“为什么？”和“你是什么意思？”来学习像哲学家一样思考。
2. Logic and Arguments | 逻辑与论证
An argument in philosophy is not a quarrel; it is a set of statements where some (premises) are given to support another statement (the conclusion). A good argument is one where if the premises are true, the conclusion must be true. This is called validity.
哲学中的论证并非争吵，而是一组陈述，其中某些陈述（前提）用来支持另一个陈述（结论）。一个好的论证是指，如果前提为真，结论必定为真。这被称为有效性。
There are two main types of reasoning: deductive and inductive. Deductive arguments aim to guarantee the conclusion; inductive arguments make the conclusion probable based on evidence. Recognizing fallacies, such as attacking the person instead of the idea (ad hominem), is a key skill.
推理主要有两种：演绎和归纳。演绎论证旨在保证结论；归纳论证则基于证据让结论成为可能。识别谬误，比如攻击人而非观点（人身攻击），是一项关键技能。
3. Epistemology: What is Knowledge? | 认识论：什么是知识？
Epistemology asks: What does it mean to know something? The traditional definition is justified true belief (JTB). You know that P if you believe P, P is true, and you have good reasons (justification) for your belief.
认识论追问：知道某件事意味着什么？传统定义是经过辩护的真信念（JTB）。你知道 P，仅当你相信 P，P 为真，并且你有充分的理由（辩护）支持你的信念。
However, Gettier cases challenge this definition by showing situations where someone has a justified true belief but still seems to lack knowledge due to luck. This teaches us that knowledge is more complex than it first appears. We also explore the sources of knowledge: perception, reason, testimony, and memory.
然而，盖梯尔问题挑战了这一界定，它展示了某些情况下某人拥有经过辩护的真信念，却因运气而似乎仍然缺乏知识。这告诉我们知识比乍看起来更复杂。我们还会探讨知识的来源：知觉、理性、证言和记忆。
4. Ethics: How Should We Live? | 伦理学：我们应该如何生活？
Ethics, or moral philosophy, investigates what is right and wrong, good and bad. Three major approaches are often studied: consequentialism, deontology, and virtue ethics. Consequentialism (such as utilitarianism) judges actions by their outcomes, aiming to maximise happiness.
伦理学或道德哲学，研究什么是正确与错误、善与恶。通常学习三大进路：后果论、义务论和美德伦理。后果论（如功利主义）根据行为的结果来判断，旨在最大化幸福。
Deontology, associated with Immanuel Kant, argues that some actions are right or wrong in themselves, regardless of consequences, based on duties and rules. Virtue ethics, from Aristotle, focuses on the character of the moral agent and the cultivation of virtues like courage, honesty, and compassion.
义务论，与伊曼努尔·康德相关，主张某些行为本身就是对的或错的，不论其后果如何，基于义务与规则。美德伦理，源自亚里士多德，关注道德主体的品格以及勇气、诚实、同情等美德的培养。
5. Metaphysics: The Ultimate Nature of Things | 形而上学：事物的终极本性
Metaphysics deals with questions about what exists and what it is like. It considers concepts such as time, space, causation, identity, and the difference between appearance and reality. For instance, is the world made of one substance or many?
形而上学处理关于存在什么及其样态的问题。它考察诸如时间、空间、因果性、同一性以及表象与实在之间的差异等概念。例如，世界是由一种实体构成，还是多种实体？
We also examine the problem of personal identity: what makes you the same person over time? Is it your body, your memories, or a continuous soul? These questions help us understand the world beyond the physical sciences.
我们还会考察人格同一性问题：是什么让你在时间中成为同一个人？是你的身体、你的记忆，还是一个连续的灵魂？这些问题帮助我们理解超越物理科学的世界。
6. Philosophy of Mind | 心灵哲学
Philosophy of mind explores the relationship between the mind and the body. Dualism, famously defended by Rene Descartes, holds that the mind is a non-physical substance distinct from the brain. Physicalism, on the other hand, claims that mental states are entirely physical brain states.
心灵哲学探索心灵与身体的关系。二元论，由勒内·笛卡尔著名地辩护，认为心灵是一种区别于大脑的非物理实体。物理主义则主张，心理状态完全就是物理的大脑状态。
We ask whether computers could ever have genuine thoughts and feelings (the problem of artificial intelligence and consciousness). These discussions introduce the ‘hard problem’ of consciousness: why do physical processes produce subjective experience?
我们会问，计算机是否可能拥有真正的思想和感受（人工智能与意识问题）。这些讨论引出了意识的“困难问题”：物理过程为什么会产生主观体验？
7. Political Philosophy: Justice and the State | 政治哲学：正义与国家
Political philosophy examines how society should be organised, what makes a government legitimate, and what rights individuals possess. Key concepts include justice, liberty, equality, and authority.
政治哲学考察社会应如何组织、什么使政府合法，以及个人拥有什么权利。核心概念包括正义、自由、平等和权威。
One influential idea is the social contract, proposed by thinkers like Thomas Hobbes, John Locke, and Jean-Jacques Rousseau. It suggests that individuals agree to give up some freedoms in exchange for security and order. We also discuss distributive justice: how should goods and resources be shared in a society? Utilitarian, egalitarian, and libertarian answers are weighed.
一个影响深远的思想是社会契约，由托马斯·霍布斯、约翰·洛克和让-雅克·卢梭等思想家提出。它主张个人同意放弃某些自由以换取安全与秩序。我们还会讨论分配正义：社会中的物品和资源应如何分享？功利主义、平等主义和自由至上主义的回答会被权衡。
8. Free Will and Determinism | 自由意志与决定论
Do we have free will, or are all our actions determined by prior causes? Determinism claims that every event, including human choices, is the inevitable result of previous conditions and laws of nature. If determinism is true, can we be held morally responsible for our actions?
我们拥有自由意志吗，还是我们所有的行为都由先在的原因所决定？决定论声称，每一事件，包括人类的选择，都是先前条件和自然规律的必然结果。如果决定论为真，我们还能为自己的行为承担道德责任吗？
Compatibilism argues that free will and determinism can co-exist: free actions are those caused by our own desires and intentions, even if those are themselves determined. Libertarianism (in philosophy) insists on genuine free choice that is not determined. This debate shapes our views on punishment, praise, and blame.
相容论主张自由意志和决定论可以共存：自由行为是由我们自己的欲望和意图引发的，即使这些自身是被决定的。自由意志论（哲学意义上的）主张存在不被决定的真正自由选择。这场争论塑造着我们对惩罚、赞扬和责备的看法。
9. Aesthetics and the Philosophy of Art | 美学与艺术哲学
Aesthetics asks what makes something beautiful or artistically valuable. Is beauty a quality of the object, or is it in the eye of the beholder? Philosophers debate whether aesthetic judgments can be objective or are purely subjective.
美学追问：是什么让某物成为美的或有艺术价值？美是物体的一种性质，还是仅仅存在于观看者的眼中？哲学家们争论审美判断能否是客观的，还是纯粹主观的。
We also consider the definition of art. Can a pile of bricks be art? The institutional theory suggests that something is art if the artworld (galleries, critics, artists) designates it as such. Other theories emphasize expression, significant form, or the arousal of emotion. These ideas encourage you to think critically about the art you encounter every day.
我们还会思考艺术的定义。一堆砖头可以是艺术吗？体制理论认为，如果艺术界（画廊、批评家、艺术家）指定某物为艺术，那它就是艺术。其他理论强调表现、有意义的形式或情感的唤起。这些观点鼓励你对每天遇到的艺术进行批判性思考。
10. Philosophy of Religion | 宗教哲学
Philosophy of religion applies rational inquiry to religious beliefs. It examines arguments for the existence of God, such as the cosmological argument (a first cause of the universe), the teleological argument (design in nature), and the ontological argument (the concept of a perfect being).
宗教哲学将理性探究运用于宗教信仰。它考察上帝存在的论证，例如宇宙论论证（宇宙的第一因）、目的论论证（自然中的设计）和本体论论证（完美存在的概念）。
The problem of evil is a major challenge: if God is all-powerful and all-good, why is there suffering? Responses include the free will defence and the idea that evil is necessary for soul-making. The relationship between faith and reason is also explored: can religious belief be rational without evidence?
恶的问题是重大挑战：如果上帝是全能和全善的，为什么还有苦难？回应包括自由意志辩护以及恶是灵魂塑造所必需的观点。信仰与理性的关系也被探讨：宗教信仰可以在没有证据的情况下仍然是理性的吗？
11. Key Thinkers in the History of Philosophy | 哲学史上的关键思想家
Familiarity with great philosophers helps you grasp the historical development of ideas. Socrates (c. 470–399 BCE) taught through questioning and is known for the statement ‘the unexamined life is not worth living’. His pupil Plato (c. 428–348 BCE) developed the theory of Forms, arguing that the physical world is a shadow of a higher reality.
熟悉伟大的哲学家有助于你把握思想的历史发展。苏格拉底（约公元前 470–399 年）通过提问进行教导，以“未经审视的人生不值得过”闻名。他的学生柏拉图（约公元前 428–348 年）发展了理型论，认为物理世界是更高实在的摹本。
Aristotle (384–322 BCE), Plato’s student, emphasised empirical observation and the virtues. In the modern era, Descartes’ dualism and Kant’s deontology remain central. Don’t just memorise names; explore how their arguments respond to each other over centuries.
亚里士多德（公元前 384–322 年），柏拉图的学生，强调经验观察和美德。在近代，笛卡尔的二元论和康德的义务论仍然是核心。不要仅仅记住名字；要探索他们的论证如何在几个世纪中相互回应。
12. Doing Philosophy: Critical Thinking and Dialogue | 做哲学：批判性思维与对话
Ultimately, philosophy is not just a body of knowledge but a way of thinking. It requires clarity in defining terms, careful analysis of arguments, and the courage to question received opinions. In your KS3 course, you will participate in debates, write reflective pieces, and evaluate ethical dilemmas.
归根结底，哲学不仅是一套知识，更是一种思维方式。它要求定义术语清晰、仔细分析论证，并有勇气质疑公认的意见。在你的 KS3 课程中，你将参与辩论、撰写反思文章，并评估伦理困境。
A good philosopher listens to other viewpoints and revises their own position in light of better reasons. Remember that philosophical progress is often made by sharpening the questions rather than finding final answers. Keep asking ‘What if?’ and ‘How do we know?’ and you will be doing philosophy.
一个好的哲学家会倾听他人的观点，并根据更好的理由修正自己的立场。记住，哲学的进步往往在于让问题变得更尖锐，而非找到最终答案。不断追问“如果……会怎样？”和“我们怎么知道？”，你就是在做哲学了。
