1. What is Philosophy? | 什么是哲学？
Philosophy, from the Greek ‘philo-sophia’ (love of wisdom), is the rational investigation of fundamental questions about existence, knowledge, and morality. Unlike empirical sciences, it often relies on logical analysis and conceptual clarity rather than experiments.
哲学源自希腊语 ‘philo-sophia’（爱智慧），是对存在、知识和道德等基本问题的理性探究。与经验科学不同，哲学通常依赖逻辑分析和概念清晰度，而非实验。
The main branches of philosophy relevant to IGCSE include epistemology (theory of knowledge), metaphysics (nature of reality), ethics (moral principles), and philosophy of religion. Developing critical thinking and constructing coherent arguments are central skills.
与 IGCSE 相关的哲学主要分支包括认识论（知识论）、形而上学（现实本质）、伦理学（道德原则）和宗教哲学。培养批判性思维和构建连贯的论证是核心技能。
2. Epistemology: The Tripartite Theory of Knowledge | 认识论：知识的三元理论
Epistemology asks: what does it mean to know something? The traditional analysis defines knowledge as justified true belief (JTB). A person S knows proposition P if and only if: (1) P is true, (2) S believes that P, and (3) S is justified in believing P.
认识论追问：知道某事意味着什么？传统分析将知识定义为确证的真信念（JTB）。一个人 S 知道命题 P，当且仅当：(1) P 为真，(2) S 相信 P，且 (3) S 相信 P 是得到确证的。
Knowledge = Justified True Belief (JTB)
知识 = 确证的真信念 (JTB)
Edmund Gettier challenged this with counterexamples where a belief is true and justified purely by luck, undermining the sufficiency of JTB. This highlights the difficulty of achieving a complete definition of knowledge, often leading to discussions of ‘Gettier cases’.
埃德蒙·盖梯尔用反例挑战了这一定义，其中信念因纯粹运气而为真且得到确证，削弱了 JTB 的充分性。这突显了给出完整知识定义的困难，常引发对“盖梯尔案例”的讨论。
3. The Design Argument for God’s Existence | 上帝存在的设计论证
The design argument, or teleological argument, holds that the order and complexity observed in nature point to an intelligent designer. William Paley’s watchmaker analogy is a classic formulation: if you found a watch upon a heath, you would infer a watchmaker; analogously, the intricate design of organisms and the universe implies a divine designer.
设计论证，亦称目的论论证，主张在自然界观察到的秩序与复杂性指向一位智能设计者。威廉·佩利的手表类比是一个经典表述：若在荒原上发现一只手表，你会推断有一位制表师；类似地，生物体和宇宙的精密设计暗示着一位神圣的设计者。
David Hume criticised the argument by questioning the analogy: the universe is not sufficiently similar to a machine, and even if it were, a flawed design could point to multiple designers or an imperfect god. Moreover, the theory of evolution by natural selection offers a powerful naturalistic explanation for apparent design.
大卫·休谟通过质疑类比来批判这一论证：宇宙与机器并不足够相似，即便相似，有缺陷的设计也可能指向多位设计者或一位不完美的神。此外，自然选择的进化论为表面的设计提供了一个强有力的自然主义解释。
4. The Problem of Evil and Suffering | 恶与苦难的问题
The problem of evil challenges the existence of an omnipotent, omnibenevolent God. If God is all-powerful, He could prevent evil; if all-loving, He would want to. The logical problem of evil argues that the coexistence of God and evil is logically contradictory, whereas the evidential problem cites the sheer amount and distribution of suffering as strong evidence against such a God.
恶的问题对全能、全善的上帝存在构成挑战。如果上帝全能，祂就能阻止恶；如果全善，祂就会想要阻止。恶的逻辑问题认为上帝与恶的并存是逻辑矛盾的，而证据问题则以苦难的巨大数量和分布作为反对这样一位上帝的有力证据。
One key theistic response is the free will defence: a world with free creatures capable of moral good is greater than a world without freedom, but free will necessarily entails the possibility of moral evil. Natural evil is often explained as a consequence of a stable natural order required for free moral choice.
一个有神论的关键回应是自由意志辩护：拥有能够践行道德之善的自由受造物的世界比没有自由的世界更伟大，但自由意志必然带来道德恶的可能性。自然之恶常被解释为自由道德选择所需的稳定自然秩序的后果。
5. Mind and Body: Dualism vs Materialism | 心灵与身体：二元论与唯物主义
The mind-body problem asks how mental states relate to physical states. Substance dualism, famously defended by Rene Descartes, claims that the mind is a non-physical substance distinct from the body. Cartesian interactionism proposes they interact in the pineal gland, but explaining this interaction remains deeply problematic.
心身问题探讨心理状态如何与物理状态相关联。实体二元论由勒内·笛卡尔著名地辩护，主张心灵是独立于身体的非物质实体。笛卡尔交互论提出它们在松果体中交互，但解释这种交互一直是一大难题。
Materialism (or physicalism) denies the existence of a non-physical mind. Reductive physicalism (identity theory) equates mental states directly with brain states, while functionalism defines mental states by their causal roles. Many students examine the ‘hard problem of consciousness’ raised by the subjective, qualitative nature of experience (qualia).
唯物主义（或物理主义）否认非物质心灵的存在。还原物理主义（同一论）直接将心理状态等同于大脑状态，而功能主义则根据因果角色定义心理状态。许多学生会考察由经验的主观质性（感受质）所提出的“意识的难题”。
6. Free Will and Determinism | 自由意志与决定论
Determinism holds that every event, including human choices, is causally necessitated by prior states. This appears to conflict with free will, which requires that we could have done otherwise. Hard determinism accepts the conflict and denies free will; libertarianism rejects determinism and upholds a metaphysically robust free will.
决定论认为每个事件，包括人类选择，都由先前状态因果必然地决定。这似乎与自由意志相冲突，后者要求我们本可以做出不同选择。强硬决定论接受此冲突并否认自由意志；自由意志主义则拒绝决定论并支持一种形而上学扎实的自由意志。
Compatibilism (soft determinism) seeks to reconcile the two: free will is compatible with determinism if we define freedom not as the absence of causation, but as acting according to one’s own desires and intentions without external coercion. This reframes the debate around the conditions of moral responsibility.
相容论（温和决定论）寻求调和二者：如果将自由定义为不受外部强迫地按照自身欲望和意图行事，而非定义为没有原因，则自由意志与决定论相容。这重新框定了关于道德责任条件的辩论。
7. Utilitarianism: Bentham and Mill | 功利主义：边沁与密尔
Utilitarianism is a consequentialist ethical theory stating that the right action is the one that maximises overall happiness or utility. Jeremy Bentham’s act utilitarianism employed the hedonic calculus, weighing intensity, duration, certainty, and extent of pleasure against pain for each individual affected by an action.
功利主义是一种后果论伦理理论，主张正确的行为是能使总体幸福或功用最大化的行为。杰里米·边沁的行动功利主义运用快乐计算法，针对受行为影响的每个个体，权衡快乐相对于痛苦的强度、持续时间、确定性和广度。
John Stuart Mill refined utilitarianism by distinguishing higher intellectual pleasures from lower bodily pleasures, arguing that ‘it is better to be a human being dissatisfied than a pig satisfied.’ He introduced the harm principle, limiting interference with individual liberty to prevent harm to others. Rule utilitarianism later assessed the utility of general rules rather than individual acts.
约翰·斯图亚特·密尔通过区分高级的精神快乐与低级的肉体快乐完善了功利主义，主张“做一个不满的人胜于做一只满足的猪”。他引入了伤害原则，将对个人自由的干涉限制在防止对他人造成伤害的范围内。规则功利主义后来评估的是普遍规则的功用，而非单个行为。
8. Kantian Deontology | 康德义务论
In contrast to utilitarianism, Immanuel Kant’s deontological ethics judges the morality of an action based on duty and the intention behind it, not its consequences. An action has moral worth only if it is performed out of respect for the moral law, not merely in accordance with duty.
与功利主义相对照，伊曼努尔·康德的义务论伦理学根据义务和背后的动机来评判行为的道德性，而非其后果。一个行为只有出于对道德律的敬重而实施时才具有道德价值，而不仅仅是符合义务。
The categorical imperative is the supreme principle of morality. Its first formulation commands: ‘Act only according to that maxim whereby you can at the same time will that it should become a universal law.’ The second formulation insists we treat humanity, whether in ourselves or others, always as an end in itself, never merely as a means.
定言命令是道德的最高原则。其第一形式命令：“只依据你可以同时意欲它成为一条普遍法则的准则去行动。”第二形式强调，我们必须总是将人性，无论是自身还是他人，视为目的本身，而绝不仅仅当作手段。
9. Personal Identity: What Makes You ‘You’? | 人格同一性：什么使你成为“你”？
The problem of personal identity explores what it means for a person at one time to be the same person as at another. The bodily continuity theory claims personal identity is tied to the continuity of the physical organism, particularly the brain. However, thought experiments like brain transplants challenge this.
人格同一性问题探讨一个人在此时与彼时是同一个人意味着什么。身体连续性理论声称人格同一性系于物理有机体的连续性，尤其是大脑。然而，像大脑移植这样的思想实验对此构成挑战。
The psychological continuity theory, associated with John Locke, bases identity on overlapping chains of memory and psychological connections. For Locke, a person is a ‘thinking intelligent being that has reason and reflection and can consider itself as itself.’ Objections include the problem of forgetting and Reid’s brave officer paradox, which shows memory is not perfectly transitive.
与约翰·洛克相关的心理连续性理论将同一性建立在重叠的记忆链和心理联系之上。对洛克而言，人格是“一个能思、有理智、能反省并能在不同的时间和地点将自身视为自身的智能存在”。反对意见包括遗忘问题及里德的勇敢军官悖论，该悖论表明记忆并非完美传递。
10. Applied Ethics: The Sanctity of Life | 应用伦理学：生命的神圣性
Applied ethics applies moral theories to practical dilemmas such as abortion and euthanasia. The sanctity of life principle, rooted in many religious traditions, holds that human life is intrinsically valuable from conception to natural death, and must never be intentionally ended.
应用伦理学将道德理论运用于堕胎和安乐死等实际困境。植根于许多宗教传统的生命神圣性原则主张，人类生命从受孕到自然死亡具有内在价值，决不可被故意终止。
The quality of life approach, often associated with utilitarian reasoning, considers the presence or absence of consciousness, autonomy, and the capacity for pleasure and suffering. A woman’s right to bodily autonomy is central in abortion debates, while in euthanasia debates the principle of compassion and the avoidance of unnecessary suffering are weighed against the wrongness of killing.
生命质量观通常与功利主义推理相关，它考虑意识、自主性以及感受快乐与苦难的能力是否存在。女性身体自主权在堕胎辩论中居于核心，而在安乐死辩论中，同情原则与避免不必要的痛苦需要与杀生的错误性进行权衡。
For both issues, students should be able to apply deontological and consequentialist perspectives, and evaluate arguments concerning personhood, the doctrine of double effect, and the distinction between active and passive cessation of life.
针对这两个议题，学生应能运用义务论和后果论视角，并评估关于人格、双重效应原则以及主动与被动终结生命之间区分的论证。
