This revision guide identifies the high-frequency topics and recurring mistakes students make in IGCSE WJEC Philosophy. It covers core arguments for God’s existence, the problem of evil, ethical theories, applied ethics, free will and personal identity, with focused advice on how to avoid common errors in evaluation and source-based questions.
本复习指南梳理 IGCSE WJEC 哲学中的高频考点与常见错误。内容涵盖上帝存在的经典论证、恶的问题、伦理理论、应用伦理、自由意志与人格同一性，并针对评价题和资料题中的常见失分点给出具体建议。
1. Exam Structure and Assessment Objectives | 考试结构与评估目标
WJEC IGCSE Philosophy papers usually assess knowledge and understanding (AO1), analysis and evaluation (AO2), and the ability to apply ideas to unfamiliar sources (AO3). A typical question first asks you to explain a concept, then invites you to evaluate a claim such as ‘the design argument proves God’s existence’.
WJEC IGCSE 哲学试卷通常评估知识与理解（AO1）、分析与评价（AO2）以及将观点应用于陌生资料的能力（AO3）。典型题目先要求解释某个概念，再要求评价一个论断，例如“设计论证证明了上帝存在”。
Many students lose marks by writing pure description when the command word is ‘evaluate’. Evaluation requires weighing strengths and weaknesses, not merely listing features.
许多学生因指令词是“评价”时仍写成纯描述而失分。评价需要权衡优点与缺点，而不是仅仅罗列特征。
2. Key Terminology: Validity, Soundness, Necessity | 核心术语：有效性、可靠性、必然性
In philosophical arguments, ‘valid’ means that if the premises are true, the conclusion must follow logically. ‘Sound’ means the argument is valid and all its premises are actually true.
在哲学论证中，“有效”指如果前提为真，结论一定在逻辑上成立。“可靠”指论证有效且所有前提实际上为真。
A frequent mistake is assuming that a valid argument must have a true conclusion. A valid argument can have false premises and therefore a false conclusion, because validity only concerns the logical structure.
常见错误是以为有效论证的结论必为真。有效论证可有假前提，因而结论可能为假，因为有效性只关乎逻辑结构。
Also distinguish ‘necessary’ from ‘contingent’. A necessary proposition must be true in all possible worlds, while a contingent proposition could be true or false depending on circumstances.
还要区分“必然”与“偶然”。必然命题在所有可能世界都为真，而偶然命题视具体情况可真可假。
3. The Design Argument | 设计论证
William Paley’s watch analogy argues that complex order and purpose in the universe imply a designer, just as a watch implies a watchmaker. The argument is inductive and rests on an analogy between natural objects and human artefacts.
威廉·佩利的怀表类比主张，宇宙中的复杂秩序与目的意味着有一位设计者，正如怀表意味着制表匠。该论证是归纳论证，依赖自然物与人造物之间的类比。
Key evaluation points include the strength that apparent design is intuitively compelling, but the weaknesses that evolution by natural selection can explain order without purpose, the analogy may be weak, and even if a designer exists, it does not follow that this is the Christian God; there could be many designers or an imperfect one.
关键评价点包括：显见的设计具有直观说服力，但弱点在于自然选择进化论可在无目的情况下解释秩序，类比可能薄弱，而且即使存在设计者，也不能推出那就是基督教上帝；设计者可能有多位或并不完美。
Common mistake: students often claim the design argument proves the God of classical theism. It only points to some intelligent cause, not necessarily omnipotent, omniscient or morally perfect.
常见错误：学生常声称设计论证证明了古典有神论的上帝。它其实只指向某种理智原因，未必全能、全知或道德完美。
4. The Cosmological Argument | 宇宙论论证
The cosmological argument begins from the existence of the universe or contingent things and argues for a first cause or necessary being. Aquinas’ First Way argues from motion or change to an unmoved mover, often identified with God.
宇宙论论证从宇宙或偶然事物的存在出发，论证第一因或必然存在者。阿奎那的第一路从运动或变化论证一个不动的推动者，通常被等同于上帝。
A common objection is that if everything has a cause, then God must also have a cause. Defenders reply that the argument does not say everything has a cause; it says contingent things need a cause, and God is posited as a necessary being or uncaused cause.
常见反对意见是：如果万物皆有原因，那么上帝也必须有原因。辩护者回应，该论证并非说万物皆有原因，而是说偶然事物需要原因，而上帝被设定为必然存在者或无因之因。
Students often confuse ‘the universe has a cause’ with ‘God is a cause inside the universe’. The cosmological argument places God outside the sequence of causes, as the ground of the whole series.
学生常混淆“宇宙有原因”与“上帝是宇宙内部的一个原因”。宇宙论论证把上帝置于因果序列之外，作为整个序列的根基。
5. Religious Experience and Miracles | 宗教经验与神迹
Religious experiences can be numinous, mystical, corporate or prayer-based. William James argued that such experiences are noetic, transient, passive and ineffable, and that they may provide indirect evidence for the believer, though not proof for the outsider.
宗教经验可分为敬畏型、神秘型、集体型和祈祷型。威廉·詹姆斯认为这些经验具有知识性、短暂性、被动性和不可言说性，它们可为信徒提供间接证据，但对局外人并非证明。
Miracles are usually defined either as violations of natural law, following Hume, or as signs of God’s activity that do not necessarily break natural law, following Holland. Hume also argued that testimony for a miracle can never outweigh the uniform evidence of nature.
神迹通常被定义为对自然律的违反，如休谟所言，或被定义为上帝活动的记号而不必违反自然律，如霍兰德所言。休谟还主张神迹的证词永远无法压倒自然齐一性的证据。
A common mistake is treating religious experience as objective proof. Exam answers should acknowledge that experiences need interpretation and are open to alternative explanations such as psychology or brain states.
常见错误是把宗教经验当作客观证明。考试答案应承认经验需要解释，并可接受心理学或大脑状态等替代解释。
6. The Problem of Evil and Theodicies | 恶的问题与神正论
The logical problem of evil argues that an omnipotent, omnibenevolent God is logically incompatible with any evil. The evidential problem accepts that God and evil are logically compatible but questions whether the amount and distribution of suffering makes God’s existence unlikely.
恶的逻辑问题主张全能、全善的上帝与任何恶在逻辑上不相容。恶的证据问题承认上帝与恶在逻辑上可以相容，但质疑苦难的数量与分布是否使上帝的存在不太可能。
Main theodicies include the free will defence, which says morally significant freedom justifies the possibility of moral evil; soul-making theodicy, which sees suffering as necessary for spiritual growth; and Augustine’s privation theory, which defines evil as a lack of good rather than a positive substance.
主要神正论包括：自由意志辩护，认为具有道德意义的自由使道德恶成为可能；灵魂塑造神正论，认为苦难是灵性成长所必需；奥古斯丁的缺乏说，将恶定义为善的缺乏而非积极实体。
Students often confuse moral evil and natural evil in responses. Moral evil is caused by human choices, while natural evil arises from nature, such as earthquakes; a free will defence addresses moral evil but is weaker against natural evil.
学生作答时常混淆道德恶与自然恶。道德恶由人的选择造成，自然恶则来自自然，如地震；自由意志辩护处理道德恶较强，但面对自然恶则较弱。
7. Ethical Theories: Utilitarianism, Deontology, Virtue Ethics | 伦理理论：功利主义、义务论、美德伦理
Utilitarianism holds that the right action is the one that maximises overall happiness or pleasure. Act utilitarianism judges each action directly by its consequences, while rule utilitarianism follows rules that tend to maximise happiness.
功利主义认为正当行为是能最大化总体幸福或快乐的行为。行为功利主义直接按后果判断每个行为，规则功利主义则遵循通常能最大化幸福的规则。
Kant’s deontology bases morality on duty and the categorical imperative, not consequences. An action is right if it can be universalised and treats persons as ends in themselves, never merely as means.
康德的义务论把道德建立在义务与绝对命令之上，而非后果。一个行为若可普遍化并将人视为目的本身、而不仅仅是手段，就是正当的。
Virtue ethics, from Aristotle, focuses on character and eudaimonia, or flourishing. It asks what kind of person I should become and which virtues, such as courage and honesty, lead to a good life.
美德伦理源自亚里士多德，关注品格与幸福，即人的兴盛。它问的是我应成为什么样的人，以及勇气、诚实等美德如何导向良好人生。
Common mistake in utilitarianism: students calculate the pleasure of the act itself rather than the happiness of everyone affected, or they ignore long-term consequences. In deontology, they confuse acting from duty with acting merely in accordance with duty.
功利主义中的常见错误：学生只计算行为本身的快乐，而非所有受影响者的幸福，或忽视长期后果。在义务论中则混淆“出于义务而行动”与“仅仅符合义务地行动”。
8. Applied Ethics: Abortion and Euthanasia | 应用伦理：堕胎与安乐死
In abortion debates, the sanctity of life view holds that human life is valuable from conception and should not be taken. The quality of life view weighs the woman’s autonomy and the potential child’s wellbeing. Personhood is central: does a foetus have the characteristics of a person, such as consciousness, reason or the capacity to suffer?
在堕胎辩论中，生命神圣观认为人的生命自受孕起就有价值，不应被剥夺。生命质量观则权衡女性的自主权和未来孩子的福祉。人格是核心问题：胎儿是否具有人的特征，如意识、理性或感受痛苦的能力？
For euthanasia, distinguish active euthanasia, where a person is killed, from passive euthanasia, where treatment is withheld or withdrawn. Voluntary euthanasia involves the patient’s request, while non-voluntary occurs when the patient cannot consent. A key argument against legalising voluntary euthanasia is the slippery slope: allowing some cases may lead to abuse.
关于安乐死，要区分主动安乐死，即主动结束患者生命，与被动安乐死，即停止或撤除治疗。自愿安乐死基于患者请求，非自愿安乐死则发生在患者无法同意时。反对自愿安乐死合法化的一个关键论证是滑坡论：允许某些个案可能导致滥用。
Common mistake: treating passive euthanasia as morally equivalent to murder without distinguishing omission from action. Many ethical systems view letting die as different from killing, though this distinction is itself contested.
常见错误：把被动安乐死等同于谋杀，而未区分不作为与行为。许多伦理体系认为任其死亡不同于主动杀害，尽管这一区分本身也受到争议。
9. Free Will and Determinism | 自由意志与决定论
Hard determinism claims that all events, including human actions, are caused by prior conditions, so free will is an illusion. Compatibilism, or soft determinism, holds that free will is compatible with determinism because freedom means acting according to one’s own desires without external coercion.
硬决定论主张所有事件，包括人类行为，都由先前条件决定，因此自由意志是幻觉。相容论，又称温和决定论，认为自由意志与决定论相容，因为自由意味着按自身欲望行动而不受外部强制。
Libertarianism, in the metaphysical sense, argues that humans have genuine free will and that determinism is false. This is often supported by the experience of choice and moral responsibility, but it struggles to explain how uncaused actions can occur.
形而上学的自由意志论主张人拥有真正的自由意志，决定论为假。这通常得到选择经验和道德责任的支持，但很难解释未受原因决定的行为如何发生。
Students frequently confuse determinism with fatalism. Determinism says events are caused by prior states; fatalism says outcomes are fixed regardless of what we do, which removes the relevance of choice and effort.
学生经常混淆决定论与宿命论。决定论说事件由先前状态引起；宿命论说结果无论如何都已注定，从而取消了选择与努力的意义。
10. Personal Identity and the Self | 人格同一性与自我
The soul view claims that personal identity depends on an immaterial soul that persists through change. John Locke’s memory theory grounds identity in psychological continuity: you are the same person as a past self if you remember that self’s experiences.
灵魂观认为人格同一性取决于一个经历变化仍存在的心灵实体。洛克记忆理论把同一性建立在心理连续性上：如果你记得过去自我的经验，你与那个自我就是同一个人。
The body and brain view holds that physical continuity, especially the brain, is necessary for personal identity. Thought experiments such as the Ship of Theseus and teletransportation test whether identity survives gradual replacement or copying.
身体与大脑观认为身体连续性，尤其是大脑，是人格同一性的必要条件。忒修斯之船和远程传送等思想实验检验同一性是否能在逐步替换或复制后存续。
Common mistake: assuming that physical continuity alone is sufficient for personal identity without considering memory loss. Memory theory struggles with cases of forgetting, false memories and split brains, so students should evaluate its limits.
常见错误：认为仅仅身体连续性就足以构成人格同一性，而忽略记忆丧失。记忆理论难以处理遗忘、虚假记忆和裂脑案例，学生应评价其局限。
11. Common Mistakes in Source-Based and Evaluation Questions | 资料题与评价题中的常见错误
In source-based questions, many students fail to quote or paraphrase the source, or they ignore the author’s argument and simply write everything they know about the topic. The source is always a starting point and must be used explicitly.
在资料题中，许多学生不引用或转述资料，或者忽视作者论证而只写自己对该主题的全部了解。资料始终是出发点，必须明确使用。
When asked to evaluate, avoid one-sided answers. Strong responses present at least one argument for and one against, then reach a justified conclusion using criteria such as logical coherence, evidence, simplicity or moral acceptability.
当题目要求评价时，避免单方面答案。优秀答案至少提出一个支持和一个反对的论证，然后依据逻辑一致性、证据、简洁性或道德可接受性等标准得出有根据的结论。
Weak conclusions often say ‘I agree because…’ without criteria. Instead, conclude by saying ‘this argument is stronger/weaker because its premises are more plausible and its objections can be answered’, showing a judgment standard.
薄弱结论常说“我同意是因为……”而没有标准。应改为“该论证更强/更弱，因为其前提更可信且反对意见可被回应”，以显示判断标准。
12. Final Revision Checklist | 最终复习清单
Define all key terms with precise examples: validity, soundness, necessary, contingent, moral evil, natural evil, personhood, active and passive euthanasia, compatibilism and psychological continuity.
用准确例子定义所有核心术语：有效性、可靠性、必然、偶然、道德恶、自然恶、人格、主动与被动安乐死、相容论和心理连续性。
Practise command words such as ‘explain’, ‘compare’ and ‘evaluate’. Use comparison tables to summarise ethical theories and arguments for God’s existence, noting strengths, weaknesses and key scholars.
练习“解释”“比较”“评价”等指令词。使用对比表总结伦理理论和上帝存在论证，标明优点、缺点与关键学者。
In the exam, manage time carefully, write structured paragraphs using PEEL (Point, Evidence, Explanation, Link), and always address the exact question rather than reproducing a prepared essay.
考试中合理分配时间，用 PEEL（观点、证据、解释、联系）结构组织段落，并始终针对具体问题作答，而不是照搬预制文章。
