欢迎来到九年级 SQA 哲学复习指南。本文汇集了你在课程中必须掌握的核心概念、思想家和论证。通过以清晰的英文和中文对照方式分解每个主题，你可以快速掌握内容，为未来的学习打下坚实基础。让我们一起探索哲学提出的宏大问题，学习如何像真正的哲学家一样思考、论证与评价。
1. What is Philosophy? | 什么是哲学？
Philosophy comes from the Greek words ‘philo’ (love) and ‘sophia’ (wisdom). It is the activity of asking fundamental questions about existence, knowledge, values, reason and language. Instead of relying on experiments, philosophers use logical reasoning and critical analysis to explore ideas that cannot be settled by science alone, such as ‘What is a good life?’ or ‘Do we have free will?’
哲学源自希腊词语 ‘philo'(爱)和 ‘sophia'(智慧)。它是对存在、知识、价值、理性和语言等根本问题进行追问的活动。哲学家不依赖实验，而是运用逻辑推理和批判分析来探究科学无法单独回答的问题，例如“什么是美好的生活？”或“我们是否拥有自由意志？”
In SQA Philosophy, you will learn to examine arguments, spot assumptions and develop your own reasoned views. The subject is divided into branches such as epistemology (theory of knowledge), ethics, philosophy of religion and philosophy of mind.
在 SQA 哲学课程中，你将学习审视论证、发现预设并形成自己有理有据的观点。该学科分为若干分支，包括认识论（知识论）、伦理学、宗教哲学和心灵哲学。
2. Logic and Arguments | 逻辑与论证
An argument in philosophy is not a quarrel. It consists of premises (reasons) that are supposed to lead to a conclusion. A good argument is one where the premises support the conclusion in a valid or strong way. We analyse arguments by identifying the premises and checking whether they are true and whether the structure works.
哲学中的论证不是争吵。它由前提（理由）组成，这些前提应当导向某个结论。一个好的论证是前提以有效或强效的方式支持结论。我们通过找出前提、检查它们是否为真以及结构是否合理来分析论证。
For example: ‘All humans are mortal. Socrates is a human. Therefore, Socrates is mortal.’ This is a classic valid argument where the conclusion follows necessarily from the premises. Philosophers regularly ask: ‘Are the premises justified? Is the logic tight?’
例如：“所有人都会死。苏格拉底是人。因此，苏格拉底会死。”这是一个经典的有效论证，结论必然由前提推出。哲学家常常会问：“前提是否合理？逻辑是否严密？”
3. Deductive and Inductive Reasoning | 演绎与归纳推理
Deductive reasoning aims to provide conclusive proof. If the premises are true, the conclusion must be true. Arguments like the Socrates example are deductive. In symbols, a common pattern is:
演绎推理旨在提供结论性证明。如果前提为真，结论必定为真。像苏格拉底那样的例子就是演绎推理。用符号表示，一种常见模式是：
P → Q, P, ∴ Q (Modus Ponens)
Inductive reasoning, on the other hand, offers probable support. It moves from specific observations to general conclusions, such as ‘The sun has always risen; therefore the sun will rise tomorrow.’ Inductive arguments are not guaranteed; they are strong or weak based on the evidence.
另一方面，归纳推理提供可能的支持。它从具体观察走向一般结论，例如“太阳一直以来都升起；因此太阳明天会升起。”归纳论证并非必然，它们基于证据有强弱之分。
You must be able to tell whether an argument is deductive or inductive. In SQA exams, you may be asked to assess the strength of an inductive generalisation or the validity of a deductive form.
你必须能够区分论证是演绎的还是归纳的。在 SQA 考试中，你可能会被要求评价一个归纳概括的强弱，或某个演绎形式的有效性。
4. Fallacies in Reasoning | 推理谬误
A fallacy is a mistake in reasoning that weakens an argument. Common fallacies include ad hominem (attacking the person instead of the argument), straw man (misrepresenting a view to easily refute it) and false dilemma (presenting only two options when more exist).
谬误是推理中的错误，会削弱论证。常见谬误包括人身攻击（攻击人而非论点）、稻草人（歪曲观点以便轻易驳斥）和假两难（仅提供两个选项，而实际存在更多选择）。
Learning to spot fallacies helps you avoid being misled by poor reasoning. Always ask: ‘Is the criticism truly addressing the claim? Are there missing alternatives?’ Recognising fallacies is a core skill in Philosophy.
学会识别谬误有助于你避免被拙劣的推理误导。始终要问：“批评是否真的针对观点本身？是否存在遗漏的其他可能？”识别谬误是哲学的一项核心技能。
5. Epistemology: What is Knowledge? | 认识论：什么是知识？
Epistemology studies what knowledge is and how we acquire it. The traditional definition states that knowledge is ‘justified true belief’ (JTB). For a person to know something, they must believe it, it must be true, and they must have justification (good reasons) for believing it.
认识论研究什么是知识以及我们如何获取知识。传统定义认为知识是“确证的真信念”(JTB)。一个人要知道某事，必须相信它，它必须是真实的，并且他们必须有相信它的理由（确证）。
However, the JTB account was challenged by Edmund Gettier, who produced cases where someone has a justified true belief but still seems not to know. These ‘Gettier cases’ show that knowledge may require something extra, such as a reliable connection to the truth.
然而，JTB 解释遭到埃德蒙·盖梯尔的挑战，他提出了某人拥有确证的真信念却似乎仍不算知道的情形。这些“盖梯尔案例”表明知识可能需要额外的条件，比如与真相的可靠联系。
Philosophers also discuss sources of knowledge: perception, memory, testimony and reasoning. Understanding these foundations prepares you for deeper debates.
哲学家还讨论知识的来源：感知、记忆、证词和推理。理解这些基础为你参与更深入的辩论做好准备。
6. Rationalism vs Empiricism | 理性主义与经验主义
Rationalists argue that reason is the primary source of knowledge. Descartes, a famous rationalist, believed we can gain certain knowledge through innate ideas and logical deduction. His famous saying ‘Cogito, ergo sum’ (I think, therefore I am) was meant to be an indubitable starting point.
理性主义者认为理性是知识的主要来源。著名理性主义者笛卡尔相信，我们可以通过天赋观念和逻辑演绎获得确定的知识。他的名言“我思故我在”意在作为一个无可怀疑的出发点。
Empiricists, such as John Locke and David Hume, hold that all knowledge comes from sensory experience. The mind at birth is a ‘tabula rasa’ (blank slate). We learn by seeing, hearing and touching, not through innate ideas. Hume even argued that causal connections are just habits of thought based on observed regularities.
经验主义者如约翰·洛克和大卫·休谟则认为，所有知识源自感官经验。心灵在出生时是一块“白板”(tabula rasa)。我们通过看、听和触来学习，而非通过天赋观念。休谟甚至主张因果联系只是基于观察规律的思维习惯。
You can compare these two schools using this table:
你可以用下表比较这两大流派：
| Rationalism | Empiricism |
|---|---|
| Knowledge through reason and innate ideas | Knowledge through sense experience |
| Descartes, Spinoza, Leibniz | Locke, Berkeley, Hume |
| A priori knowledge possible (e.g. mathematics) | All knowledge ultimately a posteriori |
7. Ethics: Utilitarianism | 伦理学：功利主义
Utilitarianism is a consequentialist ethical theory, meaning it judges actions by their outcomes. The right action is the one that maximises overall happiness or pleasure and minimises pain. Jeremy Bentham proposed a ‘hedonic calculus’ to measure pleasure by intensity, duration, certainty and extent.
功利主义是一种后果论伦理理论，即根据结果来评判行为。正确的行为是能够最大程度提升总体幸福或快乐、减少痛苦的行为。杰里米·边沁提出了“快乐计算法”，通过强度、持续时间、确定性和范围来衡量快乐。
John Stuart Mill refined the theory by distinguishing higher pleasures (intellectual) from lower pleasures (bodily). He famously said, ‘It is better to be a human being dissatisfied than a pig satisfied.’ Utilitarianism asks you to consider the greatest good for the greatest number.
约翰·斯图亚特·密尔完善了这一理论，区分了高级快乐（智识的）和低级快乐（身体的）。他有句名言：“宁愿做一个不满足的人，也不做一只满足的猪。”功利主义要求你考虑最大多数人的最大利益。
A common criticism is that utilitarianism can justify immoral acts if they produce good consequences, such as punishing an innocent person to please a mob. This shows the importance of also considering justice and rights.
一个常见的批评是，只要能产生好结果，功利主义就可能为不道德的行为辩护，例如为取悦暴民而惩罚无辜者。这表明同时考虑正义与权利的重要性。
8. Ethics: Deontology | 伦理学：道义论
Deontology, associated with Immanuel Kant, argues that actions are right or wrong in themselves, regardless of consequences. Kant proposed the ‘Categorical Imperative’ as a universal moral law: ‘Act only according to that maxim whereby you can at the same time will that it should become a universal law.’
与康德相关的道义论主张，行为本身对错，与后果无关。康德提出了“定言命令”作为普遍的道德法则：“只按照你同时愿意其成为普遍法则的准则去行动。”
Another formulation is to treat humanity always as an end, never merely as a means. This prohibits using people solely for your own benefit. Unlike utilitarianism, deontology respects the inherent dignity of each person and forbids actions like lying or breaking promises even for a good outcome.
另一个表述是：始终把人当作目的，而非仅仅当作手段。这禁止纯粹为自身利益而利用他人。与功利主义不同，道义论尊重每个人的固有尊严，禁止为了好的结果而撒谎或违背承诺等行为。
Kant believed that moral duties are known through reason, not feelings. A good will is the only thing good without qualification. When studying ethics, compare these two theories: one focuses on outcomes, the other on duties.
康德认为道德义务是通过理性而非感觉来认识的。善良意志是唯一无条件的善。学习伦理学时要比较这两种理论：一个关注结果，另一个关注义务。
9. Philosophy of Religion: Design and Cosmological Arguments | 宗教哲学：设计论证与宇宙论论证
The design argument, or teleological argument, claims that the order and complexity of the universe point to an intelligent designer. William Paley used the analogy of a watch: if you find a watch on a heath, you infer a watchmaker due to its intricate parts working together for a purpose. Similarly, the complexity of nature, such as the human eye, suggests a divine designer.
设计论证（目的论论证）认为，宇宙的秩序和复杂性指向一位智慧设计者。威廉·佩利用手表作类比：如果你在荒野中发现一块手表，你会推断有位制表匠，因为其复杂零件为某个目的协同工作。同样，自然界的复杂性，比如人眼，暗示着一位神圣设计者。
David Hume criticised the argument by pointing out that the universe is not exactly like a machine and may have developed through chance or natural processes. The existence of imperfections and suffering also challenges the notion of a perfect designer.
大卫·休谟批评该论证，指出宇宙并不完全像机器，它可能通过偶然或自然过程发展而成。不完美和苦难的存在也挑战着完美设计者的观念。
The cosmological argument seeks a first cause or necessary being to explain why anything exists. Thomas Aquinas argued that everything in motion requires a mover, leading back to an unmoved First Mover (God). Another version states that every contingent being depends on something else, so there must be a necessary being grounding all existence.
宇宙论论证寻求第一因或必然存在来解释为何有物存在。托马斯·阿奎那提出，一切运动的事物都需要推动者，由此追溯到不动的第一推动者（上帝）。另一版本认为，每个偶然存在都依赖他物，因此必有一个必然存在支撑一切存在。
10. Philosophy of Mind: Dualism and Physicalism | 心灵哲学：二元论与物理主义
Dualism is the view that the mind and the body are two distinct substances. Descartes argued that the mind is non‑physical and can exist without the body, while the body is a physical machine. This raises the ‘problem of interaction’: how can a non‑physical mind cause physical actions?
二元论认为心灵和身体是两种不同的实体。笛卡尔主张心灵是非物质的，可以脱离身体存在，而身体是一台物理机器。这引发了“相互作用问题”：非物质的思维如何引起物理行为？
Physicalism, by contrast, claims that everything is physical or supervenes on the physical. Mental states are identical to brain states, or they are functional states that can be realised by physical systems. Gilbert Ryle criticised Cartesian dualism as the ‘ghost in the machine’ error, arguing that the mind is not a separate thing but a set of dispositions and behaviours.
相比之下，物理主义认为一切皆是物理的，或随附于物理事物之上。心理状态等同于大脑状态，或者是可由物理系统实现的功能状态。吉尔伯特·赖尔批评笛卡尔式二元论是“机器中的幽灵”错误，主张心灵并非独立事物，而是一组倾向与行为。
These debates link closely to questions about personal identity and artificial intelligence. In SQA Philosophy, you learn to evaluate the strengths and weaknesses of each position and to apply arguments such as the indivisibility of the mind or the explanatory power of neuroscience.
这些辩论与人格同一性及人工智能问题紧密相连。在 SQA 哲学中，你将学习评价每种立场的优劣，并运用诸如心灵的不可分割性或神经科学的解释力等论证。
