1. What is Philosophy? | 什么是哲学？

Philosophy is the critical examination of fundamental questions about existence, knowledge, values, reason, mind, and language. It does not rely on empirical experiments but on logical analysis, reasoned argument, and conceptual clarity. At A-Level, you will learn to evaluate philosophical theories, identify assumptions, and construct coherent arguments.

哲学是对存在、知识、价值、理性、心灵与语言等根本问题进行批判性审视的学科。它不依赖经验实验，而是借助逻辑分析、理性论证与概念清晰性展开。在 A-Level 阶段，你将学会评析哲学理论、识别前提假设，并构建自洽的论证。

2. Epistemology: The Definition of Knowledge | 认识论：知识的定义

The traditional definition of knowledge is ‘justified true belief’ (JTB). For a person S to know a proposition P, S must believe that P, P must be true, and S must have justification for believing P. This tripartite account was widely accepted until Edmund Gettier’s 1963 paper challenged it with counterexamples where a person has a justified true belief but still seems to lack knowledge.

知识的传统定义是“确证的真信念”（JTB）。一个人 S 要知道命题 P，需要满足：S 相信 P，P 为真，并且 S 对相信 P 有确证。这一三分法被广泛接受，直到埃德蒙·葛梯尔 1963 年的论文通过反例挑战了 JTB：一个人可以拥有确证的真信念，却似乎仍然缺乏知识。

3. Theories of Perception: Direct Realism, Indirect Realism, and Idealism | 知觉理论：直接实在论、间接实在论与观念论

Direct realism claims that we perceive physical objects directly as they are. Indirect realism argues that we perceive physical objects indirectly via sense-data, with John Locke’s primary/secondary quality distinction being central. Idealism, most notably advanced by George Berkeley, holds that the physical world is fundamentally mental, and objects exist only as ideas perceived by minds. Each theory faces challenges, such as the argument from illusion against direct realism, or the problem of scepticism about the external world for indirect realism.

直接实在论声称我们直接感知到物理对象本身。间接实在论则认为我们通过感觉材料间接感知物理对象，洛克的第一性质与第二性质区分是核心。观念论，以乔治·贝克莱最为著名，主张物理世界本质上是心灵的，对象只作为被心灵感知的观念存在。每种理论都面临挑战，比如针对直接实在论的幻觉论证，或者间接实在论面临的外在世界怀疑论难题。

4. Rationalism and Empiricism | 理性主义与经验主义

Rationalism holds that reason is the primary source of knowledge and that we can have innate ideas or a priori knowledge. Descartes, Spinoza, and Leibniz are key figures. Empiricism argues that all knowledge comes from sensory experience; the mind is a tabula rasa at birth. John Locke, George Berkeley, and David Hume are central empiricists. The debate focuses on the origin of concepts and the justification of knowledge, including whether synthetic a priori knowledge is possible.

理性主义认为理性是知识的主要来源，我们可以拥有天赋观念或先天知识。笛卡尔、斯宾诺莎和莱布尼茨是关键人物。经验主义主张所有知识都来自感官经验，心灵在出生时是一块白板。洛克、贝克莱和休谟是核心经验主义者。这一争论聚焦于概念的来源与知识的证成，包括先天综合知识是否可能。

5. Metaphysics: The Mind-Body Problem | 形而上学：身心问题

The mind-body problem concerns the relationship between mental phenomena and physical processes. Substance dualism, defended by Descartes, claims the mind is a non-physical substance distinct from the body. Property dualism holds that mental properties emerge from physical processes but are not reducible to them. Physicalism, or materialism, asserts that the mind is entirely physical, often identified with brain states or functional roles. The hard problem of consciousness, articulated by David Chalmers, questions why physical processes give rise to subjective experience at all.

身心问题关涉心灵现象与物理过程之间的关系。实体二元论，由笛卡尔捍卫，声称心灵是一种非物理的实体，与身体截然不同。属性二元论认为心理属性从物理过程中产生，但不可还原为物理属性。物理主义或唯物主义断言心灵完全是物理的，常被等同于大脑状态或功能角色。大卫·查默斯提出的意识难问题，追问物理过程究竟为何会产生主观体验。

6. Personal Identity | 人格同一性

The problem of personal identity asks what makes a person the same over time. Psychological continuity theories, such as the memory theory associated with John Locke, suggest that overlapping psychological states, especially memory, constitute personal identity. Biological theories emphasize the continuity of the living organism or brain. Derek Parfit’s thought experiments challenge the importance of identity, arguing that what matters for survival is psychological connectedness, not identity per se.

人格同一性问题追问是什么使一个人在不同时间仍是同一个人。心理连续性理论，如与洛克相关的记忆理论，认为重叠的心理状态，特别是记忆，构成了人格同一性。生物理论强调生命有机体或大脑的连续性。德里克·帕菲特的思维实验挑战了同一性的重要性，认为对生存而言重要的是心理联系性，而非同一性本身。

7. Free Will and Determinism | 自由意志与决定论

Determinism holds that every event, including human actions, is necessitated by prior causes and natural laws. If determinism is true, some argue free will is an illusion (hard determinism). Libertarians argue that we have free will that is incompatible with determinism, often invoking agent causation or indeterminacy. Compatibilism, defended by Hume and modern thinkers, claims free will can coexist with determinism if we act according to our desires without coercion. The debate involves moral responsibility, as free will is often seen as a prerequisite for it.

决定论认为每一事件，包括人的行为，都是由先前原因和自然法则必然决定的。如果决定论为真，有人说自由意志只是一种幻觉（强硬决定论）。自由意志论者主张我们拥有与决定论不相容的自由意志，通常诉诸行动者因果性或非决定性。相容论，由休谟和现代思想家辩护，声称只要我们的行为是根据自身欲望且无强制，自由意志就能与决定论共存。这一辩论涉及道德责任，因为自由意志常被视为道德责任的前提。

8. Ethics: Utilitarianism and Kantian Ethics | 伦理学：功利主义与康德伦理学

Utilitarianism is a consequentialist theory: the right action is the one that maximises overall happiness or utility. Jeremy Bentham proposed a quantitative hedonistic calculus, while John Stuart Mill distinguished higher and lower pleasures. Kantian deontology argues that morality is based on duty and reason, not consequences. The categorical imperative requires that we act only according to maxims that we could will to become universal laws, and that we always treat humanity never merely as a means but always as an end in itself. These two theories offer radically different approaches to ethical decision-making.

功利主义是一种后果论理论：正确的行为是能使整体幸福或功利最大化的行为。边沁提出了量化的快乐计算法，而密尔区分了高级快乐与低级快乐。康德义务论主张道德基于义务和理性，而非后果。定言命令要求我们只按照能够同时意愿其成为普遍法则的准则去行动，并且永远把人当作目的本身，而绝不仅仅当作手段。这两种理论为伦理决策提供了截然不同的进路。

9. Philosophy of Religion: Arguments for the Existence of God | 宗教哲学：上帝存在的论证

The design argument (teleological argument) infers from the apparent order and purpose in the world to the existence of an intelligent designer. William Paley’s watchmaker analogy is a classic formulation. The cosmological argument moves from the existence of the universe to a first cause or necessary being; Thomas Aquinas’ Five Ways include versions of this. The ontological argument, proposed by Anselm and developed by Descartes, attempts to deduce God’s existence from the concept of a supremely perfect being. Each argument is subject to significant philosophical criticisms, such as those by Hume, Kant, and contemporary thinkers.

设计论证（目的论论证）从世界呈现的秩序与目的推出一个智慧设计者的存在。威廉·佩利的钟表匠类比是经典表述。宇宙论论证从宇宙的存在推向第一因或必然存在者；托马斯·阿奎那的五路论证包含了不同版本。本体论论证，由安瑟伦提出并经笛卡尔发展，试图从最完善存有的概念中演绎出上帝的存在。每种论证都面临重大哲学批评，如休谟、康德及当代思想家的批判。

10. Religious Language and the Problem of Evil | 宗教语言与恶的问题

Religious language raises issues about how finite human language can describe an infinite God. The via negativa suggests we can only say what God is not. Analogy, as proposed by Aquinas, suggests terms apply to God in a way that is neither univocal nor equivocal. The verification principle of logical positivism held that religious statements are meaningless because they are not verifiable. The logical problem of evil contends that the existence of an all-powerful, all-good God is incompatible with the existence of evil. Theodicies, such as the free will defence, attempt to show this is not a contradiction.

宗教语言提出了有限的人类语言如何描述无限的上帝的问题。否定之道认为我们只能说上帝不是什么。阿奎那提出的类比说认为，词语应用于上帝时既非单义也非歧义。逻辑实证主义的可证实原则曾主张宗教陈述因不可证实而无意义。恶的逻辑问题认为，全能全善的上帝存在与恶的存在不能相容。神正论，如自由意志辩护，试图说明这并不构成矛盾。
