1. The Ontological Argument | 本体论论证
Anselm defines God as ‘that than which nothing greater can be conceived’. If such a being exists only in the mind, we could conceive of a greater being that exists in reality as well; therefore, God must exist in reality.
安瑟伦将上帝定义为“不可设想有比之更伟大者”。若这一存在只存在于心灵中，我们便能设想一个既在心灵中又在现实中存在的更伟大者；因此上帝必然存在于现实中。
Gaunilo parodied the argument by applying it to a perfect island, suggesting one could conclude the island exists just by definition. Anselm replied that the logic applies only to God, as the greatest conceivable necessary being.
高尼罗以“完美的岛屿”戏仿此论证，指出按此逻辑即可推出完美岛屿存在。安瑟伦回应称，该论证仅适用于上帝这一最伟大的必然存在。
Descartes argued that existence is a perfection: God, as a supremely perfect being, must possess the perfection of existence. Kant countered that existence is not a real predicate; it adds nothing to the concept of a thing.
笛卡尔主张“存在是一种完满性”：上帝作为至上完满的存在，必然具备存在这一完满性。康德反驳说，存在并非真正的谓词，它不会给事物的概念增加任何内容。
Modern modal versions, such as Plantinga’s, use possible worlds: if it is possible that a maximally great being exists, then such a being exists in every possible world, hence in the actual world.
现代模态版本（如普兰丁格）借助可能世界加以表述：如果至极伟大者的存在是可能的，那么这一存在便存在于所有可能世界，因而也存在于现实世界。
2. The Cosmological Argument | 宇宙论论证
Aquinas’ Third Way argues from contingency: all things in the world are contingent; if everything were contingent, at some time there would have been nothing; but something exists now, so there must be a necessary being – God.
阿奎那的第三路从偶然性出发论证：世间万物都是偶然的；若一切皆为偶然，则某个时刻必无一物存在；但现在有事物存在，因此必然存在一个必然存在者——上帝。
The Kalam cosmological argument claims that whatever begins to exist has a cause; the universe began to exist; therefore the universe has a cause, identified as God.
卡拉姆宇宙论论证主张，凡开始存在者皆有原因；宇宙开始存在；故宇宙有其原因，这一原因被认定为上帝。
Hume objected that the cosmological argument commits the fallacy of composition (assuming the whole must have a cause because parts do) and that we can imagine nothing existing without contradiction.
休谟的反对意见指出，宇宙论论证犯了合成谬误（因为部分有原因便推论整体有原因），并且设想“本来无一物”并不包含矛盾。
In the famous debate, Bertrand Russell treated the universe as a brute fact requiring no explanation, while Copleston sustained the need for a sufficient reason for existence.
在著名的辩论中，罗素将宇宙视为无需解释的“原初事实”，而科普尔斯顿则坚持必须为存在给出充分的理由。
3. The Teleological Argument | 目的论论证
William Paley’s watchmaker analogy compares the world to a watch: its complexity and purposefulness imply a designer. Likewise, the natural world, with its intricate order, points to a divine designer.
佩利的手表类比将世界比作钟表：其复杂性与目的性暗示着设计者。同样，自然界中精妙的秩序也指向一位神圣的设计者。
Hume, in his Dialogues, anticipated several criticisms: the analogy is weak (the universe is not sufficiently like a machine), even if a designer exists, it may not be the God of classical theism, and the presence of evil suggests an incompetent or malevolent designer.
休谟在《自然宗教对话录》中预先提出了若干批评：类比过弱（宇宙并非十足像机器），即便有设计者，也未必是古典有神论的上帝，而恶的存在则暗示着设计者可能无能或恶意。
Richard Swinburne’s modern version appeals to fine-tuning: the universe’s fundamental constants are so improbably balanced for life that a designer is the most plausible explanation.
理查德·斯温伯恩的现代版本援引“精细调适”说：宇宙的基本常数被调节到极其适合生命出现的程度，因此设计者是最为合理的解释。
Darwin’s theory of evolution by natural selection offers a naturalistic alternative: apparent design arises from random variation and the survival of the fittest, without the need for a designer.
达尔文的自然选择演化论提供了一种自然主义解释：表面上的设计源于随机变异和适者生存，无需设计者。
4. Religious Experience | 宗教体验
William James identified four characteristics of mystical experience: ineffability, noetic quality (insight), transiency, and passivity. He argued that such experiences carry authority for the person who has them.
威廉·詹姆斯归纳了神秘体验的四个特征：不可言说性、知悟性（即洞见）、暂时性与被动性。他主张此类体验对亲历者具有权威。
Swinburne’s principle of credulity states that we should believe things are as they appear to be unless we have defeating evidence. Applied to religious experiences, they should be taken as veridical unless there are strong reasons against them.
斯温伯恩的“轻信原则”指出，除非有击败性证据，否则我们应相信事物如其所呈现的那样。将此原则用于宗教体验，则应将其视为真实，除非有强有力的反驳理由。
Critics point to psychological and neurological accounts: Freud saw religious experience as wish-fulfilment, while neuroscientists link it to temporal lobe activity. The diversity of conflicting religious experiences also undermines their evidential force.
批评者指出了心理学和神经学的解释：弗洛伊德将宗教体验视为愿望的实现，神经科学家则将之与颞叶活动联系起来。相互冲突的宗教体验的多样性也削弱了其作为证据的力量。
5. The Problem of Evil | 恶的问题
J.L. Mackie formulated the logical problem of evil as an inconsistent triad: God is omnipotent, God is wholly good, yet evil exists. If God is omnipotent and benevolent, evil should not exist.
麦基将恶的逻辑问题表述为不相容的三难困境：上帝是全能的，上帝是全善的，然而恶却存在。如果上帝全能全善，恶就不应该存在。
The Augustinian theodicy holds that evil is a privation of good, resulting from the misuse of free will by angels and humans. God allows evil to preserve free will and will ultimately restore harmony.
奥古斯丁神义论主张，恶是善的缺失，源于天使和人类对自由意志的误用。上帝允许恶存在是为了保全自由意志，并终将恢复和谐。
The soul-making theodicy, developed by Irenaeus and John Hick, contends that evil and suffering are necessary for moral and spiritual growth; the world is a vale of soul-making.
爱任纽与希克发展的灵魂塑造神义论认为，恶与苦难是道德和灵性成长所必需的；世界是一个“塑造灵魂的幽谷”。
Challenges include the sheer quantity of gratuitous evil (Rowe), the problem of animal suffering that serves no apparent purpose, and the apparent injustice of hell if salvation depends on circumstances.
面临的挑战包括大量无谓的恶（罗伊）、无明显目的的动物之苦难，以及如果救赎取决于境遇，地狱之存在显得不公的问题。
6. Religious Language | 宗教语言
The logical positivists’ verification principle held that a statement is meaningful only if it is empirically verifiable. Since claims about God cannot be verified by sense experience, they were deemed meaningless.
逻辑实证主义者的可证实原则认为，一个陈述只有当它可被经验证实时才有意义。既然关于上帝的断言无法通过感官经验证实，它们便被视作无意义。
Antony Flew’s falsification challenge demanded that believers specify what could count against their claims. If nothing is allowed to falsify a religious claim, it dies the “death of a thousand qualifications”.
安东尼·弗卢的证伪挑战要求信徒们指明何种情况能驳倒其主张。如果宗教断言不容任何证伪，它将因“千重限定而死亡”。
Wittgenstein’s later philosophy suggests religious language operates as a ‘language game’ within a form of life; meaning is given by use, not by reference to empirical facts.
维特根斯坦后期哲学指出，宗教语言在某种生活形式的“语言游戏”中运作；意义由用法赋予，而非参照经验事实。
Other approaches include Aquinas’ analogical predication (using proportion and attribution), Paul Tillich’s symbolic language, and Bultmann’s programme of demythologisation.
其他进路包括阿奎那的类比谓述（比例类比与归因类比）、保罗·蒂利希的象征语言以及布尔特曼的“去除神话化”纲领。
7. Ethical Theories: Utilitarianism | 伦理学理论：功利主义
Bentham’s act utilitarianism uses the hedonic calculus to maximise pleasure over pain. It measures factors such as intensity, duration, certainty, and extent for every individual affected.
边沁的行为功利主义运用快乐计算法来追求最大化的快乐与最小化的痛苦，对每个受影响的个体衡量强度、持久度、确定性和范围等因素。
Mill refined utilitarianism by distinguishing higher (intellectual) pleasures from lower (bodily) pleasures and argued for rule utilitarianism: following general rules that tend to promote the greatest happiness.
密尔将功利主义加以精致化，区分高级（智识的）快乐与低级（身体的）快乐，并倡导规则功利主义：遵循那些往往能促进最大幸福的一般规则。
Strengths include its intuitive appeal, impartiality, and its capacity to resolve moral dilemmas by calculating consequences. Critics argue that it can sanction injustice if the majority benefits, ignores the separateness of persons, and is overly demanding.
优点在于其直觉吸引力、不偏不倚以及通过计算后果来解决道德困境的能力。批评者认为，若为了多数人利益，它可能认可不正义，忽略了人的分立性，且要求过高。
8. Ethical Theories: Kantian Deontology | 伦理学理论：康德义务论
Kant’s ethics centres on the good will, which acts out of duty, not inclination. An action has moral worth only if it is done from duty and in accordance with the categorical imperative.
康德的伦理学以善良意志为核心，善良意志因义务而非偏好而行动。一个行为只有因义务而为且合乎定言令式时，才具有道德价值。
The first formulation of the categorical imperative is universalizability: ‘Act only according to that maxim whereby you can at the same time will that it should become a universal law.’
定言令式的第一表述为普遍化：“只按你同时也能意愿其成为一项普遍法则的准则去行动。”
The second formulation insists on treating humanity always as an end in itself, never merely as a means. It grounds human dignity and forbids exploitation.
第二表述要求总是把人当作目的本身，绝不仅仅当作手段。这奠定了人的尊严，并禁止剥削。
Strengths include its strong protection of individual rights and justice. Weaknesses include the problem of conflicting duties, the rigidity of rules, and the disregard for consequences in certain tragic scenarios.
优点在于对个人权利和正义的有力保护。缺点包括义务冲突的问题、规则的刻板性，以及在特定悲剧情境下对后果的忽视。
9. Ethical Theories: Virtue Ethics | 伦理学理论：美德伦理学
Aristotle’s virtue ethics focuses on the agent rather than actions. The goal is eudaimonia (human flourishing), achieved by cultivating virtues, which are stable character dispositions lying in a mean between two vices.
亚里士多德的美德伦理学聚焦于行动者而非行为本身。其目标是 eudaimonia（人的繁荣），通过培养各种美德来实现；美德是处两个极端之间的中道状态，是稳定的品格倾向。
Virtues such as courage, temperance, and justice are developed through habituation and phronesis (practical wisdom). Modern virtue ethicists like Anscombe and MacIntyre revived this tradition.
诸如勇敢、节制与正义等美德通过习惯化与实践智慧（phronesis）培养而成。安斯康姆与麦金太尔等现代美德伦理学家复兴了这一传统。
Strengths include its attention to moral motivation, character development, and the whole of a human life. It offers a more flexible approach than rigid rule-based systems.
其优点包括关注道德动机、品格养成以及整个人生，提供了比僵化的规则体系更为灵活的思路。
Criticisms claim it provides no clear action guidance in specific dilemmatic situations and can slide into relativism, as different societies nurture different virtues.
批评者指出，它在具体两难情境中无法提供明确的行为指导，而且由于不同社会培育不同的美德，可能滑向相对主义。
10. Meta-ethics | 元伦理学
Moral realism holds that moral properties exist objectively. Ethical naturalism (e.g., utilitarianism) reduces moral properties to natural facts, while intuitionism (G.E. Moore) claims goodness is a simple, non-natural property known by intuition.
道德实在论主张道德属性客观存在。伦理自然主义（如功利主义）将道德属性还原为自然事实，而直觉主义（摩尔）则认为善是一种单一、非自然的属性，通过直觉获知。
Moral anti-realism denies objective moral facts. Emotivism (Ayer, Stevenson) holds that moral statements express emotions or commands; prescriptivism (Hare) sees them as universal prescriptions; error theory (Mackie) asserts that all moral claims are false because there are no objective values.
道德反实在论否认客观道德事实。情感主义（艾耶尔、史蒂文森）认为道德陈述表达情感或命令；规约主义（黑尔）视之为普遍的劝令；错误理论（麦基）则断言所有道德主张皆为假，因为不存在客观价值。
The queerness argument (Mackie) contends that objective values would be metaphysically and epistemologically queer entities, unlike anything else in the world. The Frege-Geach problem presents a challenge for emotivism: how can moral terms function logically when embedded in unasserted contexts?
怪异论证（麦基）主张，客观价值将是形而上学上和认识论上怪异的实体，与世界中的任何事物都不相似。弗雷格-吉奇问题对情感主义构成挑战：当道德术语被嵌入非断言语境时，它们如何发挥逻辑功能？
11. Free Will and Determinism | 自由意志与决定论
Hard determinism holds that all events, including human actions, are causally determined by prior states. Since free will requires the ability to do otherwise, it is an illusion, and moral responsibility is undermined.
严格决定论主张一切事件（包括人的行为）都由先前状态因果地决定。既然自由意志要求有做其他选择的能力，自由意志便是一个幻觉，道德责任也因此受到削弱。
Libertarianism argues that determinism is false, and humans possess a special form of agent causation that enables genuine free choice, making moral responsibility possible.
自由意志论则主张决定论是错误的，人拥有一种特殊的“行动者因果作用”，使真正自由的选择成为可能，从而道德责任得以成立。
Compatibilism (soft determinism) maintains that free will is compatible with determinism. For Hume and modern compatibilists, freedom means being able to act according to one’s desires and without external constraint, even if those desires are determined.
相容论（温和决定论）坚持自由意志与决定论相容。对休谟和现代相容论者而言，自由意味着能按自己的欲望行动且不受外部强制，即便那些欲望本身是被决定的。
Implications for ethics: if hard determinism is true, retributive punishment becomes unjustified, and moral praise and blame lose their rational basis. Compatibilism attempts to preserve ordinary moral practices.
对伦理学的影响：如果严格决定论为真，报复性惩罚便失去了正当性，道德赞扬与谴责也失去了理性根基。相容论则试图保全日常的道德实践。
12. Mind-Body Dualism vs Materialism | 心身二元论与唯物主义
Substance dualism, most famously defended by Descartes, claims the mind is a distinct non-physical substance. Descartes’ arguments include the argument from doubt (I can doubt my body exists but not my mind) and the conceivability argument (I can conceive of the mind existing without the body).
实体二元论由笛卡尔著名地辩护，认为心灵是非物理的实体。笛卡尔的论证包括“怀疑论证”（我可以怀疑身体存在，但不能怀疑心灵存在）以及“可设想性论证”（我能设想心灵没有身体而存在）。
Materialism asserts that mental states are ultimately physical. Identity theory holds that mind states are identical to brain states. Eliminative materialism goes further, claiming that folk psychological concepts like belief and desire will be eliminated by neuroscience.
唯物主义主张心理状态终究是物理的。同一论认为心灵状态与大脑状态是同一的。取消式唯物主义更进一步，主张诸如信念、欲望等民间心理学概念将被神经科学取消。
Functionalism treats mental states in terms of their causal roles: a pain is whatever state is caused by tissue damage and causes withdrawal and distress. This allows mental states to be realised by different physical substrates (multiple realisability).
功能主义以因果角色来界定心理状态：疼痛便是由组织损伤引起并导致退缩与痛苦的那个状态。这使得心理状态可以基于不同物理基质来实现（多重可实现性）。
The problem of interaction questions how a non-physical mind can interact with a physical body. For dualism, this remains a major difficulty. For materialism, the challenge is to account for subjective qualitative experience (qualia), famously highlighted by the knowledge argument and the philosophical zombie thought experiment.
相互作用难题质疑非物理的心灵如何与物理的身体相互作用。对二元论而言这是一大困难。对唯物主义来说，挑战则在于如何解释主观的感受质（qualia），“知识论证”和“哲学僵尸”思想实验鲜明地突出了这一点。
