1. What is Knowledge? | 什么是知识？
The starting point of epistemology is the attempt to analyse what it means to know something. The traditional, widely accepted analysis is that knowledge is justified true belief (JTB). According to this account, a subject S knows a proposition P if and only if (i) P is true, (ii) S believes that P, and (iii) S is justified in believing that P. Each condition is individually necessary and jointly sufficient for knowledge.
认识论的起点在于试图分析知道某事意味着什么。传统且被广泛接受的分析是，知识即确证的真信念（JTB）。根据这一说明，一个主体 S 知道命题 P，当且仅当 （i）P 为真，（ii）S 相信 P，且（iii）S 有证成地相信 P。这几个条件对知识而言各自必要、合起来又充分。
The justification condition is meant to rule out lucky guesses. Even if a belief turns out true, if the believer had no good reason for holding it, we are reluctant to call it knowledge. Thus, a person who randomly guesses tomorrow’s weather correctly does not know it would rain, even though the belief was true.
证成条件旨在排除幸运的猜测。即使某个信念结果是真的，如果相信者没有充足的理由持有它，我们也不愿称之为知识。因此，一个人随机猜中了明天的天气，即使这个信念是真的，他也并不知道天会下雨。
2. The Gettier Problem | 盖梯尔问题
In 1963, Edmund Gettier published a short paper that shook the foundations of epistemology. He provided counterexamples in which a person has a justified true belief but, intuitively, still lacks knowledge. In a typical Gettier case, the justification is defective because it relies on a false premise, yet the conclusion happens to be true by coincidence.
1963 年，埃德蒙·盖梯尔发表了一篇撼动认识论根基的短文。他给出了一些反例，在这些反例中，一个人持有确证的真信念，但从直觉上看仍缺乏知识。在一个典型的盖梯尔案例中，证成是有缺陷的，因为它依赖于一个错误的前提，而结论却出于巧合碰巧为真。
For example, Smith has strong evidence that Jones owns a Ford (he has seen Jones driving it). Smith then deduces ‘Either Jones owns a Ford or Brown is in Barcelona.’ Unbeknownst to Smith, Jones no longer owns a Ford, but it turns out Brown really is in Barcelona. Smith’s belief is justified and true, but he does not know the disjunction; the truth is accidental.
例如，史密斯有强有力的证据认为琼斯有一辆福特车（他曾看见琼斯开它）。史密斯于是推论’琼斯有一辆福特车或者布朗在巴塞罗那’。史密斯不知道的是，琼斯已经不再拥有福特车了，但结果布朗真的恰好在巴塞罗那。史密斯的信念是有证成的且为真，但他并不知道这个选言命题；这个真是偶然的。
Gettier cases demonstrate that the JTB analysis is insufficient. Philosophers have since tried to strengthen the definition of knowledge, for instance by adding a ‘no false lemmas’ condition or by requiring that the belief is reliably formed. The quest for a complete analysis remains a live project.
盖梯尔案例表明 JTB 分析是不充分的。哲学家们自此尝试加强知识的定义，例如通过添加’无错误引理’条件，或要求信念是可靠形成的。对一种完整分析的追寻依然是一个活跃的课题。
3. Theories of Justification | 证成理论
Once the structure of knowledge is problematised, the nature of justification demands closer attention. Three major theories offer competing accounts of how beliefs can be justified: foundationalism, coherentism, and reliabilism.
一旦知识的结构受到质疑，证成的本质就需要更仔细的审视。三大理论提供了关于信念如何得到证成的竞争性说明：基础主义、融贯论和可靠主义。
Foundationalism holds that all justified beliefs rest upon basic beliefs, which are self-justifying or non-inferentially justified. These foundations might stem from direct sensory experience or self-evident truths. The virtue of foundationalism is that it halts an infinite regress of justification; however, critics question whether any beliefs can truly be ‘basic’ without requiring further support.
基础主义主张所有被证成的信念都倚赖于基础信念，基础信念是自我证成的或非推论性证成的。这些基础可以来自直接的感觉经验或不言自明的真理。基础主义的优点在于它止住了证成的无限回溯；然而批评者质疑是否存在任何无需进一步支撑的真正’基础’信念。
Coherentism rejects foundations altogether. It claims that a belief is justified if it coheres with the rest of the believer’s belief system. Justification is holistic, like finding a web of interlocking support. But coherentism faces the isolation objection: a coherent system of beliefs could be entirely detached from reality, yet still count as justified.
融贯论则全然拒绝了基础。它主张一个信念若能与相信者整个信念系统中的其余信念相融贯，便得到证成。证成是整体性的，仿佛找到一张互相勾连的网。但融贯论面临隔离反驳：一个融贯的信念系统可以完全脱离现实，尽管如此却仍算作得到证成。
Reliabilism shifts the focus from the subject’s internal access to reasons to the external process that produces the belief. A belief is justified if it results from a reliable cognitive process, one that tends to yield true beliefs. Perception and memory are candidate reliable processes. The difficulty lies in specifying exactly what makes a process reliable without circularity.
可靠主义将焦点从主体对理由的内在通达转向产生信念的外部过程。一个信念如果来自一个可靠的认知过程——即倾向于产生真信念的过程——便得到证成。感知和记忆是可靠的候选过程。困难在于，要在不陷入循环的情况下具体说明是什么使得一个过程可靠。
4. Perception: Realism and Idealism | 知觉：实在论与观念论
The philosophy of perception asks how our sensory experiences connect us to the external world. Direct realism is the common-sense view: we directly perceive mind-independent physical objects. When you see a tree, the tree itself is a constituent of your experience. Direct realism is challenged by the argument from illusion, which points out that objects can appear differently to different observers, suggesting we do not perceive them directly.
知觉哲学探讨我们的感官经验如何将我们与外部世界连接起来。直接实在论是常识观点：我们直接感知到独立于心灵的物理对象。当你看见一棵树时，树本身是你经验的一部分。直接实在论受到幻觉论证的挑战，该论证指出，对象对不同观察者会呈现不同样貌，这表明我们并非直接感知它们。
Indirect realism accepts that we only ever perceive sense-data, or mental representations, directly. The external world causes these sense-data, but we never perceive objects themselves. John Locke’s distinction between primary qualities (shape, motion) and secondary qualities (colour, taste) supports this view. The major problem for indirect realism is scepticism: if we only know representations, how can we ever check they match reality?
间接实在论承认我们永远只能直接感知感觉与料或心灵表征。外部世界引起了这些感觉与料，但我们从未感知到对象本身。约翰·洛克对第一性质（形状、运动）和第二性质（颜色、味道）的区分支撑了这一观点。间接实在论的主要问题是怀疑论：如果我们只知道表征，我们又怎能检验它们是否与实在相符？
Idealism, most forcefully defended by George Berkeley, takes a more radical step. It denies that mind-independent matter exists at all. Objects are collections of ideas, and for them to exist is to be perceived (esse est percipi). Berkeley appeals to God as the permanent perceiver to guarantee the continuity of objects. Critics find idealism deeply counterintuitive and worry it collapses into solipsism.
观念论由乔治·贝克莱最有力地捍卫，迈出了更为激进的一步。它否认存在任何独立于心灵的物质。对象无非是观念的集合，存在即被感知（esse est percipi）。贝克莱诉诸上帝作为永恒的感知者来保证对象的连续存在。批评者认为观念论极度反直觉，并担忧它会滑入唯我论。
5. The Problem of Evil | 恶的问题
The problem of evil is perhaps the most powerful objection to the existence of an omnipotent, omnibenevolent, and omniscient God. If God has all three attributes, he would want to eliminate evil, could eliminate it, and would know how to do so. Yet evil exists. This contradiction forms the logical problem of evil, famously articulated by Epicurus and later refined by J.L. Mackie.
恶的问题或许是对全能、全善、全知的上帝存在的最有力反对。如果上帝拥有这三种属性，他就会想要消除恶，能够消除恶，并且知道如何去做。然而恶却存在。这个矛盾构成了恶的逻辑问题，由伊壁鸠鲁著名地提出，后经 J.L. 麦基完善。
Theists offer defences and theodicies in response. A defence aims to show that the existence of God and evil is not logically contradictory, while a theodicy tries to explain why God permits evil. The free will defence holds that God gave humans free will, and the capacity to choose evil is necessary for genuine moral good. Some evil thus stems from human misuse of freedom.
有神论者以抗辩和神义论做出回应。抗辩旨在证明上帝的存在与恶的存在在逻辑上并不矛盾，而神义论则尝试解释上帝为何允许恶。自由意志抗辩主张，上帝赋予了人类自由意志，而选择恶的能力对于真正的道德善是必要的。因此，某些恶源于人类对自由的误用。
The evidential problem pushes further: even if some evil is necessary, the sheer quantity and distribution of suffering seem disproportionate. Why does nature contain so much apparently pointless suffering, like animal pain? The evidential argument claims that the amount of evil makes God’s existence highly improbable, even if not logically impossible.
证据性问题则更进一步：即便某些恶是必要的，苦难的总量和分布也显得极度不成比例。为什么自然中包含如此多明显无意义的苦难，例如动物的痛苦？证据性论证主张，恶的数量使得上帝的存在极不可能，即使它并非逻辑上不可能。
6. The Teleological Argument | 目的论论证
The teleological argument, or argument from design, concludes that the universe’s order and complexity point to an intelligent designer. William Paley’s watchmaker analogy is the classic formulation: if you find a watch on a heath, its intricate arrangement of parts compels you to infer a watchmaker. Similarly, the complexity of the natural world, such as the human eye, compels an inference to a divine designer.
目的论论证，或称设计论证，其结论为宇宙的秩序和复杂性指向一位智慧的设计者。威廉·佩利钟表匠的类比是经典的表述：如果你在荒野上发现一块手表，其零件错综复杂的排列会迫使你推断有一位钟表匠。类似地，自然界的复杂性，比如人的眼睛，也迫使人们推断一位神圣的设计者。
David Hume, writing before Paley, offered devastating criticisms. He argued that the analogy between a watch and the universe is weak; we have experience of watches being designed, but we have no experience of universes being designed. Hume also suggested that even if the argument succeeds, it points to a finite, imperfect designer, or perhaps a committee of designers, not the God of classical theism.
早于佩利的大卫·休谟提出了毁灭性的批评。他主张手表和宇宙之间的类比是薄弱的；我们有手表被设计的经验，却没有宇宙被设计的经验。休谟还指出，即便该论证能够成立，它也指向一位有限的、不完美的设计者，甚或是一群设计者，而非古典有神论的上帝。
In the modern era, the argument has been revitalised by fine-tuning claims. Physicists observe that the fundamental constants of the universe appear exquisitely calibrated to permit life. However, critics counter with the anthropic principle and the possibility of a multiverse, arguing that if countless universes exist, it is not surprising that at least one supports life.
在现代，这一论证因精调的主张而得到复兴。物理学家观察到，宇宙的基本常数似乎被精致地校准以允许生命存在。然而，批评者用人择原理和多重宇宙的可能性加以回应，主张如果存在无数宇宙，那么至少有一个支持生命就不足为奇。
7. The Cosmological Argument | 宇宙论论证
Cosmological arguments attempt to prove God as the ultimate cause of the universe. Thomas Aquinas presented his influential ‘Five Ways,’ the first three of which embody cosmological reasoning: the argument from motion, from efficient causality, and from contingency. All rely on the principle that an infinite regress of causes is impossible; there must be a first unmoved mover or uncaused cause.
宇宙论论证试图证明上帝是宇宙的终极原因。托马斯·阿奎那提出了他影响深远的’五路’，其中前三路体现了宇宙论的推理：从运动出发的论证、从动力因出发的论证以及从偶因性出发的论证。它们都依赖于一条原则：原因的无限回溯是不可能的；必须有一个第一不动的推动者或非原因的原因。
The argument from contingency contrasts necessary and contingent beings. A contingent being depends on something else for its existence; a necessary being exists by its own nature. Aquinas argues that if everything were contingent, nothing would exist now, because contingent beings come into and go out of existence. Therefore, there must be a necessary being upon which all contingent beings depend, and this being is God.
从偶因性出发的论证区分了必然存在和偶然存在。偶然存在依赖于他物而存在；必然存在则凭借自身本性而存在。阿奎那论证说，如果一切都只是偶然存在，那么现在就没有任何东西存在，因为偶然存在物会生灭。因此，必须有一个必然存在，所有偶然存在物都依赖于它，而这就是上帝。
Key objections include David Hume’s challenge to the very idea of a necessary being (we can conceive something not existing) and the possibility that the universe itself is the necessary being. Bertrand Russell famously asserted that the universe is just a brute fact, and it is illegitimate to ask for a total explanation of everything.
关键的反对意见包括大卫·休谟对必然存在这一观念本身的质疑（我们能想象某物不存在），以及宇宙自身就是必然存在的可能性。伯特兰·罗素著名地断定宇宙只是一个赤裸的事实，要求对一切给予总体解释是不正当的。
8. The Ontological Argument | 本体论论证
Unlike a posteriori arguments, the ontological argument is an a priori attempt to deduce God’s existence from the very concept of God. Anselm of Canterbury defined God as ‘that than which nothing greater can be conceived.’ He argued that existence in reality is greater than existence merely in the understanding, so if God existed only in the mind, he would not be the greatest conceivable being. Therefore, God must exist in reality.
与后验的论证不同，本体论论证是一种先验的尝试，试图从上帝的概念本身直接推出上帝的存在。坎特伯雷的安瑟伦将上帝定义为’无法设想比之更伟大的那一位’。他论证说，存在于现实中比仅存在于理解中更伟大，因此如果上帝仅存在于心灵中，他就不是那可设想的最伟大者。因此，上帝必须存在于现实中。
Gaunilo, a contemporary of Anselm, parodied the argument using the example of a perfect lost island: we can conceive of the greatest conceivable island, but that does not mean it actually exists. Anselm replied that the argument works only for the unique concept of a greatest conceivable being, but the parody has continuing bite.
安瑟伦同时代的高尼罗用完美的失落之岛的例子模仿了这一论证：我们可以设想那最伟大的可设想之岛，但这并不意味着它事实上存在。安瑟伦回应说，该论证仅适用于那可设想的最伟大存在这一独特概念，但这一戏仿仍有持续的杀伤力。
Immanuel Kant’s criticism is widely regarded as decisive. Kant argued that ‘existence is not a real predicate.’ Adding ‘exists’ to the concept of a thing does not add to its definition; it merely posits the thing in reality. Thus, we cannot legitimately include existence in the definition of God in order to conclude that God exists without begging the question.
伊曼努尔·康德的批评被广泛认为具有决定性。康德论证说’存在不是真实的谓词’。给一个事物的概念加上’存在’并不会增加其定义内容；它只不过是把该事物设定在现实中。因此，我们不能合理地将存在纳入上帝的定义，然后在此基础上结论上帝存在，却不犯下乞题谬误。
9. Utilitarianism | 功利主义
Utilitarianism is a teleological ethical theory that judges the morality of actions by their consequences. Jeremy Bentham’s act utilitarianism proposes the principle of utility: the right action is the one that produces the greatest happiness for the greatest number. Bentham devised the hedonic calculus to measure pleasure across seven criteria, including intensity, duration, and certainty.
功利主义是一种目的论的伦理理论，它根据行为的后果来判断其道德性。杰里米·边沁的行为功利主义提出了功利原则：正确的行为是为最大多数人带来最大幸福的行为。边沁发明了快乐计算法，通过七个标准来衡量快乐，包括强度、持续时间和确定性。
John Stuart Mill refined utilitarianism, introducing a qualitative dimension. He argued that pleasures of the intellect and moral sentiments are higher than those of mere sensation. Mill’s famous dictum captures this: ‘It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.’ Yet Mill still maintained that the ultimate sanction of morality is happiness.
约翰·斯图尔特·密尔对功利主义加以改良，引入了一个质的维度。他主张理智和道德情操的快乐高于纯粹感官的快乐。密尔那句著名格言抓住了这一点：’宁愿做一个不满足的人，也不做一只满足的猪；宁愿做不满足的苏格拉底，也不做一个满足的傻瓜。’然而，密尔依然坚持道德的终极制裁是幸福。
Common objections include the challenge that utilitarianism can justify blatant injustices if they increase overall happiness, and that it is too demanding, requiring us to constantly calculate the consequences of every action. Rule utilitarianism responds by evaluating rules rather than individual acts, arguing that following rules like ‘do not lie’ generally maximises utility.
常见的反对意见包括：功利主义可以为赤裸裸的不正义辩护，只要它们增加了总体幸福；以及它要求太高，要求我们不断计算每个行为的后果。规则功利主义对此的回应是评估规则而非单个行为，主张遵循诸如’不要撒谎’这类规则通常能最大化功利。
10. Kantian Deontology | 康德义务论
In stark contrast to utilitarianism, Immanuel Kant’s moral philosophy is deontological: the moral worth of an action lies in its intention and conformity to duty, not in its consequences. For Kant, the only intrinsically good thing is a good will. A good will acts out of respect for the moral law, which is discovered through reason alone.
与功利主义形成鲜明对比的是，伊曼努尔·康德的道德哲学是义务论的：一个行为的道德价值在于其动机和对义务的遵守，而不在于其后果。在康德看来，唯一无条件善的东西是善良意志。善良意志出于对道德律的尊重而行动，而道德律是仅通过理性发现的。
The core of Kant’s ethics is the categorical imperative, which commands unconditionally. Its first formulation requires that we ‘act only according to that maxim whereby you can at the same time will that it should become a universal law.’ If a maxim cannot be consistently universalised, the action is morally wrong. Lying fails this test because its universalisation would destroy trust and thus the very practice of promising.
康德伦理学的核心是定言命令，它无条件地发出指令。它的第一公式要求我们’只根据那条你同时能够意愿它成为一条普遍法则的准则而行动’。如果一条准则无法被一贯地普遍化，那么该行为就是道德上错误的。撒谎通不过这个检验，因为它的普遍化会破坏信任，从而摧毁了承诺这种实践本身。
The second formulation demands that we treat humanity, whether in our own person or in the person of another, always as an end and never merely as a means. This principle forbids using people solely for our purposes without respecting their own rational agency. Critics note that Kantian deontology can lead to rigid conclusions, such as forbidding lying even to save an innocent life, and it struggles with genuine moral dilemmas where duties conflict.
第二公式要求我们要永远将人性——无论是自己的人格中还是他人的人格中——总是作为目的，而绝不仅仅作为手段。这一原则禁止我们完全将人仅仅作为达成我们目标的工具，而不尊重他们自己的理性行为能力。批评者指出，康德义务论可能导致僵化的结论，例如甚至禁止为拯救无辜生命而撒谎，并且它在真正的道德两难，即义务之间发生冲突时，显得力不从心。
11. Virtue Ethics | 德性伦理
Virtue ethics shifts the focus from discrete actions and rules to the character of the moral agent. Rooted in Aristotle, it asks not ‘What should I do?’ but ‘What sort of person should I be?’ The ultimate goal of human life is eudaimonia (flourishing), and virtues are the character traits that enable us to achieve it. A virtue is a disposition to act in the right way, lying in a mean between two vices.
德性伦理将焦点从孤立的行为和规则，转向了道德行为者的品格。它植根于亚里士多德，所问的不是’我应当做什么’，而是’我应当成为什么样的人？’人类生活的终极目的是 eudaimonia（繁盛），而德性正是使我们得以达致这一目的品格特征。德性是以正确的方式行动的倾向，它居于两个极端恶习之间的中道。
For example, courage is the mean between cowardice and recklessness; generosity lies between stinginess and wastefulness. Practical wisdom (phronesis) is the intellectual virtue that helps us discern the right mean in each situation. A virtuous person not only acts rightly but does so from a stable disposition and with the appropriate feelings and motives.
例如，勇敢是怯懦与鲁莽之间的中道；慷慨则处于吝啬与挥霍之间。实践智慧（phronesis）是一种理智德性，它帮助我们辨识每一个情境中正确的中道。一个有德性的人不仅行为正确，而且是出于一种稳定的倾向，并伴随着恰当的情感和动机去行动。
Criticisms include the claim that virtue ethics lacks clear action-guidance: faced with a moral dilemma, the instruction ‘act as the virtuous person would’ is vague. Aristotle’s list of virtues may also reflect his cultural context and exclude modern values. Nonetheless, virtue ethics remains attractive for its emphasis on moral education, flourishing, and the richness of moral psychology.
批评意见包括：德性伦理缺乏明确的行动指导——面对道德两难，’如一个有德性之人会做的那样去行动’这样的指示是模糊的。亚里士多德的德性列表也可能反映着他所处的文化语境，而排除了现代价值。尽管如此，德性伦理因其对道德教育、繁盛和丰富的道德心理学的强调，仍然具有吸引力。
