1. The Divine Attributes | 上帝的神圣属性
In classical theism, God is typically defined as a being that possesses the attributes of omnipotence, omniscience, and supreme goodness. Omnipotence is often understood as the ability to do anything that is logically possible; absolute omnipotence would include the capacity to bring about logically impossible states of affairs, but most philosophers restrict the attribute to what is coherent. The well-known paradox of the stone asks: can God create a stone so heavy that He cannot lift it? If He cannot create such a stone, there is something He cannot do; if He can, then there is a stone He cannot lift, again implying a limitation. Many theists respond by refining omnipotence to mean the power to do all logically possible acts, resolving the paradox.
在古典有神论中，上帝通常被定义为具有全能、全知和至善属性的存在。全能通常被理解为能做到一切逻辑上可能之事的属性；绝对的全能会包含实现逻辑上不可能事态的能力，但多数哲学家将其限定在融贯的范围内。著名的“石头悖论”问道：上帝能否创造一块自己搬不动的石头？若他不能创造，便有一事他做不了；若他能创造，则有一块他搬不动的石头，同样隐含限制。许多有神论者通过将全能精炼为能做一切逻辑上可能的行为的能力，从而消解这一悖论。
Omniscience is the property of knowing all true propositions. This raises the question of whether divine foreknowledge is compatible with human free will. If God infallibly knows that I will perform action X tomorrow, then it is necessarily true that I will do X, seeming to eliminate my freedom to do otherwise. Some replies appeal to a timeless eternity: God sees all moments in a single eternal present, so His knowledge does not causally determine the future. The attribute of supreme goodness generates the Euthyphro dilemma: is an action right because God commands it, or does God command it because it is right? The first horn makes morality arbitrary; the second suggests morality exists independently of God.
全知是知道一切真命题的属性。这引出了问题：上帝的预知是否与人的自由意志相容。若上帝无误地知道明天我将做行动 X，则“我将做 X”必然为真，这似乎剥夺了我另行选择的自由。一些回应诉诸无时间的永恒：上帝在一个永恒的“当下”中注视所有时刻，因此他的知识并未因果地决定未来。至善的属性产生了“游叙弗伦两难”：一个行动是善的是因为上帝命令它，还是上帝因它本身是善的才命令它？第一个分歧让道德变得任意；第二个则暗示道德独立于上帝而存在。
2. The Ontological Argument | 本体论论证
Anselm’s ontological argument defines God as ‘that than which nothing greater can be conceived’. He argues that such a being must exist in reality, because a being that exists both in the mind and in reality is greater than one that exists only in the mind. If God existed only in the mind, we could conceive of a greater being – one that also exists in reality – which would be a contradiction. Hence God exists. Gaunilo replied using the analogy of a perfect island: we can conceive of the greatest conceivable island, but that does not bring it into existence. Anselm’s response is that the argument applies only to a necessary being, not to contingent objects like islands.
安瑟伦的本体论论证将上帝定义为“无法设想有比之更伟大者”。他论证说，这样一个存在必然存在于现实中，因为同时存在于心中与现实中的存在，比仅存在于心中的存在更伟大。若上帝仅存在于心中，我们便能设想一个更伟大的存在者——即兼具现实存在者——这便产生了矛盾。因此上帝存在。高尼罗用“完美岛屿”的类比回应：我们可以设想最伟大的岛屿，但这并不会让它存在。安瑟伦的回应是，该论证只适用于必然存在者，而不适用于岛屿之类的偶然对象。
Descartes offered a different version: existence is a perfection, and God, as the supremely perfect being, must possess all perfections; therefore God exists. Kant famously objected that existence is not a real predicate or perfection – it does not add to the concept of a thing. When we say that a thing exists, we are not attributing a property to it, but rather positing that the concept is instantiated. Thus the ontological argument fails because it treats existence as if it were a characteristic that a being could lack.
笛卡尔提供了另一个版本：存在是一种完善性，上帝作为至上完善的存在者，必然具备一切完善性；因此上帝存在。康德的著名反驳指出，存在不是真实的谓词或完善性——它并不增加事物的概念。当我们说某物存在时，我们并非为其赋予一种属性，而是断定该概念有实例对应。因此，本体论论证因将存在当作一个存在者可以缺乏的特征而失败。
3. The Design Argument | 设计论证
William Paley’s watchmaker analogy argues that just as the complexity and purposeful arrangement of a watch implies an intelligent designer, the far greater complexity of the natural world implies a divine designer. The argument is a posteriori and inductive: from the observation of order and apparent purpose, we infer a designer. Hume, through the character Philo, offered multiple criticisms before Paley’s work. He argued that the universe is not sufficiently similar to a machine to warrant the analogy; the presence of evil and imperfection suggests a flawed or limited designer; and even if a designer were needed, the argument does not establish the God of classical theism – it could be an inferior deity, a plurality of gods, or an apprentice god.
威廉·佩利的“钟表匠类比”论证：如同钟表的复杂与目的性安排暗示一位理性的设计者，自然世界远更巨大的复杂性则暗示一位神圣设计者。该论证是后天归纳的：从观察到的秩序与显明的目的出发，我们推出一位设计者。休谟通过菲罗之口，在佩利之前就提出了多重批评。他认为宇宙与机器不够相似，不足以支撑类比；恶与不完美的存在暗示设计者有缺陷或能力有限；并且即使需要设计者，该论证也无法确立古典有神论的上帝——它可能是一位次级神祇、多神或学徒神。
Contemporary versions focus on the fine-tuning of the universe. The fundamental physical constants and initial conditions appear to be incredibly finely tuned to permit life; even a minuscule variation would make life impossible. The inference to design is challenged by the multiverse hypothesis: if there are infinitely many universes with varying constants, it is unsurprising that at least one, our own, supports life. Critics also point out that the argument from fine-tuning assumes that life is an intended goal, which may rest on an anthropocentric bias.
当代版本聚焦于宇宙的微调。基本物理常数与初始条件似乎被极度精准地调整，以允许生命存在；哪怕极微小的改变也会使生命不可能。推出设计者面临着多重宇宙假说的挑战：若存在无限多个具有不同常数的宇宙，那么至少有一个（我们的宇宙）支持生命便不足为奇。批评者还指出，微调论证预设了生命是一个被意图达成的目的，这或许基于人类中心偏见。
4. The Cosmological Argument | 宇宙论论证
Aquinas’ first three ways are classic cosmological arguments. The First Way argues from motion (change): things are in a state of change, and whatever is moved must be moved by another; this chain cannot regress infinitely, so there must be a first unmoved mover, which is God. The Second Way argues from efficient causation: every event has a cause, and an infinite regress of causes is impossible, therefore a first uncaused cause exists. The Third Way argues from contingency: contingent beings depend on something else for their existence; if everything were contingent, there could have been a time when nothing existed, and then nothing would exist now, which is absurd. Hence a necessary being, God, must exist to sustain all contingent beings.
阿奎那的前三路是经典的宇宙论论证。第一路从运动（变化）出发：事物处于变化中，凡被推动者必被他者所推动；此链条不能无穷回溯，故必需有一不被推动的第一推动者，即上帝。第二路从动力因出发：每个事件都有原因，原因的无穷回溯不可能，因此存在一个第一无因之因。第三路从偶然性出发：偶然存在者依赖他物而存在；若一切皆偶然，可能曾有一刻无物存在，那么现在也应无物存在，这是荒谬的。因此，必须有一必然存在者（上帝）维系一切偶然存在者。
The Kalam cosmological argument, defended by William Lane Craig, adds an emphasis on temporal finitude: everything that begins to exist has a cause; the universe began to exist; therefore the universe has a cause, which is identified as God. Hume and Russell challenged the very principle of sufficient reason and causal necessity. Hume argued we never experience the necessity of a cause; we only observe constant conjunction. Russell claimed the universe just is, and asking for a cause of the whole is a category mistake. The argument also faces the question of why the first cause must have the attributes of God.
威廉·莱恩·克雷格辩护的卡拉姆宇宙论论证强调时间上的有限性：一切开始存在者皆有原因；宇宙开始存在；故宇宙有一原因，被认定为上帝。休谟和罗素挑战了充足理由原则和因果必然性。休谟认为我们从未经验到原因背后的必然性，只观察到恒常连结。罗素则声言宇宙就是如此，追问整体之因乃范畴谬误。该论证还面临问题：为何第一原因必须具备上帝的属性。
5. The Problem of Evil | 恶的问题
The logical problem of evil presents an inconsistent triad: God is omnipotent, omnibenevolent, and evil exists. If God is all-powerful, He can prevent evil; if He is all-loving, He would want to. Since evil exists, an omnipotent and omnibenevolent God cannot exist. J.L. Mackie argued that no theodicy can successfully reconcile these three propositions unless at least one is qualified. The free will defence, developed by Alvin Plantinga, asserts that it is logically possible that God could not create a world with both free moral agents and no moral evil, because genuine freedom requires the possibility of choosing wrongly. A world with free creatures who sometimes do evil is a greater good than a world of automata.
恶的逻辑问题呈现了一个不相容的三元组：上帝全能、全善，而恶存在。若上帝全能，他能阻止恶；若他全善，他会想要阻止。既然恶存在，全能全善的上帝便不能存在。J.L.麦基论证说，任何一种神正论都无法成功调和这三个命题，除非至少限定其中一个。阿尔文·普兰丁格发展的自由意志辩护主张，在逻辑上“上帝不能创造既有自由道德主体又无道德恶的世界”是可能的，因为真正的自由要求犯错的可能性。拥有有时行恶的自由受造物的世界，比充满自动机的世界更具更高的善。
The evidential problem, formulated by William Rowe, focuses on the sheer quantity and distribution of seemingly pointless suffering. It argues that there exist instances of intense suffering that a loving God could have prevented without forfeiting any greater good; therefore, God probably does not exist. John Hick’s soul-making theodicy responds by interpreting suffering as necessary for moral and spiritual development. Evil provides the obstacles through which virtues such as courage and compassion are formed. Critics question whether the amount of suffering is truly proportionate to soul-making, and why an omnipotent God could not create beings already perfected in virtue without suffering.
威廉·罗阐发的证据问题聚焦于大量看似毫无意义的苦难。其论证指出，存在着某些极其剧烈的苦难，一位慈爱的上帝本可以阻止它们而不牺牲任何更大的善；因此上帝很可能不存在。约翰·希克的灵魂塑造神正论回应说，苦难对于道德与灵性成长是必要的。恶所提供的障碍，正是铸就勇气、同情等德性的途径。批评者质疑苦难的数量是否真的与灵魂塑造成比例，以及为何全能的上帝不能创造无须经历苦难便已美德完备的存在者。
6. Religious Language | 宗教语言
The verification principle, proposed by the logical positivists, holds that a statement is only meaningful if it is either analytically true or empirically verifiable. Ayer argued that religious claims such as ‘God exists’ are neither true by definition nor verifiable by sense experience, and are therefore cognitively meaningless. Flew applied the falsification principle to religious language, using the parable of the gardener. He contended that religious believers allow nothing to count against their assertions, so their claims ‘die the death by a thousand qualifications’ and lack factual significance. Hare responded with the notion of ‘blik’ – a fundamental, non-falsifiable framework through which one interprets experience – arguing that religious bliks still shape life in meaningful ways.
由逻辑实证主义者提出的可证实原则认为，一个陈述仅当其为分析为真或可被经验证实时才有意义。艾耶尔主张，像“上帝存在”这样的宗教论断既非定义真，亦不能由感官经验证实，因此在认知上无意义。弗卢将可证伪性原则应用于宗教语言，使用了无形园丁的寓言。他主张，宗教信徒不允许任何事实被视为否定自己断言的反证，因此其宣称在“千般限定中死去”，缺乏事实意义。黑尔以“布利克”（不可证伪的根本诠释框架）概念回应，认为宗教布利克仍然以有意义的方式塑造着生命。
Alternative accounts suggest religious language is meaningful through analogy, symbol, or non-cognitive expression. Aquinas argued that we speak of God analogically: terms like ‘good’ apply to God not univocally (exactly the same sense as with creatures) or equivocally (totally different), but analogously, based on a proportion between Creator and creation. Wittgenstein’s later work inspired the view that language has meaning only within its specific ‘language game’ and form of life. On this view, religious language is meaningful within the religious way of life, and it is a mistake to demand that it conform to scientific standards of verification.
另类理论认为，宗教语言可以通过类比、象征或非认知表达而具有意义。阿奎那主张我们以类比方式谈论上帝：“善”等词语用于上帝时并非单义地（与受造物意义完全相同）或歧义地（完全不同），而是基于创造者与被造物之间的比例进行类比。维特根斯坦后期思想启发了一种观点：语言只在特定的“语言游戏”和生活形式中具有意义。依此观点，宗教语言在宗教生活方式内具有意义，强求其符合科学的证实标准乃是错置。
7. Substance Dualism | 实体二元论
Substance dualism is the view that mind and body are two fundamentally distinct substances. Descartes’ conceivability argument states: I can clearly and distinctly conceive of myself as a thinking thing without a body, and of my body as an extended thing without thought. Since I can conceive of their separation, it is metaphysically possible, and thus mind and body are distinct. The divisibility argument adds that the body is divisible into spatial parts, while the mind is utterly indivisible; therefore, they cannot be the same substance. The interaction problem, pressed by Princess Elisabeth of Bohemia, asks how an immaterial mind can cause changes in a material body (and vice versa) if they share no common properties.
实体二元论主张心灵与身体是两种根本不同的实体。笛卡尔的可设想性论证：我能清楚分明地将自己设想为一个无身体的思维之物，也能将身体设想为一个无思维的有广延之物。既然我能设想它们的分离，这便在形而上学上可能，故心灵与身体乃是不同实体。可分性论证补充说，身体可以分割为空间部分，而心灵则全然不可分割；因此它们不可能是同一实体。波希米亚伊丽莎白公主提出的互动难题追问：非物质的心灵如何能在与物质身体毫无共性的情况下引致其变化（反之亦然）？
The problem of other minds challenges dualism: if we can only directly access our own mental states, what justifies our belief that other bodies have minds? The argument from analogy suggests that we observe similar behaviour in others and infer their mental life from our own case. However, this is a weak inference from a single instance. The argument from best explanation holds that postulating other minds best explains the complex behaviour of others. Yet dualism’s commitment to private, non-physical souls makes the evidence of behaviour always indirect, leaving scepticism live.
他人之心问题向二元论提出了挑战：若我们只能直接通达自身的心理状态，凭什么相信他者的身体拥有心灵？类比论证指出，我们观察到他者与自己相似的行为，并从自己的事例推断出他者的内心生活。然而，这是基于单一事例的脆弱推论。最佳解释论证则认为，假定他心存在能最好地解释他者复杂的行为。但二元论对私密、非物理灵魂的承诺，令行为证据始终只是间接的，从而让怀疑论难以消除。
8. Property Dualism and the Knowledge Argument | 属性二元论与知识论证
Property dualism holds that, while there may be only one kind of substance (physical), mental properties are non-physical and irreducible. Frank Jackson’s knowledge argument features Mary, a brilliant scientist who has lived her entire life in a black-and-white room and knows all the physical facts about colour vision. Upon leaving the room and seeing red for the first time, Mary learns what it is like to see red. Since she knew all the physical facts beforehand but still learned something new, physical facts do not exhaust all facts; thus, phenomenal qualia are non-physical properties.
属性二元论主张，虽然可能只有一种实体（物理实体），但心理属性是非物理的、不可还原的。弗兰克·杰克逊的知识论证以科学家玛丽为思想实验：玛丽一生住在黑白房间里，知道关于色觉的一切物理事实。当她走出房间第一次看见红色时，她学到了看红色的“感受如何”。由于她此前已知一切物理事实却仍学到了新东西，故物理事实并未穷尽一切事实；因此，现象性的感受质是非物理属性。
Nagel’s ‘what it is like’ argument insists that no amount of objective, physical description can capture the subjective character of experience. To know what it is like to be a bat, one must have a bat’s point of view. Similarly, the zombie argument by Chalmers asserts that a world physically identical to ours but lacking phenomenal consciousness is conceivable; if such a world is possible, consciousness is not entailed by the physical. Critics of the knowledge argument, such as Lewis and Nemirow, claim that Mary gains only ability knowledge (knowing how to recognise, imagine, or remember red), not factual knowledge, so what she learns is not a new proposition. Others argue that physicalism can accommodate the new perspective as a representation of old facts under a different mode of presentation.
内格尔的“感受如何”论证坚称，无论多少客观的物理描述都无法捕捉经验的主观特征。要知道身为蝙蝠的感受如何，必须拥有蝙蝠的视角。类似地，查尔默斯的哲学僵尸论证主张，可以设想一个在物理上与我们的世界完全相同却毫无现象意识的世界；若这样的世界是可能的，则意识并非由物理事实必然导出。知识论证的批评者，如刘易斯和内米罗，主张玛丽获得的仅仅是能力知识（知道如何辨认、想象或记忆红色），而非事实知识，因此她学到的并非新的命题。另一些人则认为物理主义可以将新视角理解为同一旧事实在不同呈现方式下的表征。
9. Behaviourism and Mind-Brain Identity Theory | 行为主义与心脑同一论
Philosophical behaviourism analyses mental states in terms of observable behaviour or dispositions to behave. Ryle’s logical behaviourism rejects the ‘ghost in the machine’ and accuses dualism of a category mistake: it treats the mind as a non-physical thing that stands to the body as pilot to ship, whereas mental terms really refer to ways of acting. To say someone is thirsty is not to report an inner state but to describe a pattern of drinking behaviour. Hard behaviourism (Hempel) goes further, claiming that psychological statements are translatable without remainder into statements about bodily behaviour. Objections include the perfect actor (who exhibits all outward behaviour without the mental state) and the super-spartan (who has the mental state but suppresses all behavioural expression), showing that mental states cannot be reduced to behaviour alone.
哲学行为主义用可观察的行为或行为倾向来分析心理状态。赖尔的逻辑行为主义拒斥“机器中的幽灵”，指责二元论犯了范畴错误：将心灵当作与身体如舵手与船般对应的非物质之物，但心理词语实际指的是行为方式。说某人口渴，并非报告一种内部状态，而是描述喝水行为的模式。强硬行为主义（亨普尔）走得更远，主张心理陈述可以毫无剩余地翻译为关于身体行为的陈述。反例包括完美演员（展现出一切外在行为却不具有该心理状态）和超级斯巴达人（具有该心理状态却抑制一切行为表达），表明心理状态不能单独还原为
