在 Year 9 阶段，学生们开始接触一些人类有史以来提出过的最持久、最根本的问题。本指南涵盖了 Edexcel 哲学课程的核心主题，从哲学的本质、重要思想家，到关于上帝、心灵、伦理和自由意志的主要辩论。通过复习这些观念，你将为后续的哲学、伦理学和宗教研究打下坚实的基础。
1. What is Philosophy? | 什么是哲学？
The word ‘philosophy’ comes from the Greek words philo (love) and sophia (wisdom), so it literally means ‘the love of wisdom’. Philosophy is not just a subject you study at school; it is an activity of asking deep, fundamental questions about the world and our place in it.
“哲学”一词源自希腊语 philo（爱）和 sophia（智慧），因此其字面意思就是”爱智慧”。哲学不仅仅是在学校学习的一门学科，更是一种提出关于世界以及我们在其中所处位置的深刻根本问题的活动。
Philosophers try to think clearly and critically about questions that science alone cannot answer, such as: What does it mean to live a good life? How do we know what is real? Do we have free will? The aim is not always to find a single final answer, but to clarify the problems and evaluate different possible positions through reason and argument.
哲学家们试图清晰而批判性地思考那些科学无法独自回答的问题，例如：过美好生活意味着什么？我们如何知道什么是真实的？我们是否有自由意志？其目的并不总是找到一个单一的最终答案，而是澄清问题，并通过推理和论证来评估各种可能的立场。
2. Branches of Philosophy | 哲学的分支
Philosophy is a wide field, and it is traditionally divided into several main branches. Metaphysics explores the fundamental nature of reality, including questions about existence, time, space and causation. Epistemology is the theory of knowledge; it asks what we can know, how we know it, and what justifies our beliefs.
哲学是一个广阔的领域，传统上划分为几个主要分支。形而上学探究现实的基本本质，包括关于存在、时间、空间和因果律的问题。认识论是关于知识的理论，它追问我们能知道什么、我们如何知道，以及什么为我们的信念提供辩护。
Ethics, or moral philosophy, is concerned with how we should act, what is right and wrong, and what makes a good life. Logic studies the principles of correct reasoning, helping us to distinguish good arguments from bad ones. Other branches include aesthetics (the philosophy of art and beauty) and political philosophy (questions about justice, authority and rights).
伦理学，或道德哲学，关注我们应该如何行动，什么是正当与错误，以及什么造就美好人生。逻辑学则研究正确推理的原则，帮助我们区分好的论证与坏的论证。其他分支还包括美学（关于艺术与美的哲学）和政治哲学（关于正义、权威与权利的问题）。
3. Logic and Argument | 逻辑与论证
In philosophy, an argument is not a heated row but a structured set of statements intended to support a conclusion. The statements that give support are called premises. A deductive argument aims to provide conclusive proof: if the premises are true, the conclusion must be true. This is called a valid argument. If the argument is valid and all premises are actually true, it is sound.
在哲学中，论证不是一场激烈的争吵，而是一组旨在支持某个结论的结构化陈述。这些提供支持的陈述称为前提。一个演绎论证旨在提供决定性的证明：如果前提为真，结论必然为真。这称为有效论证。如果论证有效且所有前提事实上为真，它就是可靠的。
Inductive arguments, on the other hand, provide support that makes the conclusion probable but not certain. They move from specific observations to a general claim. For example, seeing many white swans and concluding all swans are white is inductive reasoning. Philosophers must also watch out for fallacies – common errors in reasoning, such as the ad hominem (attacking the person, not the argument) or the straw man (misrepresenting someone’s position to attack it easily).
另一方面，归纳论证提供的支持使得结论成为可能，但并不确定。它从具体的观察推向一般性主张。例如，看到许多白天鹅便得出所有天鹅都是白色的结论，这就是归纳推理。哲学家还必须警惕谬误——推理中常见的错误，如人身攻击（攻击人而非论证）或稻草人谬误（歪曲某人的立场以便更容易攻击）。
4. Socrates: The Father of Western Philosophy | 苏格拉底：西方哲学之父
Socrates lived in Athens from 469 to 399 BCE and is often called the father of Western philosophy. He did not write any books himself; what we know about him comes mainly from the dialogues written by his student Plato. Socrates spent his life questioning fellow citizens about concepts like justice, piety and courage.
苏格拉底于公元前469年至公元前399年生活在雅典，常被称为西方哲学之父。他本人没有写下任何著作；我们对他的了解主要来自他的学生柏拉图所写的对话录。苏格拉底一生都在向同胞们追问诸如正义、虔诚和勇气等概念。
His method, now called the Socratic method, involved asking a series of questions to draw out people’s hidden assumptions and reveal contradictions in their thinking. One of his most famous sayings is ‘The unexamined life is not worth living’. In 399 BCE, he was sentenced to death on charges of corrupting the youth and impiety. He accepted his punishment, choosing to obey the law rather than flee into exile.
他的方法，现在被称为苏格拉底方法，包括提出一连串问题，引出人们隐藏的假设，揭示其思维中的矛盾。他最著名的格言之一是”未经审视的人生不值得过”。公元前399年，他被指控腐化青年和不敬神而被判处死刑。他接受了惩罚，选择遵守法律而非流亡逃避。
5. Plato’s Theory of Forms | 柏拉图的理型论
Plato (427–347 BCE), a student of Socrates, developed one of the most influential ideas in Western philosophy: the Theory of Forms. According to Plato, the physical world we see around us is only a shadow or imperfect copy of a higher, non-physical realm of Forms. These Forms are perfect, eternal and unchanging archetypes of all things, such as the Form of Beauty, the Form of Justice and the Form of a Circle.
柏拉图（公元前427–347年），苏格拉底的学生，提出了西方哲学中最具影响力的思想之一：理型论。按照柏拉图的说法，我们周围的物理世界只是一个更高、非物理的理型世界之影子或不完满的摹本。这些理型是一切事物的完美、永恒且不变的范型，例如美之理型、正义之理型和圆形之理型。
Plato illustrates this with the famous Allegory of the Cave. In the story, prisoners are chained inside a cave, only able to see shadows projected on the wall. They mistake these shadows for reality. When one prisoner escapes and sees the real world and the sun, he realises the shadows were mere appearances. The escaped prisoner represents the philosopher who grasps the Forms, while the others represent ordinary people trapped in ignorance.
柏拉图通过著名的洞穴喻阐明了这一点。故事中，囚徒被锁在洞穴内，只能看到投射在墙上的影子。他们将这些影子错当成了现实。当一个囚徒挣脱束缚，看到真实的世界和太阳时，他才意识到那些影子仅仅是表象。逃脱的囚徒代表了把握理型的哲学家，其他人则代表了陷于无知中的常人。
6. Aristotle and Virtue Ethics | 亚里士多德与德行伦理学
Aristotle (384–322 BCE) studied at Plato’s Academy and later became the tutor of Alexander the Great. He rejected Plato’s Theory of Forms and instead focused on the world of experience. In ethics, Aristotle developed virtue ethics, which is not primarily about following rules or calculating consequences, but about cultivating good character.
亚里士多德（公元前384–322年）曾在柏拉图的学园学习，后来成为亚历山大大帝的老师。他拒斥柏拉图的理型论，转而关注经验世界。在伦理学上，亚里士多德提出了德行伦理学，它主要不是关于遵守规则或计算后果，而是关于培养良好的品格。
The key concept is the Golden Mean: every virtue lies at a balanced midpoint between two vices – one of excess and the other of deficiency. For example, courage is the mean between recklessness (too much fearlessness) and cowardice (too much fear). The ultimate goal of human life, according to Aristotle, is eudaimonia, often translated as ‘flourishing’ or ‘happiness’. This is achieved by living a life of rational activity in accordance with virtue.
其核心概念是中庸之道：每一种德行都处于两种恶习之间的平衡中点——一种是过度，另一种是不及。例如，勇敢是鲁莽（过度的无畏）和怯懦（过度的恐惧）之间的中道。根据亚里士多德，人类生活的终极目标是eudaimonia，常译为”兴盛”或”幸福”。这要通过过一种符合德行的理性活动的生活来实现。
7. The Existence of God – Arguments and Challenges | 上帝的存在——论证与挑战
Many philosophers and theologians have tried to prove that God exists. The ontological argument, first developed by Anselm, defines God as ‘that than which nothing greater can be conceived’. Anselm argues that such a being must exist in reality, because existing in reality is greater than existing only in the mind.
许多哲学家和神学家试图证明上帝存在。本体论论证，最初由安瑟伦提出，将上帝定义为”那无法设想出比之更伟大的存在者”。安瑟伦论证说，这样的存在者必须在现实中存在，因为存在于现实中比仅仅存在于心目中更伟大。
The cosmological argument, associated with Thomas Aquinas, points out that everything in the universe has a cause. There cannot be an infinite chain of causes, so there must be a First Cause or Prime Mover, which people call God. The teleological argument, or argument from design, presented by William Paley, compares the universe to a watch: its order and complexity suggest an intelligent designer.
宇宙论论证，与托马斯·阿奎那相关，指出宇宙中一切事物皆有原因。不可能存在无限的原因链条，因此必须有一个第一因或第一推动者，人们称之为上帝。目的论论证，或称设计论证，由威廉·佩利提出，将宇宙比作一块手表：其秩序和复杂性暗示着一位智慧的设计者。
However, these arguments face challenges. Critics ask ‘Who made God?’ in response to the cosmological argument. The theory of evolution by natural selection provides a non-theistic explanation for the complexity of life. The Big Bang theory gives an account of the origin of the universe without necessarily requiring a divine cause. Furthermore, the problem of evil questions whether a perfectly good God would create a world with so much suffering.
然而，这些论证面临着挑战。批评者针对宇宙论论证问道：”谁创造了上帝？”自然选择的进化论为生命的复杂性提供了一种非神论的解释。大爆炸理论解释了宇宙的起源，不一定需要一个神圣的原因。此外，恶的问题也质疑一位全善的上帝是否会创造这样一个充满苦难的世界。
8. The Problem of Evil | 恶的问题
The problem of evil is one of the most powerful arguments against the existence of an all-powerful, all-knowing and all-loving God. If God has the power to stop evil, the knowledge to know about it, and the desire to prevent it, why does evil still exist? Philosophers distinguish between moral evil (evil caused by human choices, such as murder or cruelty) and natural evil (suffering caused by natural events, like earthquakes or diseases).
恶的问题是对全能、全知、全爱的上帝存在最强有力的反驳之一。如果上帝有力量制止恶，有知识知晓恶，并有意愿阻止恶，为什么恶依然存在？哲学家区分了道德恶（由人类选择造成的恶，如谋杀或残忍行为）和自然恶（由自然事件引起的苦难，如地震或疾病）。
Several theodicies have been proposed to explain why a good God allows suffering. The free will defence argues that God gave humans free will so that they could genuinely love and choose good. Without the possibility of choosing evil, free will would be meaningless, and a world with free will is more valuable than one without it. Therefore, moral evil results from the misuse of free will.
人们提出了一些神义论来解释为何一位善的上帝会容许苦难。自由意志辩护论证说，上帝赋予人类自由意志，以便他们能够真正地去爱和选择善。如果没有选择恶的可能性，自由意志将毫无意义，而一个拥有自由意志的世界比没有的世界更有价值。因此，道德恶是滥用自由意志的结果。
Another response is the soul-making theodicy, developed by John Hick. It suggests that suffering and hardship are necessary for spiritual growth. Facing challenges helps humans develop virtues such as courage, compassion and patience. In this view, life is a process of character building, and evil is a tool that makes moral improvement possible.
另一种回应是约翰·希克提出的灵魂塑造神义论。该理论认为，苦难和艰辛对于灵性成长是必要的。面对挑战有助于人类培养勇敢、同情和耐心等美德。按照这种观点，人生是一个品格塑造的过程，而恶是使得道德提升成为可能的工具。
9. Mind and Body: Dualism vs Materialism | 心灵与身体：二元论与唯物主义
One of the central puzzles in philosophy is the relationship between the mind and the body. Are they two completely different substances, or is the mind simply the product of physical brain activity? The view known as substance dualism, famously defended by René Descartes, holds that the mind is a non-physical thinking substance, while the body is a physical extended substance. They interact, but are distinct.
哲学中的核心谜题之一是心灵与身体之间的关系。它们是两种完全不同的实体，还是说心灵仅仅是物理大脑活动的产物？被称为实体二元论的观点，由勒内·笛卡尔著名地予以辩护，主张心灵是一种非物理的思考实体，而身体是物理的广延实体。它们相互影响，但各自独立。
In contrast, materialism (or physicalism) claims that everything that exists is physical, including the mind. Mental states, such as pain or happiness, are nothing over and above brain states. From this perspective, consciousness is simply what the brain does, much like breathing is what the lungs do.
与此相对，唯物主义（或物理主义）声称一切存在都是物理的，包括心灵。心理状态，如疼痛或快乐，无非就是大脑状态。从这个角度看，意识只是大脑的活动，就像呼吸是肺的活动一样。
A major difficulty for materialism is the ‘hard problem of consciousness’: why and how do physical processes in the brain give rise to subjective, first-person experience? We can explain how the eye detects light, but why is seeing a sunset accompanied by a vivid feeling? This remains an open question in philosophy and science.
唯物主义面临的一个主要困难是”意识的难题”：大脑中的物理过程为什么以及如何产生主观的第一人称体验？我们可以解释眼睛如何探测光线，但为什么看到日落会伴随一种生动的感受？这在哲学和科学中仍然是一个悬而未决的问题。
10. Free Will and Determinism | 自由意志与决定论
Do we genuinely choose our actions, or are all our decisions determined by prior causes? This is the classic debate over free will and determinism. Determinism claims that every event is the inevitable result of previous causes, according to the laws of nature. If the universe operates like a great mechanism, then human choices are no exception – they are simply one link in an unbroken causal chain.
我们是真的在选择自己的行动，还是说我们所有的决定都是由先前的原因决定的？这便是关于自由意志与决定论的经典辩论。决定论声称，按照自然规律，每一个事件都是先前原因的必然结果。如果宇宙像一台巨大的机器一样运行，那么人类的选择也不例外——它们只是不间断的因果链条中的一环。
If determinism is true, it raises troubling questions about moral responsibility. If a person’s actions are predetermined by their genes, upbringing and environment, can we really hold them blameworthy or praiseworthy? Some philosophers, called hard determinists, accept that determinism rules out free will and therefore call for a revision of our ideas of punishment and reward.
如果决定论为真，这便引发了关于道德责任的棘手问题。如果一个人的行为是由其基因、成长背景和环境预先决定的，我们真的能对他们进行责备或表扬吗？一些被称为强硬决定论者的哲学家承认，决定论排除了自由意志，因此呼吁修正我们关于惩罚与奖赏的观念。
Libertarians in philosophy argue that we do have free will and that determinism is false. They appeal to our powerful intuition that we could have done otherwise when making a choice. Compatibilism, also called soft determinism, seeks a middle ground: it says that free will and determinism are compatible. We are free as long as our actions flow from our own desires and character, even if those desires are themselves caused by prior factors.
哲学中的自由意志论者则主张我们确实拥有自由意志，并且决定论是错误的。他们诉诸于我们强烈的直觉：在做出选择时，我们本可以做出不同的决定。相容论，也叫弱决定论，寻求一条中间道路：它认为自由意志与决定论是相容的。只要我们的行动是源自我们自身的欲望和品性，我们就是自由的，即便这些欲望本身也是由先前的因素造成的。
