1. Plato's Allegory of the Cave | 柏拉图的洞穴寓言
Question: Explain the main message of Plato's Allegory of the Cave and what it suggests about the nature of reality. (8 marks)
问题：解释柏拉图洞穴寓言的主要信息及其对实在本质的启示。（8分）
Plato describes prisoners chained in a cave since childhood, only able to see shadows projected on the wall from puppets manipulated behind them. The prisoners mistake these shadows for reality, just as most people trust sensory appearances without questioning them.
柏拉图描述了一群从小就被锁在洞穴中的囚徒，他们只能看到身后木偶被操纵而投射在墙上的影子。囚徒们把这些影子误认为现实，正如大多数人只相信感官表象而不加质疑。
When one prisoner is freed and forced to climb out of the cave, he is initially blinded by the sunlight and struggles to see the real objects. Gradually, he acclimates and can look at the moon, stars, and eventually the sun itself. This journey symbolises the philosopher's ascent from the world of appearances (the visible realm of becoming) to the intelligible realm of Forms, with the Form of the Good represented by the sun, the ultimate source of truth and knowledge.
当一名囚徒被释放并被迫走出洞穴时，他最初被阳光刺眼，难以看到真实物体。渐渐地，他适应了，能够看到月亮、星星，最终直视太阳本身。这段旅程象征着哲学家从表象世界（可见的生成领域）上升到可知的理型世界，其中“善的理型”由太阳代表，是真理和知识的终极源泉。
The freed prisoner feels compelled to return and free the others, but they mock him and resist. This illustrates the philosopher's duty to enlighten society and the difficulty of challenging popular beliefs. Plato's allegory teaches that true reality is not found in the ever-changing physical world but in the permanent, abstract Forms grasped through reason.
获释的囚徒感到必须返回去解放其他人，但他们嘲笑他并抗拒。这说明了哲学家有责任启蒙社会，以及挑战世俗观念的困难。柏拉图的寓言教导我们，真正的现实并不在变动不居的物理世界，而在于通过理性把握的永恒、抽象的理型。
2. Descartes' Method of Doubt | 笛卡尔的怀疑方法
Question: How does Descartes use the method of doubt to question the reliability of our senses? Include reference to the dream argument. (6 marks)
问题：笛卡尔如何运用怀疑方法来质疑感官的可靠性？请提及梦境论证。（6分）
Descartes aimed to build a secure foundation for knowledge, so he resolved to doubt anything that could be doubted in the slightest. He started by attacking the senses, noting that they sometimes deceive us — for example, a straight stick appears bent in water, and distant towers look small. If our senses have deceived us once, we cannot trust them completely.
笛卡尔旨在为知识建立一个稳固的基础，于是他决心怀疑任何可以怀疑的事物。他首先攻击感官，指出感官有时会欺骗我们——例如，直棍浸在水中看起来是弯的，远方的塔看起来很小。如果感官曾欺骗过我们，我们就不能完全信任它们。
The dream argument expands this doubt: when dreaming, we often have vivid experiences indistinguishable from waking life. Therefore, at any given moment, we cannot be absolutely sure we are not dreaming. This possibility undermines all knowledge based on sensory experience, including the existence of our own bodies and the external world.
梦境论证扩展了这种怀疑：在梦中，我们常常有与清醒时难以区分的生动体验。因此，在任何时刻，我们都不能绝对确定自己不在梦中。这种可能性动摇了所有基于感官经验的知识，包括我们自身躯体和外部世界的存在。
Descartes even supposes a malicious demon could deceive him about mathematical truths. However, the very act of being deceived proves his existence; hence the famous conclusion 'I think, therefore I am' (Cogito, ergo sum). This method shows that sensory knowledge is uncertain, while rational introspection yields at least one indubitable truth.
笛卡尔甚至假定一个邪恶的魔鬼可能在数学真理上欺骗他。然而，被欺骗这一行为本身就证明了他的存在；因此有了著名的结论“我思故我在”。这种方法表明，感官知识是不确定的，而理性内省至少能产生一个不容置疑的真理。
3. The Teleological (Design) Argument | 目的论（设计）论证
Question: Outline William Paley's design argument and explain one criticism of it. (8 marks)
问题：概述威廉·佩利的设计论证，并解释对此的一个批评。（8分）
William Paley presents the watchmaker analogy: if you found a watch while walking on a heath, you would immediately recognise that its intricate parts were arranged for the purpose of telling the time, and you would infer a watchmaker. The universe, Paley argues, exhibits even greater complexity and purpose — the human eye, the orbits of planets, the laws of physics — which points to a divine designer, God.
威廉·佩利提出了钟表匠类比：如果你在荒野散步时发现一块手表，会立刻意识到其精密零件是为显示时间这一目的而组合的，并推论出有一位钟表匠。佩利认为，宇宙展现出甚至更复杂的秩序和目的——人的眼睛、行星的轨道、物理法则——这些都指向一位神圣设计者，即上帝。
This argument is a posteriori, based on observation of the natural world. It uses analogical reasoning: just as a watch implies a watchmaker, so the cosmos implies a cosmic designer.
该论证是后验的，基于对自然界的观察。它运用类比推理：正如手表意味着钟表匠，宇宙也意味着一位宇宙设计者。
