重点摘要
1. 道德作为社会合作的生存机制演化而来
“人类的道德情感和人类群体的道德原则主要通过自然选择对个体的作用而演化，其次通过群体选择对种群的作用而演化。”
演化起源。 道德作为一种适应性特征在早期人类社会中出现，促进了合作与群体凝聚力。这种道德意识经过数十万年的发展，因其为能够有效合作的群体带来的生存优势而不断演化。
社会纽带。 同情、内疚和羞耻等道德情感的演化旨在强化合作行为，抑制可能危害群体的自私行为。这些情感帮助建立社会纽带和信任，使得更大、更复杂的社会得以形成。
道德的规范化。 随着人类社会的日益复杂，非正式演化而来的道德原则被纳入宗教和文化体系中。这一规范化过程有助于跨代传递道德价值观，并在更大的人口中维持社会秩序。
2. 人类同时具备道德和非道德倾向
“人类本质上既是道德的也是非道德的，既是善良的也是邪恶的，既是利他的也是自私的，既是合作的也是竞争的，既是和平的也是好战的，既是有德的也是无德的。”
双重本性。 我们的进化历史赋予了我们道德和非道德行为的能力。这种双重性反映了人类进化过程中复杂的社会环境，在不同情况下，不同的策略可能具有优势。
情境道德。 道德或非道德行为的表现高度依赖于情境。以下因素均可影响个体在特定情况下的道德或非道德行为：
- 社会环境
- 文化规范
- 个人境遇
- 感知到的威胁或机会
道德灵活性。 这种内在的道德灵活性使人类能够适应广泛的社会环境和挑战。然而，这也意味着即使是通常道德的人在特定情况下也可能表现出非道德行为，正如米尔格伦的服从实验所示。
3. 自由意志存在于决定论的约束之中
“我们是自由的道德代理人，对自己的行为负责，因为我们无法完全了解决定我们个人生活的近乎无限的因果网络。”
兼容论。 尽管我们的行为受到遗传、环境和历史因素的影响，但这些影响的复杂性为有意义的选择创造了空间。这一观点调和了决定论与自由意志之间的表面冲突。
道德责任。 由于我们无法完全预测或理解影响我们决策的所有因素，我们必须假设自己拥有自由意志。这一视角允许道德责任的存在，并为个人成长和改变提供了可能性。
实际意义：
- 基于个人责任的法律体系
- 鼓励道德行为的社会规范
- 个人努力提升自我和做出更好选择
4. 临时伦理在绝对主义与相对主义之间取得平衡
“道德原则是临时真实的——也就是说，它们适用于大多数人、大多数文化和大多数情况下的大多数时间。”
中间立场。 临时伦理提供了一种在道德绝对主义的僵化与道德相对主义的潜在混乱之间的平衡方法。它承认道德原则可以广泛适用，而不必是普遍或不变的。
灵活性与稳定性。 这种方法允许道德指导原则：
- 足够稳定，以提供社会凝聚力和个人指导
- 足够灵活，以适应变化的环境和新信息
- 基于证据和理性论证开放修订
实际应用。 临时伦理鼓励对道德问题进行批判性思考，同时仍提供决策框架。它承认现实世界情境的复杂性，同时努力追求一致的伦理原则。
5. 科学可以为道德决策提供信息
“科学可以阐明一个答案，或者至少许多可以根据证据确认或否定的可检验答案。”
基于证据的伦理。 心理学、神经科学和人类学等领域的科学研究可以为人类行为和道德决策提供宝贵的见解。这种实证方法有助于将伦理讨论建立在事实观察的基础上。
道德心理学。 关于人类如何实际做出道德决策的研究可以丰富我们对伦理的理解。关键发现包括：
- 情感在道德判断中的作用
- 认知偏见对伦理推理的影响
- 社会背景在塑造道德行为中的重要性
不断演变的理解。 随着科学知识的进步，我们对道德的理解可以得到细化和改善。这使得伦理体系能够适应新信息和变化的社会条件，就像科学理论根据新证据进行更新一样。
6. 容忍与贸易促进和平与繁荣
“商品不跨越国界，军队就会。”
经济相互依赖。 个人和国家之间的贸易创造了共同利益，减少了冲突的可能性。这种经济互联性可以促进不同群体之间的合作与理解。
交换的好处：
- 通过专业化和效率提高繁荣
- 文化交流与多元视角的接触
- 形成共同利益，抑制暴力冲突
神经基础。 科学研究表明，包括贸易在内的合作行为刺激大脑的奖励中心。这种神经强化有助于解释为何贸易与合作在社会中如此成功。
7. 怀疑主义与世俗伦理提供前进的道路
“怀疑的美德在于找到平衡。”
理性探究。 怀疑主义，定义为深思熟虑的探究，为批判性审视道德主张和信念提供了一种方法。这种方法有助于识别和挑战伦理推理中的无根据假设。
世俗基础。 基于理性和实证观察的世俗伦理方法可以提供更具普遍适用性的道德框架。这使得伦理讨论能够超越特定的宗教或文化传统。
关键原则：
- 开放的心态与批判性思维的平衡
- 基于新证据修正信念的意愿
- 强调人类繁荣与福祉作为伦理目标
实际意义。 采用怀疑和世俗的伦理方法可以促进更大的宽容，促进跨文化对话，并推动基于证据的政策，以提升人类福祉。
