Chapter I: Analytic of the Principles of Pure Practical Reason

简要导读 (中英文对照)

中文：

这一章的核心是区分“实践理性”与“经验动机”。康德认为，道德行为并不是因为追求快乐或避免痛苦，而是因为遵循“纯粹实践理性”的原则。

他提出“定言令式”作为最高的实践原则：“你只应当依照你也能够希望它成为普遍法则的准则去行动。”

换言之，道德法则不是依靠外在的功利，而是内在的必然性。

English:

The core of this chapter is to distinguish “practical reason” from “empirical motives.” Kant argues that moral action is not driven by the pursuit of pleasure or the avoidance of pain but by the principles of pure practical reason.

He introduces the “Categorical Imperative” as the supreme principle of practice: “Act only according to that maxim whereby you can at the same time will that it should become a universal law.”

In other words, the moral law does not rely on external utility but on inner necessity.

核心要点 (Key Points)

• 道德律的普遍性 (Universality of the moral law)
• 行为动机的纯粹性 (Purity of moral motivation)
• 自由与自律的前提 (Freedom and autonomy as presuppositions)

问答 (Q&A)

Q1 中文：康德为什么否定“快乐”作为道德的基础？

A1 中文：因为快乐是经验性的，不具备普遍必然性，不能成为道德律的根基。

Q1 English: Why does Kant reject “pleasure” as the basis of morality?

A1 English: Because pleasure is empirical and lacks universal necessity; it cannot serve as the foundation of the moral law.

Q2 中文：什么是“定言令式”？

A2 中文：它是实践理性的基本原则，要求行为准则必须可以普遍化。

Q2 English: What is the “Categorical Imperative”?

A2 English: It is the fundamental principle of practical reason, requiring that maxims of action must be capable of universalization.

Q3 中文：这一章如何体现自由？

A3 中文：因为只有当人被视为自由的存在者时，他才可能遵循道德律，而不是受自然欲望支配。

Q3 English: How does this chapter relate to freedom?

A3 English: Because only if man is regarded as free can he follow the moral law, rather than being governed by natural inclinations.
