Good Will and Duty

Chapter 1 opens with one of the most quoted sentences in all of moral philosophy. Nothing in the world, Kant says, can be conceived as good without qualification except a good will.

Start with what this claim is responding to. Most of the things we call "good" are only good under certain conditions. Intelligence is good, but a clever criminal uses intelligence to do terrible things; there the intelligence makes him worse, not better. Courage is good, but a courageous bank robber is harder to stop than a cowardly one. Wealth, power, health, good luck: all of these are good in the right hands, and harmful in the wrong ones. Even happiness, Kant says, is not unconditionally good. We would feel something is wrong if we saw a cruel and wicked person flourishing happily; the happiness of the wicked is a kind of moral affront. None of these goods is good in itself.

The good will is different. A good will is good no matter what. It is good even if it fails in its aim, even if circumstances prevent it from accomplishing anything at all. Kant puts this in a striking image: the good will would "like a jewel, still shine by its own light as something that had its full worth in itself" even if external conditions stripped it of everything else.

What is a good will, then? For Kant, it is not a disposition or a feeling or a personality trait. It is a particular way of choosing: the will of someone who does what is right because it is right, not because it happens to produce some further benefit. A good will wills the good for its own sake. Everything else we call "good" is conditionally good, good if put to the right use; the good will is unconditionally good, because it is the faculty that puts other things to their right use.

This is already a striking claim. Kant is saying that the seat of moral value is not results, or outcomes, or happiness, but something internal to the agent: what she wills, and why she wills it.

To clarify what a good will is, Kant introduces one of his most important distinctions: the difference between acting from duty and acting in accordance with duty.

Consider Kant's famous shopkeeper. A shopkeeper who never cheats his customers is doing the right thing, but why does he do it? Perhaps because cheating is bad for business. Perhaps because he fears being caught. Perhaps because an honest reputation draws customers. In any of these cases, the shopkeeper's honesty is produced by self-interest rather than by his recognition that cheating is wrong. He does the right thing, but not because it is the right thing.

Such action is "in accordance with duty." The shopkeeper's behavior conforms to what duty requires, but his motive is not duty. Kant's point is that this is not really moral action in the fullest sense. If self-interest happened to point the other way, the shopkeeper would cheat. His honesty is an accident of circumstance.

Compare this with action "from duty": action done because duty requires it, regardless of whether self-interest or inclination happens to line up. A shopkeeper who refuses to cheat because cheating is wrong (full stop) acts from duty. She would refuse to cheat even if she could get away with it, even if it would make her rich, even if no one would ever know.

Kant gives several examples to make the distinction vivid. The one that often sticks with students is the case of the friend. Someone who is naturally warm and sympathetic does kind things for their friends because they enjoy it; their kindness flows from temperament. Kant thinks this kindness has no moral worth. It is morally nice, but it is not moral in the sense that matters. Contrast this with someone whose natural temperament is cold, who feels no particular warmth toward others, but who still acts kindly because kindness is the right thing to do. This second person's action has moral worth in a way the first person's does not. The first person's kindness would vanish if their mood changed; the second person's kindness is not at the mercy of mood.

This conclusion strikes many first-time readers as strange or even objectionable. Isn't the warm, naturally generous person better than the cold person who has to force himself to be kind? It is worth pausing on this reaction. Kant's point is not that the warm person is bad. It is that what makes an action morally worthy is not the feeling behind it but the recognition of the right and the will to act on it. Feeling can align with duty or diverge from it; it is duty itself, recognized and chosen, that is the source of moral worth.

If acting from duty is what gives an action moral worth, Kant needs to say something more about what duty is. His answer, worked out across the middle paragraphs of Chapter 1, is that duty is reverence for the moral law.

Notice what Kant is not saying. He is not saying duty is what society tells you to do, or what your upbringing imposed on you, or what your conscience happens to whisper. Those are all particular duties, tied to particular cultures and circumstances. Kant is after something more fundamental: the form of duty as such. What makes any particular duty a duty?

His answer is that to act from duty is to act out of respect for a law: a principle you recognize as binding independently of your own inclinations. When you act because the law requires it, and you will what it requires simply because the law requires it, you are acting from duty.

This is still abstract. What law? Kant hints at the answer at the end of Chapter 1 with a preliminary formulation of what will become the categorical imperative. He says: the only thing left for a will that acts from duty is the universality of law itself. If I am going to act from duty, without reference to any particular content or inclination, the only principle available to me is a principle of lawfulness as such. I must act on principles that could count as laws for everyone.

Chapter 1 ends with a first rough statement: "I should never act in such a way that I couldn't also will that the maxim on which I act should be a universal law." This is the thin edge of the wedge. Chapter 2 will take this rough formulation and develop it into the categorical imperative, with several more precise formulations and a fuller explanation of how it is supposed to work.

One of the most striking features of Chapter 1 is what Kant does not appeal to. He never grounds morality in what human beings are like. He does not say that we are social animals, or rational animals, or creatures with certain natural inclinations. All of that would be empirical: it would tell us about what humans happen to be, and the moral principles derived from it would apply only to creatures like us.

Kant thinks this is the wrong foundation for morality. Recall that Aquinas derived moral precepts from our natural inclinations: self-preservation, reproduction, life in community, the pursuit of truth. Kant would say that this approach makes morality contingent on the facts about human nature. If humans were different, the precepts would be different. But then the precepts cannot have the kind of authority Kant thinks morality requires: they cannot be binding on every rational being as such.

Kant's ambition is larger. He wants moral principles that would hold not just for humans but for any rational being whatsoever: for angels, for aliens, for any creature capable of reasoning. The only way to get principles with that kind of universal scope is to derive them from reason itself, not from the contingent features of the kind of creature that happens to be doing the reasoning.

This is also why Kant is so suspicious of happiness as the foundation of morality. Happiness is empirical: it is a psychological state that different people achieve in different ways, depending on what they want. A morality built on happiness would tell us to pursue whatever leads to happiness, but what leads to happiness varies with desires, and desires vary with individuals. Such a morality gives us no fixed principles at all.
