Do You Just Know What's Right? Harold Prichard Said So
The Promise You Just Know You Ought to Keep
Imagine you borrowed your friend’s favourite jacket and promised to return it tomorrow. Tomorrow comes, but you really want to keep wearing it. You might start listing reasons: your friend has other jackets, you’ll give it back next week, it’s not a big deal. Yet somewhere inside, a voice says: you ought to return it, because you promised. No argument, no calculation — just a quiet, undeniable sense.
Harold Prichard (1871–1947), a shy Oxford professor, believed that this inner voice is exactly how we know what’s right. He didn’t think you could ever prove why you should keep a promise by pointing to good results or big moral theories. For Prichard, some moral truths are just obvious — you recognise them directly, without any extra reasoning. The whole job of moral philosophy, he wrote, was not to prove what you ought to do, but to remind you to pay attention to what you already know.
A Professor Who Hated Publishing and Loved Tennis
Prichard was not your usual philosophical celebrity. He published almost nothing: one book on Kant’s theory of knowledge, a handful of articles, and that was it. When a fellow teacher died, he praised him partly because his students had “refrained from writing” too. Prichard believed that some deep truths are so basic that trying to explain them with a theory actually makes things worse.
His teacher, John Cook Wilson, had convinced him that knowledge is a weird thing: you can’t define it in terms of anything else. Knowledge is just knowledge — it’s sui generis, meaning it belongs to its own unique category. If you try to break it down into smaller pieces, you end up describing something that isn’t knowledge. Prichard applied the same idea to moral obligation, the feeling that you ought to do something. He said moral obligation is also sui generis. No amount of talk about happiness, outcomes, or rules can ever capture what it means to be obliged to act.
When the famous philosopher Ludwig Wittgenstein visited Oxford, Prichard kept interrupting him, deliberately mispronouncing his name. Wittgenstein finally snapped back harshly. Prichard didn’t care about looking polite. He cared about what you could honestly claim to know, and he spent his career insisting that most ethical theories were trying to answer the wrong questions.
Can Good Results Tell You What to Do?
Many people think the right action is the one that brings the best results. If an act has good consequences, you ought to do it — that’s the heart of utilitarianism. Prichard saw a big problem there. He invited readers to test their own minds. Suppose you owe someone money. Do you feel that you ought to repay because it will bring good into the world? He answered, “we at once and without hesitation answer ‘No’.” The sense of duty comes straight from the fact that you borrowed and promised, not from a calculation of future happiness.
He gave a clever example to sharpen the point. Imagine that it would be good if your rich uncle donated money to a hospital. You could write him a letter asking him to give. The result of writing would be something good. Does it follow that you must write the letter? Prichard said absolutely not. The word good just describes a state of affairs; it doesn’t carry any “you ought to” force inside it. If you say, “That would be good, so I ought to do it,” you’re secretly smuggling in an extra rule that goodness creates commands. But goodness isn’t a commander, and you can’t pull an ought out of a good without cheating.
For Prichard, moral obligation doesn’t live in the future consequences of an act. It lives in the specific nature of the act and the relationship you have to the people involved — like being the one who gave a promise, or being a parent to a child. Those concrete facts, and nothing else, make up the ground of your duty.
Kant’s Impossible Demand
Prichard’s other big target was Immanuel Kant (1724–1804). Kant held that an action is morally good only if it is done from the motive of duty — not because you feel like helping, but because you recognise that it is the law for all rational beings. Prichard thought this was a disaster. He argued that you cannot have an obligation to act from a particular motive because you cannot simply choose your motives by force of will. If you are afraid of dogs, you can’t just decide to feel brave; you either feel it or you don’t. If Kant was right, Prichard said, we would be required to feel something we can’t control. That makes no sense as a duty.
Prichard went further. If your only duty is to act from the motive of duty, then you never actually have a duty to do any specific thing — like returning the jacket. Your only job would be to have a certain feeling while you act. But then, Prichard asked, what is the feeling about? It can’t be about a specific duty, because no specific act is required. The whole theory, he concluded, collapses under its own weight.
Many philosophers believe Prichard read Kant unfairly. Kant did not say an act is right only if done from duty; he said it has moral worth only then. Still, Prichard’s sharp challenge forced everyone to think harder about what exactly we owe each other and whether our inner feelings have anything to do with it.
The Ought That Lives in You
Late in his life, Prichard changed his mind about where obligation actually sits. At first, he talked about rightness as if it were a property of the action itself, like the colour of a bike. But then he saw a puzzle. If you have a duty to do something tomorrow — like returning the jacket — that duty exists right now, before the action does. How can a property belong to an action that doesn’t yet exist? He concluded that obligation is really a property of the agent, the person who must act. It’s not that “returning the jacket is obligatory”; it’s that “you are obliged to return it.”
This isn’t just a tiny tweak. It means that when you sense a moral duty, you’re sensing something about yourself — a claim on you to act a certain way. No theory can hand you that awareness. You have to step into the situation (or imagine it strongly) and let your moral thinking do its work. Prichard said, “the only remedy lies in actually getting into a situation which occasions the obligation.” Moral philosophy, he insisted, can’t manufacture that feeling for you.
He also quietly abandoned his earlier idea that you have a special “sense of obligation” as a separate motive. By the end, he believed every action needs a desire, and the feeling of duty only moves you if you already want to do what you ought. That opened up a whole new debate about whether knowing what’s right has any built-in pull on your choices.
Why Your Quiet Certainty Still Bothers Philosophers
Prichard’s view can be deeply attractive. When you really think about it, you probably do feel that some things are just wrong — hurting someone for fun, breaking a promise for no reason — regardless of the consequences or any grand system. That direct moral sense is something children often feel long before they hear about ethical theories. Prichard gave that feeling a philosophical home.
But his position also makes many thinkers uncomfortable. If moral truths are just obvious to anyone who looks, why do people disagree so much about right and wrong? Prichard would say that we haven’t paid proper attention to the right features of the situation, or that we’re letting other thoughts get in the way. Critics reply that this is too easy an answer, and that a world without arguments to back up our duties feels a bit like making moral claims that can’t be checked.
Still, Prichard left a lasting mark. He made it impossible to ignore the possibility that some moral knowledge is basic, like knowing that two plus two is four. His quiet, stubborn work reminds you that when you face a tough choice, the most powerful tool you have is not a theory — it’s the act of paying careful attention to what’s right in front of you.
Think about it
- Can you think of a time when you just knew something was wrong, even though you couldn’t explain why? What made you so sure?
- If a friend says, “The only reason not to steal is that you’ll get caught,” could you prove them wrong without appealing to any feelings? Why or why not?
- Do you believe there are some rules that are right no matter what the consequences are? Give an example and explain why you think it holds.
