Kant had a radical idea: some things are just wrong. Period.
Not wrong because they lead to bad outcomes. Not wrong because they make people unhappy. Wrong because of what they are.
Most ethical theories care about results. Utilitarianism says maximize happiness. Hedonism says pursue pleasure. But Kant said forget the consequences. Focus on the action itself.
His example: lying is always wrong. Even if lying would save someone’s life, it’s still wrong to lie. The rightness or wrongness lives in the action, not in what happens after.
This sounds crazy until you think about it. We already act this way sometimes.
You probably think murder is wrong even if it made the world happier. You probably think keeping promises matters even when breaking them would be more convenient. You have intuitions that some rules shouldn’t be broken, regardless of the outcome.
Kant tried to systematize this feeling. He called it the categorical imperative: act only according to rules you could will to be universal laws.
Would you want everyone to lie whenever they thought it might help? No. So don’t lie.
Would you want everyone to break promises when it suited them? No. So keep your promises.
The appeal is obvious. It gives you clear rules. It treats people as ends in themselves, not just tools for producing good outcomes.
The problem is also obvious. Sometimes following the rules leads to terrible results.
I find myself torn. Consequences matter. But so does treating people with dignity, which sometimes means following rules even when it hurts.
Maybe that tension is the point.
