Ethics

Sen ts’an | Philosophical Terms | Teleology | Philosophers to Study

The core idea in plain words

Ethics is the part of philosophy that asks one stubborn question: how should I live, and what do I owe other people? Not “what is legal”, not “what is polite”, not “what do most people do” — but what is actually right, and why.

Every day you answer that question without noticing. You decide whether to tell a friend the truth about their bad idea, whether to keep money you found, whether to eat the meat, whether to keep a promise when it has become inconvenient. Ethics is simply doing that thinking out loud, carefully, and checking whether your answers hang together.

An analogy: the three navigators

Picture a ship crossing a dark sea with three navigators arguing over the chart.

• The first says: steer by the destination. Whatever gets the most people safely to port is the right course. That is consequentialism — judge an act by its results. Jeremy Bentham put it as “the greatest happiness of the greatest number”.
• The second says: steer by the rules of the sea. Some things you never do — you never throw a passenger overboard, even if it lightens the ship and saves ten others. That is deontology — duties and rights that hold regardless of the payoff. Kant is the great name here: act only on a rule you could will to be a law for everyone, and never treat a person merely as a tool.
• The third says: steer by being a good captain. Rules and sums only get you so far; what you need is a person of courage, honesty and practical wisdom who sees what the moment calls for. That is virtue ethics, which goes back to Aristotle, and in a different key to Epicurus, who thought the good life was a calm, simple, friendly one.

Real navigators use all three. So do real people. The interesting cases are the ones where the three disagree.

A worked example: the broken promise

You promised to help a friend move house on Saturday. On Friday night, a stranger’s car breaks down outside your home and they need a lift to the hospital with a sick child — Saturday morning, the same time.

Run it through the three navigators:

1. Consequences. The child’s health outweighs a few hours of box-lifting. Your friend can find someone else or move a little later. Go to the hospital.
2. Duties. You have a duty to keep promises, but also a duty of rescue when the cost to you is small and the harm prevented is large. Duties can conflict; most deontologists rank preventing serious harm above a minor promise. Go to the hospital — and phone your friend tonight, because the duty to the promise does not vanish, it turns into a duty to explain and make amends.
3. Virtue. What would a kind, honest, reliable person do? They would help the child, and they would not ghost the friend. They would turn up next weekend with pizza.

Notice that all three land in roughly the same place, but they give different reasons, and the reasons tell you what else you owe. That is the practical value of ethics: it doesn’t just pick an action, it shows you the full shape of your obligations.

Now change one detail: the “emergency” is that a stranger wants a lift to the airport because they overslept. The consequentialist sum shrinks, the duty of rescue disappears, and the virtuous person keeps the promise. Small changes in facts, big changes in what is right — which is why ethics is a skill and not a lookup table.

Common misconceptions

• “Ethics is just opinion.” Tastes differ, but ethical claims come with reasons, and reasons can be good or bad. “Cruelty for fun is wrong” is not on the same level as “I prefer tea”.
• “Ethics is the same as religion.” Religions carry ethical teachings, but the arguments of Aristotle, Kant or Bentham stand on their own. You can test them without any creed.
• “Ethics is the same as the law.” Slavery was legal. Hiding refugees was illegal. The law is what a society enforces; ethics is what it should enforce.
• “If people disagree, there’s no answer.” People disagree about physics too. Disagreement means the question is hard, not that it is empty.
• “Good intentions are enough.” Intentions matter, but so do consequences you could have foreseen. “I meant well” is the beginning of an excuse, not the end of one.

The Zen angle

I keep Sen Ts’an at the top of this page on purpose. His line “Do not like, do not dislike; all will then be clear” sounds like the opposite of ethics, which is all about picking and choosing. But read it as a warning rather than a rule: much of our moral confusion comes from clinging — to being right, to our tribe, to our comfort. When the grasping quietens, it is often surprisingly obvious what the kind thing to do is. The Western theories give you the map; the Eastern traditions tell you to clean your glasses before reading it.

Connections

• Teleology — Aristotle’s virtue ethics rests on the idea that things have a purpose (telos), and a good human life is one that fulfils ours.
• Philosophical Terms — normative, descriptive, meta-ethics, and the rest of the vocabulary.
• Friedrich Nietzsche — the great critic of morality, who asked where our values came from and whether they deserve our loyalty.
• Jordan B Peterson — responsibility as the core of a meaningful life.
• The Righteous Mind — Jonathan Haidt on why good people are divided by politics and religion, and why moral intuition comes before moral reasoning.
• Jeremy Bentham and Epicurus — pleasure, pain and the calculation of happiness.

How to practise

Pick one decision this week that bothers you a little. Write down what each of the three navigators would say. If they agree, act and stop worrying. If they disagree, you have found a real ethical question — and that is where the interesting part of life is.
