── Picturing the three great schools of ethics as three regulars at the cafe ──
Cast — three cafe regulars
The story ── one rainy afternoon, at Cafe Socrates
1. Three regulars
Cafe Socrates ── a tiny place tucked in a backstreet of Shinjuku, Tokyo. On a rainy afternoon, three regulars sat reading at separate tables.
- A white-haired gentleman with a black cane ── Professor Kant
- A middle-aged man scribbling calculations in a notebook ── Professor Mill
- A bearded old man with a stack of five books beside him ── Professor Aristotle
Three different philosophies — and somehow regulars at the same cafe. They nod when their eyes meet, but rarely strike up a debate. Not yet.
2. A young customer enters
The glass door swung open, and a young woman, probably a high-school student ── Mai ── stepped in.
The barista, who had a packed register, said "Right away!" and disappeared into the back. And then, in the rush, the barista accidentally brought out hot cocoa.
3. Thirty seconds later, Mai notices
Mai, assuming it was her coffee, took a sip. ── Wait. It's sweet. It's cocoa.
She freezes. The barista has already vanished into the back room. Her inner monologue starts.
4. From the next table — Professor Kant
Hearing her muttering, Professor Kant looks up from his book.
Mai: "B-but, if no one is harmed by the outcome..."
Mai shrinks back a little. "Y-yes..."
5. From another table — Professor Mill
Holding up a notebook and a calculator, Professor Mill raises his voice.
Mill starts tapping at his calculator.
Mai: "Ethics... comes out in numbers?"
6. Rising slowly — Professor Aristotle
The bearded one, who had been listening quietly, slowly stood up.
Mai: "... not 'what to do,' but 'who to become.'"
7. And then the barista comes back
Just then, the barista bursts out of the back room, flustered.
Mai:"Oh, um, yes. I noticed. But I actually like cocoa, so this is fine —"
Barista:"No no! I'll remake it! Coffee this time, for sure!"
Mai:"Um... then yes, please. Thank you."
The three philosophers looked at each other and grinned, slightly.
8. On the way out, a parting word
As Mai pays and turns to leave, Professor Aristotle calls out.
Mill asks: 'How much happiness does it produce, for whom?'
And I ask: 'What kind of person do you want to become?'
Cultivate these three questions inside yourself. They become the ground you stand on when you're in trouble."
Mai: "Three questions. I'll remember them."
Outside, the rain had stopped. Light glittered off the wet asphalt, somehow brighter than before.
Cast ↔ Schools of ethics
| Character | School | The question to carry |
|---|---|---|
| Professor Kant | Deontology | "Could this be universally permitted — by anyone, anytime?" |
| Professor Mill | Utilitarianism | "Does this increase, or decrease, the total happiness?" |
| Professor Aristotle | Virtue Ethics | "What kind of person do I want to become?" |
Next up (Vol.02): "Why do patient rights need protection?" We'll trace history to consider why society decided to designate "those who must be protected."
In closing — what ethics should each of us, as citizens, carry every day
Beyond rules, how should we behave?
Laws and corporate policies are accumulated answers to past problems. But new technology, new situations, new relationships ── there is always a space where rules don't yet exist. In those moments, how does each of us decide?
So What ── what changes because of it
Following rules alone does not build a trustworthy society. What raises the ceiling is more people who can act, in moments no one is watching, with their own internal compass. That is the only path that lifts society's upper bound.
So Why ── why it is necessary
Rules are answers handed to us from the past; nobody has written the future yet. The habit of holding questions is our only equipment for situations that don't yet have answers.
Structuring it — What / Where / Why / How
What to carry
An "attitude of judging" that integrates the three questions (universality / happiness / virtue). Not the answer itself, but the stance that produces answers.
Where to use it
Morning email, lunch choice, disagreement with a boss, an SNS post, an election vote. "Moments to think ethically" aren't far away — there are 100 of them every day.
Why it's necessary
Personal: to live a life that feels coherent to you. Organizational: to grow trust as a collective. Societal: to fill, with each person's judgment, the spaces where rules cannot keep up.
How to implement it
(1) At the moment of decision, run it through the "three questions" once. (2) Don't swallow discomfort — put it into words. (3) Translate your choice into a sentence you could explain to another person.
Ethics is not a distant philosophy — it already lives in your choices today. The only difference is whether you notice it. Just as the three philosophers debated in the cafe, each of us can carry three voices into our own decisions, every day.
Key Points ── three to take home
- Ethics is the attitude of holding questions, not memorizing rules. It is not the work of cramming answers.
- Run every daily decision through the three questions (universality, happiness, virtue) at least once. The only habit that prevents complacency and inertia.
- Train yourself to translate your judgment into a sentence you could explain to another person. A decision you can't explain is a sign that the ethical thinking is not yet deep enough.
