The teaching in one sentence
Character can be known, but only under conditions that rule out quick impressions, casual contact, and unreflective judges.
Four things, one fixed set of conditions
Ethics is known by living with someone. Purity is known by dealing with them. Resilience is known in times of trouble. Wisdom is known through discussion. Each of the first and last is given the identical qualifying formula: only after a long time, not casually; only when attentive, not when inattentive; and only by the wise, not the witless.
That the formula is stated in full for the first and last item, and implied by ellipsis for the middle two, is the discourse’s own way of saying it governs all four equally. Nothing about ethics being knowable requires a longer test than wisdom does, and nothing about wisdom is exempt from needing an attentive, wise observer any more than ethics is.
Ethics and purity: consistency over time
Ethics is known by watching whether a person’s deeds, over a long time, are intact, impeccable, spotless, and unmarred and their behavior consistent, against the alternative of deeds broken, tainted, spotty, and marred with inconsistent behavior.
Purity works the same test on a different axis: whether someone deals with everyone — one person, two, three, many — the same way, or shifts their conduct from one dealing to the next. In both cases the discovery is not a single act observed once but a pattern only visible across repetition.
Resilience: the eight worldly conditions
The third case turns on how someone meets the loss of family, wealth, or health. One person, on losing these, sorrows, wails, laments, and falls into confusion. Another reflects: worldly life is like that. Incarnation is like that. That’s why the eight worldly conditions revolve around the world, and the world revolves around them: gain and loss, fame and disgrace, blame and praise, pleasure and pain.
Loka-dhamma, the eight worldly conditions, is a standard set naming the four pairs of reversals that come to everyone regardless of conduct — gain paired with loss, fame with disgrace, blame with praise, pleasure with pain. The reflection offered here is not a denial that loss hurts; it is a placing of the particular loss inside a pattern that applies to everyone alive, which is exactly the kind of reflection that only shows itself when trouble actually arrives. There is no way to test for this resilience except by trouble occurring.
Wisdom: the fish that gives itself away
The fourth case alone gets a simile, and a vivid one. A witless person in discussion cannot bring up a deep and meaningful saying that is peaceful, sublime, beyond the scope of logic, subtle, comprehensible to the astute, and cannot explain meaning briefly or in detail when speaking on the teaching. A wise person can, on every count.
The comparison: a person with clear eyes standing on a lake’s bank sees a fish rise, and from nothing more than its approach, its ripples, and its force, knows immediately whether it is a big fish or a little one. An observer with the right training reads a discussion’s few visible signs and draws an equally immediate conclusion about the mind behind it.
It is worth noticing what this simile does and does not claim. The judgment is fast — a fish’s rise is a moment, not a season — which sits in some tension with the ‘long time’ requirement stated for all four items. The resolution is in who is doing the looking: speed is available only to a clear-eyed, already-skilled observer, and the long-time requirement is what produces that skill in the first place. A witless observer gets no shortcut from the simile at all.
What the conditions are actually ruling out
Read together, the four items and their shared conditions amount to a sustained warning against exactly the kind of judgment that is easiest to make and hardest to trust: a first impression, formed casually, by someone not paying close attention, who may not have the discernment to interpret what they are seeing even if they were.
The discourse does not say character is unknowable. It says the ordinary way people actually form opinions about each other — quickly, in passing, without much reflection — is precisely the method guaranteed not to work for any of the four things named here.
Key terms
The text
Four things, four conditions
§1“Mendicants, these four things can be known in four situations. What four? You can get to know a person’s ethics by living with them. But only after a long time, not casually; only when attentive, not when inattentive; and only by the wise, not the witless. You can get to know a person’s purity by dealing with them. … You can get to know a person’s resilience in times of trouble. … You can get to know a person’s wisdom by discussion. But only after a long time, not casually; only when attentive, not when inattentive; and only by the wise, not the witless.
Ethics, known by living together
§2‘You can get to know a person’s ethics by living with them. But only after a long time, not casually; only when attentive, not when inattentive; and only by the wise, not the witless.’ That’s what I said, but why did I say it? Take an individual who’s living with someone else. They come to know: ‘For a long time this venerable’s deeds have been broken, tainted, spotty, and marred. Their deeds and behavior are inconsistent. This venerable is unethical, not ethical.’ Take another individual who’s living with someone else. They come to know: ‘For a long time this venerable’s deeds have been intact, impeccable, spotless, and unmarred. Their deeds and behavior are consistent. This venerable is ethical, not unethical.’ That’s why I said that you can get to know a person’s ethics by living with them. But only after a long time, not a short time; only when attentive, not when inattentive; and only by the wise, not the witless.
Purity, known by dealing
§3‘You can get to know a person’s purity by dealing with them. …’ That’s what I said, but why did I say it? Take an individual who has dealings with someone else. They come to know: ‘This venerable deals with one person in one way. Then they deal with two, three, or many people each in different ways. They’re not consistent from one deal to the next. This venerable’s dealings are impure, not pure.’ Take another individual who has dealings with someone else. They come to know: ‘This venerable deals with one person in one way. Then they deal with two, three, or many people each in the same way. They’re consistent from one deal to the next. This venerable’s dealings are pure, not impure.’ That’s why I said that you can get to know a person’s purity by dealing with them. …
Resilience, known in trouble
§4‘You can get to know a person’s resilience in times of trouble. …’ That’s what I said, but why did I say it? Take someone who experiences loss of family, wealth, or health. But they don’t reflect: ‘Worldly life is like that. Incarnation is like that. That’s why the eight worldly conditions revolve around the world, and the world revolves around the eight worldly conditions: gain and loss, fame and disgrace, blame and praise, pleasure and pain.’ They sorrow and wail and lament, beating their breast and falling into confusion.

Wisdom, known by discussion
§5‘You can get to know a person’s wisdom by discussion. But only after a long time, not casually; only when attentive, not when inattentive; and only by the wise, not the witless.’ That’s what I said, but why did I say it? Take an individual who is discussing with someone else. They come to know: ‘Judging by this venerable’s approach, by what they’re getting at, and by how they discuss a question, they’re witless, not wise. Why is that? This venerable does not bring up a deep and meaningful saying that is peaceful, sublime, beyond the scope of logic, subtle, comprehensible to the astute. When this venerable speaks on Dhamma they’re not able to explain the meaning, either briefly or in detail. They can’t teach it, assert it, establish it, clarify it, analyze it, or reveal it. This venerable is witless, not wise.’ Suppose a person with clear eyes was standing on the bank of a lake. They’d see a little fish rising, and think: ‘Judging by this fish’s approach, by the ripples it makes, and by its force, it’s a little fish, not a big one.’ In the same way, an individual who is discussing with someone else would come to know: ‘Judging by this venerable’s approach, by what they’re getting at, and by how they discuss a question, they’re witless, not wise. …’ Take another individual who is discussing with someone else. They come to know: ‘Judging by this venerable’s approach, by what they’re getting at, and by how they discuss a question, they’re wise, not witless. Why is that? This venerable brings up a deep and meaningful saying that is peaceful, sublime, beyond the scope of logic, subtle, comprehensible to the astute. When this venerable speaks on Dhamma they’re able to explain the meaning, either briefly or in detail. They teach it, assert it, establish it, clarify it, analyze it, and reveal it. This venerable is wise, not witless.’ Suppose a man with clear eyes was standing on the bank of a lake. He’d see a big fish rising, and think: ‘Judging by this fish’s approach, by the ripples it makes, and by its force, it’s a big fish, not a little one.’ In the same way, an individual who is discussing with someone else would come to know: ‘Judging by this venerable’s approach, by what they’re getting at, and by how they articulate a question, they’re wise, not witless. …’ That’s why I said that you can get to know a person’s wisdom by discussion. But only after a long time, not casually; only when attentive, not when inattentive; and only by the wise, not the witless. These are the four things that can be known in four situations.”
