The teaching in one sentence
No single factor, and no combination of exactly two named factors, makes someone an ender of suffering; only knowing and seeing things as they are does, and that in turn depends on both.
A fourfold question, differently shaped
This exchange follows the same form as AN 4.173 and AN 4.174 — a question in four versions, refused four times, restated, then analyzed — but the four options here are not the logical tetralemma of existence. They are four candidate explanations: knowledge, conduct, both, or some other reason.
That difference matters for what kind of answer is possible. A question about whether something exists beyond the cessation of the six fields of contact could be dismantled as itself confused. A question about what makes someone an ender of suffering is asking for a cause, and a cause can actually be supplied — which is exactly what Sāriputta does here, where his counterparts in the two previous discourses did not.
The reductio, run four times
Sāriputta’s method is to take each of the four candidates and show that if it were sufficient on its own, an obviously wrong case would qualify.
If knowledge alone were enough, even someone who still grasps fuel — upādāya, still clinging, not yet free — could count as an ender. The same follows if conduct alone were enough, and the same again if the two together were enough, since a person can hold correct views and keep correct rules while still grasping.
The fourth candidate gets the sharpest treatment. If being an ender required some reason other than knowledge and conduct, then an ordinary, unawakened person could qualify — because an ordinary person is precisely defined by lacking both. If neither knowledge nor conduct is required, nothing rules out someone who has neither.
What actually makes the difference
Having ruled out all four candidates as sufficient on their own, Sāriputta gives a positive account built from exactly the two terms the fourth answer tried to bypass: someone lacking good conduct does not know and see things as they are. Someone accomplished in good conduct knows and sees things as they are. Knowing and seeing things as they are, one is an ender.
So the answer is not ‘neither knowledge nor conduct’ and it is not simply ‘both, added together’ either. Conduct is described as a condition for a particular kind of knowing — caraṇasampanno yathābhūtaṁ jānāti passati, one accomplished in conduct knows and sees things as they are — and it is that specific knowing, not knowledge or conduct as separate ingredients, that ends suffering.
This is a materially different structure from simple addition. Conduct is not half of the cause standing beside knowledge as the other half; conduct is what makes the relevant kind of knowledge possible in the first place, and it is the knowledge, so produced, that does the ending.
Where this echoes elsewhere in the Fours
AN 4.136 and AN 4.137, in the Puggalavagga, gave ethics, immersion, and wisdom as a strictly cumulative ladder — nobody in that scheme has wisdom without ethics beneath it. This discourse gives the same ordering a mechanism: conduct is not merely prior in a list, it is what makes the higher term possible at all.
It is also worth noting what this discourse’s vocabulary echoes. Vijjācaraṇasampanna, accomplished in knowledge and conduct, is one of the standard epithets of a Realized One, recited in full at AN 4.160’s opening. Upavāṇa’s question, stripped of its epithet form, is essentially asking Sāriputta whether that formula’s two terms operate as a checklist or as something else, and the answer says: something else.
Reading it against its neighbors
Set beside AN 4.173 and AN 4.174, this discourse shows the same refusal pattern doing different work. There, four apparently exhaustive options were all rejected because the question itself was malformed. Here, four apparently exhaustive options are rejected because each is individually insufficient, and a fifth account — not one of the four, but not their simple sum either — is supplied in its place.
A reader who has just read the two Koṭṭhita discourses might expect this one to end the same way, in an ending without positive content. It does not. The chapter is using an identical dialogue structure to show two different things a fourfold refusal can be for: dismantling a confused question, and correcting an incomplete one.
Key terms
The text
Upavāṇa’s question
§1Then Venerable Upavāṇa went up to Venerable Sāriputta, and exchanged greetings with him. When the greetings and polite conversation were over, Upavāṇa sat down to one side, and said to Sāriputta: “Reverend Sāriputta, do you become a terminator because of knowledge?”
Four refusals
§2“That’s not it, reverend.” “Do you become a terminator because of conduct?” “That’s not it, reverend.” “Do you become a terminator because of both knowledge and conduct?” “That’s not it, reverend.” “Do you become a terminator for some reason other than knowledge and conduct?” “That’s not it, reverend.”
Restating the puzzle
§3“Reverend Sāriputta, when asked whether you become a terminator because of knowledge or conduct or knowledge and conduct, or for some other reason, you say ‘that’s not it’. How then do you become a terminator?”
Sāriputta’s answer
§4“Reverend, if you became a terminator because of knowledge, then even someone who still grasps fuel could be a terminator. If you became a terminator because of conduct, then even someone who still grasps fuel could be a terminator. If you became a terminator because of both knowledge and conduct, then even someone who still grasps fuel could be a terminator. If you became a terminator for some reason other than knowledge and conduct, then even an ordinary person could be a terminator. For an ordinary person lacks knowledge and conduct. Reverend, someone lacking good conduct does not know and see things as they are. Someone accomplished in good conduct knows and sees things as they are. Knowing and seeing things as they are, one is a terminator.”
