The Buddha alone, addressing the assembled mendicants
Form
Four compact three-item chains, each fixed at unconscientious and witless with one middle quality cycling through
Length
~2 minutes to read
Northern parallel
A rough counterpart may exist in the Chinese Saṃyukta-āgama (T99), though this reading guide does not assert a specific matching sutra number
Difficulty
★★★★☆ — best read as a direct continuation of SN 14.18's combinatorial pattern
Why this discourse
SN 14.18 fixed faithless and witless as bookends and cycled five different middle qualities between them. This discourse moves the fixed opening term one step along the septet, to unconscientious, and cycles through only four middles — imprudent, unlearned, lazy, and unmindful — because the fifth possible middle, faithless, already appeared paired with unconscientious in SN 14.18's very first chain. Nothing here needs to repeat that specific combination, so the count shrinks from five chains to four, continuing what turns out to be a systematic, exhaustive count through every possible pairing of this septet's middle terms.
Reading guide
One step along the septet, one fewer chain
Where SN 14.18 fixed faithless first, this discourse fixes unconscientious first — the second item in SN 14.17's original order — and needs one fewer middle term because the faithless-unconscientious pair is already accounted for.
Four chains, each compressed into very little space
Unlike SN 14.18's first two chains, spelled out at length, every chain in this discourse fits into a single dense segment, the negative and positive halves run together with minimal elision markers.
A pattern becoming visible across discourses
Read alongside SN 14.18's five chains, this discourse's four suggest a shrinking count discourse by discourse — a pattern this reading guide will confirm directly once SN 14.22's closing verse is reached.
The same fixed final term throughout
Witless still closes every chain here, exactly as in SN 14.18; only the opening term and the available middles have shifted.
No new vocabulary, only new combinations
As with SN 14.18, every quality named in this discourse already appeared in SN 14.17's original septet; the content here is entirely a matter of which pairs get combined.

Question 1 of 10
What term does this discourse fix as every chain's opening, unlike SN 14.18?
Correct: A. One step along SN 14.17's original sequence from SN 14.18's faithless.
Question 2 of 10
How many chains does this discourse build, compared to SN 14.18's five?
Correct: A. One fewer, since the faithless-unconscientious pairing was already covered.
Question 3 of 10
Why doesn't this discourse include a chain pairing unconscientious with faithless?
Correct: A. Avoiding repetition of a combination already given.
Question 4 of 10
What term closes every chain in this discourse, matching SN 14.18?
Correct: A. The same fixed final term carried over from SN 14.18.
Question 5 of 10
Is any new quality introduced in this discourse, beyond SN 14.17's original septet?
Correct: A. A recombination exercise, not an expansion of vocabulary.
Question 6 of 10
What middle term does this discourse's first chain use?
Correct: A. Unconscientious, imprudent, witless — the first of four chains.
Question 7 of 10
How compact is each chain's presentation compared to SN 14.18's first two chains?
Correct: A. Minimal elision markers packing negative and positive halves together.
Question 8 of 10
