A Cosmologist

Lokāyatikasutta

Sāvatthī
Speakers
The Buddha and a brahmin cosmologist (lokāyatika)
Form
Four questions in sequence, each answer named a distinct cosmology, followed by the middle way and a closing conversion

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

Why this discourse

A brahmin identified as a lokāyatika — a term associated with a tradition of speculative natural philosophy, later linked to positions read as materialist, though this reading guide doesn't claim a precise identification with any later school — puts to the Buddha not two positions but four: everything exists, everything doesn't exist, everything is one, and everything is many. Each is named in turn as one of four cosmologies — the oldest, the second, the third, the fourth — without argument, before the Buddha responds with the same middle-way formula used elsewhere in this saṃyutta for narrower pairs of extremes. The discourse leaves an honest puzzle unresolved: the closing formula names avoiding "these two extremes," yet four positions have just been listed, and the text itself doesn't clarify whether the middle way is meant to set aside all four or specifically the first pair.

Reading guide

Four positions where other discourses give two

Every other brahmin-question discourse in this chapter poses a single pair of extremes; this one uniquely poses four distinct cosmological positions in succession, each treated as its own numbered claim rather than folded into a binary.

Named without argument, oldest to newest

Each position is introduced only to be labeled — "this is the oldest cosmology," "this is the second cosmology," and so on — with no reasoning given for why each one might seem plausible, unlike the brahmin's engagement in some other discourses in this collection.

An honest interpretive puzzle left open

The closing formula speaks of avoiding "these two extremes," but four positions have been named; this reading guide doesn't resolve whether the middle way is meant to address all four together or specifically returns to the first pair, since the source text itself doesn't clarify the point.

The same middle way, regardless of how many extremes precede it

Whatever the resolution of that puzzle, the content of the Buddha's answer doesn't change: the same twelve-link chain, run forward to suffering's arising and in reverse to its cessation, already given for the questions in SN 12.15, SN 12.46, and SN 12.47.

A term worth handling with care

Lokāyata is sometimes rendered "cosmology" and sometimes associated with later materialist or skeptical philosophy, but its precise scope in this discourse's own context is genuinely debated among scholars, and this reading guide doesn't assert a firm identification beyond what the text itself states.

Key terms

lokāyatiko brāhmaṇo — “a brahmin cosmologist” — lokāyatika, a term whose precise scope and later associations with materialist philosophy are genuinely debated.
sabbamatthi… jeṭṭhametaṁ lokāyataṁ — “all exists: this is the oldest cosmology” — the first of four positions named in turn.
sabbamekattaṁ… tatiyametaṁ lokāyataṁ — “all is oneness: this is the third cosmology” — a position not raised by the other brahmins questioning existence elsewhere in this saṃyutta.
sabbaṁ puthuttaṁ… catutthametaṁ lokāyataṁ — “all is diversity: this is the fourth cosmology” — the fourth and final position named.
ubho ante anupagamma majjhena tathāgato dhammaṁ deseti — “avoiding these two extremes, the Realized One teaches by the middle way” — the same recurring formula, here following four named positions rather than two.

The text

The discourse in full. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1At Sāvatthī. Then a brahmin cosmologist went up to the Buddha … Seated to one side he said to the Buddha:

§2“Worthy Gotama, does all exist?” “‘All exists’: this is the oldest cosmology, brahmin.”

§3“Then does all not exist?” “‘All does not exist’: this is the second cosmology.

§4“Well, is all oneness?” “‘All is oneness’: this is the third cosmology.

§5“Then is all expansiveness?” “‘All is expansiveness’: this is the fourth cosmology.

§6Avoiding these two extremes, the Realized One teaches by the middle way: ‘Ignorance is a requirement for choices. Choices are a requirement for consciousness. … That is how this entire mass of suffering originates. When ignorance fades away and ceases with nothing left over, choices cease. When choices cease, consciousness ceases. … That is how this entire mass of suffering ceases.’”

§7When he said this, the brahmin cosmologist said to the Buddha, “Excellent, worthy Gotama! Excellent! … From this day forth, may the worthy Gotama remember me as a lay follower who has gone for refuge for life.”
