κόσμον τόνδε, τὸν αὐτὸν ἁπάντων, οὔτε τις θεῶν οὐτε ἀνθρώπων ἐποίησεν, ἀλλ' ἦν ἀεὶ καὶ ἔστιν καὶ ἔσται πῦρ ἀείζωον, ἁπτόμενον μέτρα καὶ ἀποσβεννύμενον μέτρα

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "κόσμον τόνδε, τὸν αὐτὸν ἁπάντων, οὔτε τις θεῶν οὐτε ἀνθρώπων ἐποίησεν, ἀλλ' ἦν ἀεὶ καὶ ἔστιν καὶ ἔσται πῦρ ἀείζωον, ἁπτόμενον μέτρα καὶ ἀποσβεννύμενον μέτρα
• This universe, which is the same for all, has not been made by any god or man, but it always has been, is, and will be an ever-living fire, kindling itself by regular measures and going out by regular measures." in the context of "Fragment 30
• Variant translations:
The world, an entity out of everything, was created by neither gods nor men, but was, is and will be eternally living fire, regularly becoming ignited and regularly becoming extinguished.
This world . . . ever was, and is, and shall be, ever-living Fire, in measures being kindled and in measure going out.
• That which always was,
and is, and will be everlasting fire,
the same for all, the cosmos,
made neither by god nor man,
replenishes in measure
as it burns away.
 • Translated by Brooks Haxton" to mean that wisdom is timeless.
