Note 109 — Chapter I · SPECULATIVE PHILOSOPHY IN GREECE, BEFORE AND IN THE TIME OF SOKRATES.
Reading edition
Empedokles, Frag. v. 77-83, ed. Karsten, p. 96:
φύσις οὐδενός ἐστιν ἁπάντων θνητῶν, οὐδέ τις οὐλομένου θανατοῖο τελευτὴ, ἀλλὰ μόνον μίξις τε διάλλαξίς τε μιγέντων ἐστι, φύσις δ’ ἐπὶ τοῖς ὀνομάζεται ἀνθρώποισιν....
Φύσις here is remarkable, in its primary sense, as derivative from φύομαι, equivalent to γένεσις. Compare Plutarch adv. Koloten, p. 1111, 1112.
