Note 60 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.
Oswald J. (Oswald Joseph) Reichel translation
Stob. Ecl. i. 538, on the authority of Zeno; Cic. N. D. ii. 15, 40, on that of Cleanthes. Both state that the difference consists in this: Ordinary (ἄτεχνον) fire consumes things; but the πῦρ τεχνικὸν, which constitutes φύσις and ψυχὴ, preserves things. Heraclitus, too, in making primary fire the basis of things, did not mean flame, but warmth, which may be equally well described as atmospheric substance or as ψυχή. ↑
