Note 22 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.
Oswald J. (Oswald Joseph) Reichel translation
Diog. 137: εἶναι δὲ τὸ μὲν πῦρ τὸ θερμὸν, τὸ δ’ ὕδωρ τὸ ὑγρὸν, τόν τ’ ἀέρα τὸ ψυχρὸν καὶ τὴν γῆν τὸ ξηρόν. Plut. Sto. Rep. 43, 1, p. 1053. The air is, according to Chrysippus, φύσει ζοφερὸς and πρώτως ψυχρός. Id. De Primo Frig. 9, 1; 17, 1, p. 948, 952; Galen, Simpl. Medic. ii. 20, vol. xi. 510. Sen. Nat. Qu. iii. 10; i. 4: Aër … frigidus per se et obscurus … natura enim aëris gelida est. Conf. Cic. N. D. ii. 10, 26. Of the four properties by the pairing of which elements arise, even Aristotle had attributed one to each element as its distinguishing feature, assigning cold to water, moisture to air. ↑
