Note 29 — Chapter XXIII · PROTAGORAS.
Reading edition
Plato, Protag. pp. 321-322. ἀπορίᾳ οὖν ἐχόμενος ὁ Προμηθεὺς ἥντινα σωτηρίαν τῷ ἀνθρώπῳ εὕροι, κλέπτει Ἡφαίστου καὶ Ἀθηνᾶς τὴν ἕντεχνον σοφίαν σὺν πυρί.… Τὴν μὲν οὖν περὶ τὸν βίον σοφίαν ἄνθρωπος ταύτῃ ἔσχε, τὴν δὲ πολιτικὴν οὐκ εἶχεν· ἦν γὰρ παρὰ τῷ Δίϊ, &c.
If the reader will compare this with the doctrine delivered in the Platonic Timæus — that the inferior animals spring from degenerate men — he will perceive the entire variance between the two (Timæus, pp. 91-92).
