§4.46.1Ἀεὶ τοῦ Ἡρακλειτείου μεμνῆσθαι, ὅτι γῆς θάνατος ὕδωρ γενέσθαι καὶ ὕδατος θάνατος ἀέρα γενέσθαι καὶ ἀέρος πῦρ καὶ ἔμπαλιν.
Always remember the saying of Heraclitus, that the death of earth is to become water, and the death of water is to become air, and of air, fire, and conversely.
μεμνῆσθαι δὲ καὶ τοῦ ἐπιλανθανομένου, ᾗ ἡ ὁδὸς ἄγει· καὶ ὅτι, ᾧ μάλιστα διηνεκῶς ὁμιλοῦσι, λόγῳ τῷ τὰ ὅλα διοικοῦντι, τούτῳ διαφέρονται· καὶ οἷς καθ’ ἡμέραν ἐγκυροῦσι, ταῦτα αὐτοῖς ξένα φαίνεται· καὶ ὅτι οὐ δεῖ ὥσπερ καθεύδοντας ποιεῖν καὶ λέγειν, καὶ γὰρ καὶ τότε δοκοῦμεν ποιεῖν καὶ λέγειν· καὶ ὅτι οὐ δεῖ ὡς παῖδας τοκεώνων, τουτέστι κατὰ ψιλόν, καθότι παρειλήφαμεν.
And remember also the one who forgets whither the way leads; and that they are at variance with that which they associate with most constantly, namely, the Reason that governs the universe; and that the things they meet with daily seem strange to them; and that we must not act and speak like people asleep, for even then we seem to act and speak; and that we must not be like children of their parents, that is, merely because we have received it.
