§6.15.1Τὰ μὲν σπεύδει γίνεσθαι, τὰ δὲ σπεύδει γεγονέναι, καὶ τοῦ γινομένου δὲ ἤδη τι ἀπέσβη·
Some things hasten to come into being, others hasten to have passed away, and even of that which is coming into being, some part is already extinguished.
ῥύσεις καὶ ἀλλοιώσεις ἀνανεοῦσι τὸν κόσμον διηνεκῶς, ὥσπερ τὸν ἄπειρον αἰῶνα ἡ τοῦ χρόνου ἀδιάλειπτος φορὰ νέον ἀεὶ παρέχεται.
Flows and alterations continually renew the world, just as the uninterrupted passage of time always presents the infinite age as ever new.
ἐν δὴ τούτῳ τῷ ποταμῷ τί ἄν τις τούτων τῶν παραθεόντων ἐκτιμήσειεν, ἐφ’ οὗ στῆναι οὐκ ἔξεστιν;
In this river, then, which of these things that rush past could one value, on which it is not possible to stand?
ὥσπερ εἴ τίς τι τῶν παραπετομένων στρουθαρίων φιλεῖν ἄρχοιτο, τὸ δ’ ἤδη ἐξ ὀφθαλμῶν ἀπελήλυθεν.
It is just as if someone should begin to love one of the sparrows flying past, but it has already vanished from sight.
τοιοῦτον δή τι καὶ αὐτὴ ἡ ζωὴ ἑκάστου, οἷον ἡ ἀφ’ αἵματος ἀναθυμίασις καὶ ἡ ἐκ τοῦ ἀέρος ἀνάπνευσις·
Such a thing indeed is also the very life of each individual, like the vaporization from blood and the inhalation from the air.
ὁποῖον γάρ ἐστι τὸ ἅπαξ ἑλκύσαι τὸν ἀέρα καὶ ἀποδοῦναι, ὅπερ παρέκαστον ποιοῦμεν, τοιοῦτόν ἐστι καὶ τὸ τὴν πᾶσαν ἀναπνευστικὴν δύναμιν, ἣν χθὲς καὶ πρῴην ἀποτεχθεὶς ἐκτήσω, ἀποδοῦναι ἐκεῖ ὅθεν τὸ πρῶτον ἔσπασας.
For just as drawing in the air once and giving it back—which we do at every moment—is of a certain kind, so is also returning the entire breathing power, which you acquired yesterday and the day before when you were born, to that place from where you first drew it.
