Diogenes Laertius, Zeno 7.1. 118-119
“Serious people are truly dedicated and on guard to make themselves better by preparing both to keep corrupting things away from them and trying to ensure that good things are near at hand. But they are also unaffected: they have peeled away adornments from their voice and their face.
They also have no concern for business since they abstain from doing anything which transgresses their duty. They do drink, but they do not get drunk. Indeed, they will also not go mad—even though the sometimes the same fantasies will still occur to them because of depression or delirium, but because of the logic of what they have selected but against nature.
And a wise person will never grieve because they understand that grief is an illogical closure of the soul, as Apollodorus says in his Ethics. These people are also godlike because they have some divine aspect in them; the scoundrel is godless.”
Ἀκιβδήλους τοὺς σπουδαίους φυλακτικούς τ᾿ εἶναι τοῦ ἐπὶ τὸ βέλτιον αὑτοὺς παριστάναι, διὰ παρασκευῆς τῆς τὰ φαῦλα μὲν ἀποκρυπτούσης, τὰ δ᾿ ὑπάρχοντα ἀγαθὰ φαίνεσθαι ποιούσης. ἀπλάστους τε· περιῃρηκέναι γὰρ ἐν τῇ φωνῇ τὸ πλάσμα καὶ τῷ εἴδει. ἀπράγμονάς τ᾿ εἶναι· ἐκκλίνειν γὰρ τὸ πράττειν τι παρὰ τὸ καθῆκον. καὶ οἰνωθήσεσθαι μέν, οὐ μεθυσθήσεσθαι δέ. ἔτι δ᾿ οὐδὲ μανήσεσθαι· προσπεσεῖσθαι μέντοι ποτὲ αὐτῷ φαντασίας ἀλλοκότους διὰ μελαγχολίαν ἢ λήρησιν, οὐ κατὰ τὸν τῶν αἱρετῶν λόγον, ἀλλὰ παρὰ φύσιν. οὐδὲ μὴν λυπηθήσεσθαι τὸν σοφόν, διὰ τὸ τὴν λύπην ἄλογον εἶναι συστολὴν τῆς ψυχῆς, ὡς Ἀπολλόδωρός φησιν ἐν τῇ Ἠθικῇ.
Θείους τ᾿ εἶναι· ἔχειν γὰρ ἐν ἑαυτοῖς οἱονεὶ θεόν. τὸν δ᾿ φαῦλον ἄθεον.
“It is not possible to think when you’re drunk. For drunkenness is extremely prone to error and people are really talkative over wine…”
Οὐχ οἷον δὲ μεθυσθήσεσθαι τὸν νοῦν ἔχοντα· τὴν γὰρ μέθην ἁμαρτητικὸν περιέχειν, λήρησιν εἶναι <γὰρ> παρὰ τὸν οἶνον,
