A quote
Posidonius pleads the cause of our master Zeno in the only possible way; but it cannot, I hold, be pleaded even in this way. For Posidonius maintains that the word “drunken” is used in two ways,—in the one case of a man who is loaded with wine and has no control over himself; in the other, of a man who is accustomed to get drunk, and is a slave to the habit. Zeno, he says, meant the latter,—the man who is accustomed to get drunk, not the man who is drunk; and no one would entrust to this person any secret, for it might be blabbed out when the man was in his cups.
