§8.15.1Μέμνησο ὅτι, ὥσπερ αἰσχρόν ἐστι ξενίζεσθαι, εἰ ἡ συκῆ σῦκα φέρει, οὕτως, εἰ ὁ κόσμος τάδε τινὰ φέρει ὧν ἐστι φορός· καὶ ἰατρῷ δὲ καὶ κυβερνήτῃ αἰσχρὸν ξενίζεσθαι, εἰ πεπύρεχεν οὗτος ἢ εἰ ἀντίπνοια γέγονεν.
Remember that, just as it is shameful to be surprised if the fig tree bears figs, so too [it is shameful to be surprised] if the universe bears these or those things of which it is productive; and for a physician and a helmsman likewise, it is shameful to be surprised if this man has a fever or if a contrary wind has blown.
