§8.12.1Ὅταν ἐξ ὕπνου δυσχερῶς ἐγείρῃ, ἀναμιμνῄσκου ὅτι κατὰ τὴν κατασκευήν σου ἐστὶ καὶ κατὰ τὴν ἀνθρωπικὴν φύσιν τὸ πράξεις κοινωνικὰς ἀποδιδόναι, τὸ δὲ καθεύδειν κοινὸν καὶ τῶν ἀλόγων ζῴων· ὃ δὲ κατὰ φύσιν ἑκάστῳ, τοῦτο οἰκειότερον καὶ προσφυέστερον καὶ δὴ καὶ προσηνέστερον.
When you are reluctant to rise from sleep, remind yourself that to perform social actions is in accordance with your own constitution and with human nature, whereas sleeping is common also to irrational animals; and what is in accordance with nature for each is more truly his own, more fitting, and indeed more agreeable.
