37.1 ἐὰν ὑπὲρ δύναμιν ἀναλάβῃς τι πρόσωπον, καὶ ἐν τούτῳ ἠσχημόνησας καί ὃ ἠδύνασο ἐκπληρῶσαι παρέλιπες.
Don't Exceed Your Capabilities
πρόσωπον: “social role.” The word basically means “face,” but is extended to refer to a mask, a theatrical or literary character, a physical person or individual, and a persona or role that one can fill (ἐκπληρῶσαι) well or poorly. According to the fullest Stoic accounts, we have four personae according to 1) our nature as human beings; 2) our individual natures; 3) the circumstances imposed on us by chance and time (e.g., into what city we were born); and 4) the choices we make based on the kind of life we want to lead (Smith 2014).
