Serving the Common Good as One's Own Benefit

Notes

1. §11.4.1ὠφέλημαι — Perfect first-person singular of the verb ὠφελέω (to benefit). It can be interpreted either as passive ('I have been benefited') or as middle with a reflexive sense ('I have benefited myself'). In Stoic ethics, acting for the benefit of the whole (the community) fulfills one's own rational nature, meaning that altruistic action is inherently self-beneficial.
2. §11.4.1ἵνα ἀεὶ πρόχειρον ἀπαντᾷ — A construction consisting of the conjunction ἵνα and the third-person singular subjunctive (ἀπαντᾷ). Used as an independent clause without a main governing verb (such as βλέπε or ὅρα) to express an imperative or hortatory command ('let it meet you' / 'see to it that it is...'). This is a colloquial and emphatic usage common in post-classical and Koine Greek.
3. §11.4.1μηδαμοῦ παύου — A combination of the adverb μηδαμοῦ (never, nowhere) and the second-person singular present middle imperative of παύω (παύου, cease). In this context, an infinitive meaning 'to act for the common good' (κοινωνικῶς ποιεῖν) is understood as being omitted, yielding the sense 'never cease [doing so]'.
