It looks like we have a significant difference among sources as to how PD14 should end, so we need to have a discussion as to why that is the case, and this thread is the best place for that. This is prompted by Nate's graphic here Principal Doctrine 14 which cites Inwood and Gerson:
XIV "The purest security is that which comes from a quiet life and withdrawal from the many, although a certain degree of security from other men does come by means of the power to repel [attacks] and by means of prosperity." (Epicurus, Principal Doctrine 14) PD14 Translated by Inwood and Gerson (1994)
The other cites we've listed initially are:
Bailey Version: 14. The most unalloyed source of protection from men, which is secured to some extent by a certain force of expulsion, is in fact the immunity which results from a quiet life, and retirement from the world.
Greek: 14Τῆς ἀσφαλείας τῆς ἐξ ἀνθρώπων γενομένης μέχρι τινὸς δυνάμει τινὶ ἐξερειστικῇ καὶ εὐπορίᾳ εἰλικρινεστάτη γίνεται ἡ ἐκ τῆς ἡσυχίας καὶ ἐκχωρήσεως τῶν πολλῶν ἀσφάλεια.
Hicks translation: 14 When tolerable security against our fellow-men is attained, then on a basis of power arises most genuine bliss, to wit, the security of a private life withdrawn from the multitude.
Saint-Andre translation: 14 Although some measure of safety from others comes from the power to fight them off and from abundant wealth, the purest security comes from solitude and breaking away from the herd.
Emidio Spinnelli paper: The purest security is that which comes from a quiet life and withdrawal from the many, after having obtained a certain degree of security with respect to other men by means of comfort and prosperity.
