False greatness is unsociable and inaccessible; as it is sensible of its weakness, it conceals itself, or at least does not show itself openly, and only allows just so much to be seen as will carry on the deceit, so as not to appear what it really is, namely, undoubtedly mean. True greatness, on the contrary, is free, gentle, familiar, and popular; it allows itself to be touched and handled, loses nothing by being seen closely, and is the more admired the better it is known.
 
[La fausse grandeur est farouche et inaccessible: comme elle sent son faible, elle se cache, ou du moins ne se montre pas de front, et ne se fait voir qu’autant qu’il faut pour imposer et ne paraître point ce qu’elle est, je veux dire une vraie petitesse. La véritable grandeur est libre, douce, familière, populaire; elle se laisse toucher et manier, elle ne perd rien à être vue de près; plus on la connaît, plus on l’admire.]

False Greatness is unsociable, inaccessible, as if 'twere sensible of its weakness, and strove to conceal it. 'Twill not be seen, except just so much, as may carry on the Deceit, but dares not shew its Face for fear of being discover'd: Discover'd how really little and mean it is. True Greatness, on the contrary, is free, complaisant, familiar, popular, suffers it self to be touch'd and handl'd, loses nothing by being view'd near at hand, is rather more known and admir'd for it.
[Bullord ed. (1696)]

False greatness is unsociable and remote: conscious of its own frailty, it hides, or at least averts its face, and reveals itself only enough to create an illusion and not be recognized as the meanness that it really is. True greatness is free, kind, familiar and popular; it lets itself be touched and handled, it loses nothing by being seen at close quarters; the better one knows it, the more one admires it.
