Virtue is a self-renunciation which is always arduous and painful. This virtue may be defined, the love of the laws and of our country. As this love requires a constant preference of public to private interest, it is the source of all the particular virtues; for they are nothing more than this very preference itself.
[tr. Nugent (1750)]

Virtue is a self-renunciation, which is very arduous and painful. This virtue may be defined as the love of the laws and of our country. As such love requires a constant preference of public to private interest, it is the source of all private virtues [....]
[E.g. (1904)]

Virtue is self-renunciation, which is always a very hard thing. This virtue may be defined as love of the laws and of the homeland. As this love requires a continual preference for the public interest over one’s own, it confers all the separate virtues: they are nothing more than this preference.
[tr. Stewart (2018)]

Lawfulness, puts all things into good order and makes them sound,
And often places shackles about those who are unjust.
She smooths what is rough, puts an end to excess, enfeebles arrogance;
She withers the flowers of ruin as they spring up;
She straightens crooked judgments, and overbearing acts she turns to gentleness;
She puts an end to acts of dissension,
Puts an end to the bitterness of painful strife:
Beneath her hand all things among mankind are sound and prudent.
[tr. Miller (1996)]

Good Government displays all neatness and order,
And many times she must put shackles on the breakers of laws
She levels rough places, stops Glut and Greed, takes the force from Violence:
She dries up the growing flowers of Despair as they grow;
She straightens out crooked judgments given, gentles the swollen ambitions,
And puts an end to acts of divisional strife;
She stills the gall of wearisome Hate,
And under her influence all life among mankind is harmonious and does well.
[tr. Lattimore]
