But there’s a class of persons, led astray
By false desires, and this is what they say:
“You cannot have enough: what you possess,
That makes your value, be it more or less.”
What answer would you make to such as these?
Why, let them hug their misery if they please.

[At bona pars hominum decepta cupidine falso
‘nil satis est’, inquit, ‘quia tanti quantum habeas sis’:
quid facias illi? iubeas miserum esse, libenter
quatenus id facit.]

Horace (65–8 BC) Roman poet, satirist, soldier, politician [Quintus Horatius Flaccus]

Satires [Saturae, Sermones], Book 1, # 1, “Qui fit, Maecenas,” l. 61ff (1.1.61-64) (35 BC) [tr. Conington (1874)]

But out (alas) the greater parte with sweete empoysned bate
Of welthe bewitchde, do weene their wants aboundance in eache state.
For monye maks, and mars (say they) and coyne it keepes the coyle,
It byndes the beare, it rules the roste, it putts all things to foyle.
A mann's his money, and no more, wherin confused is
An heaven of happs, a worlde of weeles, an hunnye hath of blisse.
O dottrells dome, and is it so? what guardon for these doultes
Shall we devyse? lets suffer still the foolishe frantycke foultes
To wallowe in their wilfulnes, whose under eating myndes
Is never cramde, but prooles for more and swarves not from their kyndes.
[tr. Drant (1567)]

But most of men deceiv'd by false desire,
Say, Noughts enough; 'cause they absurdly guess
At what men are, by what they do possess.
To such a Miser what is't best to do?
Let him be wretched, since he will be so.
[tr. A. B.; ed. Brome (1666)]

But most are lost in a Confounded Cheat,
They would have more, for when their Wealth is great
They think their Worth as much as their Estate:
Well then, what must we do to such a one?
Why, let him, 'tis his Will to be undone.
[tr. Creech (1684)]

Some, self-deceiv'd, who think their lust of gold
Is but a love of fame, this maxim hold,
No Fortune's large enough, since others rate
Your worth proportion'd to a large estate.
Say, for their cure what arts would you employ?
"Let them be wretched, and their choice enjoy."
[tr. Francis (1747)]

Yet thousands, duped by avarice in disguise,
Intrench themselves in maxims sage and wise.
Go on, say they, and hoard up all you can;
For wealth is worth, and money makes the man!
What shall we say to such? Since 'tis their will
Still to be wretched, let them be so still!
[tr. Howes (1845)]

But a great majority of mankind, misled by a wrong desire, cry, “No sum is enough; because you are esteemed in proportion to what you possess.” What can one do to such a tribe as this? Why, bid them be wretched, since their inclination prompts them to it.
[tr. Smart/Buckley (1853)]

But some one argues: -- many men, misled by wrong desire of fame, say no sum is enough, because we all are rated by the money we possess. What would you do with them? Why, bid them live a wretched life, since they act thus of their free will.
[tr. Millington (1870)]

But a good many people, misled by blind desire, say, "You cannot have enough: for you get your rating from what you have." What can you do to a man who talks thus? Bid him be miserable, since that is his whim.
[tr. Fairclough (Loeb) (1926)]

Mankind for the most part, fooled by its own false desires,
Says, “There’s no such thing as enough. You are worth
Only as much as you have.” And what can you do
With a person like this? Oh, well! Wish him hell and farewell,
Since he's headed that way by choice.
[tr. Palmer Bovie (1959)]

Still, since false desires fool a large portion of mankind,
they'll tell you, *Nothing's enough. What we own, we are."
What can you say? Say, "Be miserable," for that's the choice
they freely made.
[tr. Fuchs (1977)]

Too many men, bewitched by false desire, insist that
"Nothing is enough: people value you by what you own."
What can I say? Let him be miserable, that's how
He wants it!
[tr. Raffel (1983)]

And yet a good part of humankind is deceived
by false cupidity. “Nothing is enough,”
they say. “For you are esteemed for as much as you
possess.” What can you do with one of these fools?
Leave him to his misery. It’s all of his
own doing anyway.
[tr. Alexander (1999)]

But most people
want all that they desire, and so say, “There’s no such
thing as too much: you are what you acquire.”
You can always tell such a man but you
can’t tell him much. Tell him to suffer, since
that’s his choice.
[tr. Matthews (2002)]

People are enticed by a desire which continually cheats them.
"Nothing is enough," they say, "for you’re only worth what you have."
What can you do with a man like that? You might as well tell him
to be miserable, since misery is what he enjoys.
[tr. Rudd (2005 ed.)]

Still, a good many people misled by foolish desire
Say: ‘There’s never enough, you’re only what you own.’
What can one say to that? Let such people be wretched,
Since that’s what they wish.
[tr. Kline (2015)]
