Then take these things to heart, my son: for error
Is as the universal lot of man;
But whenso'er he errs, that man no longer
Is witless or unblessed, who, having fallen
Into misfortune, seeks to mend his ways
And is not obstinate: the stiffneckt temper
Must oft plead guilty to the charge of folly.
[tr. Donaldson (1848)]

Now, then, my son, take thought. A man may err;
But he is not insensate or foredoomed
To ruin, who, when he hath lapsed to evil,
Stands not inflexible, but heals the harm.
The obstinate man still earns the name of fool.
[tr. Campbell (1873)]

O ponder this, my son. To err is common
To all men, but the man who having erred
Hugs not his errors, but repents and seeks
The cure, is not a wastrel nor unwise.
No fool, the saw goes, like the obstinate fool.
[tr. Storr (1859)]

Think, therefore, on these things, my son. All men are liable to err. But when an error is made, that man is no longer unwise or unblessed who heals the evil into which he has fallen and does not remain stubborn. Self-will, we know, invites the charge of foolishness.
[tr. Jebb (1891)]

Consider this, my son! and, O remember,
To err is human; 'tis the common lot
Of frail mortality; and he alone
Is wise and happy, who, when ills are done,
Persists not, but would heal the wound he made.
[tr. Werner (1892)]

Think, then, on these things, my son. All men are liable to err; but when an error hath been made, that man is no longer witless or unblest who heals the ill into which he hath fallen, and remains not stubborn. Self-will, we know, incurs the charge of folly.
[tr. Jebb (1917)]

Mark this, my son: all men fall into sin.
But sinning, he is not forever lost
Hapless and helpless, who can make amends
And has not set his face against repentance.
Only a fool is governed by self-will.
[tr. Watling (1939)]

Think of these things, my son. All men may err
but error once committed, he's no fool
nor yet unfortunate, who gives up his stiffness
ad cures the trouble he has fallen in.
Stubbornness and stupidity are twins.
[tr. Wyckoff (1954)]

Be warned, my son, No man alive is free
From error, but the wise and prudent man
When he has fallen into evil courses
Does not persist, but tries to find amendment ....
[tr. Kitto (1962)]

Take these things to heart, my son, I warn you.
All men make mistakes, it is only human.
But once the wrong is done, a man
can turn his back on folly, misfortune too,
if he tries to make amends, however low he's fallen,
and stops his bullnecked ways. Stubbornness
brands you for stupidity -- pride is a crime
[tr. Fagles (1982), l. 1131ff]

Therefore, think about this, child. For men,
all of them, it is common to make mistakes.
Whenever he does make a mistake, that man is still not
foolish or unhappy who, fallen into evil,
applies a remedy and does not become immovable.
Stubborn self-will incurs a charge of stupidity.
[tr. Tyrell/Bennett (2002)]

Understand this: All men make mistakes. But when they do, it would be a wise and well acting man who corrected that mistake and moved on rather than stayed there stubbornly and unrepentant. The stubborn man is rewarded with more errors.
[tr. Theodoridis (2004)]

Consider this, my son.
All men make mistakes -- that's not uncommon.
But when they do, they’re no longer foolish
or subject to bad luck if they try to fix
the evil into which they’ve fallen,
once they give up their intransigence.
Men who put their stubbornness on show
invite accusations of stupidity.
[tr. Johnston (2005), l. 1138ff]

Therefore, think on these things, my child; for every human being makes mistakes, but when he has made a mistake, that man is no longer foolish and unhappy who remedies the evil into which he has fallen and is not stubborn. Obstinacy brings the charge of stupidity.
[tr. Thomas (2005)]
