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.

All men make mistakes.

I never found a way to tell a good man from an evil one except by what he did. It's popular now to say all men are good and evil both. But I don't believe that. Men are on one side or the other. Of course, sometimes a good man will do an evil thing. But he regrets it. And so will you, whenever you do wrong. And if you do wrong too often, regrets come so easily that you forget what wrong is. Then you've become an evil man, and you're all tied up inside, and you work and fight against others. And do you know why? Because you have no peace in your heart to satisfy you when you are alone.

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.

Any man can make mistakes, but only an idiot persists in his error

And so the good man ought to be Self-loving: because by doing what is noble he will have advantage himself and will do good to others: but the bad man ought not to be, because he will harm himself and his neighbours by following low and evil passions. In the case of the bad man, what he ought to do and what he does are at variance, but the good man does what he ought to do, because all Intellect chooses what is best for itself and the good man puts himself under the direction of Intellect.

The good man is the man who, no matter how morally unworthy he has been, is moving to become better.

To repay evil with kindness is the proof of a good man; a superior man blames himself, a common man blames others.

Todos los hombres pueden caer en un error; pero sólo los necios perseveran en él

Every man is guilty of all the good he did not do,

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it.

There is no man doth a wrong for the wrong's sake; but thereby to purchase himself profit, or pleasure, or honour, or the like. There, why should I be angry with a man for loving himself better than me? And if any man should do wrong merely out of ill nature, why, yet it is but like the thorn or briar, which prick and scratch, because they can do no other.

Through error you come to the truth! I am a man because I err! You never reach any truth without making fourteen mistakes and very likely a hundred and fourteen.

the only thing he ought to consider, if he does anything, is whether he does right or wrong, whether it is what a good man does or a bad man
