Do not believe that you alone can be right.
The man who thinks that,
The man who maintains that only he has the power
To reason correctly, the gift to speak, the soul—
A man like that, when you know him, turns out empty.

For if any man thinks that he is alone is wise--that in speech, or in mind, he hath no peer--such a soul, when laid open, is ever found empty.

There is no greater evil than men's failure to consult and to consider.

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.

The tyrant is a child of Pride
Who drinks from his sickening cup
Recklessness and vanity,
Until from his high crest headlong
He plummets to the dust of hope.

In a just cause it is right to be confident
