In a just cause it is right to be confident

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.

The man the state has put in place must have obedient hearing to his least command when it is right, and even when it's not

How dreadful it is when the right judge judges wrong

Much wisdom often goes with fewest words.

Ignorant men don't know what good they hold in their hands until they've flung it away.
