Sophocles, Antigone

For God hates utterly
The bray of bragging tongues.

Grief teaches the steadiest minds to waver.

How dreadful it is when the right judge judges wrong!

I have nothing but contempt for the kind of governor who is afraid, for whatever reason, to follow the course that he knows is best for the State; and as for the man who sets private friendship above the public welfare - I have no use for him either.

Nobody likes the man who brings bad news.

The ideal condition
Would be, I admit, that men should be right by instinct;
But since we are all likely to go astray,
The reasonable thing is to learn from those who can teach.

There is no happiness where there is no wisdom;
No wisdom but in submission to the gods.
Big words are always punished,
And proud men in old age learn to be wise.

Wisdom outweighs any wealth.
