Quarreling must lead to disorder, and disorder exhaustion.

It is very foolish to attack one’s enemy openly if one can injure him in secret.

From hell’s heart I stab at thee; for hate’s sake I spit my last breath at thee.

I shall embrace my rival—until I suffocate him.

No one wins a quarrel by quarreling.

Enemies are so stimulating.

How can we bear misfortune most easily? If we see our enemies faring worse.

The envious die not once, but as often as the envied win applause.

Perish the universe, provided I have my revenge.

He laughs best who laughs last.

We often give our enemies the means for our own destruction.

For what do we live, but to make sport for our neighbors, and laugh at them in our turn?

The men of today are born to criticize; of Achilles they see only the heel.
