Enemies are so stimulating.

When a coward sees a man he can beat, he becomes hungry for a fight.

With the dead there is no rivalry.

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

An injury is much sooner forgotten than an insult.

We die of comfort and by conflict live.

I tell you, there is such a thing as creative hate!

It is permitted to learn even from an enemy.

Hate must make a man productive. Otherwise one might as well love.

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

Do we want laurels for ourselves most, / Or most that no one else shall have any?

No one wins a quarrel by quarreling.

Envy and hatred are apt to blind the eyes and render them unable to behold things as they are.
