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

He laughs best who laughs last.

Resentment kills a fool, and envy slays the simple.

Quarrels would not last long if the fault was only on one side.

Many need no other provocation to enmity than that they find themselves excelled.

It would seem that in history it’s never a tooth for a tooth, but a thousand, a hundred thousand for one.

I shall embrace my rival—until I suffocate him.

We die of comfort and by conflict live.

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

With the dead there is no rivalry.

All our enemies are mortal.

It is permitted to learn even from an enemy.

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