With the dead there is no rivalry.

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

Today’s friend may be tomorrow’s foe.

An injury is much sooner forgotten than an insult.

Quarreling must lead to disorder, and disorder exhaustion.

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

Enemies to me are the sauce piquant to my dish of life.

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

Better a thousand enemies outside the house than one inside.

Enemies are so stimulating.

Opposition is not necessarily enmity; it is merely misused and made an occasion for enmity.

I shall embrace my rival—until I suffocate him.

Opposition may become sweet to a man when he has christened it persecution.
