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

Revenge may be wicked, but it’s natural.

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

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

All our enemies are mortal.

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

Today’s friend may be tomorrow’s foe.

He laughs best who laughs last.

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

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

Rivalry is the whetstone of talent.

Hoping for new friendship from old enemies is / Like expecting to find a rose in a furnace.

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