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

Resentment kills a fool, and envy slays the simple.

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

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

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

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

I shall embrace my rival—until I suffocate him.

Enemies are so stimulating.

An injury is much sooner forgotten than an insult.

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

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

We die of comfort and by conflict live.

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