In order to have an enemy, one must be somebody. One must be a force before he can be resisted by another force. A malicious enemy is better than a clumsy friend.

A friend is one who has the same enemies as you have.

An enemy to whom you show kindness becomes your friend, excepting lust, the indulgence of which increases its enmity.

An insincere and evil friend is more to be feared than a wild beast; a wild beast may wound your body, but an evil friend will wound your mind.

Treat your friend as if he might become an enemy.

It pays to know the enemy - not least because at some time you may have the opportunity to turn him into a friend.

It's good for everyone to understand that they are to love their enemies, simply because your enemies show you things about yourself you need to change. So in actuality enemies are friends in reverse.

It is not necessary to have enemies if you go out of your way to make friends hate you.
