A friend is, as it were, a second self.

A good friend will always stab you in the front.

Anybody amuses me for once. A new acquaintance is like a new book. I prefer it, even if bad, to a classic.

In the end, we will remember not the words of our enemies, but the silence of our friends.

Misfortune shows those who are not really friends.

Children make your life important.

It is easier to forgive an enemy than to forgive a friend.

Let there be no purpose in friendship save the deepening of the spirit.

Walking with a friend in the dark is better than walking alone in the light.

Friendship is the only cement that will ever hold the world together.

Friendship is nothing else than an accord in all things, human and divine, conjoined with mutual goodwill and affection.

If you have a candle, the light won't glow any dimmer if I light yours off of mine.

Be slow to fall into friendship, but when you are in, continue firm and constant.

There is no friend as loyal as a book.

Friendship is always a sweet responsibility, never an opportunity

No one who can read, ever looks at a book, even unopened on a shelf, like one who cannot.

Betray a friend, and you'll often find you have ruined yourself.

Friends are nothing but a known enemy

My best friend is the man who in wishing me well wishes it for my sake.

Friendship is always a sweet responsibility, never an opportunity.

I must study politics and war that my sons may have liberty to study mathematics and philosophy.
