Be courteous to all, but intimate with few, and let those few be well tried before you give them your confidence.

The sincere friends of this world are as ship lights in the stormiest of nights.

It is more shameful to distrust our friends than to be deceived by them.

It is important to our friends to believe that we are unreservedly frank with them, and important to friendship that we are not.

Friendship, like the immortality of the soul, is too good to be believed.

Our friends interpret the world and ourselves to us, if we take them tenderly and truly.

The most I can do for my friend is simply be his friend.

Am I not destroying my enemies when I make friends of them?

Friendship needs no words - it is solitude delivered from the anguish of loneliness.

There is nothing on this earth more to be prized than true friendship.
