True friendship is like sound health, the value of it is seldom known until it is lost.
- C. C. Colton
Sympathy constitutes friendship but in love there is a sort of antipathy, or opposing passion. Each strives to be the other, and both together make up one whole.
- Samuel Taylor Coleridge
It is not a lack of love, but a lack of friendship that makes unhappy marriages.
- Friedrich Wilhelm Nietzsche
Do you know what friendship is... it is to be brother and sister; two souls which touch without mingling, two fingers on one hand.
- Victor Hugo, The Hunchback of Notre Dame, Chapter 13
At the shrine of friendship never say die, let the wine of friendship never run dry. Les Miserables
- Victor Hugo
The glory of friendship is not the outstretched hand, nor the kindly smile, nor the joy of companionship it is the spiritual inspiration that comes to one when you discover that someone else believes in you and is willing to trust you with a friendship.
- Ralph Waldo Emerson
To be capable of steady friendship or lasting love, are the two greatest proofs, not only of goodness of heart, but of strength of mind.
- William Hazlitt
The holy passion of Friendship is of so sweet and steady and loyal and enduring a nature that it will last through a whole lifetime, if not asked to lend money.
- Mark Twain
