More quotes by C.S. Lewis, The Four Loves

"I have no duty to be anyone's Friend and no man in the world has a duty to be mine. No claims, no shadow of necessity. Friendship is unnecessary, like philosophy, like art, like the universe itself (for God did not need to create). It has no survival value; rather it is one of those things which give value to survival."
"Friendship is unnecessary, like philosophy, like art.... It has no survival value; rather it is one of those things which give value to survival."
"In God there is no hunger that needs to be filled, only plenteousness that desires to give."
"Man approaches God most nearly when he is in one sense least like God. For what can be more unlike than fullness and need, sovereignty and humility, righteousness and penitence, limitless power and a cry for help?"
"Every Christian would agree that a man's spiritual health is exactly proportional to his love for God."
