Writer and scholar C.S. Lewis taught at Oxford University and became a renowned Christian apologist writer, using logic and philosophy to support the tenets of his faith. He is also known throughout the world as the author of The Chronicles of Narnia fantasy series, which have been adapted into various films for the big and small screens.

“To love at all is to be vulnerable. Love anything and your heart will be wrung and possibly broken. If you want to make sure of keeping it intact you must give it to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements. Lock it up safe in the casket or coffin of your selfishness. But in that casket, safe, dark, motionless, airless, it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable.”

― C.S. Lewis, The Four Loves
