Man, even now, can do wonders to animals: my cat and dog live together in my house and seem to like it. It may have been one of man's functions to restore peace to the animal world, and if he had not joined the enemy he might have succeeded in doing so to an extent now hardly imaginable.
C. S. LewisThe happiness which God designs for His higher creatures is the happiness of being freely, voluntarily united to Him and to each other in an ecstasy of love and delight compared with which the most rapturous love between a man and a woman on this earth is mere milk and water. And for that they must be free.
C. S. Lewis
