“God created things which had free will. That means creatures which can go wrong or right. Some people think they can imagine a creature which was free but had no possibility of going wrong, but I can't. If a thing is free to be good it's also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having. A world of automata -of creatures that worked like machines- would hardly be worth creating. The 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've got to be free. Of course God knew what would happen if they used their freedom the wrong way: apparently, He thought it worth the risk. (...) If God thinks this state of war in the universe a price worth paying for free will -that is, for making a real world in which creatures can do real good or harm and something of real importance can happen, instead of a toy world which only moves when He pulls the strings- then we may take it it is worth paying.”

“You will say that these are very small sins; and doubtless, like all young tempters, you are anxious to be able to report spectacular wickedness. But do remember, the only thing that matters is the extent to which you separate the man from the Enemy. It does not matter how small the sins are provided that their cumulative effect is to edge the man away from the Light and out into the Nothing. Murder is no better than cards if cards can do the trick. Indeed the safest road to Hell is the gradual one-the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts.”

“Praise is the mode of love which always has some element of joy in it.”

“To be a Christian means to forgive the inexcusable because God has forgiven the inexcusable in you.”

“Courage is not simply one of the virtues but the form of every virtue at the testing point, which means at the point of highest reality. ”

“Are the gods not just?" "Oh no, child. What would become of us if they were?”

“Here. All of you. And you, doorkeeper. No one is to be let out of the house today. And anyone I catch talking about this young lady will be first beaten to death and then burned alive and after that be kept on bread and water for six weeks. There.”

“This wasn't a garden,' said Susan presently. 'It was a castle...”

“Perhaps the experience had been so complete that repetition would be vulgarity - like asking to hear the same symphony twice in a day.” 

“Puddleglum's my name. But it doesn't matter if you forget it. I can always tell you again.”
