“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 asked for a loving God: you have one. The great spirit you so lightly invoked, the 'lord of terrible aspect,' is present: not a senile benevolence that drowsily wishes you to be happy in your own way, not the cold philanthropy of conscientious magistrate, nor the care of a host who feels responsible for the comfort of his guests, but the consuming fire Himself, the Love that made the worlds, persistent as the artist’s love for his work and despotic as a man’s love for a dog, provident and venerable as a father’s love for a child, jealous, inexorable, exacting as love between the sexes.”

“Miracles are a retelling in small letters of the very same story which is written across the whole world in letters too large for some of us to see.”

“Excess of love, did ye say? There was no excess, there was defect. She loved her son too little, not too much. If she had loved him more there'd be no difficulty.”

“If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilised morality to savage morality.”

“I can't imagine a man really enjoying a book and reading it only once.”

“The more we believe that God hurts only to heal, the less we can believe that there is any use in begging for tenderness. A cruel man might be bribed...But suppose that what you are up against is a surgeon whose intentions are wholly good. The kinder and more conscientious he is, the more inexorably he will go on cutting. If he yielded to your entreaties, if he stopped before the operation was complete, all the pain up to that point would have been useless. But is it credible that such extremities of torture should be necessary for us? Well, take your choice. The tortures occur. If they are unnecessary, then there is no God or a bad one. If there is a good God, then these tortures are necessary. For no even moderately good Being could possibly inflict or permit them if they weren't. Either way, we're for it.”

“Logic!" said the Professor half to himself. "Why don't they teach logic at these schools? There are only three possibilities. Either your sister is telling lies, or she is mad, or she is telling the truth. You know she doesn't tell lies and it is obvious that she is not mad. For the moment then and unless any further evidence turns up, we must assume that she is telling the truth.”

“I wonder do the gods know what it feels like to be a man.”

“But very quickly they all became grave again: for, as you know, there is a kind of happiness and wonder that makes you serious. It is too good to waste on jokes.”

“Never forget that when we are dealing with any pleasure in its healthy and normal and satisfying form, we are, in a sense, on the Enemy’s (God’s) ground…He [God] made the pleasure: all our research so far has not enabled us to produce one. All we can do is to encourage the humans to take the pleasures which our Enemy [God] has produced, at at times, or in ways, or in degrees, which He [God] has forbidden. ”

“When you have reached your own room, be kind to those Who have chosen different doors and to those who are still in the hall.”

“I know,” said Peter. “Perhaps better than anyone. But you can’t stay a child forever. To choose to speak into Echo’s Well is to choose illusion. To choose to avoid the responsibilities of being an adult. The real trick—the real choice—is to keep the best of the child you were, without forgetting when you grow up. “It is the best of both worlds, Jack. Being a child is to believe in magic everywhere… “…but even Peter Pan had to grow up one day.”

“Grief ... gives life a permanently provisional feeling. It doesn't seem worth starting anything. I can't settle down. I yawn, I fidget, I smoke too much. Up till this I always had too little time. Now there is nothing but time. Almost pure time, empty successiveness.”

“I wrote this story for you, but when I began it I had not realized that girls grow quicker than books. As a result you are already too old for fairy tales, and by the time it is printed and bound you will be older still. But some day you will be old enough to start reading fairy tales again. You can then take it down from some upper shelf, dust it, and tell me what you think of it. I shall probably be too deaf to hear, and too old to understand a word you say, but I shall still be your affectionate Godfather, C. S. Lewis.”
