“When the two people who thus discover that they are on the same secret road are of different sexes, the friendship which arises between them will very easily pass – may pass in the first half hour – into erotic love. Indeed, unless they are physically repulsive to each other or unless one or both already loves elsewhere, it is almost certain to do so sooner or later. And conversely, erotic love may lead to Friendship between the lovers. But this, so far from obliterating the distinction between the two loves, puts it in a clearer light. If one who was first, in the deep and full sense, your Friend, is then gradually or suddenly revealed as also your lover you will certainly not want to share the Beloved’s erotic love with any third. But you will have no jealousy at all about sharing the Friendship. Nothing so enriches an erotic love as the discovery that the Beloved can deeply, truly and spontaneously enter into Friendship with the Friends you already had; to feel that not only are we two united by erotic love but we three or four or five are all travelers on the same quest, have all a common vision.”

“Do you mean to say," asked Caspian, "that you three come from a round world (round like a ball) and you've never told me! It's really too bad for you. Because we have fairy-tales in which there are round worlds and I have always loved them … Have you ever been to the parts where people walk about upside-down?"  Edmund shook his head. "And it isn't like that," he added. "There's nothing particularly exciting about a round world when you're there.”

“for the greater the love the greater the grief, and the stronger the faith the more savagely will Satan storm its fortress.”

“Even in your hobbies, has there not always been some secret attraction which the others are curiously ignorant of--something, not to be identified with, but always on the verge of breaking through, the smell of cut wood in the workshop or the clap-clap of water against the boat's side? Are not all lifelong friendships born at the moment when at last you meet another human being who has some inkling (but faint and uncertain even in the best) of that something which you were born desiring, and which, beneath the flux of other desires and in all the momentary silences between the louder passions, night and day, year by year, from childhood to old age, you are looking for, watching for, listening for? You have never had it. All the things that have ever deeply possesed your soul have been but hints of it--tantalizing glimspes, promises never quite fulfilled, echoes that died away just as they caught your ear. But if it should really become manifest--if there ever came an echo that did not die away but swelled into the sound itself--you would know it. Beyond all possibility of doubt you would say 'Here at last is the thing I was made for.' We cannot tell each other about it. It is the secret signature of each soul, the incommunicable and unappeasable want, the things we desired before we met our wives or made our friends or chose our work, and which we shall still desire on our deathbeds, when the mind no longer knows wife or friend or work. While we are, this is. If we lose this, we lose all.”

“There are only two kinds of people in the end: those who say to God, "Thy will be done," and those to whom God says, in the end, "Thy will be done." All that are in Hell, choose it. Without that self-choice there could be no Hell. No soul that seriously and constantly desires joy will ever miss it. Those who seek find. Those who knock it is opened.”

“And above all, you must be asking which door is the true one; not which pleases you best by its paint and panelling…the question should never be: ‘Do I like that kind of service?’ but ‘Are these doctrines true: Is holiness there? Does my conscience move me towards this? Is my reluctance to move to this door due to my pride, or my mere taste, or my personal dislike for this particular door-keeper?”

“And as He spoke, He no longer looked to them like a lion; but the things that began to happen after that were so great and beautiful that I cannot write them. And for us this the end of all the stories, and we can most truly say that they all lived happily ever after. But for them it was only the beginning of the real story. All their life in this world and all their adventures in Narnia had only been the cover and the title page: now at last they were beginning Chapter One of the Great Story which no one on earth has read: which goes on for ever: in which every chapter is better than the one before.”

“You all know," said the Guide, "that security is mortals' greatest enemy.”

“If they won't write the kind of books we like to read we shall have to write them ourselves.”

“You never know how much you really believe anything until its truth of falsehood becomes a matter of life and death to you. It is easy to say you believe a rope to be strong and sound as long as you are merely using it to cord a box. But suppose you had to hang by that rope over a precipice. Wouldn't you then first discover how much you really trusted it?”

“When I lay these questions before God I get no answer. But a rather special sort of 'No answer.' It is not the locked door. It is more like a silent, certainly not uncompassionate, gaze. As though He shook His head not in refusal but waiving the question. Like, 'Peace, child; you don't understand.”

“God made us: invented us as a man invents an engine. A car is made to run on petrol, and it would not run properly on anything else. Now God designed the human machine to run on Himself. He Himself is the fuel our spirits were designed to burn, or the food our spirits were designed to feed on. There is no other. That is why it is just no good asking God to make us happy in our own way without bothering about religion. God cannot give us a happiness and peace apart from Himself, because it is not there.”

“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.”

“Supposing you hear a cry for help from a man in danger. You will probably feel two desires - one a desire to give help (due to your herd instinct), the other a desire to keep out of danger (due to the instinct for self-preservation). But you will find inside you, in addition to these two impulses, a third thing which tells you that you ought to follow the impulse to help, and suppress the impulse to run away. Now this thing that judges between two instincts, that decides which should be encouraged, cannot itself be either of them. You might as well say that the sheet of music which tells you, at a given moment, to play one note on the piano and not another, is itself one of the notes on the keyboard. The Moral Law tells us the tune we have to play: our instincts are merely the keys.”

“Once when I had remarked on the affection quite often found between cat and dog, my friend replied, "Yes. But I bet no dog would ever confess it to the other dogs.”
