“And he writhed inside at what seemed the cruelty and unfairness of the demand. He had not yet learned that if you do one good deed your reward usually is to do another and harder and better one.”

“...Aslan didn't tell Pole what would happen. He only told her what to do. That fellow will be the death of us once he's up, I shouldn't wonder. But that doesn't let us off following the signs.”

“But, first, remember, remember, remember the signs. Say them to yourself when you wake in the morning and when you lie down at night, and when you wake in the middle of the night. And whatever strange things may happen to you, let nothing turn your mind from following the signs. And secondly, I give you a warning. Here on the mountain I have spoken to you clearly: I will not often do so down in Narnia. Here on the mountain, the air is clear and your mind is clear; as you drop down into Narnia, the air will thicken. Take great care that it does not confuse your mind. And the signs which you have learned here will not look at all as you expect them to look, when you meet them there. That is why it is so important to know them by heart and pay no attention to appearances. Remember the signs and believe the signs. Nothing else matters.”

“By starving the sensibility of our pupils we only make them easier prey to the propagandist when he comes. For famished nature will be avenged and a hard heart is no infallible protection against a soft head.”

“For pride is spiritual cancer: it eats up the very possibility of love, or contentment, or even common sense.”

“I daren't come and drink," said Jill.  Then you will die of thirst," said the Lion. Oh dear!" said Jill, coming another step nearer."I suppose I must go and look for another stream then." There is no other stream," said the Lion.”

“You can’t go on “seeing through” things forever. The whole point of seeing through something is to see something through it. To “see through” all things is the same as not to see.”

“Spiteful words can hurt your feelings but silence breaks your heart.”

“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.”

“The bolt of Tash falls from above!' 'Does it ever get caught on a hook halfway?”

“Walking and talking are two very great pleasures, but it is a mistake to combine them. Our own noise blots out the sounds and silences of the outdoor world; and talking leads almost inevitably to smoking, and then farewell to nature as far as one of our senses is concerned. The only friend to walk with is one who so exactly shares your taste for each mood of the countryside that a glance, a halt, or at most a nudge, is enough to assure us that the pleasure is shared.”

“I do not think there is a demonstrative proof (like Euclid) of Christianity, nor of the existence of matter, nor of the good will and honesty of my best and oldest friends. I think all three are (except perhaps the second) far more probable than the alternatives. The case for Christianity in general is well given by Chesterton…As to why God doesn't make it demonstratively clear; are we sure that He is even interested in the kind of Theism which would be a compelled logical assent to a conclusive argument? Are we interested in it in personal matters? I demand from my friend trust in my good faith which is certain without demonstrative proof. It wouldn't be confidence at all if he waited for rigorous proof. Hang it all, the very fairy-tales embody the truth. Othello believed in Desdemona's innocence when it was proved: but that was too late. Lear believed in Cordelia's love when it was proved: but that was too late. 'His praise is lost who stays till all commend.' The magnanimity, the generosity which will trust on a reasonable probability, is required of us. But supposing one believed and was wrong after all? Why, then you would have paid the universe a compliment it doesn't deserve. Your error would even so be more interesting and important than the reality. And yet how could that be? How could an idiotic universe have produced creatures whose mere dreams are so much stronger, better, subtler than itself?”

“One of the drawbacks about adventures is that when you come to the most beautiful places you are often too anxious and hurried to appreciate them.”

“Further up and further in” 

“If you want to get warm you must stand near the fire: if you want to be wet you must get into the water. If you want joy, power, peace, eternal life, you must get close to, or even into, the thing that has them.”
