“Three hundred years ago people in England were putting witches to death. Was that what you call the 'Rule of Human Nature or Right Conduct?’ But surely the reason we do not execute witches is that we do not believe there are such things. If we did—if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather—surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did? There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.”

“Our struggle is--isn't it?--to achieve and retain faith on a lower level. To believe that there is a Listener at all. For as the situation grows more and more desperate, the grisly fears intrude. Are we only talking to ourselves in an empty universe? The silence is often so emphatic. And we have prayed so much already”

“Don't you mind," said Puddleglum. "There are no accidents. Our guide is Aslan; and he was there when the giant king caused the letters to be cut, and he knew already all things that would come of them; including this.”

“That’s true to life. Part of every misery is, so to speak, the misery’s shadow or reflection: the fact that you don’t merely suffer but have to keep on thinking about the fact that you suffer.”

“Emerson said, Do you love me? means Do you see the same truth?-Or at least, "Do you care about the same truth?”

“Failures are finger posts on the road to achievement.” 

“A man is never so proud as when striking an attitude of humility.”

“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.”

“The universe rings true whenever you fairly test it.”

“To enter heaven is to become more human than you ever succeeded in being on earth; to enter hell, is to be banished from humanity.”

“Till that word can be dug out of us, why should they hear the babble that we think we mean? How can they meet us face to face till we have faces?”

“In reading Chesterton, as in reading MacDonald, I did not know what I was letting myself in for. A young man who wishes to remain a sound Atheist cannot be too careful of his reading. There are traps everywhere — "Bibles laid open, millions of surprises," as Herbert says, "fine nets and stratagems." God is, if I may say it, very unscrupulous.”

“Last year, when he had been staying with the Pevensies, he had managed to hear them all talking of Narnia and he loved teasing them about it. He thought of course that they were making it all up; and as he was far too stupid to make anything up himself, he did not approve of that.”

“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.”

“When two humans have lived together for many years it usually happens that each has tones of voice and expressions of face which are almost unendurably irritating to the other. Work on that. Bring fully into the consciousness of your patient that particular lift of his mother's eyebrows which he learned to dislike in the nursery, and let him think how much he dislikes it. Let him assume that she knows how annoying it is and does it to annoy - if you know your job he will not notice the immense improbability of the assumption. And, of course, never let him suspect that he has tones and looks which similarly annoy her. As he cannot see or hear himself, this easily managed.”
