“Man approaches God most nearly when he is in one sense least like God. For what can be more unlike than fullness and need, sovereignty and humility, righteousness and penitence, limitless power and a cry for help?”

“[The devil] always sends errors into the world in pairs--pairs of opposites. And he always encourages us to spend a lot of time thinking which is the worse. You see why, of course? He relies on your extra dislike of the one error to draw you gradually into the opposite one.”

“The Moral Law isn't any one instinct or any set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts. (...) The most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There's not one of them which won't make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it isn't. If you leave out justice you'll find yourself breaking agreements and faking evidence in trials 'for the sake of humanity,' and become in the end a cruel and treacherous man.”

“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.”

“A sum can be put right: but only by going back till you find the error and working it afresh from that point, never by simply going on.”

“When once a man is launched on such an adventure as this, he must bid farewell to hopes and fears, otherwise death or deliverance will both come too late to save his honor and his reason. Ho, my beauties!”

“I could never have gone far in any science because on the path of every science the lion Mathematics lies in wait for you.”

“In speaking of this desire for our own far off country, which we find in ourselves even now, I feel a certain shyness. I am almost committing an indecency. I am trying to rip open the inconsolable secret in each one of you—the secret which hurts so much that you take your revenge on it by calling it names like Nostalgia and Romanticism and Adolescence; the secret also which pierces with such sweetness that when, in very intimate conversation, the mention of it becomes imminent, we grow awkward and affect to laugh at ourselves; the secret we cannot hide and cannot tell, though we desire to do both. We cannot tell it because it is a desire for something that has never actually appeared in our experience. We cannot hide it because our experience is constantly suggesting it, and we betray ourselves like lovers at the mention of a name. Our commonest expedient is to call it beauty and behave as if that had settled the matter. Wordsworth’s expedient was to identify it with certain moments in his own past. But all this is a cheat. If Wordsworth had gone back to those moments in the past, he would not have found the thing itself, but only the reminder of it; what he remembered would turn out to be itself a remembering. The books or the music in which we thought the beauty was located will betray us if we trust to them; it was not in them, it only came through them, and what came through them was longing. These things—the beauty, the memory of our own past—are good images of what we really desire; but if they are mistaken for the thing itself they turn into dumb idols, breaking the hearts of their worshipers. For they are not the thing itself; they are only the scent of a flower we have not found, the echo of a tune we have not heard, news from a country we have never yet visited.”

“Well!' said Puddleglum, rubbing his hands. 'This is just what I needed. If these chaps don't teach me to take a serious view of life, I don't know what will.”

“Lightly men talk of saying what they mean. Often when he was teaching me to write in Greek the Fox would say, “Child, to say the very thing you really mean, the whole of it, nothing more or less or other than what you really mean; that’s the whole art and joy of words.” A glib saying. When the time comes to you at which you will be forced at last to utter the speech which has lain at the centre of your soul for years, which you have, all that time, idiot-like, been saying over and over, you’ll not talk about joy of words.”

“…the greatest service we can do to education today is to teach fewer subjects. No one has time to do more than a very few things well before he is twenty, and when we force a boy to be a mediocrity in a dozen subjects, we destroy his standards, perhaps for life.” 

“I’d rather be killed fighting for Narnia than grow old and stupid at home and perhaps go about in a bath-chair and then die in the end just the same.”

“The joy came from finding at last what hatred was made for.”

“No justification of virtue will enable a man to be virtuous. Without the aid of trained emotions the intellect is powerless against the animal organism. I had sooner play cards against a man who was quite skeptical about ethics, but bred to believe that ‘a gentleman does not cheat’, than against an irreproachable moral philosopher who had been brought up among sharpers.”

“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.”
