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

“The quest of the Inner Ring will break your hearts unless you break it. But if you break it, a surprising result will follow. If in your working hours you make the work your end, you will presently find yourself all unawares inside the only circle in your profession that really matters. You will be one of the sound craftsmen, and other sound craftsmen will know it. This group of craftsmen will by no means coincide with the Inner Ring or the Important People or the People in the Know. It will not shape that professional policy or work up that professional influence which fights for the profession as a whole against the public: nor will it lead to those periodic scandals and crises which the Inner Ring produces. But it will do those things which that profession exists to do and will in the long run be responsible for all the respect which that profession in fact enjoys and which the speeches and advertisements cannot maintain. And if in your spare time you consort simply with the people you like, you will again find that you have come unawares to a real inside: that you are indeed snug and safe at the center of something which, seen from without, would look exactly like an Inner Ring. But the difference is that its secrecy is accidental, and its exclusiveness a by-product, and no one was led thither by the lure of the esoteric: for it is only four or five people who like one another meeting to do things that they like. This is friendship. Aristotle placed it among the virtues. It causes perhaps half of all the happiness in the world, and no Inner Ring can ever have it.”

“Love may, indeed, love the beloved when her beauty is lost: but not because it is lost. Love may forgive all infirmities and love still in spite of them: but Love cannot cease to will their removal. Love is more sensitive than hatred itself to every blemish in the beloved… Of all powers he forgives most, but he condones least: he is pleased with little, but demands all.”

“Experience: that most brutal of teachers. But you learn, my God do you learn.”

“The next best thing to being wise oneself is to live in a circle of those who are.”

“If people do not believe in permanent marriage, it is perhaps better that they should live together unmarried than that they should make vows they do not mean to keep. It is true that by living together without marriage they will be guilty (in Christian eyes) of fornication. But one fault is not mended by adding another; unchastity is not improved by adding perjury. The idea that 'being in love' is the only reason for remaining married really leaves no room for marriage as a contract or promise at all. If love is the whole thing, then the promise can add nothing; and if it adds nothing, then it should not be made.”

“The sight of the huge world put mad ideas into me, as if I could wander away, wander forever, see strange and beautiful things, one after the other to the world's end.”

“As long as you are proud you cannot know God. A proud man is always looking down on thing and people: and, of course, as long as you are looking down you cannot see something that is above you.”

“If a man thinks he is not conceited, he is very conceited indeed.”

“A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is... A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness. They have lived a sheltered life by always giving in.”

“No man can be an exile if he remembers that all the world is one city.”

“Miracles do not, in fact, break the laws of nature.”

“Girls aren't very good at keeping maps in their brains", said Edmund, "That's because we've got something in them", replied Lucy.”

“And yet all loneliness, angers, hatreds, envies, and itchings that (Hell) contains, if rolled into one single experience and put into the scale against the least moment of the joy that is felt by the least in Heaven, would have no weight that could be registered at all. Bad cannot succeed even in being bad as truly as good is good.”

“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.”
