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

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

“When you argue against Him you are arguing against the very power that makes you able to argue at all: it is like cutting off the branch you are sitting on.”

“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.”

“...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.”

“Of course, I quiet agree that the Christian religion is, in the long run, a thing of unspeakable discomfort. But it does not begin in comfort; it begins in the dismay and it is no use at all trying to go on to that comfort without first going through that dismay. In religion, as in war and everything else, comfort is one thing you cannot get looking for it. If you look for the truth, you may find comfort in the end: if you look for comfort you will not get either comfort or truth-only soft soap and wishful thinking to begin with and the in the end, despair.”

“Suppose... suppose we have only dreamed and made up these things like sun, sky, stars, and moon, and Aslan himself. In that case, it seems to me that the made-up things are a good deal better than the real ones. And if this black pits of a kingdom is the best you can make, then it's a poor world. And we four can make a dream world to lick your real one hollow.”

“It has actually become very necessary in our time to rebut the theory that every firm and serious friendship is really homosexual.”

“Alone among unsympathetic companions, I hold certain views and standards timidly, half ashamed to avow them and half doubtful if they can after all be right. Put me back among my Friends and in half an hour - in ten minutes - these same views and standards become once more indisputable. The opinion of this little circle, while I am in it, outweighs that of a thousand outsiders: as Friendship strengthens, it will do this even when my Friends are far away. For we all wish to be judged by our peers, by the men "after our own heart." Only they really know our mind and only they judge it by standards we fully acknowledge. Theirs is the praise we really covet and the blame we really dread.”

“And there's one thing about this underground work, we shan't get any rain.”

“The student is half afraid to meet one of the great philosophers face to face. He feels himself inadequate and thinks he will not understand him. But if he only knew, the great man, just because of his greatness, is much more intelligible than his modern commentator. The simplest student will be able to understand, if not all, yet a very great deal of what Plato said; but hardly anyone can understand some modern books on Platonism.”

“By the way, don't 'weep inwardly' and get a sore throat. If you must weep, weep: a good honest howl! I suspect we - and especially, my sex - don't cry enough now-a-days. Aeneas and Hector and Beowulf, Roland and Lancelot blubbered like schoolgirls, so why shouldn't we?”

“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.”

“A perfect man would never act from a sense of duty; he’d always want the right thing more than the wrong one. Duty is only a substitute for love (of God and of other people) like a crutch which is a substitute for a leg. Most of us need the crutch at times; but of course it is idiotic to use the crutch when our own legs (our own loves, tastes, habits etc.) can do the journey on their own.”

“The first demand any work of art makes upon us is surrender. Look. Listen. Receive. Get yourself out of the way. (There is no good asking first whether the work before you deserves such a surrender, for until you have surrendered you cannot possibly find out.)”
