“There is no safe investment. To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly be broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements; lock it up safe in the casket or coffin of your selfishness. But in that casket – safe, dark, motionless, airless – it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. The alternative to tragedy, or at least to the risk of tragedy, is damnation. The only place outside Heaven where you can be perfectly safe from all the dangers and perturbations of love is Hell.”

“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 possessed your soul have been but hints of it -- tantalising glimpses, 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.”

“The home is the ultimate career. All other careers exist for one purpose, and that is to support the ultimate career.”

“You are told to love your neighbour as yourself. How do you love yourself? When I look into my own mind, I find that I do not love myself by thinking myself a dear old chap or having affectionate feelings. I do not think that I love myself because I am particularly good, but just because I am myself and quite apart from my character. I might detest something which I have done. Nevertheless, I do not cease to love myself. In other words, that definite distinction that Christians make between hating sin and loving the sinner is one that you have been making in your own case since you were born. You dislike what you have done, but you don't cease to love yourself. You may even think that you ought to be hanged. You may even think that you ought to go to the Police and own up and be hanged. Love is not affectionate feeling, but a steady wish for the loved person's ultimate good as far as it can be obtained.”

“At present we are on the outside… the wrong side of the door. We discern the freshness and purity of morning, but they do not make us fresh and pure. We cannot mingle with the pleasures we see. But all the pages of the New Testament are rustling with the rumor that it will not always be so. Someday, God willing, we shall get “in”… We will put on glory… that greater glory of which Nature is only the first sketch. We do not want to merely “see” beauty -- though, God knows, even that is bounty enough. We want something else which can hardly be put into words–to be united with the beauty we see, to pass into it, to receive it into ourselves, to bathe in it, to become part of it.”

“[M]an has been accustomed, ever since he was a boy, to having a dozen incompatible philosophies dancing about together inside his head. He doesn't think of doctrines as primarily "true" or "false," but as "academic" or "practical," "outworn" or "contemporary," "conventional" or "ruthless." Jargon, not argument, is your best ally in keeping him from the Church. Don't waste time trying to make him think that materialism is true! Make him think it is strong or stark or courageous—that it is the philosophy of the future. That's the sort of thing he cares about.”

“All that we call human history--money, poverty, ambition, war, prostitution, classes, empires, slavery--[is] the long terrible story of man trying to find something other than God which will make him happy.”

“Good and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of. An apparently trivial indulgence in lust or anger today is the loss of a ridge or railway line or bridgehead from which the enemy may launch an attack otherwise impossible.”

“We use a most unfortunate idiom when we say, of a lustful man prowling the streets, that he "wants a woman". Strictly speaking, a woman is just what he does not want. He wants a pleasure for which a woman happens to be the necessary piece of apparatus. How much he cares about the woman as such may be gauged by his attitude for her five minutes after fruition.”

“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?”

“Life is too deep for words, so don't try to describe it, just live it. Actually this quote doesn't sound like C.S. Lewis at all. Can anyone provide a source?”

“Every Christian would agree that a man's spiritual health is exactly proportional to his love for God.”

“Christ says, "Give me All. I don't want so much of your time and so much of your money and so much of your work: I want You. I have not come to torment your natural self, but to kill it. No half-measures are any good...Hand over the whole natural self, all the desires which you think innocent as well as the ones you think wicked--the whole outfit. I will give you a new self instead. In fact, I will give you Myself: my own will shall become yours.”

“Even in social life, you will never make a good impression on other people until you stop thinking about what sort of impression you're making.”

“The event of falling in love is of such a nature that we are right to reject as intolerable the idea that it should be transitory. In one high bound it has overleaped the massive of our selfhood; it has made appetite itself altruistic, tossed personal happiness aside as a triviality and planted the interests of another in the centre of our being. Spontaneously and without effort we have fulfilled the law (towards one person) by loving our neighbour as ourselves. It is an image, a foretaste, of what we must become to all if Love Himself rules in us without a rival. It is even (well used) a preparation for that.”
