“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.”

“Reality, in fact, is usually something you could not have guessed. That is one of the reasons I believe Christianity. It is a religion you could not have guessed. If it offered us just the kind of universe we had always expected, I should feel we were making it up. But, in fact, it is not the sort of thing anyone would have made up. It has just that queer twist about it that real things have. So let us leave behind all these boys' philosophies--these over simple answers. The problem is not simple and the answer is not going to be simple either.”

“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.”

“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?”

“Welcome, Prince,' said Aslan. 'Do you feel yourself sufficient to take up the Kingship of Narnia?' I - I don't think I do, Sir,' said Caspian. 'I am only a kid.' Good,' said Aslan. 'If you had felt yourself sufficient, it would have been proof that you were not.”

“There are a dozen views about everything until you know the answer. Then there's never more than one.”

“I once read the sentence 'I lay awake all night with a toothache, thinking about the toothache an about lying awake.' 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. I not only live each endless day in grief, but live each day thinking about living each day in grief.”

“We know nothing of religion here: we only think of Christ.”

“...the sun looks down on nothing half so good as a household laughing together over a meal, or two friends talking over a pint of beer, or a man alone reading a book that interests him...”

“The world does not consist of 100 percent Christians and 100 percent non-Christians. There are people (a great many of them) who are slowly ceasing to be Christians but who still call themselves by that name: some of them are clergymen. There are other people who are slowly becoming Christians though they do not yet call themselves so. ”

“The change which the writing wrought in me (and of which I did not write) was only a beginning; only to prepare me for the gods' surgery. They used my own pen to probe my wound. ”

“I wrote this story for you, but when I began it I had not realized that girls grow quicker than books. As a result you are already too old for fairy tales, and by the time it is printed and bound you will be older still. But some day you will be old enough to start reading fairy tales again. You can then take it down from some upper shelf, dust it, and tell me what you think of it. I shall probably be too deaf to hear, and too old to understand a word you say, but I shall still be your affectionate Godfather, C. S. Lewis.”

“Prostitutes are in no danger of finding their present life so satisfactory that they cannot turn to God: the proud, the avaricious, the self-righteous, are in that danger.”

“There is no need to be worried by facetious people who try to make the Christian hope of ‘Heaven’ ridiculous by saying they do not want ‘to spend eternity playing harps’. The answer to such people is that if they cannot understand books written for grown-ups, they should not talk about them. All the scriptural imagery (harps, crowns, gold, etc.) is, of course, a merely symbolical attempt to express the inexpressible. Musical instruments are mentioned because for many people (not all) music is the thing known in the present life which most strongly suggests ecstasy and infinity. Crowns are mentioned to suggest the fact that those who are united with God in eternity share His splendour and power and joy. Gold is mentioned to suggest the timelessness of Heaven (gold does not rust) and the preciousness of it. People who take these symbols literally might as well think that when Christ told us to be like doves, He meant that we were to lay eggs.”

“No book is really worth reading at the age of ten which is not equally – and often far more – worth reading at the age of fifty and beyond.”
