“Above all, do not attempt to use science (I mean, the real sciences) as a defence against Christianity. They will positively encourage him to think about realities he can’t touch and see. ”

“My dear young lady,' said the professor...'there is one plan which no one has yet suggested and which is well worth trying.' 'What's that?' said Susan. 'We might all try minding our own business...”

“As the uneasiness and reluctance to face it cut him off more and more from all real happiness, and as habit renders the pleasures the vanity and excitement and flippancy at once less pleasant and harder to forgo...you will find that anything or nothing is sufficient to attract his wandering attention. You no longer need a good book, which he really likes, to keep him from his prayers or his work or his sleep; a column of advertisements in yesterday's paper will do. You can make him waste his time not only in conversation he enjoys with people whom he likes, but also in conversations with those he cares nothing about, on subjects that bore him. You can make him do nothing at all for long periods. You can keep him up late at night, not roistering, but staring at a dead fire in a cold room. All the healthy and outgoing activities which we want him to avoid can be inhibited and nothing given in return, so that at last he may say...'I now see that I spent most my life doing in doing neither what I ought nor what I liked.”

“Whatever their bodies do affects their souls. It is funny how mortals always picture us as putting things into their minds: in reality our best work is done by keeping things out...”

“Whenever all men are...hastening to be slaves or tyrants we make Liberalism the prime bogey.”

“Our struggle is--isn't it?--to achieve and retain faith on a lower level. To believe that there is a Listener at all. For as the situation grows more and more desperate, the grisly fears intrude. Are we only talking to ourselves in an empty universe? The silence is often so emphatic. And we have prayed so much already”

“It is a good rule after reading a new book, never to allow yourself another new one till you have read an old one in between.”

“What do people mean when they say, 'I am not afraid of God because I know He is good'? Have they never even been to a dentist?”

“When I'm older I'll understand" said Lucy, " I am older and I don't think I want to understand", replied Edmund”

“Perhaps my bad temper or my jealousy are gradually getting worse - so gradually that the increase in seventy years will not be very noticeable. But it might be absolute hell in a million years!”

“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.”

“In Gethsemane the holiest of all petitioners prayed three times that a certain cup might pass from Him. It did not.”

“The hardness of God is kinder than the softness of men, and His compulsion is our liberation.”

“No thanks," said Digory, "I don't know that I care much about living on and on after everyone I know is dead. I'd rather live an ordinary time and die and go to Heaven.”

“If conversion to Christianity makes no improvement in a man's outward actions – if he continues to be just a snobbish or spiteful or envious or ambitious as he was before – then I think we must suspect that his 'conversion' was largely imaginary; and after one's original conversion, every time one thinks one has made an advance, that is the test to apply. Fine feelings, new insights, greater interest in 'religion' mean nothing unless they make our actual behavior better; just as in an illness 'feeling better' is not much good if the thermometer shows that your temperature is still going up. In that sense the outer world is quite right to judge Christianity by its results. Christ told us to judge by results. A tree is known by its fruit; or, as we say, the proof of the pudding is in the eating. When we Christians behave badly, or fail to behave well, we are making Christianity unbelievable to the outside world. The war-time posters told us that Careless Talk costs Lives. It is equally true that Careless Lives cost Talk. Our careless lives set the outer world taking; and we give them grounds for talking in a way that throws doubt on the truth of Christianity itself.”
