“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?”

“What you see and what you hear depends a great deal on where you are standing. It also depends on what sort of person you are.”

“What he says, even on his knees, about his own sinfulness is all parrot talk. At bottom, he still believes he has run up a very favorable credit-balance in the Enemy's ledger by allowing himself to be converted, and thinks that he is showing great humility and condescension in going to church with these 'smug', commonplace neighbors at all.”

“I have received no assurance that anything we can do will eradicate suffering. I think the best results are obtained by people who work quietly away at limited objectives, such as the abolition of the slave trade, or prison reform, or factory acts, or tuberculosis, not by those who think they can achieve universal justice, or health, or peace. I think the art of life consists in tackling each immediate evil as well as we can.”

“No man knows how bad he is till he has tried very hard to be good. 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. After all, you find out the strength of the German army by fighting against it, not by giving in. You find out the strength of a wind by trying to walk against it, not by lying down. 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. We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means — the only complete realist.”

“We are always falling in love or quarreling, looking for jobs or fearing to lose them, getting ill and recovering, following public affairs. If we let ourselves, we shall always be waiting for some distraction or other to end before we can really get down to our work. The only people who achieve much are those who want knowledge so badly that they seek it while the conditions are still unfavorable. Favorable conditions never come.”

“...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...”

“Badness is only spoiled goodness.”

“Strictly speaking, there are no such things as good and bad impulses. Think...of a piano. It has not got two kinds of notes on it, the 'right' notes and the 'wrong' ones. Every single note is right at one time and wrong at another. The Moral Law is not any one instinct or set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts.”

“Like a good chess player, Satan is always trying to maneuver you into a position where you can save your castle only by losing your bishop.”

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

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

“The First [Friend] is the alter ego, the man who first reveals to you that you are not alone in the world by turning out (beyond hope) to share all your most secret delights. There is nothing to be overcome in making him your friend; he and you join like raindrops on a window. But the Second Friend is the man who disagrees with you about everything. He is not so much the alter ego as the antiself. Of course he shares your interests; otherwise he would not become your friend at all. But he has approached them all at a different angle. He has read all the right books but has got the wrong thing out of every one. It is as if he spoke your language but mispronounced it. How can he be so nearly right and yet, invariably, just not right? He is as fascinating (and infuriating) as a woman. When you set out to correct his heresies, you will find that he forsooth to correct yours! And then you go at it, hammer and tongs, far into the night, night after night, or walking through fine country that neither gives a glance to, each learning the weight of the other's punches, and often more like mutually respectful enemies than friends. Actually (though it never seems so at the time) you modify one another's thought; out of this perpetual dogfight a community of mind and a deep affection emerge.”

“I daren't come and drink," said Jill.  Then you will die of thirst," said the Lion. Oh dear!" said Jill, coming another step nearer."I suppose I must go and look for another stream then." There is no other stream," said the Lion.”

“God has no needs. Human love, as Plato teaches us, is the child of Poverty – of want or lack; it is caused by a real or supposed goal in its beloved which the lover needs and desires. But God's love, far from being caused by goodness in the object, causes all the goodness which the object has, loving it first into existence, and then into real, though derivative, lovability. God is Goodness. He can give good, but cannot need or get it. In that sense , His love is, as it were, bottomlessly selfless by very definition; it has everything to give, and nothing to receive.”
