“I do not think that all who choose wrong roads perish; but their rescue consists in being put back on the right road. A sum can be put right: but only by going back til you find the error and working it afresh from that point, never by simply going on. Evil can be undone, but it cannot 'develop' into good. Time does not heal it. The spell must be unwound, bit by bit, 'with backward mutters of dissevering power' --or else not.”

“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.”

“True humility is not thinking less of yourself; it is thinking of yourself less.”

“Being in love is a good thing, but it is not the best thing. There are many things below it, but there are also things above it. You cannot make it the basis of a whole life. It is a noble feeling, but it is still a feeling. Now no feeling can be relied on to last in its full intensity, or even to last at all. Knowledge can last, principles can last, habits can last but feelings come and go. And in fact, whatever people say, the state called ‘being in love’ usually does not last. If the old fairy-tale ending ‘They lived happily ever after’ is taken to mean ‘They felt for the next fifty years exactly as they felt the day before they were married,’ then it says what probably never was nor ever would be true, and would be highly undesirable if it were. Who could bear to live in that excitement for even five years? What would become of your work, your appetite, your sleep, your friendships? But, of course, ceasing to be ‘in love’ need not mean ceasing to love. Love in this second sense — love as distinct from ‘being in love’ — is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriages) the grace which both partners ask, and receive, from God. They can have this love for each other even at those moments when they do not like each other; as you love yourself even when you do not like yourself. They can retain this love even when each would easily, if they allowed themselves, be ‘in love’ with someone else. ‘Being in love’ first moved them to promise fidelity: this quieter love enables them to keep the promise. it is on this love that the engine of marriage is run: being in love was the explosion that started it.”

“No emotion is, in itself, a judgement; in that sense all emotions and sentiments are alogical. but they can be reasonable or unreasonable as they conform to Reason or fail to conform. The heart never takes the place of the head: but it can, and should, obey it.”

“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.”

“You don’t think – not possibly – not as a mere hundredth chance – there might be things that are real though we can’t see them? … If there are souls, could there not be soul-houses?”

“One of the reasons why it needs no special education to be a Christian is that Christianity is an education itself.”

“Surely what a man does when he is taken off his guard is the best evidence for what sort of man he is.”

“In writing. Don't use adjectives which merely tell us how you want us to feel about the thing you are describing. I mean, instead of telling us a thing was "terrible," describe it so that we'll be terrified. Don't say it was "delightful"; make us say "delightful" when we've read the description. You see, all those words (horrifying, wonderful, hideous, exquisite) are only like saying to your readers, "Please will you do my job for me."

“Good and evil both increase at compound interest.”

“A man who first tried to guess 'what the public wants,' and then preached that as Christianity because the public wants it, would be a pretty mixture of fool and knave”

“You and I who still enjoy fairy tales have less reason to wish actual childhood back. We have kept its pleasures and added some grown-up ones as well.”

“Every age has its own outlook. It is specially good at seeing certain truths and specially liable to make certain mistakes. We all, therefore, need the books that will correct the characteristic mistake of our own period. And that means the old books.”

“Friendship, then, like the other natural loves, is unable to save itself. In reality, because it is spiritual and therefore faces a subtler enemy, it must, even more wholeheartedly than they, invoke the divine protection if it hopes to remain sweet. For consider how narrow its true path is. Is must not become what the people call a "mutual admiration society"; yet if it is not full of mutual admiration, of Appreciative love, it is not Friendship at all.”
