“…the greatest service we can do to education today is to teach fewer subjects. No one has time to do more than a very few things well before he is twenty, and when we force a boy to be a mediocrity in a dozen subjects, we destroy his standards, perhaps for life.” 

“If no set of moral ideas were truer or better than any other, there would be no sense in preferring civilised morality to savage morality.”

“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 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.”

“Devils are depicted with bats' wings and good angels with birds' wings, not because anyone holds that moral deterioration would be likely to turn feathers into membrane, but because most men like birds better than bats.”

“For every one pupil who needs to be guarded from a weak excess of sensibility there are three who need to be awakened from the slumber of cold vulgarity”

“I have no duty to be anyone's Friend and no man in the world has a duty to be mine. No claims, no shadow of necessity. Friendship is unnecessary, like philosophy, like art, like the universe itself (for God did not need to create). It has no survival value; rather it is one of those things which give value to survival.”

“Please,' she said, 'You're so beautiful. You may eat me if you like. I'd rather be eaten by you than fed by anyone else.”

“Humour is...the all-consoling and...the all-excusing, grace of life.”

“Need-love says of a woman, "I cannot live without her"; Gift-love longs to give her happiness, comfort, protection...appreciative love gazes and holds its breath and is silent, rejoices that such a wonder should exist even if not for him, will not be wholly dejected by losing her, would rather have it so than never to have seen her at all.”

“If you thirst you may drink.”

“The most precious gift that marriage gave me was the constant impact of something very close and intimate, yet all the time unmistakably other, resistant - in a word, real.”

“You can't know, you can only believe - or not.”

“We may give our human loves the unconditional allegiance which we owe only to God. They they become gods: then they become demons. Then they will destroy us, and also destroy themselves. For natural loves that are allowed to become gods do not remain loves. They are still called so, but can become in fact complicated forms of hatred.”

“Christianity, if false, is of no importance, and if true, of infinite importance, the only thing it cannot be is moderately important.”
