“I could never have gone far in any science because on the path of every science the lion Mathematics lies in wait for you.”

“When he was a young man he prayed constantly for chastity; but years later he realized that while his lips had been saying 'Oh Lord, make me chaste,' his heart had been secretly adding, 'But please don't do it just yet.”

“Die before you die, there is no chance after.”

“This is one of the miracles of love: It gives a power of seeing through its own enchantments and yet not being disenchanted.”

“Friendship ... is born at the moment when one man says to another "What! You too? I thought that no one but myself . . .” 

“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.”

“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 great wisdom can be reached without sacrifice.”

“For what you see and hear depends a good deal on where you are standing: it also depends on what sort of person you are.”

“In reading great literature I become a thousand men and yet remain myself. Like the night sky in the Greek poem, I see with a myriad eyes, but it is still I who see.”

“It is a serious thing to live in a society of possible Gods and Goddesses. To remember that the dullest, and most uninteresting person you can talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship.”

“You never know how much you really believe anything until its truth or falsehood becomes a matter of life and death to you.”

“And grief still feels like fear. Perhaps, more strictly, like suspense. Or like waiting; just hanging about waiting for something to happen. It gives life a permanently provisional feeling. It doesn't seem worth starting anything. I can't settle down. I yawn, fidget, I smoke too much. Up till this I always had too little time. Now there is nothing but time. Almost pure time, empty successiveness.”

“In each of my friends there is something that only some other friend can fully bring out. By myself I am not large enough to call the whole man into activity; I want other lights than my own to show all his facets... Hence true Friendship is the least jealous of loves. Two friends delight to be joined by a third, and three by a fourth, if only the newcomer is qualified to become a real friend. They can then say, as the blessed souls say in Dante, "Here comes one who will augment our loves." For in this love "to divide is not to take away.”

“I sometimes think that shame, mere awkward, senseless shame, does as much towards preventing good acts and straightforward happiness as any of our vices can do.”
