“Alone among unsympathetic companions, I hold certain views and standards timidly, half ashamed to avow them and half doubtful if they can after all be right. Put me back among my Friends and in half an hour - in ten minutes - these same views and standards become once more indisputable. The opinion of this little circle, while I am in it, outweighs that of a thousand outsiders: as Friendship strengthens, it will do this even when my Friends are far away. For we all wish to be judged by our peers, by the men "after our own heart." Only they really know our mind and only they judge it by standards we fully acknowledge. Theirs is the praise we really covet and the blame we really dread.”

“Remember that there are only three kinds of things anyone need ever do. (1) Things we ought to do (2) Things we've got to do (3) Things we like doing. I say this because some people seem to spend so much of their time doing things for none of these three reasons, things like reading books they don't like because other people read them.”

“The great difficulty is to get modern audiences to realize that you are preaching Christianity solely and simply because you happen to think it true; they always suppose you are preaching it because you like it or think it good for society or something of that sort. Now a clearly maintained distinction between what the Faith actually says and what you would like it to have said or what you understand or what you personally find helpful or think probable, forces your audience to realize that you are tied to your data just as the scientist is tied by the results of the experiments; that you are not just saying what you like. This immediately helps them realize that what is being discussed is a question about objective fact — not gas about ideals and points of view.”

“Free will, though it makes evil possible, also makes possible any love or goodness or joy worth having.”

“Thomas Aquinas said of suffering, as Aristotle had said of shame, that it was a thing not good in itself; but a thing which might have a certain goodness in particular circumstances. That is to say, if evil is present, pain at recognition of the evil, being a kind of knowledge, is relatively good.”

“Don't use words too big for the subject. Don't say infinitely when you mean very; otherwise you'll have no word left when you want to talk about something really infinite.”

“Those who are enjoying something, or suffering something, together, are companions. Those who enjoy or suffer one another, are not.”

“We are all receiving Charity. There is something in each of us that cannot be naturally loved.”

“Each time you fall He'll pick you up. He knows your own efforts are never going to bring you anywhere near perfection”

“No soul that seriously and constantly desires joy will ever miss it. Those who seek find. To those who knock it is opened.”

“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...”

“Life is too deep for words, so don't try to describe it, just live it. Actually this quote doesn't sound like C.S. Lewis at all. Can anyone provide a source?”

“Poetry most often communicates emotions, not directly, but by creating imaginatively the grounds for those emotions. It therefore communicates something more than the emotion; only by means of that something more does it communicate the emotion at all.”

“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.”

“The promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love. A promise must be about things that I can do, about actions: no one can promise to go on feeling in a certain way. He might as well promise to never have a headache or always to feel hungry.”
