“Child, to say the very thing you really mean, the whole of it, nothing more or less or other than what you really mean; that's the whole art and joy of words.”

“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?”

“It is a good rule after reading a new book, never to allow yourself another new one till you have read an old one in between.”

“They stormed and jeered at one another in long meaningless words of about twenty syllables each.”

“Oh, I'm a dangerous criminal, I am,' said the dwarf cheerfully.”

“Hell is a state of mind - ye never said a truer word. And every state of mind, left to itself, every shutting up of the creature within the dungeon of its own mind - is, in the end, Hell. But Heaven is not a state of mind. Heaven is reality itself. All that is fully real is Heavenly. For all that can be shaken will be shaken and only the unshakeable remains.”

“You weren't a decent man and you didn't do your best. We none of us were and none of us did.”

“who can duly adore that Love which will open the high gates to a prodigal who is brought in kicking, struggling, resentful, and darting his eyes in every direction for a chance of escape? The words compelle intrare, compel them to come in, have been so abused by wicked men that we shudder at them; but, properly understood, they plumb the depth of the Divine mercy. The hardness of God is kinder than the softness of man, and His compulsion is our liberation.”

“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.”

“One always feel better when one has made up one's mind.”

“Make your choice, adventurous Stranger, Strike the bell and bide the danger, Or wonder, till it drives you mad, What would have followed if you had.”

“I have learned now that while those who speak about one's miseries usually hurt, those who keep silence hurt more.” 

“An odd by-product of my loss is that I’m aware of being an embarrassment to everyone I meet. At work, at the club, in the street, I see people, as they approach me, trying to make up their minds whether they’ll ‘say something about it’ or not. I hate it if they do, and if they don’t. Some funk it altogether. R. has been avoiding me for a week. I like best the well brought-up young men, almost boys, who walk up to me as if I were a dentist, turn very red, get it over, and then edge away to the bar as quickly as they decently can. Perhaps the bereaved ought to be isolated in special settlements like lepers.”

“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?”

“Love may forgive all infirmities and love still in spite of them: but Love cannot cease to will their removal.”
