“Indeed the safest road to Hell is the gradual one--the gentle slope, soft underfoot, without sudden turnings, without milestones, without signposts,...Your affectionate uncle, Screwtape.”

“Like a good chess player, Satan is always trying to maneuver you into a position where you can save your castle only by losing your bishop.”

“No justification of virtue will enable a man to be virtuous. Without the aid of trained emotions the intellect is powerless against the animal organism. I had sooner play cards against a man who was quite skeptical about ethics, but bred to believe that ‘a gentleman does not cheat’, than against an irreproachable moral philosopher who had been brought up among sharpers.”

“Certainly, Lu. Whatever you like,' said Peter unexpectedly. This was encouraging, but as Peter instantly rolled round and went to sleep again it wasn't much use.”

“Am I lost or just less found?”

“The Moral Law isn't any one instinct or any set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts. (...) The most dangerous thing you can do is to take any one impulse of your own nature and set it up as the thing you ought to follow at all costs. There's not one of them which won't make us into devils if we set it up as an absolute guide. You might think love of humanity in general was safe, but it isn't. If you leave out justice you'll find yourself breaking agreements and faking evidence in trials 'for the sake of humanity,' and become in the end a cruel and treacherous man.”

“Faith, in the sense in which I am here using the word, is the art of holding on to things your reason has once accepted, in spite of your changing moods.”

“There was a boy called Eustace Clarence Scrubb, and he almost deserved it.”

“We cannot understand. The best is perhaps what we understand least.”

“You may have noticed that the books you really love are bound together by a secret thread. You know very well what is the common quality that makes you love them, though you cannot put it into words: but most of your friends do not see it at all, and often wonder why, liking this, you should also like that. Again, you have stood before some landscape, which seems to embody what you have been looking for all your life; and then turned to the friend at your side who appears to be seeing what you saw -- but at the first words a gulf yawns between you, and you realise that this landscape means something totally different to him, that he is pursuing an alien vision and cares nothing for the ineffable suggestion by which you are transported. Even in your hobbies, has there not always been some secret attraction which the others are curiously ignorant of -- something, not to be identified with, but always on the verge of breaking through, the smell of cut wood in the workshop or the clap-clap of water against the boat's side? Are not all lifelong friendships born at the moment when at last you meet another human being who has some inkling (but faint and uncertain even in the best) of that something which you were born desiring, and which, beneath the flux of other desires and in all the momentary silences between the louder passions, night and day, year by year, from childhood to old age, you are looking for, watching for, listening for? You have never had it. All the things that have ever deeply possessed your soul have been but hints of it -- tantalising glimpses, promises never quite fulfilled, echoes that died away just as they caught your ear. But if it should really become manifest -- if there ever came an echo that did not die away but swelled into the sound itself -- you would know it. Beyond all possibility of doubt you would say "Here at last is the thing I was made for". We cannot tell each other about it. It is the secret signature of each soul, the incommunicable and unappeasable want, the thing we desired before we met our wives or made our friends or chose our work, and which we shall still desire on our deathbeds, when the mind no longer knows wife or friend or work. While we are, this is. If we lose this, we lose all.”

“When you are behaving as if you loved someone, you will presently come to love him. If you injure someone you dislike, you will find yourself disliking him more. If you do him a good turn, you will find yourself disliking him less.”

“The First [Friend] is the alter ego, the man who first reveals to you that you are not alone in the world by turning out (beyond hope) to share all your most secret delights. There is nothing to be overcome in making him your friend; he and you join like raindrops on a window. But the Second Friend is the man who disagrees with you about everything. He is not so much the alter ego as the antiself. Of course he shares your interests; otherwise he would not become your friend at all. But he has approached them all at a different angle. He has read all the right books but has got the wrong thing out of every one. It is as if he spoke your language but mispronounced it. How can he be so nearly right and yet, invariably, just not right? He is as fascinating (and infuriating) as a woman. When you set out to correct his heresies, you will find that he forsooth to correct yours! And then you go at it, hammer and tongs, far into the night, night after night, or walking through fine country that neither gives a glance to, each learning the weight of the other's punches, and often more like mutually respectful enemies than friends. Actually (though it never seems so at the time) you modify one another's thought; out of this perpetual dogfight a community of mind and a deep affection emerge.”

“The sin both of men and of angels, was rendered possible by the fact that God gave us free will.”

“Nothing you have not given away will ever really be yours.”
