“Further up and further in” 

“All right, beautiful. You've got me tied down to this stone table, and there's a knife in your hand that says you get to rule Narnia for another hundred years. So maybe I die, and winter goes on. Maybe the hunger and the darkness and the fear never end. But as long as the children believe in me, I know that Aslan will live again. I, the Great Lion, Son of The Emperor Over The Sea, will live again and -- aaaaauugh!!”

“Can a mortal ask questions which God finds unanswerable? Quite easily, I should think. All nonsense questions are unanswerable. How many hours are in a mile? Is yellow square or round? Probably half the questions we ask - half our great theological and metaphysical problems - are like that.”

“But now I discovered the wonderful power of wine. I understood why men become drunkards. For the way it worked on me was not at all that it blotted out these sorrows, but that it made them seem glorious and noble, like sad music, and I somehow great and revered for feeling them.”

“Now we cannot...discover our failure to keep God's law except by trying our very hardest (and then failing). Unless we really try, whatever we say there will always be at the back of our minds the idea that if we try harder next time we shall succeed in being completely good. Thus, in one sense, the road back to God is a road of moral effort, of trying harder and harder. But in another sense it is not trying that is ever going tobring us home. All this trying leads up to the vital moment at which you turn to God and say, "You must do this. I can't.”

“Then I fell at his feet and thought, Surely this is the hour of death, for the Lion (who is worthy of all honour) will know that I have served Tash all my days and not him. Nevertheless, it is better to see the Lion and die than to be Tisroc of the world and live and not to have seen him. But the Glorious One bent down his golden head and touched my forehead with his tongue and said, Son, thou art welcome. But I said, Alas Lord, I am no son of thine but the servant of Tash. He answered, Child, all the service thou hast done to Tash, I account as service done to me. Then by reasons of my great desire for wisdom and understanding, I overcame my fear and questioned the Glorious One and said, Lord, is it then true, as the Ape said, that thou and Tash are one? The Lion growled so that the earth shook (but his wrath was not against me) and said, It is false. Not because he and I are one, but because we are opposites, I take to me the services which thou hast done to him. For I and he are of such different kinds that no service which is vile can be done to me, and none which is not vile can be done to him. Therefore if any man swear by Tash and keep his oath for the oath’s sake, it is by me that he has truly sworn, though he know it not, and it is I who reward him. And if any man do a cruelty in my name, then, though he says the name Aslan, it is Tash whom he serves and by Tash his deed is accepted. Dost thou understand, Child? I said, Lord, though knowest how much I understand. But I said also (for the truth constrained me), Yet I have been seeking Tash all my days. Beloved, said the Glorious One, unless thy desire had been for me thou wouldst not have sought so long and so truly. For all find what they truly seek.”

“Though no one would want to be sold as a slave, it is perhaps even more galling to be a sort of utility slave whom no one will buy.”

“I once read the sentence 'I lay awake all night with a toothache, thinking about the toothache an about lying awake.' That's true to life. Part of every misery is, so to speak, the misery's shadow or reflection: the fact that you don't merely suffer but have to keep on thinking about the fact that you suffer. I not only live each endless day in grief, but live each day thinking about living each day in grief.”

“All your life an unattainable ecstasy has hovered just beyond the grasp of your consciousness. The day is coming when you will wake to find, beyond all hope, that you have attained it, or else, that it was within your reach and you have lost it forever.”

“An open mind, in questions that are not ultimate, is useful. But an open mind about the ultimate foundations either of Theoretical or of Practical Reason is idiocy. If a man's mind is open on these things, let his mouth at least be shut. He can say nothing to the purpose. Outside the Tao there is no ground for criticizing either the Tao or anything else.”

“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?”

“Praise is the mode of love which always has some element of joy in it.”

“When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.”

“In reading great literature I become a thousand men and yet remain myself...I see with a myriad of eyes,but it is still I who see.”

“If you are really a product of a materialistic universe, how is it that you don't feel at home there?”
