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

“He's not safe, but he's good (referring to Aslan, the Lion, in The Lion, the Witch and the Wardrobe)”

“and a charge of lying against someone whom you have always found truthful is a very serious thing; a very serious thing indeed.”

“But Ransom, as time wore on, became aware of another and more spiritual cause for his progressive lightening and exultation of heart. A nightmare, long engendered in the modern mind by the mythology that follows in the wake of science, was falling off him. He had read of 'Space': at the back of his thinking for years had lurked the dismal fancy of the black, cold vacuity, the utter deadness, which was supposed to separate the worlds. He had not known how much it affected him till now-now that the very name 'Space' seemed a blasphemous libel for this empyrean ocean of radiance in which they swam. He could not call it 'dead'; he felt life pouring into him from it every moment. How indeed should it be otherwise, since out of this ocean all the worlds and all their life had come? He had thought it barren: he now saw that it was the womb of worlds, whose blazing and innumerable offspring looked down nightly even upon the earth with so many eyes-and here, with how many more! No: Space was the wrong name.”

“Do not be deceived, Wormwood. Our cause is never more in danger than when a human, no longer desiring, but still intending, to do our Enemy's will, looks round upon a universe from which every trace of Him seems to have vanished, and asks why he has been forsaken, and still obeys.”

“Daughter of Eve from the far land of Spare Oom where eternal summer reigns around the bright city of War Drobe, how would it be if you came and had tea with me?”

“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.”
