“You are guilty of no evil, Ransom of Thulcandra, except a little fearfulness. For that, the journey you go on is your pain, and perhaps your cure: for you must be either mad or brave before it is ended.”

“Every time you make a choice you are turning the central part of you, the part of you that chooses, into something a little different than it was before. And taking your life as a whole, with all your innumerable choices, all your life long you are slowly turning this central thing into a heavenly creature or a hellish creature: either into a creature that is in harmony with God, and with other creatures, and with itself, or else into one that is in a state of war and hatred with God, and with its fellow creatures, and with itself. To be the one kind of creature is heaven: that is, it is joy and peace and knowledge and power. To be the other means madness, horror, idiocy, rage, impotence, and eternal loneliness. Each of us at each moment is progressing to the one state of the other.”

“Logic!" said the Professor half to himself. "Why don't they teach logic at these schools? There are only three possibilities. Either your sister is telling lies, or she is mad, or she istelling the truth. You know she doesn't tell lies and it is obvious that she is not mad. For the moment then and unless any further evidence turns up, we must assume that she is telling the truth.”

“The time when there is nothing at all in your soul except a cry for help may be just that time when God can't give it: you are like the drowning man who can't be helped because he clutches and grabs. Perhaps your own reiterated cries deafen you to the voice you hoped to hear.”

“If you are foe, we do not fear you. If you are friend, your foes will be taught the fear of us.”

“When you meet me here again, you will have come to stay. But not now. You must go back to your own world for a while.”

“It is not fore nothing that you are named Ransom.”
