“The only ethical principle which has made science possible is that the truth shall be told all the time. If we do not penalize false statements made in error, we open up the way for false statements by intention. And a false statement of fact, made deliberately, is the most serious crime a scientist can commit.”

“You'd think (losing his job and degree for having made false claims as a researcher) would be a lesson to him," said Miss Hillyard. "It didn't pay, did it? Say he sacrificed his professional honour for the women and children we hear so much about -- but in the end it left him worse of."But that," said Peter, "was only because he committed the extra sin of being found out.”

“If God made everything, did He make the Devil?' This is the kind of embarrassing question which any child can ask before breakfast, and for which no neat and handy formula is provided in the Parents' Manual…Later in life, however, the problem of time and the problem of evil become desperately urgent, and it is useless to tell us to run away and play and that we shall understand when we are older. The world has grown hoary, and the questions are still unanswered.”

“I assure your lordship that for the first time in my existence I regret that I have made no practical study of campanology." I am always so delighted to find that there are things you cannot do.”

“Why do you want a letter from me? Why don't you take the trouble to find out for yourselves what Christianity is? You take time to learn technical terms about electricity. Why don't you do as much for theology? Why do you never read the great writings on the subject, but take your information from the secular 'experts' who have picked it up as inaccurately as you? Why don't you learn the facts in this field as honestly as your own field? Why do you accept mildewed old heresies as the language of the church, when any handbook on church history will tell you where they came from?Why do you balk at the doctrine of the Trinity - God the three in One - yet meekly acquiesce when Einstein tells you E=mc2? What makes you suppose that the expression "God ordains" is narrow and bigoted, while your own expression, "Science demands" is taken as an objective statement of fact?You would be ashamed to know as little about internal combustion as you know about Christian beliefs.I admit, you can practice Christianity without knowing much theology, just as you can drive a car without knowing much about internal combustion. But when something breaks down in the car, you go humbly to the man who understands the works; whereas if something goes wrong with religion, you merely throw the works away and tell the theologian he is a liar.Why do you want a letter from me telling you about God? You will never bother to check on it or find out whether I'm giving you personal opinions or Christian doctrines. Don't bother. Go away and do some work and let me get on with mine.”

“For God's sake, let's take the word 'possess' and put a brick round its neck and drown it ... We can't possess one another. We can only give and hazard all we have.”

“It is, of course, open to anyone to say that the whole idea is morbid and exaggerated--open even to those who think nothing of queuing for twenty-four hours in acute discomfort to see the first night of a musical comedy, which lasts three hours at most, which they are not sure of liking when they get there, and which they could see any other night with no trouble at all.”
