“A moderately bad man knows he is not very good: a thoroughly bad man thinks he is alright. This is common sense really. You understand sleep when you are awake, not well you are sleeping.”

“When a man is getting better he understands more and more clearly the evil that is still left in him. When a man is getting worse he understands his own badness less and less.”

“No man knows how bad he is till he has tried very hard to be good. A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is. After all, you find out the strength of the German army by fighting against it, not by giving in. You find out the strength of a wind by trying to walk against it, not by lying down. A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness — they have lived a sheltered life by always giving in. We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means — the only complete realist.”

“If you do not take the distinction between good and bad very seriously, then it is easy to say that anything you find in this world is a part of God. But, of course, if you think some things really bad, and God really good, then you cannot talk like that. You must believe that God is separate from the world and that some of the things we see in it are contrary to His will.”

“A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is... A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness. They have lived a sheltered life by always giving in.”

“You can be good for the mere sake of goodness; you cannot be bad for the mere sake of badness. You can do a kind action when you are not feeling kind and when it gives you no pleasure, simply because kindness is right; but no one ever did a cruel action simply because cruelty is wrong - only because cruelty is pleasant or useful to him, In other words, badness cannot succeed even in being bad in the same way in which goodness is good. Goodness is, so to speak, itself: badness is only spoiled goodness. And there must be something good first before it can be spoiled.”

“The more we believe that God hurts only to heal, the less we can believe that there is any use in begging for tenderness. A cruel man might be bribed...But suppose that what you are up against is a surgeon whose intentions are wholly good. The kinder and more conscientious he is, the more inexorably he will go on cutting. If he yielded to your entreaties, if he stopped before the operation was complete, all the pain up to that point would have been useless. But is it credible that such extremities of torture should be necessary for us? Well, take your choice. The tortures occur. If they are unnecessary, then there is no God or a bad one. If there is a good God, then these tortures are necessary. For no even moderately good Being could possibly inflict or permit them if they weren't. Either way, we're for it.”
