“When things go wrong, you'll find they usually go on getting worse for some time; but when things once start going right they often go on getting better and better.”

“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.”

“Have you ever noticed,” said Dimble, “that the universe, and every bit of the universe is always hardening and narrowing and coming to a point?”His wife waited as those wait who know by long experience the mental processes of the person who is talking to them.“I mean this,” said Dimble in answer to the question she had not asked. “If you dip into any college, or school, or parish, or family – anything you like – at a given point in its history, you always find that there was a time before that point when there was more elbow room and contrasts weren’t quite so sharp; and that there’s going to be a time after that point when there is even less room for indecision and choices are even more momentous. Good is always getting better and bad is always getting worse: the possibilities of even apparent neutrality are always diminishing. The whole thing is sorting itself out all the time, coming to a point, getting sharper and harder.”

“We all want progress. But progress means getting nearer to the place where you want to be. And if you have taken a wrong turning then to go forward does not get you any nearer. If you are on the wrong road progress means doing an about-turn and walking back to the right road and in that case the man who turns back soonest is the most progressive man. There is nothing progressive about being pig-headed and refusing to admit a mistake. And I think if you look at the present state of the world it's pretty plain that humanity has been making some big mistake. We're on the wrong road. And if that is so we must go back. Going back is the quickest way on.”

“Once a King in Narnia, always a King in Narnia. But don't go trying to use the same route twice. Indeed, don't try to get there at all. It'll happen when you're not looking for it. And don't talk too much about it even among yourselves. And don't mention it to anyone else unless you find that they've had adventures of the same sort themselves. What's that? How will you know? Oh, you'll know all right. Odd things, they say-even their looks-will let the secret out. Keep your eyes open. Bless me, what do they teach them at these schools."-The Professor”

“A sum can be put right: but only by going back till you find the error and working it afresh from that point, never by simply going on.”
