I have been discussing Dickens simply in terms of his ‘message’, and almost ignoring his literary qualities. But every writer, especially every novel… - George Orwell

Adults are only less superstitious than children in proportion as they have more power over their environment. In predicaments where everyone is powerless (eg war, gambling) everyone is superstitious

Paddy and I had scarcely a wink of sleep, for there was a man near us who had some nervous trouble, shell-shock perhaps, which made him cry out 'Pip!' at irregular intervals. It was a loud, startling noise, something like the toot of a small motor-horn. You never knew when it was coming, and it was a sure preventer of sleep. ...he must have kept ten or twenty people awake every night. He was an example of the kind of thing that prevents one from ever getting enough sleep when men are herded as they are in these lodging houses.'

A scrupulous writer, in every sentence that he writes, will ask himself at least four questions, thus:

1. What am I trying to say?
2. What words will express it?
3. What image or idiom will make it clearer?
4. Is this image fresh enough to have an effect?

And he will probably ask himself two more:
1. Could I put it more shortly?
2. Have I said anything that is avoidably ugly?

But you are not obliged to go to all this trouble. You can shirk it by simply throwing your mind open and letting the ready-made phrases come crowding in. They will construct your sentences for you — even think your thoughts for you, to a certain extent — and at need they will perform the important service of partially concealing your meaning even from yourself.
