In many parts of the world, especially Pakistan and Afghanistan, terrorism, war and conflict stop children to go to their schools. We are really tired of these wars. Women and children are suffering.
We had a little slave boy whom we had hired from some one, there in Hannibal. He was from the Eastern Shore of Maryland, and had been brought away from his family and his friends, half way across the American continent, and sold. He was a cheery spirit, innocent and gentle, and the noisiest creature that ever was, perhaps. All day long he was singing, whistling, yelling, whooping, laughing - it was maddening, devastating, unendurable. At last, one day, I lost all my temper, and went raging to my mother, and said Sandy had been singing for an hour without a single break, and I couldn't stand it, and wouldn't she please shut him up.The tears came into her eyes, and her lip trembled, and she said something like this - 'Poor thing, when he sings, it shows that he is not remembering, and that comforts me; but when he is still, I am afraid he is thinking, and I cannot bear it. He will never see his mother again; if he can sing, I must not hinder it, but be thankful for it. If you were older, you would understand me; then that friendless child's noise would make you glad.' It was a simple speech, and made up of small words, but it went home, and Sandy's noise was not a trouble to me any more.
There's always moral instruction whether the writer inserts it deliberately or not. The least effective moral instruction in fiction is that which is consciously inserted. Partly because it won't reflect the storyteller's true beliefs, it will only reflect what he BELIEVES he believes, or what he thinks he should believe or what he's been persuaded of. But when you write without deliberately expressing moral teachings, the morals that show up are the ones you actually live by. The beliefs that you don't even think to question, that you don't even notice-- those will show up. And that tells much more truth about what you believe than your deliberate moral machinations.
