On fairy tales ( and, for me, this relates to some other fantasy books and movies and tales...) ~
"Those who say that children must not be frightened may mean two things.
They may mean 1) that we must not do anything likely to give the child those haunting, disabling, pathological fears against which ordinary courage is helpless: in fact, Phobias. His mind must, if possible, be kept clear of things he can't bear to think of.
Or they may mean 2) that we must try to keep out of his mind the knowledge that he is born into a world of death, violence, wounds, adventure, heroism and cowardice, good and evil.
If they mean the first I agree with them; but not if they mean the second. The second would indeed be to give children a false impression and feed them on escapism in the bad sense. Since it is so likely that they will meet cruel enemies, let them at least have heard of brave knights and heroic courage. Other wise you are making their destiny not brighter but darker."
