"Suppose there is an iron house, which has no windows and is indestructible. There are many sleeping people inside, and they will soon die of suffocation. However, as they pass from sleep to death, they do not feel the sorrow of dying.
Now that you are shouting loudly and startling a few more sober people, causing these unfortunate few to suffer the irreparable pain of death, do you think you are worthy of them? "
"But now that a few people are up, you can't say that there is absolutely no hope of destroying this iron house."
