There are people who have lost every trace of human kindness.
The hardness of the human heart makes no sense.
Millions of people have decided not to be sensitive. They have grown thick skins around themselves just to avoid being hurt by anybody. But it is at great cost. Nobody can hurt them, but nobody can make them happy either.
I have a heart to be stabbed in or shot in, I have no doubt, and, of course, if it ceased to beat, I would cease to be. But you know what I mean. I have no softness there, no—sympathy—sentiment—nonsense.
My heart is turned to stone; I strike it, and it hurts my hand.
Hardness of heart is a dreadful quality, but it is doubtful whether in the long run it works more damage than softness of head.
It is a well-known fact that very often, putting the period of boyhood out of the argument, the older we grow the more cynical and hardened we become; indeed, many of us are only saved by timely death from moral petrification, if not from moral corruption.
One of the advantages or disadvantages of the way in which we live in these modern days is that we are ceasing to feel. That is to say we do not permit ourselves to be affected by either death or misfortune, provided these natural calamities leave our own persons unscathed.
