Hope is invented to counter the debilitating effect of anxiety.
In the physical world, invention improves the living conditions, except of course those inventions that are used only to destroy. In the psychological world, invention distorts the mind, creates illusions, etc.
Insecurity is the prime mover in the world. All actions appear to stem from it, except those performed spontaneously.
Insecurity causes anxiety, which is fear of what might happen. Hope is the weapon to fight it with. But so long as the cause of insecurity is not found, fighting its consequences is a futile effort. It is a waste of energy. It is counter-productive. It is debilitating in the long run.
Fear is like a messenger: it comes bearing the information about the underlying cause of anxiety, of insecurity. Fighting it, or worse, the attempt to eliminate it, is like killing the messenger.
