It's the never ending pursuit of knowledge. Without knowledge we live each day with fear, not knowing what to come, what to expect,  what to do.

With knowledge we understand the cruelty this world brings, the sadness, evil,  undesirable things we wished we didn't have to face. And how it bears down on our conscience knowing its out there but doing nothing to help it.

Here then presents the irony of a lifetime. To know and be depressed about our helplessness, or to not know and be helpless?
