Came across a quote from a young lad struggling with his path of enlightenment...

"One of the most difficult things in life is understanding that some things are beyond our understanding"

Accepting ignorance with an optimistic view is no more than a cop out.  Maybe that's too black and white but I refuse to allow laziness and our brain's reaction:

let's just put a label on it so we can make some rational sense out of it

the human brain hates the unknown

so we label things to comprehend it all
