Open eyes

For so many years I thought that the problem of humanity was not to perceive the Good, to realize now that that is not enough, that more serious than that is not to perceive the Evil. 

Not to perceive both is to be blind. 
To perceive only the Good is to be one-eyed. 
To perceive both the Good and the Evil is to have both eyes open.
