If you can't explain it to a six year old, you don't understand it yourself.
Peace cannot be kept by force. It can only be achieved by understanding.
“Atticus, he was real nice..." <...>
"Most people are, Scout, when you finally see them."
It's ok to understand other people. But it's not enough. Advertence is necessary too. Because it's easy to understand abstract person if you're not a victim but outside observer. Imagine you say to friend who needs your help: "I understand the man who stole from you because he was starved". Or that: "I understand that scumbag who raped you because his wife ran out on him and he wanted to blow off steam". Only most hard-hearted person can say that.
Love involves a peculiar unfathomable combination of understanding and misunderstanding.
Those who go beneath the surface do so at their peril. Those who read the symbol do so at their peril.
