It was on fire when I laid down on it.
That is why Kathryn's post is so perfect, it is the only known moral law that would cease all ill will against each other.
However the reason it doesn't work is because not everyone love's God or themselves the same way others do.
First step is to define what Love means. What a can of worms that is though.
Within the context of my Christian beliefs, I believe that man is a fallen creature, so you are exactly right - man does not love others as he loves himself.
A moral code is a goal we should strive toward, in my opinion. And the moral code of Christianity is to love God and love your neighbor as yourself. Now whether or not individuals actually DO that is another matter altogether!
