To paraphrase MLK,

We have to look much deeper to find the real cause of humanities problems and ills. If we are to really find it, I think we would have to look into the hearts and souls of men. The trouble isn't so much that our scientific genius lags behind, but our moral genius lags behind. We haven't learned how to be just, and honest, and kind, and true, and loving. The great danger today is not so much the nuclear weapons you can put in an airplane and drop on the heads of a hundreds of thousands, as dangerous as that is. But the great danger confronting civilization today is that atomic bomb which lies in the hearts and souls of men.
