From Chan's post :
"In his 1964 Nobel Lecture at Oslo, Norway, Martin Luther King Jr reminded us to not let our "moral progress" fall behind our progress in science and technology. He said:
Yet, in spite of these spectacular strides in science and technology, and still unlimited ones to come, something basic is missing. There is a sort of poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually. We have learned to fly the air like birds and swim the sea like fish, but we have not learned the simple art of living together as brothers.You can read the full text of the speech here at Nobelprize.org .

This is the serious predicament, the deep and haunting problem confronting modern man. If we are to survive today, our moral and spiritual "lag" must be eliminated. Enlarged material powers spell enlarged peril if there is not proportionate growth of the soul. When the "without" of man's nature subjugates the "within", dark storm clouds begin to form in the world."
