Practice 2　　We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a 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.　　Every man lives in two realms, the internal and the external. The internal is that realm of spiritual ends expressed in art, literature, morals and religion. The external is that complex of devices, techniques, mechanisms and instrumentalities by means of which we live. Our problem today is that we have allowed the internal to become lost in the external. We have allowed the means by which we live to outdistance the ends for which we live. So much of modern life can be summarized in that suggestive phrase of Thoreau: “Improved means to an unimproved end. “ This is the serious predicament, the deep and haunting problem, confronting modern man. Enlarged material powers spell enlarged peril if there is not proportionate growth of the soul. When the external of man’s nature subjugates the internal, dark storm clouds begin to form. (Martin Luther King: Where Do We Go from Here: Chaos or Community?)
