„We have flown the air like birds and swum the sea like fishes, but have yet to learn the simple act of walking the earth like brothers.“
— Martin Luther King, Jr. American clergyman, activist, and leader in the American Civil Rights Movement 1929 - 1968
Context: 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.
