On the international horizon nations are engaged in a colossal and bitter contest for supremacy. Two world wars have been fought within a generation, and the clouds of another war are dangerously low. Man now has atomic and nuclear weapons that could within seconds completely destroy the major cities of the world. Yet the arms race continues and nuclear tests still explode in the atmosphere, with the grim prospect that the very air we breathe will be poisoned by radioactive fallout. Will these circumstances and weapons bring the annihilation of the human race?
When confronted by midnight in the social order we have in the past turned to science for help. And little wonder! On so many occasions science has saved us. When we were in the midnight of physical limitation and material inconvenience, science lifted us to the bright morning of physical and material comfort. When we were in the midnight of crippling ignorance and superstition, science brought us to the daybreak of the free and open mind. When we were in the midnight of dread plagues and diseases, science, through surgery, sanitation, and the wonder drugs, ushered in the bright day of physical health, thereby prolonging our lives and making for greater security and physical well-being. How naturally we turn to science in a day when the problems of the world are so ghastly and ominous.
But alas! science cannot now rescue us, for even the scientist is lost in the terrible midnight of our age. Indeed, science gave us the very instruments that threaten to bring universal suicide. So modern man faces a dreary and frightening midnight in the social order. — MLK, A Knock at Midnight
