ABSTRACT
Those who realize the peril involved in the possibility of nuclear weapons have a very grave responsibility. The dangers are new, and the kind of thinking that they demand is also new. If mankind is to survive in the nuclear age, it can only be by the prevention of large-scale wars. This is a difficult end to achieve. And if it is to be achieved in spite of the prejudices and mental habits of populations and politicians, it will have to be approached by stages and with comprehension of opposing points of view.
