... Let us dare to face the situation. Man has become superman. He is a superman because he not only has at his disposal innate physical forces, but also commands, thanks to scientific and technological advances, the latent forces of nature which he can now put to his own use. To kill at a distance, man used to rely solely on his own physical strength; he used it to bend the bow and to release the arrow. The superman has progressed to the stage where, thanks to a device designed for the purpose, he can use the energy released by the combustion of a given combination of chemical products. This enables him to employ a much more effective projectile and to propel it over far greater distances.
However, the superman suffers from a fatal flaw. He has failed to rise to the level of superhuman reason which should match that of his superhuman strength. He requires such reason to put this vast power to solely reasonable and useful ends and not to destructive and murderous ones. Because he lacks it, the conquests of science and technology become a mortal danger to him rather than a blessing ...
But the essential fact which we should acknowledge in our conscience, and which we should have acknowledged a long time ago, is that we are becoming inhuman to the extent that we become supermen. We have learned to tolerate the facts of war: that men are killed en masse -some twenty million in the Second World War - that whole cities and their inhabitants are annihilated by the atomic bomb, that men are turned into living torches by incendiary bombs. We learn of these things from the radio or newspapers and we judge them according to whether they signify success for the group of peoples to which we belong, or for our enemies. When we do admit to ourselves that such acts are the results of inhuman conduct, our admission is accompanied by the thought that the very fact of war itself leaves us no option but to accept them. In resigning ourselves to our fate without a struggle, we are guilty of inhumanity.
What really matters is that we should all of us realize that we are guilty of inhumanity. The horror of this realization should shake us out of our lethargy so that we can direct our hopes and our intentions to the coming of an era in which war will have no place ...
