from nobel peace prize acceptance speech
1952
albert schweitzer

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, 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, 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.
in this context is it not significant that the first great scientific discovery, the harnessing of the force resulting from the combustion of gunpowder, was seen at first only as a means of killing at a distance?
