Children do not understand technologies like printed encyclopedias and telephone directories.

It seemed like there was nothing science could not do. The advance of medicine has given us a dangerous population growth; the advance of technology has given us a growing pollution danger; a group of ivory-tower, head-in-the-clouds physicists have given us the nuclear bomb; and so on and so on and so on.Science was going to bring us to a grand and glorious Utopian future. Science unleashed unspeakable horrors, there were things man was not meant to know, and one started to see more and more dystopias in science fiction literature. But at exactly which point in time did the disillusionment with the "goodness" of science come? Could it have come at the time when some scientist or scientists demonstrated the evil in science beyond any doubt; showed mankind a vision of evil so intense that not only the scientist himself but all of science was darkened past the point where it could be washed clean again?Even now there is some nostalgia for this view, the technical term is "Retro-Futurism". When was the sin of the scientist committed, then, and who was the scientist? It was to that which Oppenheimer referred in his remark on sin. The nuclear bomb is a terrible thing that has contributed immeasurably to the insecurity of mankind and to his growing distrust of science, but the nuclear bomb is by no means pure evil.For on the Somme while generals thought they could build a bridge of mangled flesh across the trenches.Everything about the carnage was horrible, but was there anything which managed to make itself felt above that sickening spectacle of mutual suicide?
