After all, how did scientists approach their own research? The scientists all agreed: scientific research can't be stopped. If we don't build the bomb, someone else will. But then pretty soon the bomb was in the hands of new people, who said, if we don't use the bomb, someone else will. At which point, the scientists said, those people are terrible people, they're irrational and irresponsible. We scientists are okay. But those other people are a real problem. Yet the truth was that responsibility began with each individual person, and the choices he made. Each person had a choice.
