These men were able to give the counsel they gave because they were operating at an enormous psychological distance from the people who would be maimed and killed by the weapons systems that would result from the ideas they communicated to their sponsors. The lesson, therefore, is that the scientist and technologist must, by acts of will and of the imagination, actively strive to reduce such psychological distances, to counter the forces that tend to remove him from the consequences of his actions. He must -- it is as simple as this -- think of what he is actually doing. He must learn to listen to his own inner voice. He must learn to say "No!"
Finally, it is the act itself that matters. When instrumental reason is the sole guide to action, the acts it justifies are robbed of their inherent meanings and thus exist in an ethical vacuum. I recently heard an officer of a great university publicly defend an important policy decision he had made, one that many of the university's students and faculty opposed on moral grounds, with the words: "We could have taken a moral stand, but what good would that have done?" But the moral good of a moral act inheres in the act itself. That is why an act can itself ennoble or corrupt the person who performs it. The victory of instrumental reason in our time has brought about the virtual disappearance of this insight and thus perforce the delegitimation of the very idea of nobility.

I have spoken here of what ought and ought not to be done, of what is morally repugnant, and of what is dangerous. I am, of course, aware of the fact that these judgements of mine have themselves no moral force except on myself. Nor, as I have already said, do I have any intention of telling other people what tasks they should and should not undertake. I urge them only to consider the consequences of what they do do. And here I mean not only, not even primarily, the direct consequences of their actions on the world about them. I mean rather the consequences on themselves, as they construct their rationalizations, as they repress the truths that urge them to different courses, and as they chip away at their own autonomy. That so many people ask what they must do is a sign that the order of being and doing has become inverted. Those who know who and what they are do not need to ask what they should do. And those who must ask will not be able to stop asking until they begin to look inside themselves. It it is everyone's task to show by example what questions one can ask of oneself, and to show that one can live with the few answers there are.

He watched on. Now that he had changed sides to the SS, he admired the strength of Fritz and the police man even more. He finally had left the camp of those who were wretched enough to let themselves be bludgeoned like that. He was glad to have made his choice. He did no longer have to fear the suspicion of the masters. He was on the side of good. The beatings the men received hardened his consciousness to embody good. One cannot receive beatings and be right, one cannot be dirty, eat garbage and be right.
