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."Computer Power and Human Reason: From Judgment To Calculation" (1976)
I cannot tell why the spokesmen I have cited want the developments I forecast to become true. Some of them have told me that they work on them for the morally bankrupt reason that "If we don't do it, someone else will." They fear that evil people will develop superintelligent machines and use them to oppress mankind, and that the only defense against these enemy machines will be superintelligent machines controlled by us, that is, by well-intentioned people. Others reveal that they have abdicated their autonomy by appealing to the "principle" of technological inevitability. But, finally, all I can say with assurance is that these people are not stupid. All the rest is mystery.
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."Computer Power and Human Reason: From Judgment to Calculation"
If the teacher, if anyone, is to be an example of a whole person to others, he must first strive to be a whole person. Without the courage to confront one's inner as well as one's outer worlds, such wholeness is impossible to achieve. Instrumental reason alone cannot lead to it.
The salvation of the world depends only on the individual whose world it is. At least, every individual must act as if the whole future of the world, of humanity itself, depends on him. Anything less is a shirking of responsibility and is itself a dehumanizing force, for anything less encourages the individual to look upon himself as a mere actor in a drama written by anonymous agents, as less than a whole person, and that is the beginning of passivity and aimlessness.
