“There's no science that can't be used for good or for evil. Science could be used by whoever has the power to use it and desire to use it. If you make people knowledgeable about these sciences and don't point out this fact, then you're saying, I withdraw from the battle, from the discussion of the ethics involved. I just stick to the facts. And that of course means that you've surrendered to the strongest forces. You say you're neutral in what you do, you aren't that concerned with it. If the Pentagon is using your discoveries, that's not your problem. It's unavoidable that you have some responsibility, it seems to me, regardless of what you teach or what your subject is or what your skill is. Whatever you have to contribute has a social dimension. And I think it's ineffective to try to impose that on anybody. Sharing it with them is one thing, but trying to impose it is another. You honestly say these are my ideas and I have a right to my opinion, and if I have a right to my opinion then you have a right to your opinion."You can't have an individual right. It has to be a universal right. I have no rights that everybody else doesn't have. There's no right I could claim that anybody else in the world can't claim, and I have to fight for their exercising that right just like I have to fight for my own. That doesn't mean I have to impose my ideas on people, but it means I have a responsibility to provide whatever light I can on the subject and share my ideas with people.”
