Ben Estes knew he was going to die and it didn't make him feel any better to know that that was the chance he had lived with all these years. - Isaac Asimov

But he no longer feared the fear! It was not something to run from, that fear, but something to fight.

"It is a mistake," he said, " to suppose that the public wants the environment protected or their lives saved and that they will be grateful to any idealist who will fight for such ends. What the public wants is their own individual comfort. We know that well enough from our experience in the environmental crisis of the twentieth century. Once it was well known that cigarettes increased the incidence of lung cancer, the obvious remedy was to stop smoking, but the desired remedy was a cigarette that did not cause cancer. When it became clear that the internal-combustion engine was polluting the atmosphere dangerously, the obvious remedy was to abandon such engines, and the desired remedy was to develop non-polluting engines."

Even as a youngster, though, I could not bring myself to believe that if knowledge presented danger, the solution was ignorance. To me, it always seemed that the solution had to be wisdom. You did not refuse to look at danger, rather you learned how to handle it safely. After all, this has been the human challenge since a certain group of primates became human in the first place. Any technological advance can be dangerous. Fire was dangerous from the start, and so (even more so) was speech — and both are still dangerous to this day — but human beings would not be human without them.
