   We are becoming as a nation, as a world, indeed, atom-conscious. Many of us are already afflicted with atomphobia, though so far it has manifested itself only in a mirage of autoaeromotive discs and a war of words between chronic optimists and empirical pessimists concerning civilization’s probable future.

   People often call me an optimist, because I show them the enormous progress they didn't know about. That makes me angry. I'm not an optimist. That makes me sound naive. I'm a very serious “possibilist”. That’s something I made up. It means someone who neither hopes without reason, nor fears without reason, someone who constantly resists the overdramatic worldview. As a possibilist, I see all this progress, and it fills me with conviction and hope that further progress is possible. This is not optimistic. It is having a clear and reasonable idea about how things are. It is having a worldview that is constructive and useful.;
