Once, when a religionist denounced me in unmeasured terms, I sent him a card saying, "I am sure you believe that I will go to hell when I die, and that once there I will suffer all the pains and tortures the sadistic ingenuity of your deity can devise and that this torture will continue forever. Isn't that enough for you? Do you have to call me bad names in addition?"

No one suggests that writing about science will turn the entire world into a model of judgment and creative thought. It will be enough if they spread the knowledge as widely as possible.

Having reached 451 books as of now doesn't help the situation. If I were to be dying now, I would be murmuring, "Too bad! Only four hundred fifty-one." (Those would be my next-to-last words. The last ones will be: "I love you, Janet.") [They were. -Janet.]

Today's science fiction is tomorrow's science fact.

The Three Laws of Robotics: 1: A robot may not injure a human being or, through inaction, allow a human being to come to harm; 2: A robot must obey the orders given it by human beings except where such orders would conflict with the First Law; 3: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law; The Zeroth Law: A robot may not harm humanity, or, by inaction, allow humanity to come to harm.

There is no right to deny freedom to any object with a mind advanced enough to grasp the concept and desire the state. -(from "The Bicentennial Man) story)

Aimless extension of knowledge, however, which is what I think you really mean by the term curiosity, is merely inefficiency. I am designed to avoid inefficiency.” -R. Daneel Olivaw
