“In a properly automated and educated world, then, machines may prove to be the true humanizing influence. It may be that machines will do the work that makes life possible and that human beings will do all the other things that make life pleasant and worthwhile ”

“A robot may not injure a human being, or, through inaction, allow a human being to come to harm.”

“Surely, if we take on thinking partners––or, at the least, thinking servants––in the form of machines, we will be more comfortable with them, and will relate to them more easily, if they are shaped like humans. It will be easier to be friends with human-shaped robots than with specialized machines of unrecognizable shape. And I sometimes think that, in the desperate straits of humanity today, we would be grateful to have nonhuman friends, even if they are only the friends we build ourselves.”

“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.”

“Congratulations on the new library, because it isn't just a library. It is a space ship that will take you to the farthest reaches of the Universe, a time machine that will take you to the far past and the far future, a teacher that knows more than any human being, a friend that will amuse you and console you -- and most of all, a gateway, to a better and happier and more useful life.[Letters of Note; Troy (MI, USA) Public Library, 1971]”

“One might suppose that reality must be held to at all costs. However, though that may be the moral thing to do, it is not necessarily the most useful thing to do. The Greeks themselves chose the ideal over the real in their geometry and demonstrated very well that far more could be achieved by consideration of abstract line and form than by a study of the real lines and forms of the world; the greater understanding achieved through abstraction could be applied most usefully to the very reality that was ignored in the process of gaining knowledge.”

“Life is pleasant. Death is peaceful. It's the transition that's troublesome.”
