“And Elvex said, "I was the man." - In "Robot dreams" (Short story)”

“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.”

“They recognize the Master, now that I have preached Truth to them. All the robots do.”

“you just can't differentiate between a robot and the very best of humans.”

“A couple of months ago I had a dream, which I remember with the utmost clarity. (I don't usually remember my dreams.) I dreamed I had died and gone to Heaven. I looked about and knew where I was-green fields, fleecy clouds, perfumed air, and the distant, ravishing sound of the heavenly choir. And there was the recording angel smiling broadly at me in greeting. I said, in wonder, "Is this Heaven?" The recording angel said, "It is." I said (and on waking and remembering, I was proud of my integrity), "But there must be a mistake. I don't belong here. I'm an atheist." "No mistake," said the recording angel. "But as an atheist how can I qualify?" The recording angel said sternly, "We decide who qualifies. Not you." "I see," I said. I looked about, pondered for a moment, then turned to the recording angel and asked, "Is there a typewriter here that I can use?" The significance of the dream was clear to me. I felt Heaven to be the act of writing, and I have been in Heaven for over half a century and I have always known this.”

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

“The robot said, 'I have been trying, friend Julius, to understand some remarks Elijah made to me earlier. Perhaps I am beginning to, for it suddenly seems to me that the destruction of what should not be, that is, the destruction of what you people call evil, is less just and desirable than the conversion of thi sevil into what you call good.' He hesitated, then, almost as though he were surprised at his own owrds, he said, 'Go, and sin no more!”
