Isaac Asimov
- The Laws of Robotics
"We have: One, a robot may not injure a human being, or, through inaction, allow a human being to come to harm. Two," continued Powell, "a robot must obey the orders given it by human beings except where such orders would conflict with the First Law. And three, a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws."
