“We have labored to produce a planet which, taken as a whole, would obey the Three Laws of Robotics. It does nothing to harm human beings, either by commission or omission. It does what we want it to do, as long as we do not ask it to harm human beings. And it protects itself, except at times and in places where it must serve us or save us even at the price of harm to itself. Nowhere else, neither on Earth nor in the other Spacer worlds, is this so nearly true as here on Aurora.”
