DOMAIN. So young Rossum said to himself: A man is something that, for instance, feels happy, plays the fiddle, likes going for walks, and, in fact, wants to do a whole lot of things that are really unnecessary. …But a working machine must not want to play the fiddle, must not feel happy, must not do a whole lot of other things. A petrol motor must not have tassels or ornaments, Miss Glory. And to manufacture artificial workers is the same thing as to manufacture motors. The process must be of the simplest, and the product of the best from a practical point of view. What sort of worker do you think is the best from a practical point of view?

HELENA. The best? Perhaps the one who is most honest and hardworking.

DOMAIN. No, the cheapest. The one whose needs are the smallest. Young Rossum invented a worker with the minimum amount of requirements. He had to simplify him. He rejected everything that did not contribute directly to the progress of work. In this way he rejected everything that makes man more expensive. In fact, he rejected man and made the Robot. My dear Miss Glory, the Robots are not people. Mechanically they are more perfect than we are, they have an enormously developed intelligence, but they have no soul.
