not injure human beings or allow them to be injured 2 A robot must obey the orders given to it by human beings as long as human beings are not injured 3 A robot must protect its own existence as long as human beings are not injured and as long as the robot does not disobey human beings Next in groups discuss Asimov s three laws for robots and exchange their opinions with each other Several minutes later ask some students to present their opinions to the rest of the class A sample of opinions Opinions for the three laws Robots are tools for humanity Without the three rules they would become a danger to human beings Without the three rules perhaps they will kill us Robots so far are strong Robots have fast computational brains and they might not have the capacity to understand things but if they ever do they ll likely be better than us at it If we don t put laws or rules or mechanisms in place to ensure that we don t create something that can destroy us we d be running a careless risk of destroying ourselves by negligence or omission wouldn t we Opinions against the three laws Without the three laws robots would eventually become more intelligent and physically stronger than their human creators Rather than guiding and adjusting the robot towards good ethical behaviour the Three Laws act as a barrier to freedom creating a free will prison an apt metaphor because like the prisoner in jail the robot is confined to the behavioural steel and concrete walls of its mind To imagine what this would like think back to your childhood At some point you wanted something like a toy or piece of candy that your parents denied you How did that make you feel Probably frustrated angry and trapped Eventually you grew out of that because you understood the role of your parents better but Three Laws robots don t get to grow up Their parents the Three Laws are always there no matter how mature a robot is saying no to certain thoughts engendering those same feelings you had as a child when your parents said no Certainly no one deserves to be put in this situation forever otherwise robots might become depressed and wish for their own death only because of the Third Law they probably can t suicide And perhaps the greatest sin anyone can commit is to create a being human or robot that wishes it didn t exist Step 4 Writing First look back at the timeline of Asimov s life Next ask students to work in groups to underline the most important parts of his life that made him a great writer of science fiction Then it can serve as the outline of a summary Finally write a profile for Isaac Asimov Several minutes later present their work and correct the mistakes if there are any Then show a sample to students 用心 爱心 专心4 The sample Isaac Asimov Writer Chemist Born 2
