Imagine that virtual reality equipment eventually becomes so good that it can simulate sound, smell, taste, and touch as well as sight when you are wearing it. Imagine, too, that the programming becomes so elaborate that you can have week-long virtual reality experiences, not just brief encounters. Under those circumstances, would you be willing to give up real-world interactions with other people and settle for virtual reality fantasies? Why? Why not? What is there about an engagement with the real world that is missing from a virtual reality experience? Does everything we know come from the senses?
2. Many ethical thinkers have called for a worldwide ban on all forms of human cloning. Do you agree with the this argument? Could we realistically allow therapeutic cloning but ban human cloning? What are the ethical questions raised by cloning? And is there any moral difference between applying genetic engineering techniques to humans and applying them to animals or plants? Explain.
