Scenario: Imagine two people, Jones and Smith. Jones and Smith are friends and co-workers and neighbors! One day, Jones tells Smith that he is so happy with his life. His wife and kids love him, his co-workers are all super friendly and respect him, and he gets along super well with the neighbors. Smith agrees with Jones that this is all wonderful. He says, smiling, "We are both lucky that way." Suppose that Jones know that, in fact, none of these things are true about Smith. There are rumors circulating both at work and among the neighbors that smith's wife is unfaithful to him. Smith's kids, who are friends with Jones' kids, regularly complain about what terrible father he is, and Smith's co-workers all say that Smith doesn't pull his weight at the office and hate working with him. Smith however, seems oblivious to all of this and seems to think his life is the same as Jones' life.
Suppose further that for Jones, all of these things really ARE true. So while both men have the idea that their lives are a certain way, only one of them has beliefs that truly reflect reality (Jones).

Think about Jones and Smith. They are both equally happy but only Jones's beliefs about his life are accurate, while Smith is deceived about his own life. Do you think there are any important differences between their lives? Would it matter to you whether you were living Jones's versus Smith's life (assuming you never discovered which one you were living)? Why or why not?

How does this story (of Jones and Smith) tie back to Nozick's "Experience Machine?"
