Some would add intimacy and expression of love. There are also secondary purposes, such as providing employment, or to obtain physical protection. Nozick is sceptical that we would plug in to such a machine. First, we want to do certain things, it is only because we want to do the actions that we want the experiences of doing them or thinking that we've done them . . . A second reason for not plugging in is that we want to be a certain way, to be a certain sort of person.

Thirdly, plugging into an experience machine limits us to a man-made world, to a world no deeper or more important than that which people can construct. There is no actual contact with any deeper reality, though the experience of it can be simulated. 1 Nozick makes two claims. The first, that we should not connect to such a machine, I will address later. His second claim is that we would not connect.
