mapping the self onto the world

Robinson is able to survive his solitude because he is lucky; he makes peace with his condition because he is ordinary and his island is concrete. David, who was extraordinary, and whose island was virtual, finally had nothing but his own interesting self to survive on, and the problem with making a virtual world of oneself is akin to the problem with projecting ourselves onto a cyberworld: there's no end of virtual spaces in which to see stimulation, but their very endlessness, the perpetual stimulation without satisfaction, becomes imprisoning. 
From Jonathan Franzen's essay: Farther Away - Robinson Crusoe, David Foster Wallace, and the island of solitude.
