The body at a particular point becomes the world and the world becomes a body. Consider the implications of spending time in bed as an instrument to explore our ideas about the world.

The first time that Ishmael saw Queequeg in Moby Dick, he observed how the savage preferred to keep his own company and enjoyed it so much that he was nearly oblivious to the presence of other men around him. That is, he displayed no need to engage in conversation, no need for standard social intercourse as a way of establishing his position in the hierarchy of things. In Queequeg he saw an example of an individual who had created a territory all of his own, with its own inner weather, with its own physics and logic.
