The world is everything that is the case
It is the opening line of a book by philosopher Ludwig Wittgenstein
http://en.wikipedia.org/wiki/Tractatus_ ... losophicus
It is also a biblical quote (I'm taking this from the internet so can't verify it)
The world is everything that holds us and satisfies us sensuously: that within us which has not known God (John 17:25).

Sylvian likes his philosophers I think, so I would go with that one.
Anyone else?
