- I have tried to move it with limited success to `sci.logic' where it belongs.
- However there is one aspect of the debate that I think is relevant to
- physics. It is my excuse for starting the debate here. There is a
- tendency today to see the continuum as a natural God given entity similar
- to how people once regarded Euclidian geometry. The Lowenheim and Skolem
- theorem shows that there is a certain arbitrariness to this concept.
