  This paper is withdrawn as I am no longer using the term "fuzzy space- time"
to describe the uncertainty in co-ordinate systems implicit in quantum logic.
Nor am I using the interpretation that quantum logic can be regarded as a
special case of fuzzy logic. This is because there are sufficient differences
between quantum logic and fuzzy logic that the explanation is confusing. I give
an interpretation of quantum logic in "A Theory of Quantum Space-time"
