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 I give an interpretation of quantum logic in "A Theory of Quantum Space-time"Withdrawn as the term fuzzy is confusing and is no longer usedGeneral PhysicsQuantum Physicstext
