1. What is supernatural? What is natural? I'm having trouble giving definitions to these words. What definition could we give these words? I have some ideas for defining these words, but I'm having second thoughts about them. I was thinking that we could call concepts that were supernatral as things without cause (internal cause), and concepts that are natural to be with cause (external cause). But, Quantum probabilities make things a little weird, unless you believe that there is a causal explaination not yet discovered. But in the case that Quantum Mechanics is true, that objects can behave randomly within the constraints of probability, what would one call it? 2. Can we call quantum physics natural or supernatural (if probability is truely a factor in nature)? Would it be a combination of both? 3. Could "supernatural/natural" the same as "acausal/causal" or "unknowable/knowable" or a combination of both? 4. Are these words metaphysical descriptions of the concepts or are they epistemological descriptions of the subject knowledge about the concept? 5. Or are these words completely meaningless?
