Testing a Hypothesis about the Supernatural

[robvalue]

If we can only observe the effects of the supernatural and can never investigate the supernatural itself, then any supernatural cause is indistinguishable from any other; or from no supernatural cause at all.

That's the problem. People generally define these things so that they can't be disproven; but by doing so, they can't be proven either.

The only sensible definition, I think, is things going on outside of our self-enclosed environment (assuming there is an outside). Otherwise, it's just "unknown" or gibberish.
