Clarification request for irrational precepts #6 and #13
6. Belief in psychics/paranormal/supernatural claims
13. The claim that mystical experiences can give us knowledge.
While, in general, I agree that many if not most such claims are false, and that belief in them is irrational, I think that the terms are used with enough variability to leave some room for legitimate claims to be potentially categorized as paranormal/supernatural/mystical... in which case, I would say that it's possible to have a justifiable, rational belief in such claims after seeing evidence to support them.
For example, the term supernatural is often used in these forums to mean anything that's outside of nature, and therefore nonexistent... but that definition is highly open to interpretation (as different people might disagree on what is included in nature, and therefore exists). So then, some people might label a specific claim as being supernatural when others would not.
So, I'd like to request that specific definitions be provided for the terms psychic, paranormal, supernatural, mystical, and knowledge that, if possible, wouldn't leave too much room for disagreement over which claims they include.
