No. I stand by my claim that not capable of being demonstrated under any circumstance is equal to not existing.
In other words, you insist on claiming that you have knowledge that you cannot have, even in principle.
Because that's what existing is.
No, that's your redefinition that only works if you mix up subjective and objective.
You are still missing that point. I have not said that you claimed gravity leprechauns exist.
What is honest about claiming that they do? Or even that they might?
What is honest about claiming to have knowledge that you cannot have, even in principle?
Incoherent is precisely the word, though you can also substitute "self-contradictory" with equal validity. Again, it is the p-zombie issue: the definition contradicts itself, and thus the concept is incoherent.
It's not.
Because that's what real means.
Again, you you rather seem to be mixing up the concepts of what's reasonable to believe from a subjective perspective and what's actually the case.
If there is no relevant evidence obtainable, then it's not real.
That's what real means.
Only in your attempt to redefine it and justify yourself by invoking magic. Again, the physical limitations imposed by reality make it so that a lot of things that we could otherwise call real simply have no relevant evidence obtainable. That's certainly true in a larger sense when huge distances are the case. It's also true when it comes to dealing with things that are out of reach because of time effectively removing the data and evidence from being obtainable. The limits don't even remotely stop there, either. Again, the availability of relevant evidence matters for whether we have reason to accept that something is or is not the case. The simple lack of obtainable evidence does not automatically mean that something is not real.
Yes, there is.
There is a perfectly well-supported phenomenon that explains gravity (the curvature of spacetime in the presence of mass). There is no evidence - or any ability to procure evidence, even in theory - for gravity leprechauns.
That is evidence against them.
There is certainly reason to
favor the more useful explanation. However, if both explain the phenomena completely, no, the difference in usefulness is not evidence of truth. For that matter, as it stands, at last check, there were definite flaws in the current theories about gravity. Explanations similar to yours can potentially match the data better than the current prevailing theories match the data, in other words. They're simply not useful explanations, though, so they're not favored.
This entire thing was in response to jt512 saying that ESP may not be demonstrable, even in principle, but might still exist.
And that is certainly possible in concept, again, because of the physical limitations that reality imposes upon us. In such a case we would have no good reason to accept that it is the case, certainly.
For clarity's sake: ...to gather relevant information, even in principle.
Again, the "to gather" is the point which we seem to be having significant disagreement with here. If we cannot, even in principle, make the tools that would be required to gather that relevant information because of the limitations imposed by reality, we're not going to be able to gather that information. You've repeatedly tried to invoke magic to get around the point that reality imposes limitations on what can actually be done in a number of ways, but have been rather inconsistent about what you want to allow your magic to be applied to.
Yes, it is.
Something that is not true is false.
Sure, something that is not true can be considered false. The complete lack of relevant information means that one simply
doesn't know which it is, though. You're trying really, really hard to claim to have knowledge that you cannot have, even in principle. Do you, in fact, think that claiming to have information that you do not have is honest behavior?
An empty denial.
1) X exists.
2) X doesn't exist.
No valid chain of logic in between. That sure sounds like contradictory assertion to me.
