For the record, it's not a personal attack to challenge someone to cough up something to support his or her claims. Nor is it considered a personal attack to question a person's credibility if it's relevant to the discussion, to point out that a person doesn't live according to his or her professed beliefs (since it's more an attack on said beliefs) or to state contempt for the tactics a person uses in a discussion, again if it's relevant. There was a
thread about this in Forum Management. My
reply on page 6 sums up my take on this.
Anyway--
Here's a simple rule of evidence: if X is consistent with theories A,B,C, then X cannot be evidence for theory A, B or C. For example, suppose the police have three suspects for a murder. Carpet fiber evidence comes in, and wouldn't you know it, all three suspects have the same brand and color of carpet. Because the evidence is consistent with all three suspects, it cannot be used as evidence to single out any of the three suspects. They can each point to the other when confronted by the "evidence".
Your analogy is failing already. We do not have evidence that is equally consistent with the suspects, rather we have your postulating the mere
possibility of alternate realities. Possibility does not equal plausibility, especially if that's all you have to go on, and you can't reasonably draw any conclusions about our current reality from purely speculative alternatives.
Again, if we had already discovered "glitches in the system" like in
The Matrix then you'd have good reason to hold these outside realities on equal footing. If however the illusion of reality were absolutely flawless, then it's really not a problem for materialism because this reality is all that's ever going to concern us, and the outside reality is never going to affect our lives in any meaningful way. Furthermore, the evidence we gather and conclusions we draw could only apply to the reality we live in, regardless of the illusion.
What you are essentially doing is insisting that we consider alternate suspects who happen to be intangible ghosts with ghost carpets, and then suggesting the fibers could have come from them as well.
Likewise, the information you get from your senses when you look at your wife is consistent with countless competeing theories of reality (a vivid dream, an experience machine, a computer simulation, an actual person, etc.). Yet you continue to cling to the idea that your sensory evidence is proof your wife is an actual person (and proof of materialism, overall). Since your sense-data is consistent with other competing realities, I could just as validly say that you seeing your wife every day is evidence of her being a dream figure (actually, that would be invalid, since the sense-data couldn't support any model of reality, but you get the point).
You didn't substantiate your countless competing theories of reality, you just asserted that they're possible without demonstrating how sense data could be consistent with them. By your logic, creationism and evolution are equally likely to be true and the evidence could fit either one, just because creationism has been brought up as a 'possible alternative.'
I see this in a lot of atheists- materialism is assumed from the get-go and evidence is then made to fit the theory, rather than the other way around. You continue to say "abuse of skepticism", but you are the one who can't seem to question your core beliefs. As I said, it's a curious intellectual blindspot I've noticed in strong theists/atheists.
You continue to appeal to your personal Pyrrhonic skepticism while failing to grasp that most skeptics around here regard skepticism as the demand for evidence, whether it concerns God, alternate realities, or whatever. Might the conclusions I currently accept be wrong? Of course they could. However it would take evidence to convince me, not the mere suggestion of the possibility of alternate realities, or the assertion that they somehow deserve an equal share of the same evidence.
If solipsism were true, then you'd better hope that the one true existent is an atheist. After all, an atheist would be far less likely to believe in his or her godlike powers and use them to wish you into the cornfield.
