Why materialists are predominantly materialists

[Angrboda]

It's a subjective experience of what things are like, aka qualia. That they are not the same should be obvious by asking two questions:

1) Can you see what my brain's doing? Answer: Yes, to a degree
2) Can you see what I'm experiencing? Answer: No, not at all

This is simply begging the question.  We cannot currently see what it is that you are experiencing.  That doesn't mean we cannot in fact see what you are experiencing.  You're assuming your conclusion that brain function and experience are distinct.  If they are not, then there may come a day when I can "poke the redness in your brain."  And arguing that we cannot poke experience because we currently cannot is an argument from ignorance.

Are you saying that with a sufficiently advanced technology, one person could actually manipulate a second person's brain and as a result experience what the second person feels? If so then you are just supporting your point with wild speculation and issuing promissory notes. Bennyboy isn't making an argument from ignorance. He is simply pointing out that you have no evidence to support your theory.

By saying that we cannot see what you're experiencing, benny is making a claim about what is possible. No I don't know for sure that it is possible, but likewise he doesn't know for sure that it isn't possible. Yet here he is making the claim. Arguing that something is impossible because it's currently not possible is a classic argument from ignorance. It has absolutely zip to do with whether or not I have evidence that it is possible. He's making an absolute claim which he cannot support. You are simply wrong on this.
