Scientists can ask me about what the experience of "red" is like, and I can tell them that it's not quite like blue or green, and can point to it, but the experience itself (like all experience) remains a completely private matter for me.

Most emphatically, no. Well, I suppose yes, for now, but that's only because your complete brain state is effectively hidden from the scientist because we don't have the technology to get a good picture of what's going on inside. Give us a decent real time high resolution scanner, and your "private" experience is just another data set on a big computer somewhere.

A C++ program would be pretty damn inscrutable, too, if we couldn't core dump when things went wrong...

Look at any red object and compare it with any "scientific" description regarding wavelengths and retinas, neurons, synapses, neurotransmitters, visual cortexes, atoms, molecules, or what have you. Clearly none of these thing are in any way related to what it's actually like for you to see that red object.

Look at any Youtube video and compare it with the "computer science" description, with bits and bytes and encodings, filtered through the Flash player, etc. One could argue that these things are clearly unrelated to some kid getting whacked in the nuts by his brother, but one would be wrong.

I'm extremely reluctant to accept the notion that our physical brains have no relation to how we experience the world (an idea you seem eager to accept) - we don't understand it very well, true, but that's partially because we're pretty stupid, and partially because we're not very far along in understanding it yet.

All that it takes for you to claim subjective experience is for your brain to be programmed to respond to the question "Do you have subjective experience of the color red?" in the affirmative. To me, that's a lot easier to swallow that that's the case than to imagine there's Magic going on here...and yup, I'm happy to apply the same logic to my own experience, I don't attribute anything special to it other than a mere self-reinforcing computational delusion.

Personally, I find that a far more fascinating thing than the alternative, anyways...

Now, you may well believe that what's going on when you look at a red object is "really" some interaction between what those scientific terms describe in some model of what's going on with your brain, sensory organs, etc. But this requires a sort of suspension of disbelief, as you have to set aside your actual "subjective" experience of the red object itself

It really doesn't, though, unless you already ascribe something mystical and aphysical to this "subjective experience," begging the question.

Someone else brought up the idea of a pzombie, someone that responds in every way as if they had subjective experience, but really doesn't. Getting past WTF that would actually mean, since nobody ever bothers to define "subjective experience," I think the heart of the question is this: if a pzombie responds internally as if it had subjective experience as well as externally, then isn't that enough for us to say that it does? That's why I'm happy to write the whole thing off as a non-issue, even when thinking about my own experience - the fact that I believe I experience "red" means nothing more than that I believe it.

IMO anyone arguing against that first has to figure out what it means for a pzombie to lack subjective experience even though it looks, walks, talks, acts, and thinks as if it did. Otherwise the argument is pretty pointless, kind of like asking what the world would be like if the prime number theorem was false.
