It's bloody-stupid is what it is. If you understood how your own consciousness works on a scientific level, you would know exactly what evidence to check for in other people to know whether they're conscious or not. You could perform a simple medical test to find out if someone's a p-zombie (hint: they definitely aren't).
You clearly aren't very introspective, too bad. That doesn't warrant the idea as bloody stupid. You cannot verify consciousness, only reactiveness. Maybe you are confused by medical consciousness versus consciousness in a real sense. Medical consciousness only means reactiveness, it's a misnomer
'It's only appearances' skepticism always includes "to me". It only works by induction on the skeptic's solipsism. The difficulty of your position is compounded by HN's interface - even the claim "it appears to me that you are made of meat" is implausible.
Even with solipsism you can easily say that I'm made of meat. On the other hand, saying your consciousness is entirely meat-based is hugely addumptive. You will not know until you are dead, if there's something more.
Conscious in a medical sense, where the brain acts as if it has separate consciousness, yes. But that's not what this problem is about.
Rather it is about consciousness in the philosophical sense, that starts with the question of whether or not anything outside of your own consciousness even exists, and if we posit the existence of a real world, whether or not other seemingly thinking, self-aware, conscious entities exists that are able to experience consciousness.
Since we don't know what gives rise to this form of consciousness, it is not evident whether or not there will ever be any evidence to determine whether they are conscious or not in that sense.
I believe Eli is coming from a position of: reality is made up of things that can be studied, and rules that are universal, and those things and rules are what gives rise to consciousness in me. If I understand the process that gives rise to consciousness in me, I can look at other people's brains and see whether the process would apply in them as well.
"Consciousness in the philosophical sense", to the extent that it's a meaningful thing to talk about, is part of reality.
>"Consciousness in the philosophical sense", to the extent that it's a meaningful thing to talk about, is part of reality.
Stronger statement: "consciousness in the philosophical sense" is either part of reality, or a meaningless construct invented by philosophers to justify metaphysical speculations, thus obtaining job security by having a permanent claim that some phenomenon actually exists that can never be reduced to science.

Leaving aside the difficulties in unpacking the idea of scientific introspection under the classical rubric of experiment as observation, once one decomposes consciousness to where a scientific level can be extracted, there's a corpse on the table not a patient. The whole gist of consciousness is that it's unified and once we admit a distinct 'scientific level' we ought to own up to what we have done and say "by consciousness I don't mean what is ordinarily meant, but instead I mean exactly 'x,y,z' and therefore my claims are not about consciousness in general but about this special definition."
And there's nothing wrong with that, and it might be useful.
To continue with the above thread, wouldn't Wittgenstein's response to this be something along the lines of: if scientifically dissecting consciousness results in a corpse, is it correct to say there was a body in the first place? Think of the question, "How does Helios pull the Sun across the sky?" After dissection, we resolve to question the question, not answer it.
See the "Mary's room" thought experiment. Thinking and reasoning about all the measurable properties of a phenomenon is way different than experiencing them. This doesn't necessarily mean that subjective perceptions have an immaterial existence, but it provides an approach to analyzing the mind that can't be achieved by physical measurement alone.
A better question would be "how can you try to understand consciousness without instrospection?" Studying consciousness merely by performing brain scans and electroencephalograms, without asking the subject what she's experiencing, would surely provide a poor and incomplete perspective.
