Because you believe the physical firing of C-fibres is exactly the same thing as feeling pain, scientifically study the C-fibres and you understand 'what it is like' to feel pain too?
Well, if a cluster of C-fibers were sitting in a petri dish and firing, that wouldn't be pain in my view. Pain is something a fully embodied organism experiences, in a proper context.
Ok, so you think pain is real when C-fibres fire in a human body.
Richard Rorty once wrote (and I paraphrase), "Once you've described everything that happens, you're done".
Applying this principle to consciousness, once you have a theory or series of theories which tells you what kinds of things are happening in people's bodies that lead them to perform various motor activities, up to and including reports about what they are experiencing in whatever detail you care for them to do so, you're done. You've explained consciousness. That's it, there's nothing more for you to do.
But that's not how the scientific method works. it doesn't ask people how they feel about gravity to formulate a scientific Theory of Gravity. It doesn't just say stuff moves about like this, job done. It comes up with a theory of gravity which offers an explanation which enables testable predictions. And tries to tie in with the existing scientific model of how the world works. Which results in people going off to look for evidence of gravitons. And knowledge increases, theories are strengthened or debunked.
When that methodology hits a wall, as seems to be the case with phenomenal experience, you either look for ways around it (which is basically the project of Philosophy of Mind), or start talking about in ways which imply there's nothing real to see here. Which is the tack Dennet takes.
