I'm inclined to disagree with that view.

A complete physical understanding of the structure and dynamics of the brain and all of its parts would never indicate some subjective experience of consciousness. We only assume that because we know from our own experience that consciousness exists (for ourselves).

Saying it's not a problem is hand wavy. Go touch a hot stovetop and tell me that consciousness does not have a quality and value all its own, beyond the electrochemical correlates of the experience of pain.

The hot stovetop is an interesting example to use, because the muscle-related reaction of your hand removing itself from the hot stovetop is often not a conscious act. But we do consciously perceive the sensation of pain.

In this very specific instance (and others like it) our consciousness might only be reacting to the world around us and comprehending the current state of ourselves and the immediate environment, as opposed to taking a conscious action.

It's the difference between watching audio waveforms on an oscilloscope and listening to Beethoven's Ninth Symphony. These are not equivalent experiences, no matter how accurately the oscilloscope reproduces the waveform.

I'd call it waxing poetic. How do you know if your senses and modeling is not actually getting the data for the symphony from advanced oscilloscope?

Good old brain-in-a-jar experiment applies.

Sensing pain is not a prerequisite for consciousness. We do not even know if having any senses is - though complete lack thereof will cause problems with detecting consciousness. Due to lack of response.

The intriguing part here is to consider if a person in a sensory deprivation apparatus is actually conscious.

Of course not, but pain is a prime and salient feature of conscious experience.

Also consider a person who is day-dreaming and one who is lucid dreaming. As with sensory deprivation, both may be having complex, self-aware cognition and remember it later to talk about it.

Something in causing you to say that you have subjective experience, however, and that's a causal relation that could theoretically be unraveled.

It seems unlikely that your statements have nothing to do with your consciousness, and you just happen to accidentally tell the truth.
