You... disagree? Do you mean your own intuition is different, or do you mean you have some special insight into my psychology that tells you that I'm misunderstanding or misrepresenting my own intuitions?

I mean my intuition is different.

I don't feel that mental states are simple! Yet the Mary hunch persists. You seem to be hopping back and forth between the explanations 'qualia seem irreducible because we don't know enough about them yet' and 'qualia seem irreducible because we don't realize how complicated they are'.

Alright, I'll try to stop hopping and nail down what I'm saying:

1. I think the most likely reason that qualia seem irreducible is because of some kind of software problem in the brain that makes it extremely difficult, if not impossible, for us to translate the sort of "experiential knowledge" found in the unconscious "black box" parts of the brain into the sort of verbal, propositional knowledge that we can communicate to other people by language. The high complexity of our minds probably compounds the difficulty even further.

2. I think this problem goes both ways. So even if we could get some kind of AI to translate the knowledge into verbal statements for us, it would be impossible, or very difficult, for anything resembling a normal human to gain "experiential knowledge" just by reading the verbal statements.

3. In addition to making qualia seem irreducible, this phenomenon explains other things, such as the fact that many activities are easier to learn to do by experience.

I've never actually read any Denett, except for short summaries of some of his criticisms written by other people. One person who has influenced me a lot is Thomas Sowell, who frequently argues that the most important knowledge is implicit and extremely difficult, if not impossible, to articulate into verbal form. He does this in terms of economics, but when I started reading about the ineffability of qualia I immediately began to think "This probably has a similar explanation."
