Well, this is the problem with our society as a whole. In particular, and most importantly, the problem with intellectuals. They tend to gloss over the inexplicable things like consciousness and the mind. It's just too hairy and scary to try to tackle and try to understand. I think that's why we've distanced ourselves, ironically, from ourselves for so long.
We need to really take a long look at ourselves and try to understand what's going in our mind.
Modeling and measuring are different from genesis. Where is the mind? Should we even be asking "where"? What about "why"? Can we even ask that? Do we even know which questions make sense to ask about the mind? Maybe we can't use language to talk about it. After all language seems(again we have no real empirical basis for this) deeply coupled with the mind so we're going to use the mind to understand the mind? It's microscopes all the way down then I guess.
It is mystical simply because most people haven't really shed much light on it. So the mind remains a mystery. The mind just really, truly does not make sense. It baffles philosophers, scientists, biologists, lay people, etc. We'd rather tackle something like the inner-workings of quarks or the interactions of black holes with dark matter than even attempt to answer the question: what is even allowing me to communicate with myself and answer any of these other questions? Why do I think?
We can talk about personalities. We can talk about the brain. We can talk about language. But how do we work backward from those attributes of the mind to get to the point of genesis; where is the mouse in the wheel creating the thoughts writing this sentence.
No one knows. We don't kinda know. We, truly, have no fucking clue. We think it's related to the brain. That's it.
I don't take it as a personal attack because honestly our understanding is mystical nonsense.
