> but I find it difficult to imagine how a material thing, the brain with its neurons and electric impulses and neurotransmiters, can be able to generate what philosophers of mind call qualia, which is something apparently non material.

There was a time when people said the same thing about the body. How can a slab of muscle and bones move? What is moving the body? Of course, it has to be a soul. The same thing with the heavens. Look at those magnificent planets and stars. Certainly gods must reside there and are moving them.

> I have an experience. How my brain/hardware causes the experience? Is the experience material? Perhaps. I wonder: how? e.g.: when I see a cup, where in my brain is the subjective experience of the cup? Is it coded as electric impulses? What decodes it and translates the impulses to qualia?

This is basic philosophy questions. It can't be answered by philosophy. It has to be answered by science ( neuroscience ).

Honestly, philosophically pondering about the brain/mind right now is akin to pondering about the gods/planets a few hundred years ago. Or philosophizing about where the soul reside in our body ( pineal gland? heart? liver? )

Now, we see how absurd those assumptions were because we advanced scientifically and we gained knowledge. I'm fairly certain the same will happen with the mind/brain questions.

All I know is that there is no "qualia" without the brain. Applying occam's razor, why do we need the mind? Other than as a crutch for our lack of understanding of the brain?

Movement, electric impulses, nerves, are observable/measurable stuff. I'm not sure that your example is analogous to qualia. You suppose that qualia is material. It may be, still I find it very hard to imagine how it could be. What is our subjective experience made of? How electricity and neurotransmitters cause subjective experience? It appears that there's a gap between objects and qualia because only I can see my qualia, while everybody can see a brain or measure electric impulses.

Anyway, I like your hypothesis that it could be answered by science. It can lead to interesting experiments and theories.

That could be true. Or it could be true that you don't really exist and the subjective experience is an illusion. The subjective self seems to be just another iteration of the unique soul. The soul is what makes you you and the soul is why you experience things.

It's the only way we can settle things one way or the other. We can argue about gods on mount olympus til the cows come home. The only real way to be sure is to actually climb the mountain and see for ourselves.

My inclination at the moment is the mind is fiction. We no more have a "mind"( aka brain's soul ) than plants which move to capture more sunlight have a "mind".

We just have to patiently wait for science to advance to answer the mind/brain questions. In the meantime, it is fun to philosophize about it.
