Free Will

[Yoo]

Maybe cut to the right heart next time  I said this: " I also can't think of any possible function they might fulfil, that wouldn't be already fulfilled by the machinery in the brain that caused them."
Every function you just mentioned, comes ultimately from the brain. Why add the qualia? That was my question.

-as does qualia......but, cut that out, if you wish to refer to the machinery as a separate thing.... then lets do that.

Seen any machines enjoy a candy bar lately?  Ever seen a machine give a girl a box of chocolates to get in her pants?  Have you ever seen a machine form an emoptinal bond with a family so strong that it would lay down it's own life for them?  When's the last time a machine invented a moon lander?  Did machines evolve from a vulnerable species with a need to know whether or not something out there would eat them..did machines evolve with a necessarry aversion to being eaten?  When's the last time a machine invented a language or painted a work of art?

The machinery of the brain -does- do all of these things... qualia is -also- the machinery of the brain.  Might there be some other way to do them, or some other machine that could do them.  Maybe, not yet, not here anyway.  This is how we do them.  These are their many functions.

First of all, I was talking about a function in the evolutionary sense. So painting a work of art or inventing a moon lander isn't precisely what I was thinking of, hehe. 
Secondly, I've never understood how people could make sense of the idea that qualia are, literally, brain activity. "They don't come from brain activity, they are brain activity." That has never made sense to me. Could you explain it?
