@Fil Albuquerque,
Old boring and sterile thinking again.
1) Classic materialism has been gone for a loooong time, since the demise of positivism in the end 19th-early 20th century. Keep it up.
2) The fact that something (object A) emerges from something else (object B), does not mean that object A is less important than object B, or somewhat disminished.
Life as a phenomenum emerges from inanimated matter. And yet life is much more interesting and complex and fascinating than inanimated matter. Only a positivist -- a reductionist, a narrow-minded materialist, see point 1 above -- would think like you do, that physics are more important than biology because the latter emerged from the former... Modern scientists see it the other way round: what's more complex is always more interesting than what's more simple, and the emerging stuff cannot be reduced to the stuff it emerged from. It has a life of its own, rules of its own, goals of its own.
A rat wants to live, although none of the atoms that it's temporarilly made of care about living. You can't understand the rat by studying its atoms, not anymore than you can understand Shakespeare by studying how paper and ink are manufactured.
Likewise, the fact that the mind emerges from the brain says nothing about the mind being an illusion, or being unimportant. In fact, our brain consumes something like one fifth of our energy intake, while it only represent 2% of our total weight. It supposedly does so, so that it can make the mind work... Thereofore our mind is important enough, biologically, that we allocate a totally disproportionate share of our resources to it.
