That something isn't known does not (and I doubt that I have ever said otherwise) automatically mean the supernatural is where it stems from. Science doesn't know where the mind stems from and would probably not come knocking on the door of the supernatural for an answer. "Don't know" is simply "don't know".
Science does "know" where mind comes from - it's from the brain. What Science doesn't know is
how mind comes from brain - if, indeed, that be a meaningful distinction. You're argument relies on the mind being a seperate and independent entity from the physical development of the body; the only candidate for that is a supernatural soul.
Pure Scientism-speak here and later. And only Scientism-adherents (who form a minority in the world) make such statements. When empiricism can be shown - empirically - to be the best or only way to know anything about everything (and I mean in ALL areas of human activity) then we can review the actuality behind this Statement of Faith.
There's no Scientism in my statement at all. We do have a lot of empirical evidence for mind being a product of brain; Chiroptera details some in his post. We know activity in the brain both reflects and affects mental states; we can watch emotional responses in the brain, pin down areas related to memory, speech and vision, we can see how damage to the brain impaires mental process and the inbibing of drugs produces emotional and mental states and artefacts. These things are well established. Dualism, meanwhile, has never come up with decent answers to philosophical questions posed 350 years ago let alone the ones posed by modern science.
If you're referring to my later statement. Please, give me a single counter-example.
Just because you believe something, even heartfeltly MJ, it doesn't mean it's true.
Well slap me with a kipper and call me Sally.
