Mind/Brain and the idiocy of NPR

This is one of the worst NPR articles I've ever had the misfortune of listening to (and then reading again because I was so worked up). NPR "Science" article or listen to it here.
I was going to write out my thoughts but they are much too long. I'll just say two quick things:

First off, the mind/body problem is nonsense. There is no mind body problem, though for some reason most philosophers will tell you there is one. Most scientist will tell you there isn't and then proceed to give a nonsense answer about how there are only bodies. Newton killed the idea of the actual existence of physical bodies and no one has altered that empirical concept since: "a purely materialistic or mechanistic physics, impossible", he says. Not that I think you should just take his word for it; what he meant is that there's no proof a physical objects in light of action at a distance (what we now call the Theory of Fields and what he called Forces). This is again said by John Locke as "[god] annexed effects to motion which we can in no way conceive motion able to produce." (I'm almost positive that Locke didn't believe in God.) All this remains the case, there is no evidence for the existence of bodies -that is, of anything physical being ontologically substantive-. The Buddha and especially Nagarjuna's interpretation of the theory of emptiness, did the same much before either Newton or John Locke, but that is incidental.

For some reason one of the surgeons interviewed thinks this might amount to proof of God's Intelligent Design. What hogwash. This is just the argument from ignorance: basically it is an argument of this type (or so it was given in this NPR piece), if Evolution is correct then it should be able to explain complex systems. Evolution cannot explain complex systems, therefore Intelligent Design is true.
You see how the fact that Evolution is said, erroneously, not to be able to account for complex systems is in no way connected to the theory of Intelligent Design! That is, disproving one theory does not in itself provide support for any other theory. The logical form is If A then B, not B, therefore C. You can see that this mode of thought is fallacious.

"There is nothing about neurons that scientifically would lead you to infer consciousness from them. They're masses of gelatinous carbon and hydrogen and nitrogen and oxygen, just like other kinds of flesh. And why would flesh have first-person experience? So, even logically, it doesn't hang together."

Nonsense, there are plenty about neurons that would lead you to infer consciousness: this is as much nonsense as saying I wouldn't get tired if I walked up a hill because the hill doesn't have any substantive ontological status. But of course, that isn't even what the man is arguing... he is arguing that there is something special about PEOPLE that makes us different from all other things: that is a claim not born out by any facts. Understanding that bodies are not truly existing does not lead to the conclusion that what we call a body and what we call a mind are separable -they're not. They are dependently arising phenomenon; not real in themselves which arise only together: they are dependent, as in any subject/object relationship. That is again to say that just because bodies don't exist doesn't mean or imply anything about Intelligent Design or Evolution. And if these antievolutionists want to know something about how complex systems come about, they might look into Systems Biology or Complexity Theory.

The Evolution of Language and The BBC

Quentin Cooper's Material World is one of the two popular science radio programs which don't drive me crazy with an overabundance of vacuous questions. This weeks show was particularly good; He had an interesting piece on the significance of historical climate data in modern climate modeling, but the best part was the last segment on the Evolution of Language. I have to say that I'm in love with linguistics, especially biolinguistics, as it solves so many interesting intellectual problems. Mark Pagel and Nick Chater were the guests on Material World and had quite interesting things to say about the coevolution of language biologically and sociologically: really, quite remarkable. I recommend a listen. They, Mark and Nick, casually mention another smart Linguist by the name of Steven Pinker, and if you haven't check him out on TED then you should watch him now. They of course talked about a hero of mine, Noam Chomsky: I say of course because he invented modern linguistics but he unfortunately doesn't do TED talks; you can, however, check him out on Google Video very easily as most of his talks are publicly posted.

Indispensable Cooking

The Economist, that bastion of so many insensibly sensible people, had an interesting recent article about someone whose work think I rather like: Harvard Professor, Dr. Richard Wragham. I'm not totally convinced by his arguments but I do find them interesting, rigorous, and plausible. Among other things, Dr Wragham helped develop the idea that non-human animals often use non-foods to self-medicate: (in the technical literature this is called Zoopharmacognosy.) This latest article is concerned with the evolutionary role of cooking in human animals (erectus & sapian) and is based off the work published in his 2003 paper, "Cooking as a Biological Trait" and a 2006 book on the same subject (The Cooking Enigma). The paper is not unreadable and "suggest that cooking may be obligatory for humans" because of calorie needs which are satisfied by the increased efficiency of digestion from cooked food. I'm not really sure if this explains my need for a good curry or a home-cooked Pizza, but at least I now have good reason to not be a Raw Foods person.

Mutual Aid

The November Scientific Fundamentalist has an interesting article by Satoshi Kanzawa about his Savanna Principle: the article argues that the recent Psychological work, done by Ilja van Beest and Kipling D. Williams, amount to demonstrative proof in support of his principle. The Savanna Principle is a thesis, as with all mechanical models involved in describing evolutionary thought; however it does seem to have a good amount of support -including this new work (done out at Pardue University in evolutionary psychology). While Kanzawa takes this Psyc study, called "When inclusion costs and ostracism pays, ostracism still hurts," as further proof of his thesis, I have to pause a moment: Williams and Beest work notwithstanding (and its factual implications for the Savanna Principle), it seems like intellectual honesty might incline Kanzawa (not to mention anyone working in the field of evolutionary psychology) to refer interested readers to Peter Kropotkin, who argued for the intrinsic biological nature of people which inclines them toward mutual aid and social cooperation: "Sociability is as much a law of nature as mutual struggle... mutual aid is as much a law of animal life as mutual struggle." This is of course from his 1902 book called Mutual Aid: a factor in evolution. Kropotkin I think is to this day one of the most interesting reads concerning these topics because his arguments are so engaging; not to mention full of his historical analysis which supports his thesis just as well then, 106 years ago, as any manner of modern experiments I've read: (admittedly, that might not amount to all that much.)
