TSQ, although you may very well be right... absolutes bother me a little... our knowledge is ever growing, and what may be considered preposterous today, may be in the school textbooks tomorrow... here's an example I love: In the late 1700's, the French Academy of Sciences looked into the matter, and proceeded to declare that stones could not fall from the sky, because there were no stones in the sky. And that was the end of the matter for some time. Nevermind that people had actually seen them fall with their own eyes. Now, meteorites are undisputed. The rational inquiry, although extremely logical and useful, I think can become self defeating when it falls into arrogance. We do not know everything, currently.
Absolutes bother me too, but that documentary was basing its whole premis in an absolute and definite statement: the heart is more than just a pump. I thought the self-delusion of the host so obvious that it was sad and painful to watch; he went in with a conclusion and then tried to make the evidence support it, when it didn't. The scientist would do a demonstration and the host would enthusiastically say, "So what you're saying is
this!" Then the scientist would say, "Well...
kind of..." and then we'd cut to the host saying, "Clearly, the science shows...!"
In this case, the reasoning is deeply flawed. Aspects of his hypothesis I think are really valid and important to discuss. He talks about the false dichotomy that separates mind and body, and that is a very real false dichotomy with a lot of serious implications. The implications apply strongly to this very thread, and are likely much of the reason for the shame that
Nesat is feeling. I know it was for me. When it is deeply ingrained in your culture that the mind is different from the body, and that sickness of the mind is your fault rather than the fault of a germ, it's hard not to feel ashamed, even when you know it's not true.
Anyway, the documentary's entire argument for the heart being not simply a pump is based in the idea that it is too beautiful to be a pump. It's the same as looking at a bunch of children's finger paintings and then being presented with the Mona Lisa and saying, "Clearly this isn't a painting, it is too beautiful to be a painting!" He tries to make the science support this idea, specifically in the segment discussing DeVinci, where they show that DeVinci, using a glass model, discovered the suction action of the heart. The host then lays a picture of DaVinci's diagrams side by side with diagrams of 19th century machinery and says that they are clearly not the same thing -- he seemed to think he'd demonstrated that the heart wasn't a pump, when really all he'd shown was that it is a beautiful, sophisticated, and complex pump that utilizes suction. Every single conclusion he drew was a non sequitur.
The documentary then proceeded to make a big deal of the neuronal network of the heart, and that's as it should be. The fact that the heart has an independent network of neurons is really fascinating, and shows that the relationship between the heart and brain is more complex than previously thought. But that neuronal network helps to control the heartbeat, there is no evidence, or real plausibility of mechanism for how it could generate emotions or thought. Yes, the heart has a neuronal network, but so does the digestive tract.
Finally, there was the really offensive line about how people who employ reason are "cold" and "mechanical as the machines" they were comparing to human body function.
I know the host was genuine, when he spoke of his wife I really felt for him, but none of what he was saying actually makes any sense.
