OK, children, it's time to stop squabbling and go get some cookies and milk! Be nice, now!
In response to you, Helix, and ignoring your sarcasm about ghosts being what I would try to push off on you, all I have to say is that intelligence itself is not physical. Evidence? Here --
Roger Lewin, "Is Your Brain Really Necessary,"
Science, Dec. 12,1980, p. 1232.
"'There's a young student at this university," says Lorber, 'who has an IQ of 126, has gained a first-class honors degree in mathematics, and is socially completely normal. And yet the boy has virtually no brain.' The student's physician at the university noticed that the youth had a slightly larger than normal head, and so referred him to Lorber, simply out of interest. 'When we did a brain scan on him,' Lorber recalls, 'we saw that instead of the normal 4.5-centimeter thickness of brain tissue between the ventricles and the cortical surface, there was just a thin layer of mantle measuring a millimeter or so. His cranium is filled mainly with cerebrospinal fluid."
