I have to disagree. Water has properties that are not predictable from the properties of hydrogen and oxygen. Living things have properties that are not predictible from the properties of its constituent elements. There is quite a bit of mystery to be unraveled, but no reason to resort to magic. There is no reason to assume anything other than emergent properties.
The first reason for not making the assumption of supernatural activity is that there is no evidence for it. The second reason is that neuroscience is flourishing without it.
The radio receiver anology would have to assume that all animals that have brains also have souls, since there is no jarring discontinuity between the behavior of animal brains and the behavior of human brains. My college training is in special education. If you take the whole spectrum of human differences and capabilities, there is a pretty seamless transition with apes. There is not much you can say about the difference between the human mind and the mind of apes that applies to all humans.
It seems you do recognize there is something going on in biological systems which is more than the physical laws can address but that you are also confident that whatever it is must be corporeal, i.e. exist in space/time.
That is somewhat different from my view.
Whereas I can see an as yet undiscovered field-like host for the will to live which is common among all living things (amoeba, bacteria, whales, viruses, man, etc.) --- I also see that something more than that is required to explain the unique willfulness of man, in particular individual man. (my post 582)
For Lurkers - in Physics, a "field" exists at all points of space/time.
That unique willfulness of man is the non-corporeal, non-spatial, non-temporal - spirit or soul. In Scripture it would be ruach and neshama - a sense of good and evil, right and wrong, altruism and selfishness, etc. as well as a yearning or sense of belonging "beyond" space/time. In Scriptural parlance, "ears to hear".
The field-like host to consciousness would be nephesh in Scriptural parlance.
