The soul brain relationship is a paradox (ho ho ho my current fave topic). Well, the soul is not that brain, because each part of the brain (individually) is not the soul. Just as the wheel is not the bicycle. The wheel is part of the bicycle. Because the soul is an emergent feature, it is (a, b, c, d....x, y, z) all together. "soul" is a novel property the parts do not have individually.
If we look at say at part q, and ask "is q the soul?" then the answer is no.
But it is also the soul, in a sense, ie in the sense that the wheel is the bicycle, and if you damage the wheel you damege the bike.
And if you damage a,b c brain part, you damage the soul also. They are the soul, but just like a,b c are letters rather than the alphabet. ANd "soul" is more alphabet than letter, if that makes sense?
Hence the parts are something like tokens of the whole, but not identical to it either. We only have a finite view, piece by piece, rather than the unquantised whole as it exists independent of spectatorship of its bits. The bird singing in to forest makes a sound (and the brain is conscious), but when we listen we only access an aspect of it (x,y z sound waves from the sound cone (here, I am imagining something like a
light cone, but made of sound waves. Perception is of the part, this or that aspect of the sounds emmitted, not of the whole of it).
Similarly "the soul" is the
brain cone, insofar as it interacts with itself in the space time continuum. yet / however / but we see only ever see bits of it (this that or the other scan, neural imaging, this or that neuron etc etc).
We do not listen to or see consciousness (or "the soul"), we
are consciousness (or "the soul").
But its aspects are open to us in part. We are the alphabet, but only ever hear and see the letters. Yet the hidden whole is something like the most obvious thing!
