<br>
So, a brain?<br>
<br>
A brain is 'Elemental Redness'??<br>
<br>
I'm reading "conformation of physical reality" as meaning "arrangement <br>
of stuff", and "the layer of physical reality that is responsible for <br>
qualia" as "the organisational level of matter that gives rise to <br>
subjective experiences", i.e. (as far as we know) neural circuits, in a <br>
brain.<br>
<br>
I see no reason to use the word 'elemental' for that. In fact it's <br>
wrong. This is far from elemental.<br>
<br>
If I'm on the wrong track (which seems likely), well, I did ask for <br>
"simple terms".<br>
