physical, in your brain, which you are directly aware of that is this switching

aware of, and when it changes to green, this different physics has a greenness quality
you are also directly aware of?</span></p></div></div></blockquote><div><br></div><div>### Obviously conscious perception is a physical process but physics or awareness in my brain doesn't do anything "directly". There are probably hundreds of synapses involved in the basic calculation of reflectances (colors) in any small patch of the visual field, and the number of neurons involved in conscious, attentive perception of even the smallest sensory input is measured in the hundreds of millions if not billions. The qualities we talk about are features of large neural networks that are implemented in a complex physical substrate, and as I mentioned earlier, these are anything but simple or direct.</div><div><br></div><div>In case you wanted to ask if "redness" could exist independently of a physically functioning neural network, my answer would be "no". And as I mentioned earlier, every unique network that perceives changes in reflectance on strawberries will have its own unique "redness", incommensurate with qualia in other networks.</div></div></div>
