Klinko said> “The CLS is for Conscious Light not Physical Light (Photons). You must understand the difference between Conscious Light and Physical Light. If you keep talking about Photons and Retinas then you clearly do not understand what Conscious Light is. Conscious Light happens after the Retina and after all the Neural Processing that the Brain does. The Conscious Light is a product of the final Processing stage in the Visual Process. Conscious Light is a thing that happens in the Mind. Physical Light is a thing that happens out in the External World.”
TimB’s reply> So you’re saying that this thing we call “mind” has a projection screen in it (CLS) and anything and everything that we visualize is projected on to that screen. Is there also a homunculus in our “mind” who puts up and takes down the screen?
I think that the metaphor of a Screen is too belabored. When we visualize something, there is a pattern of neurological correlates firing off. That’s all. The neurons firing does not involve a screen. It is just neurons firing in a certain way, such that I “see” some facsimile of a tree.

All I’m saying is that it sure seems like some kind of Screen. Physicalists like to use the word Homunculus as a derogatory comment about the conscious Self. There sure is a Screen there as you can well see the next time you open your eyes and look. You so Blithely just say: “I See some facsimile of a tree” as if you think you know How it is that you See that tree.
Actually the CLS is not visible, since it is JUST a mental CONSTRUCT. It does not actually exist anywhere in reality, not even in my sinuses.
I like that Tim :-)
Which brings me back to Gould’s magisterium and his missing key.
The missing key is appreciating the fundamental “Magisteria of Physical Reality,” - and recognizing that both science and religion are products of the “Magisteria of Our Human Mindscape.”
Science seeks to objectively learn about our physical world, but we should still recognize all our understanding is embedded within and constrained by our brain’s mindscape.
Religion is all about the human mindscape itself, with its wonderful struggles, fears, spiritual undercurrents, needs and stories we create to give our live’s meaning and make it worth living, or at least bearable.
What’s the point? I think it’s about better appreciating our ‘frame of reference’ - and especially recognizing that we aren’t the center of creation.
W4U to the rescue again, I love the stuff you’re sharing. Here’s an appendix item.
