Diabetic retinopathy and poor eyesight. Typos ...
You haven't told me anything I didn't fully understand a long time ago.
There is this stuff we call Electromagnetic Energy.
View attachment 20450
There is a tiny little section of this energy spectrum we call "visible light".
This tiny part of the EM spectrum must have properties related to biological life and have unique abilities to excite cells that other parts of the spectrum do not have.
But all EM energy can do is excite a cell. It can't give the cell information. It can't tell the cell "I'm supposed to be turned into blue".
Blue is something a brain turns the stimulation of retinal cells into.
Blue only exists as an experience.
It is not a property of objects or of EM energy. It is a property of the brain.
It is not information, sight is a causal physical stimulus response to wavelength. The word we assign to a color is conceptual and cam be called information. And that leads to the mind body dichotomy. A prescientific metaphysical view that mind must separate from physical body, and brain. Thoughts and consciousness are not seemingly physical. You can not touch a thought therefore it must be immaterial.
