Anyway, here it is. Let me start with thanking Rick for sharing his notes. Furthermore, though I'm taking a non-agreeing viewpoint, please don't take my comments as disrespectful or seeking to end the conversation. In addition, I am not a physicist or biologist and don't think of my comments as being definitive. Rick shared from the Maturana conference.
Perception involves taking in data from the environment.
Light reflects off of the leaves of a tree and reaches my eyes. The eyes invert the image and send the inverted image through my optic nerve to my brain, and the brain registers things whereever it does that. I think it's really a tree, not a motion picture, or a drawing. We live and observe. I invite you to accept this question and consider it.
