My prompt is now closed, but I will now freely answer questions backed by me twenty-five years of reading books on neuroscience and Mahayana Buddhism (with some Indian and Tibetan philosophy woven within).
My research began with my martial arts habit. Remember, Chinese martial arts points to the story of kung-fu being brought to Shaolin by Bodhidharma, a "historical" figure that Zen groups often look to as the "first patriarch." So, in this cultural soup, physical exercises and spiritual endeavors go hand in hand. However, in modern clubs and gyms, physicalism and the art of making a buck has forced a divorce between these two deep cultural forces.
This response is built upon two patterns. One is ancient and one is modern. I will consider the latter first. Beginning in the 90s, neuroscience began mapping out how the "I" narrator is developed in the brain. The regions known as the medial prefrontal complex, posterior cingulate cortex, and the inferior parietal lobule are the ingredients of our Default Mode Network (our narrator). So, the idea that the body is the "I" or that thoughts are identical to the "I" have been updated. Many will not be aware of this if they do not read about this matter. Indeed, most people live out their lives not knowing exactly what the "I" represents.
Furthermore, Mahayana's
Diamond Sutra began this question long, long ago. Throughout its text, as you can see in my quotation, the question is if there are any beings to be liberated. Many garden-variety Buddhists have no idea about this sutra, so it is often quite a surprise to suddenly stumble upon it. So, the problem these two experiences (Neuroscience and Mahayana Buddhism) point out is the problem of how a basic physicalist suddenly discovers that the notion of an "I" is and has been in question.
In closing, as we martial artists might remember, the Japanese art of Kyudo via Zen utilizes the idea of letting go of the I-narrator in order to make a bullseye. In fact, the target is the Self ("I" is not rooted in the brain any longer, which points to Zen's nondualist bones). If we widen this process, we will see that the narrator is great as a type of behavior-management system in Darwin's playground, however, when we double down on its material existence outside of its DMN essence, we lose the plot. Remember, Donald Hoffman and his team of mathematicians ran one-thousand or more evolutionary simulations in a quest to find out if humans evolved to "see the truth." The answer: No. We evolved to see food sources, sources of water, and habitation. According to their experiments, we have a 0% chance of seeing reality-as-is. Our occipital lobe feeds us a 3d map to the best of its ability. However, as the Kyudo archer might tell us: Don't confuse the map for the terrain.
Now, do I care if people reject these findings and stick to physicalism? No, that is their prerogative. It will not bother me in the slightest.
Do I care if the entire population rejects even the example of Kyudo and Zen? No, that is the prerogative of each DMN.
Have a superb Saturday, sir!
