. . . Merleau-Ponty appreciates the essentially incorporated structure of perception in a way that Husserl does not. For Merleau-Ponty, that is, the body plays a constitutive role in experience precisely by grounding, making possible, and yet remaining peripheral in the horizons of our perceptual awareness: “my body is constantly perceived,” Merleau-Ponty writes, yet “it remains marginal to all my perceptions” (PP, 90). Again, the body is neither an internal subject nor a fully external object of experience. Moreover, as embodied perceivers, we do not typically understand ourselves as pure egos standing in a merely external relation to our bodies, for example by “having” or “owning” them, instead the body is itself already the concrete agent of all our perceptual acts (PP, 90–94). In perception, that is, we understand ourselves not as having but as being bodies."
. . . except in OBEs and NDEs. In the former, one's vision and consciousness are relocated outside, usually above, the body. This was undoubtedly the case in the spontaneous OBE I've described having when I was 21. But notably, it was not my 'egoic self' that seemed to take the outside perspective on my body, which remained facing toward the wall across the room. Undoubtedly all my prior experience in the world had been securely located from within my physically embodied immersion in the world. around me. During the OBE I was surprised but not concerned about my 'embodied and egoic existence' (rather, aloof from it), like the other consciousness I encountered later during the OBE when I overheard the thoughts it/she {I sensed it was a 'she'} was thinking.
It took me a long, (frankly frustrating) time to realize this contradiction in your approach to consciousness. That is, you would constantly refer me (in a corrective manner) to these philosophers who were clearly monists through and through, and in the next post, express an affinity for dualism. It was very confusing.
Regarding OBEs, the following showed up in my stream:
The Lessons of Out-of-Body Experiences
"Powerful, unnerving hallucinations show there’s something malleable about the way our brains construct our sense of self
About two months after his younger brother died of complications from HIV, Chris—a friend of mine in his 50s living in California—woke up early one morning. He got off the bed, stood up, stretched, turned around and got the fright of his life.
“The shock was electric,” Chris told me last year. “Because I was still lying in the bed sleeping, and it was very clearly me lying there sleeping, my first thought was that I had died.”
Of course, Chris hadn’t died. He was having what neuropsychologists call a doppelgänger experience: He found himself inhabiting an illusory body while his real, physical body was lying in bed. He says he’s not clear how long the feeling lasted. Eventually, “there was this enormous sucking sensation,” said Chris, making a long, drawn-out slurping sound. “I felt like I was dragged, almost thrown, back into the bed, smack into myself.” He woke up screaming. ...
Unnerving as they can be, out-of-body experiences, doppelgänger phenomena and other autoscopic hallucinations are probably our best window onto the way our brain constructs our sense of self, starting with the bodily self. Having a bodily self means several things. At its most fundamental, it anchors you in a body that feels like it is yours. You also feel that your body occupies a certain volume in physical space and that you are within that volume looking out with a perspective that feels like your own.
But as Chris’s experience shows, there are times—albeit rare—when we aren’t anchored in our physical body, suggesting that there is something malleable about the way our brains construct our bodily selves. ...
These experiments show us that, to create the bodily self, the brain has to integrate various sensations—such as touch, vision and many other types of internal and external information. There is no one place in the brain where this integration happens. Rather, researchers have identified a whole host of regions that are involved. The various illusions arise when the brain is fed conflicting information and tries to make the sense of it.
One can even fool the brain into embodying empty space. For example, in the rubber-hand illusion, if the experimenter takes the rubber hand away and instead moves the brush in the air in a manner suggestive of having a hand there while simultaneously stroking the hidden real hand, some people will soon start feeling touch in empty space. I can attest to this: I was taken aback by the weirdness of this illusion when I experienced it in Dr. Ehrsson’s lab.
But what these lab experiments and studies are showing us is that nothing is really leaving the body during an out-of-body experience. When the brain is operating on sensory information that is congruent (meaning that the sensations of touch match what the eyes are seeing, for example), the brain situates the self in the body and provides a sense of perspective and body ownership."
But when the sensations aren’t congruent, because someone is being tricked by the rubber-hand illusion or suffering from some neurological aberration, the brain does its best to make sense of all the misleading data. The brain can miscalculate the coordinates for the self, positioning it outside the body or in another illusory body.
There's a lot of literature about the sense of body self going awry in individuals:
The Man Who Saw His Double In The Mirror - Neuroskeptic
"During the previous 10 days, Mr. B. reported the presence of a stranger in his home who was located behind the mirror of the bathroom and strikingly shared his physical appearance. The stranger was a double of himself: he was the same size, had the same hair, body shape, and features, wore the same clothes, and acted the same way.
Mr. B. talked with this stranger and was puzzled because he knew much about him. Mr. B. even brought food to the mirror with cutlery for two persons. Eventually, the stranger became aggressive, and Mr. B.’s daughter decided to drive her father to the hospital.
…Mr. B. was well oriented and was perfectly able to recognize the members of his family."
We have really struggled to understand mental illness. However, it's clear that damage to the body-brain affects the mind.
I believe there are two causes of "mental illness." My belief is that consciousness/mind is information embodied by physical, biological processes in the body-brain. Consciousness/mind is essentially intentional information about the world (including the body itself). Said even simpler, consciousness is models of models of models...
When someone is suffering a mental illness 1) the physical substrate and thus physical processes embodying our models of the world are damaged, thus our models become damaged, and 2) sometimes the physical substrate/processes are fine and it's our models of the world (I'm ugly, I'm dumb, I'm a loser, etc.) that are damaged.
