Regular, reasonable person here.

> Your body is your mind and your mind is your body. Full stop.

This is completely unwarranted judging from the rest of your post ("in the very infancy", "nearly completely unknown", "mostly in the dark", "haven't the foggiest idea"; although I appreciate the frankness).

If people made bold statements like "There is no such thing as X" in any other field at a similar stage of development, their claims would be rightly dismissed as pseudoscience. ("There is no such thing as a graviton. Full stop.")

Your claim is not a finding of your field of expertise, or any other branch of science. It's metaphysical belief. You're entitled to it. It's a widely shared belief. It might be a belief with a lot going for it. Metaphysical claims are fun! They can be discussed! But I wish people wouldn't confuse them with scientific knowledge.

I gather that there are two (somewhat related) definitions of mind-body duality:

1. mental phenomena are not physical

2. the mind and body are distinct and separable

Neither of these claims are supported by modern science in any meaningful way. It is perfectly reasonable to say that mind-body duality has been disproven by science, insofar as it is reasonable to say anything has been disproven by science. Just because neuroscience is still in its infancy doesn't mean there can be no established foundations of the discipline. These foundations may turn out to be wrong or incomplete, but that doesn't mean we shouldn't talk about them.

Would you say there’s a gut/body duality then? Or a fascia/body duality? Understanding of the gut and fascia are also in their infancy. We barely knew anything about the gut microbiome until a decade or two ago. Up until about a decade and a half ago, when doctors dissected cadavers, they simply threw out the fascia. Now we know it’s got more nerve endings than the eyes.

We’re in the infancy of understanding the human body, period. But why does that imply a mind/body duality? One thing that’s clear is that everything is interconnected, and I think that much is clear from the comment.

The whole idea of a mind/body duality is a historical artifact. If someone wants to argue that there is a duality, then I think the onus is on them to prove it exists, not the other way around.

I took it as them dispelling the notion of metaphysical nonsense, not unlike how space and time are talked about as spacetime.

Not that it matters all that much. Every single test ever performed looking for a mind absent a body has conclusively, and unquestioningly failed. There are even large bounties available for showing a single successful test which have yet to be claimed.
