I'm not referring to phenomenological philosophy but rather 1st person report, subjective experience, psychology, etc.
Of course when someone reports having experience x, we still don't know for sure that they are... however, science that incorporates such 1st person reports strongly indicates an exclusive nexus between the mind and brain. No other locus of the body shares the relationship that the mind and brain do.
Phenomenology (psychology) - Wikipedia
"The question is about
numerical identity. To say that this and that are
numerically identical is to say that they are one and the same: one thing rather than two. This is different from qualitative
identity. Things are qualitatively identical when they are exactly similar." Google
Much of the discussion
@smcder and I have been having over the past year or two involves point 4. Perhaps review our discussions and the articles we've looked at?
MBP: what is the relation between the mind and body? They seem connected but we can't see how that might be.
Points 1-4: mind and body are the same thing, they just seem like two different things due to the reflexive, inferential nature of a mind perceiving itself.
