Returning from our deeper thread to your original comment, can you classify the nature of your objection to this point? For example, would you posit that there is nothing we would classify as mental phenomena that is not already addressed by other methods? If so, that seems fine to be because it reflects our uncertainty about the mental rather than a disagreement with this line of reasoning where we suppose there to be some things we might naively describe as mental, whatever the resolution of our uncertainty about the mental will later tell us, if anything.
