No. Of course not but thank you for the comment. It is a valid objection. I should have been more precise. My “left arm” example and case of the head transplant probably muddled this point. The mereological fallacy is not about physical wholeness of body. It only applies in the case of the mind/body problem and arguably only in conscious beings. It is limited to describing the disconnect/logical impossibility of attributing specific acts of consciousness to only the/a brain and not to a person/conscious being as a whole. A “whole” person in this case might be armless or legless for example but they would still be recognized as a “person” and of no lesser or greater value than any other. The mereological fallacy applies to the limbless person as much as the “normal” limbed. At exactly what point of disembodiment is the line to be drawn is a very interesting and difficult question. I certainly don’t pretend to have the answer but I think the case of possible head transplantation is instructive to think about. Thanks again for reading and commenting!
