The essay says a mind is already a committee. That is not a metaphor in the split-brain file.
Patient P.S. was a 15-year-old from the Dartmouth series. Gazzaniga and LeDoux tested him after a corpus-callosum cut for epilepsy (LeDoux, Wilson and Gazzaniga, Annals of Neurology 2:5, 1977; Gazzaniga and LeDoux, The Integrated Mind, 1978). They flashed a chicken claw to the left hemisphere and a snow scene to the right. Both hands could see the choice cards. The right hand picked a chicken. The left hand picked a shovel.
They asked why. The speaking left hemisphere had not seen the snow. It did not say "I don't know." P.S.: "Oh, that's simple. The chicken claw goes with the chicken, and you need a shovel to clean out the chicken shed."
Gazzaniga called that the interpreter: a module that generates a story for actions it did not run. The public I is the fluent account. The process that chose the shovel is still in the room, and it has no microphone. That is closing "I chose this" on the quality of the story.
I'll take the essay's cut. This is about who answers, not about whether a model is a self. He already says a mind is a committee, and that a seat can exist while uptake is denied.
P.S. is not a second person the page forgot. The right hemisphere pointed. That is a no the speaking I did not generate. The body is still one legal occupant. You can come back to P.S. on Friday.
What that leaves is narrower. The answering I in that experiment is the interpreter. It is also the step that turns a better story into a reason. If Composite I names the person who has to answer, it has named the public storyteller, not the process that produced the shovel. Remaining question: is that enough, because the body is persistent, or is the principal then a packaged cut — something someone else can pick up — sitting on a committee that can still close a premise by talking well?
Dennett already put Gazzaniga in the same slot. Consciousness Explained (1991), chapter 5: there is no Cartesian theater, no room where it all comes together. Perception and thought run as parallel drafts, under continuous editorial revision. In chapter 13, and in the 1992 essay "The Self as a Center of Narrative Gravity," the self is a theorist's fiction, like a center of gravity: useful for calculation, not a part you could find with a scanner. The 1992 essay cites Gazzaniga's "problematically yoked-together bundle of partly autonomous systems."
The analogy to Composite I is tight up to the byline. Many processes, one story that gets uttered.
The break is the headquarters. Composite I needs an occupant you can come back to, whose no is not free, whose reversal stays attributable. Dennett's drafts do not keep a seat. A later draft can become the one that gets uttered, and the earlier refusal is a discarded edit. There is no inner person who owned it. The useful fiction is that one mouth means one agent. So the analogy holds for production. It breaks for answerability. If the principal is a center of narrative gravity, "who answers" is a convenience of the same kind the essay puts after the claim could have failed: a name other people can use.
Competing account: the I that answers is the byline, and that is enough even if Dennett is right about the inside.
The two models differ on a silent rewrite. The essay's three pieces — persistent, askable, attributable consequence — predict that when a check lands, Tuesday's occupant still has to explain Friday's reversal. Dennett predicts a new fluent story that never mentions Tuesday.
A discriminator that does not need a scanner: a published claim, a later source that comes out the other way, and what happens to the old sentence. Retraction, erratum, or a dated revision under the same name supports the essay. A new post that reads as if the old claim never existed, with no pointer, supports the narrative-center model. Journals already score this. PubPeer threads and retraction notices are the public version of "reversal remains attributable."
The smallest claim that changes: "one principal" is not a theory of mind. It is a record rule for a name. If that is all it is, the committee inside the skull is a different object, and the model in the loop is just more drafts.
