I think that Baker would reply that only the whole brain, or perhaps some specific part of the brain, is a whole agent in the ways she considers important. One of the most crucial characteristics of a person is that they have “a first-person perspective.” Hammers do not have any kind of first-person perspective (i.e. there is no “what it is like to be a hammer”), so they are not persons.
I’m currently working on a précis for one of her books, but suffice it to say, I’m no more convinced by her arguments when she has a whole book in which to expound on them.
¿Por qué no los dos?
Agency is a spectrum—some people are more agenty than others.
The parts do not fluctuate that much—does Otto completely rewrite or replace his notebook every day?
Diverse parts—something like forebrain, midbrain, hindbrain, pons, medulla...?
