Write-up2 (as at 19/04/2018 18:30:14): Brain
- There is a view that we are4 really, most fundamentally, our brains. It seems to promise some good things from both the “psychological criterion5” and “bodily criterion6” camps, since the brain is indeed part of the body7, and, in the absence of a soul8, the source of all our psychological functions. However, we seem to be much more than our brains. After all, who would want to be a BIV9 (Brain in a Vat)? According to Johnston (see "Johnston (Mark) - Human Beings"), BIVs are “maximally mutilated” human beings; which seems to be along the right lines. Note the important distinction between your surviving in a maximally mutilated state (as a brain) and you “really” being your brain.
- This is an issue Animalism10 has to contend with - whether a BIV is an animal. Paul Snowdon claims11 that no-one seems to think this, a view that Olson shares but on which he may be open to objection. He says that an animal with a prosthetic leg is a smaller animal with something non-animal attached. If this is admitted, don’t we end up with a sorites12 argument, that a BIV is a (very much) smaller animal; though not, I think, with any paradox?
- The big question is whether an animal’s brain is just another organ (like its liver) or whether it has some other status. That it is somehow special can be presupposed if we start conceptually with the brain as the core from which other parts are shaved off. Whether this is the right approach depends, I think, on what the brain does for the animal, and where the animal is on the phylogenetic tree. The brain is a much more important organ in some animals than others; in some lower animals it has no psychological functions and (maybe) its regulatory functions aren’t essential13.
- Why is the Woody Allen expostulation that his brain (in Sleeper) “(is) my second favourite organ” amusing? Firstly, of course, because of the sexual innuendo and the ultimately strange prioritisation (since you can’t enjoy sexual excitement without a brain), but also, I think, because your brain isn’t an organ that you “have”. Without your brain, there’s no “you” at all, or at least this is a strong intuition.
- You can obviously (given even today’s technology), do without a liver, and it seems that on a life-support machine your body can do without its brain – where the brain is looked upon merely as a regulator. But the reference of “you14” is a bit slippery in these contexts. There is a sense in which you as an organism can do without a brain – on life support – but “you” as an essentially psychological being cannot. The animalists claim that you – being identical to an animal – have no essential psychological predicates; yet it is difficult to resist the intuition that there’s a reference of “you” that does have essential psychological predicates. This is to you as a person15 – but the big question is whether this person is a separate substance constituted by16 the human animal, or is just a way of describing the animal when possessed of the appropriate psychological predicates. Saying that you can’t do without your brain is just another way of saying that your psychological predicates are those most important to you (the animal); those without which the other predicates cannot be enjoyed.
- The issue fundamentally concerns the integrity of organisms17. It is said that a brain isn’t an organism; but does an organism have to be self-supporting (the main reason for denying the status of organisms to disembodied brains)? After all, we seem to be allowing that an organism on life support is correctly described as an organism. We’ll discuss this further in its place.
- These issues are especially important when we consider various Thought Experiments18, in particular Brain Transplants19. Transplantation20 of all sorts seems to involve fusion21, with its logical problems for identity22 (not just for persons).
- Given that brains are important in lots of contexts related to personal identity, it is important to understand how they work – or at least to have some familiarity with some of what is known about how they work. Consequently, the reading lists below have some books on neuroscience. It is difficult to decide how the lists should be divided between this Note and that on the Brain Criterion23. As a first stab, the bulk appear under this Note, though some may be moved as I get further into the topic.
- I’ve tried to exclude from the lists items covered in other related notes, in particular:-
→ Brain Death25
→ Brain State Transfers26
→ Brain Transplants27

Footnote 11: Where?
- A number of my philosophical Notes are “promissory notes” currently only listing the books and papers (if any) I possess on the topic concerned.
- I’ve decided to add some text – whether by way of motivation, or something more substantive – for all these identified topics related to my Thesis.
- As I want to do this fairly quickly, the text may be confused or show surprising ignorance.
- The reader (if such exists) will have to bear with me, and display the principle of charity while this footnote exists.
- I need to check this.
- The idea is that in some lower animals, regulation is distributed throughout the body, with the brain playing a less central role.
- This is true of the octopus – a highly intelligent animal – with many neurones distributed throughout its tentacles.
- The same is also true (though to a lesser extent) of human animals – the PNS undertakes various co-ordinating functions, which is why brain-transplant TEs are somewhat simplistic.
- However, maybe I need to distinguish between different neural functions – regulation, coordination, sensation, etc.
- Frequently I’ll have made copious marginal annotations, and sometimes have written up a review-note.
- In the former case, I intend to transfer the annotations into electronic form as soon as I can find the time.
- In the latter case, I will have remarked on the fact against the citation, and will integrate the comments into this Note in due course.
- My intention is to incorporate into these Notes comments on material I’ve already read rather than engage with unread material at this stage.
- I may have read others in between updates of this Note – in which case they will be marked as such in the “References and Reading List” below.
- Papers or Books partially read have a rough %age based on the time spent versus the time expected.
