Blood Pumping Mechanism of the Hoof (2020)

Speaking as a horse, I wonder why you think we have any ideas at all. But anyway, ideas are less complex than the systems that they explain, that's the whole point of ideas. We're always progressing to simpler explanations while at the same time discovering that the world has new complexities. (The simplification is winning.)

I'd go into more detail, but I've seen a white gatepost and have to stop now.

> Is it possible even in principle for a conscious entity to have an instinctual understanding and awareness of every low-level detail comprising its design?

Access is possible, complexity limits what you can do with it.

It's like having a JTAG port on a chip with a lot of test access. You can read the state of most of the gates, but now you're overwhelmed with data. Processing that data takes more resources than the system being monitored.

At a larger scale, though, this starts to work. Modern industrial plants and cars have sensors all over the place, more than are really needed to operate the system. They're there to diagnose it.

I’ve thought about this. Or at least something like that.

When reading dune there’s a class of women who can control their biochemistry in such a way that they can eg prolong lifespan, or anything else within the realm of feasible biochemistry.

Here I was like: how does the nervous system function in that way? How could signals from the mind control the behavior of molecules?

The mind cannot itself feel pain, similarly the mind has sensory limits within the body. As argued in a book called the body a guide for occupants: cancer is a very good example of a disease that our nervous system should be able to detect but for whatever reason we don’t, probably because cancer is something we can only now treat.

Not all of the body can be made legible to the mind.

Although maybe a better question: why don’t we have a dedicated organ that can sample blood with laboratory like precision and make anomalies available to the conscious mind beyond whatever faculties we currently have?

PS

One thing that definitely should be within the realm of conscious control: body fat. There are ways of forcing the body to metabolize more fat for energy and the biggest problem is managing excess heart (easily becomes lethal). But this could be super useful in cold climates. Imagine being able to literally burn body fat to stay warm? The amount of heat that can be released is enormous. Nowadays most of us could probably afford the otherwise superfluous expenditure of body fat (beyond essential functions).

Many of the systems that complex biological systems rely on, evolved long before the brain, some of them go back to before there were nervous systems at all. Truth is that it's all a hodge-podge of layers of complexity built on-top and sideways. In tech terms we would call it enormous technical debt.

It's difficult to say anything about experiential/first-person consciousness as we don't know what it is. Some say it doesn't exist and everybody is a p-zombie. That aside...

As you mention, there's a problem where if you want to know yourself fully - including observability of your mind - you need to be aware of the thing that is aware, and aware of the thing that is aware of the thing that is aware, etc, down to infinite regress.

But that doesn't necessarily mean that it's impossible. It would suggest that such a being works by moving along a set of fixed point. Suppose x is the state of the physical mind (whether that's a brain, a set of chips, or something else). Suppose f(x) returns the updated state after this mind takes into account what it knows (i.e. f(first-order aware) = first- and second-order aware). Then if the mind-state always changes so that x is a fixed point of f, then the mind already knows all there is to know about itself.

So the question, on the mind side, is whether there exists a sufficiently generally intelligent type of mind for which moving along fixed points is computationally easy. I don't know. It could be possible, it could be impossible. Finding fixed points is hard in general, though.

There's also the problem of sensors, which may seem simpler but hides a similar difficulty. What happens if whatever thing that measures blood sugar fails? Or if the immune system goes auto-immune due to an immune cell defect that makes it report benign cells as foreign? Then you need an integrity sensor for the sensors - then you need an integrity sensor for the integrity sensor... At least this fixed-point problem for sensors should be easier than the one for general minds.

The consciousness:complexity ratio would probably express itself in that a mind of a certain complexity with the fixed-point-of-f constraint would be less intelligent on average than a mind of the same complexity without such a constraint.

I think considering yourself as a consciousness inhabiting a body, maybe in a way similar to the aliens in The War of the Worlds, is a false premise. Consciousness is one control system, but there are many, and your mind relies not just on the brain but the entire body.

So when you say being aware of every detail of your design, that hinges on awareness in the realm of critical thinking - but all the while, parts of your body are absolutely aware and in control of every little detail. I'd even say, these "subsystems" send a notification to your consciousness if anything is outside normal operational parameters, which makes total sense: Surfacing only details that require immediate attention is a good strategy to control complex systems, and one that we apply to many superficial constructions as well.

Another fun aspect of this is that when you try to suffocate yourself by holding your breath for too long, you'll pass out. Why does that happen? Because your body switches off your rogue consciousness in an attempt to stay alive - because staying alive overrules your subjective experience.

If you try to understand by knowing every little detail it is bound to fail because that attempt only increases the number of things you need to understand.

I think the Buddhist had it right in this instance, if you want to understand yourself completely stop trying to know every little thing and just be aware.

There is a Sci-Fi novel about fancy forest frogs, which possess that ability down to the biomolecular level. And a human researcher stranded on their world, being modifyied by them, to help her survive and adapt to the toxic environment.

Humans are kept alive by quadrillions of closed control loops. Being aware of them all would be very distracting.

> "A horse is an extremely sophisticated biological machine, but it has no idea what makes itself tick."

To my ears, a lot of detail is hidden in "knowing what makes itself tick". The limit of human Umwelt, cognitive closure, is an arena I find fascinating.

Modern people tend to identify understanding with mechanistic explanations. Veins, glycogen, immune states, hoof pumps. These are interesting and satisfying to us. But does that kind of explanation satisfy only because we are apes with ape language and interests, leaving aside even that we live in a society that values those explanations?

If a horse-level intelligence existed, perhaps its most satisfying explanations would not be "I can inspect the venous plexus in my hoof," but something else. Maybe more proprioceptive: pressure, load, gait. Or maybe that's just still my primate prejudice poking through.

What would satisfy a horse scientists might seem opaque or insufficient to us, but maybe our biochemical account would seem equally beside the point to it?

Maybe there is no species-neutral answer to what counts as understanding what one is.

On a deeper level, I suspect that a "complete understanding" in an absolute or divine sense is infinite. Our perceptions are necessarily limited, only a model of reality. In order to understand in a way that helps us survive, we must filter out a lot of information that is not absolutely irrelevant, but is irrelevant to us. Even Funes remembered only that which is relevant to a human, that which he could perceive in the first place. He could not remember changes in magnetic fields, background radiation, subtle shifts in gravity.

I guess when the horse lays down the pumping force from the heart is enough to pump the blood back. Much less gravity to work against
