Strange that most are materialist when it comes to mind, but dualists in most other areas of life. E.g. capitalism is a dualist theory, that assumes humans have individual agency and thus property ownership. Our system of law is the same, assume people have agency so are responsible for their actions.
How would the legal system look if it was inspired by a materialist worldview? I'm not sure that it would change much from how it is set up currently.
I don't think the notion of a legal system makes sense within materialism. The idea of law is that there are universal rules that everyone is individually responsible for following, and are punished if they do not.
I thought quantam mechanics was enough doubt to refute the materialistic mind. A probabilistic system does not lead itself to a physical reduction of outcomes as follows from specific inputs.

If someone more knowledgeable about the subject would like to chime in, I would appreciate it.

I suspect that a key question is whether a probabilistic system is enough to bring agency into the picture. I can't be held (e.g. legally) responsible for my actions if they are the product of strict cause and effect processes. But it is also not clear if I can be held responsible for my actions if they arise from probabilistic mechanisms.
True. But agency is just how we rationalize responsibility being "fair", no?

The legal system is designed with "agency" in mind, but it's true purpose is to create law abiding citizens. We hold people responsible, because doing so alters behavior, mechanism of altered behavior is just window dressing.

> True. But agency is just how we rationalize responsibility being "fair", no?

I doubt this is a description many people would agree with - that agency doesn't exist but we just pretend it does so we feel better about locking people up to modify their behaviour. Aside from anything else, if we are probabilistic systems, we presumably can't actually do things like rationalise, or design things like legal systems. Similarly, I'm not sure it makes sense to talk about the legal system as having a goal if it is a (presumably slightly more complex) probabilistic system.

Of course, just as with materialism we can bite the bullet and accept that our typical descriptions of human life are strictly false and the real story is just a scaled up version of billiard balls knocking each other around (mutatis mutandis for the probabilistic picture). But if we want a picture that lets us keep some of our current view of human life, it is not clear that bringing probabilistic systems into the picture helps any.

> if we are probabilistic systems, we presumably can't actually do things like rationalise, or design things like legal systems.

Why not? Computers can reason and have constructed proofs. Probably a computer could construct legal arguments too. They might have some probability for errors (e.g. cosmic rays) that need to be accounted for and corrected, just like humans.

> But if we want a picture that lets us keep some of our current view of human life, it is not clear that bringing probabilistic systems into the picture helps any.

It might help people understand why people murder, or commit crime. Criminals might have errors that need to be corrected rather than focusing on a crime that needs to be punished.

Rationalising is a kind of ethical reasoning - constructing an account of something that shows it to be consistent with a wider body of ethical beliefs. So in your example, the idea of agency is a way of making the idea of responsibility mesh with our belief that things should be fair.

It is not clear to me that a computer can hold ethical beliefs, or that it would be troubled when some other beliefs are inconsistent with those beliefs and motivated to find a rationalisation that makes them compatible.

Materialism (of the mind) is just the notion that minds are the result of physical things (such as brains) doing physical things with physical information. QM has not invalidated that view any more than it has invalidated the view that stars or computers or the weather are the result of purely physical processes.
Interesting. Maybe it's because we can stand to be materialist about self, but less so about others? To be reductive about self is maybe humbling, but to be reductive of others would be unconducive to operating in the world with those others in "good faith" (whatever that is).

Just trying that thought on -- not sure i'll keep it, but thanks for provoking it :)

I am not sure who 'most' are, but whenever the issue comes up for discussion, dualism seems to be quite well represented, including in HN.

If I am not mistaken, you are assuming something along the lines that the physical world is deterministic, and this implies that materialism is incompatible with free will. Quite a few philosophers and scientists (perhaps a majority) are materialists who also are "compatibilists", thinking some form of free will is available within materialism. Here's Sean Carroll discussing it lightly [1], and Daniel Dennett has expounded in depth on the question.

Personally, I am not convinced that the free will of compatibilism much resembles the sort of free will as it is commonly imagined, but regardless, the apparent inconsistency that you outline here is not necessarily so, as an incompatibilist-deterministic-materialist can presumaby think that it was inevitable that we would organize society as if we had free will!

The article says materialism is the dominant view when it comes to the mind body problem.

It could be inevitable that once modern science is discovered, that 'free will' is a useful fiction that is disposed of for a more scientifically rigorous determinism. E.g. if we can identify that certain types of brains are most productive (high IQ), and other types of brains most inclined to criminal behavior, then we can modify human genes to produce the former kind of brains and not the latter.

In other words, if materialism is true, then the path forward is to figure out how to reduce the socially useful faculties to their material components, and recreate society through genetic engineering to have just the useful material components. Additionally, we would eliminate notions of property and responsibility as outdated, prescientific ideas.

Love to see eugenics proposed so nonchalantly.
It's the logical conclusion of materialism. If the conclusion is untenable, what does that say about materialism?
> capitalism is a dualist theory, that assumes humans have individual agency

If we don't have any sort of agency, then we have no choice but to believe whatever we believe, including dualism.

I think that most people experience agency, though, whether they actually understand it or not. Even animals do, unless you condition them not to like those learned helplessness experiments: https://en.wikipedia.org/wiki/Learned_helplessness

In that case, we just use propaganda and conditioning through our education system and commercial advertising to Skinner box train everyone to believe in materialism and that they are nothing but meat machines, and there is no higher purpose in life. Meanwhile, the scientists can figure out how to modify everyone's genetic code to eliminate all the deficiencies. Or, even better, invent artificial general intelligence, and unleash the singularity.
> scientists can figure out how to modify everyone's genetic code to eliminate all the deficiencies

That... might get really ugly if we ignore the social side of things. Even things like curing congenital deafness are controversial in certain communities.

Sure, don't ignore the social side of things. But, with enough propaganda and programming, and attracting everyone out of reclusive communities with fantastic products and lifestyles, then eventually we can gene edit our way to perfection with full acceptance from all.
> In the past, it seemed obvious that mind and matter were not the same stuff; the only question was whether they were connected. Everyone was a dualist.

This is a very western view. Many eastern religions and philosophies have, for thousands of years, expressed the unity of matter and consciousness (non-duality). Not only have they expressed it, but they developed exercises/practices to experience it.

This was the first thing that jumped out at me, that clearly this was written by a westerner for westerners. There are thousands of years of practice in non-dualistic investigations of mind. It always bothers me that someone could write an entire article on this subject, presumably doing research to undertake the task, and write a statement with such certainty that is false.
If we can ever move minds to different hardware, will dualism make a comeback?
Since the smallest particles of matter are indifferent, as far as we can tell (i.e. swapping one particle for another makes no difference in the physical state of the thing), then insofar as minds are individualized some kind of dualism is inescapable. This is because the mind must be at least an emergent phenomenon of some configuration, and the configuration is not affected by what particular particles make up the configuration.
I'm not an expert in the philosophy of mind, but I did just finish a class that spent a lot of time talking about the Churchlands. I figured I'd give my two cents in case someone might be curious as to weaknesses in their arguments.

The way the Churchlands' approach the mind is through reductive materialism. Basically they argue that the mind is identical to the brain given that brain process A causes mental/internal process B. With that reduction we should either eliminate language for mental experience or root it entirely in the corresponding physical process.

This sort of reduction is more or less a scientific reduction in that it serves an explanatory purpose. However, some philosophers reject the idea that scientific reduction is sufficient for a philosophical reduction which is something along the lines of brain process A completely explaining mental experience B. The problem that a philosophical reduction poses is that of internal experience.

Non-reductionists would argue that no amount of physical data could explain subjective experience. Brain scans can show what happens physiologically when you are happy, but not the 'what it's like to be happy'. Whether or not that's convincing to you is a matter of personal preference.

The bottom line seems to be that there is a major physical aspect to the mind, but also that we feel like we are more than chemical reactions. It is not clear that we can practically get rid of either dualism or materialism.

If you are curious, look at Thomas Nagel, and 'the hard problem of consciousness' by Chalmers.
