Ray Kurzweil Wonders, Can Machines Ever Have Souls? 630
Celery writes "There's an interview with Ray Kurzweil on silicon.com talking up the prospects of gene therapy as a means to reverse human aging, discussing different approaches to developing artificial intelligence, and giving his take on whether super intelligent machines could ever have souls.
From the interview: 'The soul is a synonym for consciousness ... and if we were to consider where consciousness comes from we would have to consider it an emerging property. Brain science is instructive there as we look inside the brain, and we've now looked at it in exquisite detail, you don't see anything that can be identified as a soul — there's just a lot of neurons and they're complicated but there's no consciousness to be seen. Therefore it's an emerging property of a very complex system that can reflect on itself. And if you were to create a system that had similar properties, similar level of complexity it would therefore have the same emerging property.'"

The earliest references to a soul separate from the body are much earlier [wikipedia.org], and there are also views of the soul which do not necessarily view it as distinct from the body (which certainly is the sense in which Kurzweil interpreted the question, whether it is how the questioner intended it or not) which also predate Plato, and there are many ideas of souls in religion that, whether or not they predate Plato's discussion, are clearly independent of it.

You've tossed the baby out with the bathwater in your list of where consciousness is not. It's clear from observation that consciousness exists in interaction between the nervous system and the world around it (and also the nervous system and the rest of the material of the body). It is an emergent property. Subjectively consciousness is unitary although this may not in fact be the case- there are multiple systems of consciousness (vision, hearing, haptic, cognition, etc). The works of James J. Gibson and Edward Reed- among others- are worth checking out in this regard.
The conceptual difficulty comes from the popular notions of "soul" present in various mythologies, especially the notion of an immortal soul that is somehow placed into the body at some point and which leaves the body at some point. The existence of this soul is non-demonstrable and its existence is an article of faith not observation; it becomes problematic when faith attempts to trump observable reality.
Interestingly the Buddhist conception of human functioning avoids these difficulties. It denies the existence of an immortal individual soul and identifies all aspects of existence as mutually emergent properties which are conditional, constantly changing and ultimately temporary. Over-simplistically, Buddhism proposes six types of consciousness: sight, hearing, touching, tasting, smelling and mental formations. Each arises as an interaction between the properties of the organism and the properties of its environment. No permanent, immortal and highly problematic soul (which violates the laws of physics) is needed.

In Buddhism, all things are said to be ephemeral -- which is just a fancy word meaning temporary. Even the soul is ephemeral. The concept of 'ephemeralness' (is that a word?) is central to Buddhism because Buddhism teaches that one should not become attached to things because all things are ephemeral. That's why life is so much suffering in the world -- suffering stems from attachment.
Anyway, to simplify the soul concept greatly: if you think of the ocean and you pull out a glass of water from the ocean, the water in the glass is what Buddhists call 'the soul'. When the glass breaks (death), then the water merges back to the ocean. That specific volume of water is no longer identifiable again -- if you were to dip another (or even the same) glass into the ocean, you'd get a different soul, because you'd have a separate distinct volume of water.

In the same manner, if you take very simple AI's of today, you can have them recognize "How are you today?" and respond accordingly, but their limited responses will also make a pretty poor representation.
Increase the pixel count or the complexity of the AI though, and it starts to become a better *representation*. The apple looks more realistic. Eventually photo realistic. The AI becomes smarter. Eventually it can pass a Turing test. HOWEVER, in both cases, they are simply high refined representations/emulations of an object. No matter how detailed the picture of the apple becomes, it never becomes a real apple.

http://tal.forum2.org/hofstadter_interview [forum2.org]
Scientist and inventor Ray Kurzweil presents a different take at immortality, a more physical one. Like you, Kurzweil views the soul as "software" that can be executed on different "hardware". He further believes that in a relatively short while, we will have electronic hardware which is the equivalent of the human brain (which you eloquently characterize as a "universal machine", capable as "executing" any "soul software"). Once such hardware is available, Kurzweil believes immortality would have been reached: by "downloading" our soul-software onto electronic brains ("Giant Electronic Brains"?), we will become immortals, able to create backups of our souls to be restored in case of disaster, and able to shift our physical location anywhere in the speed of a software download.
Do you share Kurzweil's view of hardware being able to execute human soul software within the foreseeable future? Do you agree with his view of this being the equivalent of immortality â" will the software running on the electronic brain be the same "I"?
I think Ray Kurzweil is terrified by his own mortality and deeply longs to avoid death. I understand this obsession of his and am even somehow touched by its ferocious intensity, but I think it badly distorts his vision. As I see it, Kurzweil's desperate hopes seriously cloud his scientific objectivity.
I think Kurzweil sees technology as progressing so deterministically fast (Moore's Law, etc.) that inevitably, within a few decades, hardware will be so fast and nanotechnology so advanced that things unbelievable to us now will be easily doable. A key element in this whole vision is that no one will need to understand the mind or brain in order to copy a particular human's mind with perfect accuracy, because trillions of tiny "nanobots" will swarm through the bloodstream in the human brain and will report back all the "wiring details" of that particular brain, which at that point constitute a very complex table of data that can be fed into a universal computer program that executes neuron-firings, and presto - that individual's mind has been reinstantiated in an electronic medium. (This vision is quite reminiscent of the scenario painted in my piece "A Conversation with Einstein's Brain" toward the end of The Mind's I, actually, with the only difference being that there is no computer processing anything - it's all done in the pages of a huge book, with a human being playing the role of the processor.)
Rather ironically, this vision totally bypasses the need for cognitive science or AI, because all one needs is the detailed wiring plan of a brain and then it's a piece of cake to copy the brain in other media. And thus, says Kurzweil, we will have achieved immortal souls that live on (and potentially forever) in superfast computational hardware - and Kurzweil sees this happening so soon that he is banking on his own brain being thus "uploaded" into superfast hardware and hence he expects (or at least he loudly proclaims that he expects) to become literally immortal - and not in the way Chopin is quasi-immortal, with just little shards of his soul remaining, but with his whole soul preserved forever.
Well, the problem is that a soul by itself would go crazy; it has to live in a vastly complex world, and it has to cohabit that world with many other souls, commingling with them just as we do here on earth. To be sure, Kurzweil sees those things as no problem, either - we'll have virtual worlds galore, "up there" in Cyberheaven, and of course there will be souls by the barrelful all running on the same hardware. And Kurzweil sees the new software souls as intermingling in all sorts of unanticipated and unimaginable ways.
Well, to me, this "glorious" new world would be the end of humanity as we know it. If such a vision comes to pass, it certainly would spell the end of human life. Once again, I don't want to be there if such a vision should ever come to pass. But I doubt that it will come to pass for a very long time. How long? I just don't know. Centuries, at least. But I don't know. I'm not a futurologist in the least. But Kurzweil is far more "optimistic" (i.e., depressingly pessimistic, from my perspective) about the pace at which all these world-shaking changes will take place.
In any case, the vision that Kurzweil offers (and other very smart people offer it too, such as Hans Moravec, Vernor Vinge, perhaps Marvin Minsky, and many others - usually people who strike me as being overgrown teen-age sci-fi addicts, I have to say) is repugnant to me. On the surface it may sound very idealistic and utopian, but deep down I find it extremely selfish and greedy. "Me, me, me!" is how it sounds to me - "I want to live forever!" But who knows? I don't even like thinking about this nutty technology-glorifying scenario, now usually called "The Singularity" (also called by some "The Rapture of the Nerds" â" a great phrase!) - it just gives me the creeps.

looks like a three step process? (Score:5, Insightful)
Historically, the way we've discovered what part of the brain does what first is by running into someone with an abnormal part of their brain. The visual cortex, hippocampus, etc. So far though, no one has shown up that lacks consciousness.
Now I suppose that would be by a lot of definitions "brain dead", since consciousness is akin to being awake or dreaming, but still we haven't ran into someone that for example, had a brain tumor or took a nailgun to the head that hit a key area that put their lights out for good, on a consistent basis for that area of the brain.
Now not every location in the brain is highly localized. For example, the area of the motor cortex that controls speech is known, roughly, but it varies slightly from person to person. It's likely that consciousness is a highly distributed function of the brain. That's going to make it a lot harder to study.
I think the whole idea of referring to consciousness as an "emergent property" boils down to our not understanding what causes it, multiplied by it seeming to require a highly complex system to support in the first place.
100 years ago if you'd have presented a mathematician with a laptop with Mathematica loaded on it, he'd probably consider it sentient.
My personal take on it is that consciousness is the brain constantly considering a myriad of possibilities, trying to determine their outcome/impact, in an effort to shape future events in a desirable way by adjusting our actions to try to achieve those outcomes. This is a brute force search, and requires the insanely massive parallelism the brain is designed for. Until we can build a system capable of parallelism on that level, we will not have a "conscious" machine. Everything else before that is a fake, trying to cheat that basic requirement by using shortcuts through linear processing. Simple organisms we don't consider sentient behave exactly as we'd expect a linear system to, directly reacting in a predictable way to provided stimulus, with no ability to learn. Learning is the process of tweaking the values used to consider past events, in order to alter present behavior, to achieve a more desirable outcome in the future. Learning and consciousness go hand in hand.
You can see the middleground in a lot of less complex animals. Give a reasonably advanced animal a tool and a reward achievable by proper use of the tool, and they will play with the tool, experimenting with different way to use it until they get lucky and get the reward. Then it quickly becomes easier and easier for them because they've learned to use the tool. That's the "considering the possibilities" done live and with the tool, which may be most of what people consider "thinking" or "consciousness". I believe what "separates us from them" is that we can do this consideration without having the tool in hand. We can imagine future use of the tool and work out in advance what we need to do with it, or to at least select the proper tool in advance. If you give a monkey a toolbox full of tools it may take them some time experimenting to figure out which tool is the right one to loosen the screw to open the box with the banana in it. Maybe this "imagination" is a third ingredient?
Even after we get the parallelism problem solved, there's the matter of the wiring. Evolution has lead brains to be preprogramed to do both the learning and the consideration, and that may turn out to be a tough system to figure out and duplicate. Or it may be pathetically simple. Best guess here is we will get parallelism figured out, then learning, and the last hurdle will be the imagination behavior.

5000 year old debate makes news ... again ... (Score:5, Interesting)
People have been asking this since the first little girl asked her daddy if their Dog Spot has a soul. I offer you this reader:
A father and a mother each have a soul. They have a child. Start you debate here.
If the soul is bestowed upon the child by a divine being, then the divine being may just as likely bestow a garbage can or a tree a soul at it's (the divine being in charge) discretion. So there is no restriction on a robot having a soul. From a Christian perspective, if God knows when even a sparrow falls then I'd wager he'd be on top of giving any robot that askes for a soul one with due haste. If God is the father that makes HAL God's grandkid.
If the soul is emergent, inherit in the child and develops as does conciousness then it is just as likely a soul would eventually emerge for any complex system. The universe itself may have a soul due to its complexity.
Once you have a given rule on the source of the soul then you can spend another lifetime debating what a soul is. As far as the original discussion though we come to the same answer every time:
From a spiritual aspect, where God can do anything and the soul is crafted by God, it can be bestowed upon anything at God's discretion thus a robot with a soul is not only probable, but would more then likely be expected.
From a scientific standpoint, there is no restriction on conciousness and self awareness by a mechanical or electronic system. As our brain, as complex as it is, is an organic machine. So from a scientific standpoint there doesn't appear to be a restriction on a soul in an robot or computer. This does though imply that there is a good chance your hamburger had a soul depending on it's level of awareness. Which then leads into the discussion of what level of sentience\awareness endows a person with a soul which then leads into a whole mess of crap ranging from animal right, abortion, and in the event of intelligent non-human life, the discussion of Sentient Rights (as human rights would be racist at that point.)

Rather obvious. In addition, it is not known whether consciousness is actually a property of the brain, or whether the brain is merely an interface device for something else. The oncludsion that consciousness is a property of the brain is non-scientific. The current established fact is that we have no clue at all, besides the sensors being attached to the brain are in part also available to the consciousness. In addition we know that while there seems to be genuine "free will", most people rarely use it and are generally emotion driven (animals have emotions too, so nothing special there) and do not even use interlectual capabilities that seem to be at least in part a feature of the brain. Quite frankly, seeing the how a lot of people behave, I would not be surprised to find out they actually do not have a consciousness at all or at least that it was not in control most of the time...

If the consciousness is not in the brain, but instead somewhere else, how is it that consciousness is affected by drugs? Drugs can alter the subjective experience of consciousness quite dramatically. Yet they're nothing but mundane organic chemicals which fuck with brain chemistry. That, to me, is extremely strong evidence that consciousness is resident in the brain.
If 'I' were a supernatural entity resident elsewhere - a 'soul' using the brain as an interface to the physical world - then I might expect drugs to slow down transmissions from the brain, or even scramble them to some extent. So reflex delays, loss of coordination, even hallucination, that's possible. But the core 'I', the consciousness, should be serenely unaffected by this.
Anybody who has done something bloody stupid while drunk knows that this is not what brain-affecting drugs are like. The consciousness itself as a subjective experience is strongly affected by chemicals which affect the brain.

Consciousness is a brain function. (Score:3, Insightful)
Consciousness is a brain function, and there is consciousness center in the brain. Has it ever happened to you to wake up but not be conscious for a brief moment in time? it has happened to a friend of mine: he woke up, got to the kitchen, started breakfast, but he was not conscious at the time. His wife talked to him, he replied...suddenly, he woke up, and realized he was in the kitchen. He did not remember how he got there.
This incident, and others I've heard and read, makes me believe that consciousness is a brain function. In the above case, this function was not activated at waking up time, but much later, but the person acted as usual.
I think the purpose of the consciousness function, regarding evolution, is to place the entity in the universe; the advantages of this higher function for evolution are obvious: if one realizes his/her/its place in the cosmos, it can act on a higher level to preserve his/her/its presence in it. The clear evidence for this is humans: they are dominating the planet as we speak.

Assumption: For there to be a soul, it has to be located somewhere.
So we can try to figure out where it is by ruling out the places where it isn't.
It can't be in the body surrounding the brain. We can currently replace any part of it without making a human "soulless" according to a religious authority. I've never heard a priest declare somebody with a leg prothesis to lack a soul, for instance. So it's not in the leg, arm, heart, veins, liver, kidneys, etc. There have been humans with artificial replacements for all of those, but I've never heard for anybody to claim they lacked a soul because of it. Surely if the soul disappeared with the disappearance of a body part it'd make some noticeable difference.
So a place left: the brain. However there are cases of humans who managed to retain quite normal functioning with a hemisphere missing, and AFAIK either half can be missing. The resulting human won't be completely normal to be sure, but I still haven't heard of anybody referring as somebody with half a brain as lacking a soul.
Two conclusions may be made from this.
The first one is that since that the lack of no part of the human body seems to cause a "soulless" condition, there's no such thing.
The second one is that the soul is integrated into the brain over all its area, so having a brain means having "half a soul". In that case, how much soul is needed? Does having any brain damage imply you have "less soul" and are therefore less human? Also brain size and weight changes with age. Does that mean that a child has less soul than an adult? And the decrease in mass with age would imply having less of it as you get older. That would also imply that a machine using a part of a human brain would automatically acquire the amount of the soul present in it.
So it seems to me that either there's no such thing, or a machine can be made with it easily.
The other option is to suppose the soul isn't attached anywhere, and not implicit in a human body, but external and granted by a deity. In which case the answer would be "yes", since an all-powerful deity could always attach one to a robot if it felt like it.
