Ray Kurzweil Wonders, Can Machines Ever Have Souls?

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.'"

      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.

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.

The earliest references to a soul separate from the body are much earlier, 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.

    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.
