It’s a classic science fiction trope, the old brain in a vat schtick.

You see it in H. P. Lovecraft’s weird fiction; the Matrix is actually a brain in a vat story with a twist–the whole body is in a vat, but only to keep the brain alive; then there’s classic Star Trek and the episode entitled, Spock’s Brain.

But the whole thing actually has its origin in modern philosophy. (Modern philosophy is its own horror story, you could say. It gave us Marx, among others. Would that his ideas has stayed in his brain the not found their way into the body politic.)

Some have identified Rene Descartes as our Dr. Frankenstein; but instead of inserting a brain in a body, he took yours out. When he said, “I think, therefore I am” he implied that your mind is the real you.

This is the origin of the mind-body problem. If you are essentially mind, how do you move your body? Is there something really, really sensitive that can detect fluctuations of thought and amplify them so you can move your arm? If so, why don’t we consider those fluctuations physical phenomena?

But Descartes was a particular sort of philosopher; he was what we call a, rationalist. You might think another school of thought, something called, empiricism, with its higher regard for sense data, would help. You would be wrong.

Empiricists believe that our minds are stimulated by our senses, but we are still sealed off in them. Is the sky truly blue, or is that just the way is appears to us given the faculties we have to perceive it with? We can’t really know, “the thing in itself”. We can only know how it appears to us, at least that’s the way the theory goes.

Since the seventeenth and eighteenth centuries we’ve made a little progress. We’ve situated the mind in a physical thing, the brain. But we still tend to think of our brains primarily as a place for the true you to live.

It’s not a big leap from this to brains in vats. If I really live in my brain, then perhaps it could be extracted from this body someday and either inhabit a virtual reality, like we see in the Matrix, or better still, maybe it could be placed in a new, upgraded body?

Help from a surprising source

We’re beginning to see that not only would this be technically difficult to pull off, you would no longer be you even if we could. And the people who are helping us to see this, believe it or not, are the people working on artificial intelligence.

The weekend edition of The Wall Street Journal, in a article entitled, Machines That Will Think and Feel, addressed the challenge of replacing people with robots. If you are going to have a robot who can understand humans and interact with them comfortably, then they must be made to feel, or at least have simulated feelings. And if they’re going to learn, they’ll need to actually be placed in human environments and learn by interacting with people.

To spell it out, robots will need bodies like ours to be intelligent social agents.

This isn’t in the article, but it occurred to me as I read it. What about empathy? Is it merely an algorithm, our do you truly need to feel pain to feel it? Let’s say we could upload consciousness onto a cyborg, and let’s say the cyborg even had sensors that simulated pain, would it be the same? Or would it be something different? I vote for different.

The resurrection of the body and the sacraments

I don’t think most Western Christians see the point of resurrecting our bodies. Heavenly spirits should suffice. If they think about it at all, they tend to think of it as trading in an old model, with things they’re not crazy about, for some new, sleek movie star or supermodel, model. It’s not even the same body transformed, its new from the bottom up.

It’s been noted by people smarter than me, that we suffer from a gnosticism problem in American Christianity. Harold Bloom in, The American Religion goes so far as to say genuine Christianity has never really taken root in the new world, it’s all gnosticism–everything from the Southern Baptist Convention to the Mormons. (He blamed it on John Wesley, actually since he likes gnosticism you could say he praises him for it.)

But gnosticism is the mind-body problem taken to the cosmic level. And I agree with Bloom, it’s very much at home in America, which is a reason something I call techno-gnosticism is growing in popularity. With the techno-gnostics the body isn’t really you; that’s why you can upgrade it forever, continually transferring the real you, your consciousness, time and time again. (I think it’s also a reason why Darwinism coexists so easily with New Age thinking. Who cares if our bodies emerged from a violent and seemingly random process, if your body is just temporary housing? That’s certainly the way Scientologists look at it.)

In conservative Protestant circles, those of us who lament the gnosticism in our churches denounce it frequently and loudly, but to seemingly little effect. Some of us have noted that there is an irony here–relying on disembodied reason to heal the rift between the mind and the body. And some of these people have commended a return to sacraments–making them the center of church life and worship.

But there is still a problem with this in my view, frequency in observance does not seem to heal the rift.

Another rift between the mind and the body

The division of labor has been with us for an awful long time, and it appears that it’s here to stay. Still, a good thing can go too far. And one division that I think bedevils all our attempts to heal the breach between the mind and the body is the division between work that is primarily mental and work that is primarily physical.

Any intelligent craftsman will tell you his materials and this tools speak to him. They inform his work and make him more intelligent. I think one of the most misleading things about plastic is the way it passes itself off as protean, only subject to human will.

When you actually work with real materials, with your hands especially, you come to see the native structure present in things. And these in turn shape your mind. They inform you.

Fewer people than ever work with the real world. And I’m afraid that robotics and artificial intelligence will utterly cut us off, at least economically. There will still be sex I suppose, but even sex may be robotized.

Back to my main point, in order to heal the breach, and even receive the grace to be found in the sacraments, we need to first return to the physical world and learn to listen to it again.
