I grew up with robots. Of course they were on the television screen and I was far away in rural-ish western Pennsylvania. They were exotic creatures built by guys much more intelligent than I could ever hope to be, and they were powerful, completely rational, and scary. Now I find myself involved with the FIRST Robotics team in my daughter’s high school where kids a third my age are building a robot. It is a humbling experience.

The more I ponder my small support role in the construction of a robotic creature, the more my thoughts turn to George Dyson’s masterful science writing in one of my favorite books — Darwin Among the Machines: the Evolution of Global Intelligence. I would not have known of this brilliant book had I not met George and a group of his friends several years back while they were discussing some of the ideas raised in his work. The main one that captured my attention was the premise that when we build machines we may be constructing an unrecognized form of consciousness. The greatest minds in neuroscience today cannot agree on what consciousness really is or how far it extends beyond this “three-pound universe” in our heads. Although most would decline to comment on the overtly religious term “soul,” we still know that any difference between consciousness, mind, psyche, and soul is very slim indeed.

Read this book!

Our lifestyle is made possible by robots. We drive cars largely constructed by them, use their chips to communicate over vast distances, and even take a stroll on the surface of Mars with them. My question from Monday’s post may have been whimsical, but it was serious. Where is it that the essence of a creature resides? Does it require carbon-based biology, or do we, unwittingly, create a race of slaves just like the gods of old?

In the Heart or in the Head?

I don’t have cable television. I don’t even have one of those digital conversion boxes. I’m afraid the costs and technology have gone beyond a guy who grew up with a black-and-white television with the screen the size of an old Mac Classic. I still try to keep a wary finger on the pulse of popular culture, and fortunately the internet provides just about everything in a condensed version. When I want to see a television show I generally do so through DVDs. Again, expense is prohibitive to the underemployed, but kindly family members often help out with occasional contributions. My brother surprised me this Christmas with the first season of the History Channel’s Monster Quest series (brothers sometimes see what you try to hide from the wider world). After a long weekend of class prep, I sat down to watch an episode last night that introduced me for the first time to the work of Dr. Robert J. White, a retired professor from Case Western Reserve University.

I have always been intrigued by the unlimited possibilities, no matter how remote, that science fiction can conjure. This episode, however, was factual and showed footage of Dr. White’s successful head transplant operations on monkeys in the 1970s. I had no idea that such work had ever really been conducted, let alone successfully. Visions from X-Files: I Want to Believe flashed across my cerebrum while I watched the footage. Not to mention the ubiquitous heads-in-jars of many a science-fiction movie! A plaguing religious question was also stirred back into life after having settled at the bottom of the tank for many years – where does the essence of a person reside? Organ transplants are everyday occurrences, and many lives are prolonged by the sharing of body parts no longer used by their original owners. And transplants do not stop below the neck – cornea transplants bring us very close to the brain, the presumed seat of our personality, consciousness, or, if you will, soul.

when a head meets a body

Dr. White’s monkeys that survived seemed to have retained the personality of the original monkey head on its new body, but I wonder if that was just an illusion. In our world where each individual is treated as a discreet unit, the essence of a person is thought to reside in the brain. Our brains, however, recognize our bodies and sometimes bodies reject the very organs intended to save them. Is there really any possibility of preserving the essence in one’s head alone? Or are we, like ants and bees and Portuguese Men o’ War, really all part of a collective organism? Maybe there is a good reason I don’t have cable or a digital conversion box.
