Science & Tech
With the unprecedented rise of millennial computing, lightning fast telecommunication, vibrant social media and virtually limitless access to information, our lives are consumed by a torrent of powerful technological influences.
The gap between who we are at a deeper, more philosophical level and who we appear to be on our various web profiles is simultaneously widened and blurred by recent scientific and technological advancements. “Who we are” has become a vexing and tiresomely complex concept, and in our push toward increasingly more efficient modes of survival, we seem to have run out of collective patience with it.
Yet in spite of this, debates over what makes us who we are continue today. The age-old question of how our minds interact with our bodies has been passed off from philosophers to computer scientists and engineers. Some of the latter figures claim that the advent of robotics and more sophisticated computing methods has made inevitable what Google engineering director Ray Kurzweil refers to as our “next stage of evolution”— by which he means artificial intelligence. A.I. is, in simplified terms, a rapidly accelerating field that tries replicating human functions and capabilities in machines to the fullest extent that current technology allows.
But is it possible for machines to exhibit complete human intelligence and consciousness?
UC Santa Barbara Psychology professor Stan Klein, whose research focuses on issues related to social knowledge representation, said that mainstream psychology believes that humans are machines, and thus can be understood from principles that comprise the backbone of modern applications in machine technology.
“The materialist dogma of modern science threatens to remove the [mind-body] issue from discussion, since it does not fit their metaphysical presumptions,” Klein said. “Perhaps they are right — or perhaps one can intelligently widen the scope of physicalism to encompass experience.”
At the forefront of such “physicalist” groups today are neuroscientists, many of whom believe that the mind can be fully reduced to electrochemical and mechanical bodily functions. From this perspective, replicating human consciousness in machines may prove less difficult than expected.
This possibility once pondered only in science fiction thrillers (in which the robots typically end up rebelling against their creators and destroying humanity) is becoming more compelling with the integration of technology and automation into nearly every facet of our lives, and may even become perfectly natural.
But is it scientifically feasible?
Albert Shin, a UC Santa Barbara Philosophy doctorate alumni and visiting assistant professor at Villanova University, said that even if we can explain the various workings of the brain, we are still missing something in our explanation of day-to-day conscious experience.
“With recent developments in cognitive and neuroscience, it is easy to think that all there is to the mind is a collection of brain cells,” Shin said. “Admittedly, the evidence suggests that there is a much closer relationship between mind and body than was argued by dualists like Descartes. But it would be a mistake to jump to the conclusion that all there is to the mind is simply matter.”
How these debates will pan out is still yet to be determined. But in proceeding, we should not forget to keep asking ourselves two basic questions. Who are we? And to what extent can — or more aptly, should — we allow science to answer that question for us?
