The novelist and philosopher R. Scott Bakker recently put out a mind blowing essay on the philosophy of extraterrestrials, which isn’t as Area 51 as such a topic might seem at first blush. After all, Voltaire covered the topic of aliens, but if a Frenchman is still a little too playful for your philosophical tastes , recall that Kant thought the topic of extraterrestrial intelligence important to cover extensively as well, and you can’t get much more full of dull seriousness than the man from Koeningsberg.
So let’s take an earnest look at Bakker’s alien philosophy…well, not just yet. Before I begin it’s necessary to lay out a very basic version of the philosophical perspective Bakker is coming from, for in a way his real goal is to use some of our common intuitions regarding humanoid aliens as a way of putting flesh on the bones of two often misunderstood and not (at least among philosophers) widely held philosophical positions- eliminativism and Blind Brain Theory, both of which, to my lights at least, could be consumed under one version of the ominous and cool sounding, philosophy of Dark Phenomenology. Though once you get a handle of on dark phenomenology it won’t seem all that ominous, and if it’s cool, it’s not the type of cool that James Dean or the Fonz before season 5 would have recognized.
Eliminativism, if I understand it, is the full recognition of the fact that perhaps all our notions about human mental life are suspect in so far as they have not been given a full scientific explanation. In a sense, then, eliminativism is merely an extension of the materialization (some would call it dis-enchantment) that has been going on since the scientific revolution.
Most of us no longer believe in angels, demons or fairies, not to mention quasi-scientific ideas that have ultimately proven to be empty of content like the ether or phlogiston. Yet in those areas where science has yet to reach, especially areas that concern human thinking and emotion, we continue to cling to what strict eliminativists believe are likely to be proved similar fictions, a form of myth that can range from categories of mental disease without much empirical substance to more philosophical and religiously determined beliefs such as those in free will, intentionality and the self.
I think Bakker is attracted to eliminativism because it allows us to cut the gordian knot of problems that have remained unresolved since the beginning of Western philosophy itself. Problems built around assumptions which seem to be increasingly brought into question in light of our increasing knowledge of the actual workings of the human brain rather than our mere introspection regarding the nature of mental life. Indeed, a kind of subset of eliminativism in the form Blind Brain Theory essentially consists in the acknowledgement that the brain was designed for a certain kind of blindness by evolution.
What was not necessary for survival has been made largely invisible to the brain without great effort to see what has not been revealed. Philosophy’s mistake from the standpoint of a proponent of Blind Brain Theory has always been to try to shed light upon this darkness from introspection alone- a Sisyphean tasks in which the philosopher if not made ridiculous becomes hopelessly lost in the dark labyrinth of the human imagination. In contrast an actually achievable role for philosophy would be to define the boundary of the unknown until the science necessary to study this realm has matured enough for its’ investigations to begin.
The problem becomes what can one possibly add to the philosophical discourse once one has taken an eliminativists/Blind Brain position? Enter the aliens, for Bakker manages to make a very reasonable argument that we can use both to give us a plausible picture of what the mental life and philosophy of intelligent “humanoid” aliens might look like.
In terms of understanding the minds of aliens eliminativism and Blind Brain Theory are like addendums to evolutionary psychology. An understanding of the perceptual limitations of our aliens- not just mental limitations, but limitations brought about by conditions of time and space should allow us to make reasonable guesses about not only the philosophical questions, but the philosophical errors likely to be made by our intelligent aliens.
In a way the application of eliminativism and BBT to intelligent aliens put me in mind of Isaac Asimov’s short story Nightfall in which a world bathed in perpetual light is destroyed when it succumbs to the fall of night. There it is not the evolved limitations of the senses that prevent Asimov’s “aliens” from perceiving darkness but their being on a planet that orbits two suns and keep them bathed in an unending day.
I certainly agree with Bakker that there is something pregnant and extremely useful in both eliminativism and Blind Brain Theory, though perhaps not so much it terms of understanding the possibility space of “alien intelligence” as in understanding our own intelligence and the way it has unfolded and developed over time and has been embedded in a particular spatio-temporal order we have only recently gained the power to see beyond.
Nevertheless, I think there are limitations to the model. After all, it isn’t even clear the extent to which the kinds of philosophical problems that capture the attention of intelligence are the same even across our own species. How are we to explain the differences in the primary questions that obsess, say, Western versus Chinese philosophy? Surely, something beyond neurobiology and spatial-temporal location is necessary to understand the the development of human philosophy in its various schools and cultural guises including how a discourse has unfolded historically and the degree to which it has been supported by the powers and techniques to secure the survival of some question/perspective over long stretches of time.
There is another way in which the use of eliminativism or Blind Brain Theory might lead us astray when it come to thinking about alien intelligence- it just isn’t weird enough.When the story of the development of not just human intelligence, but especially our technological/scientific civilization is told in full detail it seems so contingent as to be quite unlikely to repeat itself. The big question I think to ask is what are the possible alternative paths to intelligence of a human degree or greater and to technological civilization like or more advanced than our own. These, of course, are questions for speculative philosophy and fiction that can be scientifically informed in some way, but are very unlikely to be scientifically answered. And if if we could discover the very distant technological artifacts of another technological civilization as the new Milner/Hawking project hopes there remains no way to reverse engineer our way to understand the lost “philosophical” questions that would have once obsessed the biological “seeds” of such a civilization.
Then again, we might at least come up with some well founded theories though not from direct contact or investigation of alien intelligence itself. Our studies of biology are already leading to alternative understanding of the way intelligence can be embeded say with the amazing cephalopods. As our capacity from biological engineering increases we will be able make models of, map alternative histories for, and even create alternative forms of living intelligence. Indeed, our current development of artificial intelligence is like an enormous applied experiment in an alternative form of intelligence to our own.
What we might hope is that such alternative forms of intelligence not only allow us to glimpse the limits of our own perception and pattern making, but might even allow us to peer into something deeper and more enchanted and mystical beyond. We might hope even more deeply that in the far future something of the existential questions that have obsessed us will still be there like fossils in our posthuman progeny.
