Here’s an essay I have written for a compilation of essays to be published in 2014 entitled Turborealism, following an exhibition with the same title curated by Victoria Ivanova and Agnieszka Pindera at Izolyatsia, Donetsk, Ukraine.
BATS, DOGS, AND POSTHUMANS
What is it like to be a bat?
The philosopher Thomas Nagel asked this question in a famous essay, first published in 1974. Most people today would assume that bats, like dogs and cats and other mammals, are not mere automata. They have experiences, which is to say that that have some sort of inner, subjective life. In other words, Nagel says, it is “like something” to be a bat. And yet, bats are so different from us that it is hard for us to imagine just what being a bat is like. How can we find a human equivalent for its powers pf echolocation, or its experience of flight? In comparison to human beings and other primates, Nagel says, bats are a “fundamentally alien form of life.” In particular, “bat sonar, though clearly a form of perception, is not similar in its operation to any sense that we possess, and there is no reason to suppose that it is subjectively like anything we can experience or imagine.” We cannot easily think ourselves into the mind of a bat.
Nagel’s question is really just a vivid example of a problem that has long been a matter of concern for Western thought. Even since Descartes, philosophers and artists alike have worried about the problem of other minds. Descartes makes subjective experience the ground for all certainty. I think, therefore I am: this means that, even if all all my particular thoughts are delusional or false, the fact that I am thinking them is still true. But how much of a reassurance is this, really? I do not experience anyone else’s feelings from the inside, in the way that I experience my own. Descartes worries that the figures he sees through the window might not be actual human beings, but “hats and cloaks that might cover artificial machines, whose motions might be determined by springs.” However absurd or paranoid such a hypothesis seems, there is no way to absolutely disprove it. Modern science fiction works — think of Philip K. Dick’s novels, or The Matrix movies — still take up this theme: they express the disquieting sense that the world, with all the people in it, is nothing more than an enormous virtual-reality simulation somehow being fed into our minds.
The best answer to this sort of paranoid skepticism is the argument from analogy. Other people generally act and react, and express themselves, in much the same way that I do: we all laugh and cry, groan when we are in pain, agree that the wall over there is painted red. On this basis, I can presume that other human beings must also have the same sort of consciousness, or inner experience, that I do. Of course, this is not an absolute logical proof; and it leaves open the possibility that other people might be shamming or acting: pretending to be in pain when they are not. And yet, the argument from analogy works pragmatically. As Wittgenstein put it, despite his own skepticism about the language of inner experience: “just try — in a real case — to doubt someone else’s fear or pain!” Only a sociopath would do so.
The real problem with analogy lies in the opposite direction: in the fact that we tend to extend it further than we should. We are so good at discerning other people’s feelings, desires, and intentions, that we tend to believe that these things exist even where they do not. We discern patterns in random bits of data. We attribute intention to deterministic mechanisms. We decipher messages that in fact were never sent. We assume that everything in the world is somehow concerned with us. Paranoid credulity is a worse danger than paranoid skepticism.
If we fail to grasp what it is like to be a bat, then, this is less because we fail to recognize it at all, than because we tend to anthropomorphize it unduly. We all too smugly assume that bats are just like us, only not as smart. We tend to subsume a creature like the bat under our own image of thought, forgetting that it might think and feel in radically different ways. For how else could we hope to understand the bat at all? But if we have a hard time grasping the mind of a bat, then how can we even hope to grasp the mind of a much more distant intelligent organism — for instance, an octopus? And what about — to extrapolate still further — the minds of intelligent beings from other planets? Peter Watts’ science fiction novel Blindsight tells the story of a First Contact with aliens who are more advanced than us by any intellectual or technological measure, but who turn out not to be conscious at all, in any sense that we are able to recognize or understand.
Watts imagines his aliens by inverting the argument from analogy. His novel’s title — Blindsight — refers to a well-documented medical condition in which people are overtly blind, but able to see unconsciously. Blindsight sufferers are not aware of seeing anything. But if you throw them a ball, they are often able to catch it; and if you ask them to “guess” the location of a light that they cannot see, they are usually able to turn in the right direction. Apparently their brains are still processing visual stimuli, even though the outcome of this processing is never “reported” to the conscious mind. Such nonconscious mental activity provides the analogy on the basis of which Watts imagines his aliens. In doing so, he manages disquietingly to suggest that consciousness might well be evolutionarily maladaptive, reducing our efficiency and our ability to compete with other organisms.
Watt’s speculative fiction is not an idle fantasy. In fact, nonconscious mental processes are not just confined to people who suffer from blindsight or other neurological disorders. Contemporary neurobiology tells us that most of what our brains do is nonconscious, and even actively opaque to consciousness. At best, we are only aware of the results of all our complex mental activity. The price we pay for conscious access to the world is an inability to grasp the mechanisms that provide us with this access. We cannot “see” the processes that allow us to see. As the neurophilosopher Thomas Metzinger puts it, “transparency is a special form of darkness.”
This puts the whole question of “what it is like” on a different footing. If I do not know what it is like to be a bat, this is because I also do not know what it is like to be a human being. Indeed, I do not even really know “what it is like” to be myself. My consciousness is radically incomplete, and it never “belongs” only to myself. Descartes’ “I think” is generated, and driven, by all sorts of nonconscious (and non-first person) mental processes. Other things think through me, and inside me. My own thought is merely the summation, and to some degree the transformation, of all these other thoughts that think me, and of which I am not (and cannot ever be) aware. Such nonconscious thought may well include — but is surely not limited to — what has traditionally been known as the Freudian unconscious. My thought processes are not self-contained, but broadly ecological or environmental.
In part, this is because all thought is embodied. As Alfred North Whitehead once put it, “we see with our eyes, we taste with our palates, we touch with our hands.” Today we might add that we see with our neurons and cortex, as well as with our eyes. But even this does not go far enough. We should also say that we see with the objects that reflect photons into our eyes. We hear with our ears, but we also hear with the things whose vibrations are transmitted through the air to us. We sense and feel by means of all the things in our surroundings that incessantly importune us and affect us. And these include, but are not limited to, the objects of which we are overtly aware. For the greater part of our environmental surround consists of things that, in themselves, remain below the threshold of conscious discrimination. We do not actually perceive such things, but we sense them indirectly, in the vague form of intuitions, atmospheres, and moods.
This vast environmental surround also subtends our use of analogy in order to grasp “other minds,” or to imagine “what it is like” to be another creature. Degrees of resemblance (metaphors) themselves depend upon degrees of proximity (metonymies) within the greater environment. Consider, for instance, the dog instead of the bat. Dogs are not intrinsically any more similar to us than bats. They operate largely by smell; if anything, this is even more difficult for us to imagine than operating by sound. Blind people can often learn to echolocate with their voices, or with the tapping of their sticks. But it is unlikely that any human being (at least as we are currently constituted) could learn to olfactolocate as dogs do.
Despite this, we feel much closer to dogs than we do to bats. We are much more able to imagine what they think, and to describe what they are like — even on points where they differ from ourselves. This is because of our long historical association with them. Dogs are our commensals, symbionts, familiars, and companions; we have been together with them for thousands of years. We share much more of a common environmental background with dogs than we do with bats. This means that many of the things that think within us also think within dogs — in a way that is not at all true for bats. Evidently, neither visual objects nor olfactory objects affect us, or think within us, in the same way that they affect, or think within, dogs; nonetheless, their common presence helps to bridge the gap between us and them.
No thought is possible without, or apart from, what I am calling the environmental surround. Doubtless this has been true as long as humanity has existed — indeed, as long as any form of life whatsoever has existed. But why is this situation of special concern to us now? Or better: why has it become so urgent now? I think there are two reasons for this, which I will discuss in turn.
In the first place, recent digital technologies have allowed us to grasp and account for the environmental surround, more thoroughly and precisely than ever before. Media theorist Mark Hansen writes of how digital microsensors, spread ubiquitously within our bodies and throughout our surroundings, are able to compile information, and give us feedback, about environmental processes that are not phenomenally or introspectively available to us. We can now learn — albeit indirectly and after the fact — about imperceptible features that nonetheless help to shape our decisions and our actions: things like muscles tensing, or action potentials in neurons, but also subliminal environmental cues. We can then use this information to reshape the environment that will influence our subsequent decisions and actions.
The science fiction writer Karl Schroeder pushes this even further. In his near-future short story “Deodand,” he envisions a world in which ubiquitous microsensors break down the distinction between subjects and objects, or between human beings, nonhuman organisms, and lifeless things. “Fantastic amounts of data” are not only collected for our benefit, but also “exchanged between the sand-grain sized sensors doing the tagging,” and ultimately between the “things themselves.” Once an entity has a rich enough datafeed, it implicitly declares its own personhood. Objects are able to speak and respond to one another, and thereby to assert, and to act in, their own interests. Schroeder’s story tell us that we must reject “the idea that there’s only two kinds of thing, people, and objects.” For most entities in the world are “a little bit of both.” This has always been the case; but today, with our microsensing technologies, “we can’t ignore that fact anymore.”
The second reason for the current importance of the environmental surround is a much more somber one. Our technologies — both industrial and digital — have devastated the environment through pollution, global warming, and the extermination of individual species and whole ecosystems. This is less the result of deliberate actions on our part, than of our unwitting interactions with all those factors in the environmental surround that imperceptibly affect us, and are themselves affected by us in turn. Climate change and radioactive decay are prime examples of what the ecocritic Timothy Morton calls hyperobjects: actually existing things that we cannot ever perceive directly, because they are so widely distributed in time and space. For instance, we cannot experience global warming itself, despite the fact that it is perfectly real. Rather, we experience “the weather” on particular days. At best, we may experience the fact that these days are warmer on average than they used to be. But even the coldest day of the winter does not refute global warming; nor does the hottest summer day “prove” it. Once again, we are faced with things or processes that exceed our direct perceptual grasp, but that nonetheless powerfully affect whatever we do perceive and experience.
Paolo Bacigalupi’s science fiction short story “The People of Sand and Slag” addresses just this situation. The narrator, and the other two members of his crew, are posthumans, genetically engineered and augmented in radical ways. They have “transcended the animal kingdom.” But their bodies and minds are not the outcome of any sort of Promethean, extropian, or accelerationst program. Rather, they have been altered from baseline human beings in order to meet the demands of a radically changed environment. They are soldiers, guarding an automated mining operation in Montana. The three of them share a close esprit de corps; but otherwise, they seem devoid of empathy or compassion. As befits their job, they are extremely strong and fast; when they are hurt, their wounds heal quickly and easily. Sometimes, during sex play or just for fun, they embed razors and knives in their skin, or even chop off their own limbs; everything heals, or grows back, in less than a day. For food, they consume sand, petroleum, mining leftovers, and other industrial waste. They live and work in what for us would be a hellish landscape of “acid pits and tailings mountains,” and other residues of scorched-earth strip mining. And for vacation, they go off to Hawaii, and swim in the oil-slick-laden, plastic-strewn Pacific. They seem perfectly adapted to their environment, a world in which nearly all unengineered life forms have gone extinct, and in which corporate competition apparently takes the form of incessant low-grade armed conflict.
In the course of Bacigalupi’s story, the soldier protagonists come upon a dog. The creature is almost entirely unknown to them; they’ve never seen one before, except in zoos or on the Web. Nobody can explain where it came from, or how it survived before they found it, in a place that was toxic to it, and that had none of its usual food sources. The soldiers keep the dog for a while, as a curiosity. They do not understand how it could ever have survived, even in a pre-biologically-engineered world. They take for granted that it is “not sentient”; and they are surprised when it shows affection for them, and when they discover that it can be taught to obey simple commands.
The soldiers are perturbed by just how “vulnerable” the dog is; it needs special food and water, and incessant care. They find that they continually “have to worry about whether it was going to step in acid, or tangle in barb-wire half-buried in the sand, or eat something that would keep it up vomiting half the night.” In their world, a dog is “very expensive to maintain… Manufacturing a basic organism’s food is quite complex… Recreating the web of life isn’t easy.” In the end, it’s simply too much annoyance and expense to keep the dog around. So the soldiers kill it, cook it over a spit, and eat it. They don’t find meat as tasty as their usual diet of petroleum and sand: “it tasted okay, but in the end it was hard to understand the big deal.”
From bats to dogs to posthumans: philosophy and science fiction alike explore varying degrees of likeness and of difference. The point is not to achieve certainty, as Descartes hoped to do. Nor is the point to conquer reality, or to think that we can master it, or even that we can really know it. The point is not even to “know thyself.” But rather, perhaps. to come to terms with the multitudes that live and think within us, which we cannot ever live and think without, but which we can also never reduce to ourselves.
