NOTES ON EMBODIMENT
- The distinction between mind and body is the source of the separation of humanity from nature. This sense of separation implies a belief in the possibility (and hope) for a mental or spiritual existence apart from the body and outside nature. This self-conceived identity is prompted by a carrot and reinforced by a stick. The carrot is the ability to abstract, to generalize, to imagine, to think with a self-conscious mind. The stick is the awareness of mortality and of the vulnerability of embodied life in nature. Together, these have motivated humans to withdraw from the wild in the ways we have been able: mentally into realms of imagination, reason, and concept; and physically into urban and technological environments. We live outside nature to the degree we have created these artificial realms as our lived world.
- We delude ourselves to think that there is a realm of spirit, mind, or ideality that exists independent of the body and the physical world. For, these realms exist within the context of a natural environment, in the human mind housed in a physical body. From an evolutionary point of view, they serve the body, and the natural world is the venue for all that happens. On the other hand, our relationship with that natural world, including the body, is unavoidably mediated by our ideas about them. Body and mind are inseparably functions of each other. But this lesson has hardly sunk even into the techno-scientific imagination, which continues to be enthralled by idealist fantasies, such as uploading minds to cyberspace, the universe as a vast (programmable) computer, or the Cartesian paranoia that you are “probably living in a simulation.” Paradoxically, despite its materialism, science continues to inspire a point of view outside nature.
- The concept of life in a virtual environment is nonsensical if mind is an organ of the body. We may hope to transcend some limitations of the human body—especially disease—and some troublesome social aspects that derive from our primate heritage—such as greed and patriarchy—but not embodiment itself. Despite religious and spiritual traditions, the consciousness we so value cannot exist unembodied. The technological quest for freedom from biological and physical constraints is inspired by traditional hopes to transcend embodiment, but must filter these hopes through the lens of scientific realism and common sense. We should view ‘soul’ and ‘spirit’, for example, not as literal entities but as embodied human qualities.
- While embodiment may not necessarily require a biological body, it does imply the same dependent relationship with a real environment that natural organisms have. Natural creatures are naturally programmed to pursue their well-being. We can imagine artificial creatures that would be differently configured and programmed. They might, for example, be essentially altruistic, perhaps indifferent to pain or their personal existence. (But then how would they come into existence in the first place, if not through a process of natural selection that conditions them to value that existence? Once alive, how would they persist?) We can imagine selfless artificial entities. (Indeed, Silicon Valley is busy creating them: chatbots.) But will these ever be creatures, or conscious? Natural organisms are conditioned by their survival needs within the real world. Generative AI is conditioned not by the real world but by traces of human discourse about reality, or traces of those traces. It is not (yet) embodied, with a vested interest in its own existence.
- Biologically embodied mind is existentially bound to take its sensory world as real; failure to believe in that reality can threaten survival. This involuntary realism is grounded in reproduction and natural selection, in such a way that pain hurts, sugar tastes good, and mortality is fearful. We can imagine a non-biological mind which, although embodied, could potentially apply an adjustable realism, with a keener sense of ownership of its experience. It would consider its experience to be a self-created simulation. The world would appear to it through a variety of optional models, each with adjustable confidence levels and degrees of engagement. Its mortality would be less fearful if distributed over multiple bodies or versions, either concurrent or successive. Such a novel agent could afford to treat perception as interpretation rather than as self-evident reality. The world given in the senses would be experienced as semiotic rather than ontological. It would consist of affordances to act upon when necessary, rather than an externally given reality. Such a mind would have expanded powers and freedoms. It might seem incomprehensible to us—or, at least inconsistent—because it could inhabit multiple perspectives without the sort of cognitive dissonance that would distress humans.
- An artificial being, or an augmented biological one, might be able to think fast enough to run detailed alternative simulations before acting. Though some form of metacognition could adjust levels of belief—the degree of realism experienced—there would still have to be a base layer of commitments, which are at least provisionally unquestioned, without which it could not act. (A mind that doubts everything can’t commit to anything. On the other hand, a mind that believes too readily is a gullible slave to fictions.) Some optimum arrangement should be possible—both for such an ideal artificial being and for ourselves today.
- The positive potential of all technology is to secure the long-term survival of what we value—whether that is our biological species, our notion of consciousness, or various ideals of being that have been conceived over the ages. The coveted prospects for artificial existence reflect ancient spiritual ideals. Whether or not we ever build “spiritual machines,” or artificial human successors, the issues surrounding artificial intelligence today prompt us to reconsider how to make the most of our natural body-bound potential. The dream of creating artificial life reflects deep aspirations for natural life. It should not distract us with fantasies of escape, but should redirect attention to the problems of being biological social creatures. The so-called Alignment Problem (how to make sure AI is aligned with human values) throws back in our face the need to align ourselves with each other and with the natural world. While it is appealing to escape the confines of biological embodiment, the project to do so is full of dangerous contradictions. We are just beginning to wake up to the potential hazards of artificial intelligence.
- Indigenous worldviews may show us a better way forward than Silicon Valley, which promises a world in which humans are displaced by AI. Instead of rebelling against natural constraints and embodiment, we could embrace them and rebel instead against our constraints within the global capitalist system—against the oppressions of perpetual growth, inequality, overproduction, overconsumption, and overwork, not to mention the resulting ecological disasters. We could insist on tools that improve the human experience instead of trying to create artificial minds with unimaginable forms of experience or no experience at all. Technology could be harnessed to improve life for the many instead of increasing the wealth of the few. It could be limited to the creation of useful tools, as opposed to artificial agents that are tool-users in their own right.
- If all ideas are provisional, then history is best seen as a series of trial efforts. We should feel free to reject any experiment—personal or collective—and to return to earlier arrangements, or to others never tried or yet to be imagined. Human history so far has been a vast brainstorming session of trial and error. We can sift for results that promise to work best toward embodied human thriving in the long run. That long-term goal must be the intention—not money, status, power, sex, or salvation.
