The Universality of Preconscious Experience: A Conceptual Outline

Scientific and Medical Network, 2023

We humans consider ourselves first and foremost thinking creatures – Homo sapiens, after all, means a “wise,” “knowing” or “discerning” species. But the greater part of who we are isn’t intellectual – it’s visceral and takes place beneath the threshold of awareness. Our mental activity, in fact, depends on the many subconscious bodily processes that keep us alive. This talk presents a thesis based on three possibilities: first, that feeling is the essence of experience; second, that the most primitive ‘feelings’ stem from the energetic processes of life itself; and third, that a capacity for feeling is built into the cosmos. Combining these perspectives, I propose a type of panpsychism where sentience is paramount – and where the feelings that percolate beneath consciousness can be conveyed across spacetime. This presentation draws on the work of neuroscientist Antonio Damasio, evolutionary biochemist Nick Lane, and author Annaka Harris (who explores consciousness). The different strands explored will weave into a unique tapestry.

Talk to Scientific & Medical Network: The Universality of Preconscious Experience November 24, 2023 First off, my thanks to David and Paul for inviting me to the virtual wine bar. I’ve been told my presentations can drive people to drink, so this seems like a perfect match. Here are five key points I’ll be covering. All relate to my contention that wakeful consciousness is not nearly as important as we presume. In fact, just the opposite – and I’ll be suggesting that the implications of what isn’t conscious are pretty significant. Let’s start with what each of us is doing right now. You’re probably sitting at a table or desk as I am…or maybe you’re seated more comfortably, enjoying dinner 1 or a drink. That’s all obvious. So is the fact that your conscious mind is enabling you to gather my meaning, second by second. But the bulk of what you’re doing right now is not hearing, not thinking, not reflecting. So what are you doing? You’re breathing, for a start. And much more: your cells are metabolizing, your blood is flowing, your neurons are firing, electrochemical signals are being exchanged between your brain and the rest of your body, and your digestive tract is quite possibly being given its evening exercise. Also, your immune system is somewhere between active and quiescent…your proprioceptive system is continuously calibrating your balance and position in space…and your senses are likewise monitoring the environment so that anything out of the ordinary – a dog’s bark, an itch, an odd smell – will come into clarity. 2 Our conscious, verbalizing selves depend upon these mundane but absolutely essential biological processes occurring beneath awareness. All of that makes possible what we notice, imagine, love, fear, anticipate, and regret – the mix that neuroscientist Antonio Damasio dubbed “the feeling of what happens.” Yes, consciousness at its essence is a feeling. The truth of the matter is acknowledged by more of Damasio’s colleagues all the time. Just consider the title of Christof Koch’s 2020 volume, The Feeling of Life Itself. Indeed, the general judgment now is that Descartes had it wrong. We ‘are’ primarily because we feel, not because we think. The late novelist Milan Kundera put it beautifully when he said: “‘I think, therefore I am’ is the statement of an intellectual who underrates toothaches.” 3 Just as the left side of our brain, which traffics in language, normally dominates the right side, so we don’t fully appreciate the extent to which the activity that comprises ‘us’ takes place unconsciously. Our consciousness is, to borrow a common metaphor, akin to the upper part of an iceberg: perhaps 10 percent visible and the rest underneath the water. From an evolutionary standpoint, the neocortex, which enables us to have fully self-conscious experience, is an upstart. It was predated by the limbic portions of the brain, which register and govern emotion. And those structures grew out of the brainstem, the seat of the most basic functions such as breathing, metabolism, instinct, and reflex. 4 One can posit, as Damasio has, that self-awareness is nothing more or less than a way to “mind the body.” However we look at it, consciousness – that pinnacle of human development – is tethered to, and dependent upon, a raft of bodily processes that are literally out of sight. For these reasons, I assert that sentience is fundamental, not consciousness. Sentience references that which we physically sense but may not apprehend…what we feel in our marrow but may not be able to articulate…what we dream but cannot remember…and what we may intuit but do not know for certain. A baby that cries because it’s hungry, thirsty or tired is not necessarily conscious, but it is most definitely sentient. The same can be said for a person who is comatose or who has lost most of her or his faculties due 5 to advanced age. The more we learn about other animals (since human beings are animals), the more we appreciate that they are sentient, too – regardless of how self-conscious they appear to be. It’s been a human conceit for far too long that other animals don’t have feelings, don’t make decisions, and don’t live lives that matter to them. Now, all sentient creatures are animate. Self-generated movement is, in fact, the most elementary way to distinguish a living thing. Movement connotes life; an animal that is immobile is either asleep, depressed, dead or playing dead. What generates movement? Energy, obviously – the energy produced in living cells. Whether we’re referencing electron, photon, phosphate, or sodium electricity, it’s generated as ions move through the 6 membranes of different cell constituents. In the allimportant process of oxidative phosphorylation, the movement of electrons in a transport chain releases energy, which in turn pumps protons from the mitochondria (the power stations of the cell) through the membrane of ATP synthase, an enzyme that then makes ATP, the cell’s all-purpose energy currency. Some of the ATP is used to pump sodium out of the cell, producing the electricity that ultimately powers us. Don’t worry, there won’t be a quiz about this  . Let’s just say that without these fundamental ingredients and processes, no creature could sense, move or feel…let alone possess higher degrees of self-consciousness and personal agency. 7 Here’s an intriguing question, posed by biochemist Nick Lane. Could even the simplest life forms, such as bacteria, ‘feel’ something when ions pass across their single cell membrane, and the electrical charge across that membrane changes? It’s quite a conceptual leap. But if we imagine, with Lane, that feelings emanate from the electrochemical pulse of life, then we can view sentience as compatible with the energetic metabolism of living things. A bacterium, of course, would have the most primitive ‘experience’ possible. This prospect yields a conception of all life along a continuum, with some degree of sentience fundamentally built in throughout – but with greater capacity for thought, deliberation, memory, reasoning, and imagination accruing to creatures, like ourselves, blessed with more complex brains and nervous systems. 8 The possibility also opens up to something like panpsychism – the ancient idea (now coming into vogue again) that the universe is alive, or at least contains the seeds of aliveness. But the concept I’m considering here is slightly (though meaningfully) different. Only living things would qualify on the sentience scale, not rocks nor mountains nor streams. While Heraclitus was undoubtedly correct in asserting that one can never step into the same river twice – indeed, that all of nature changes, from continents drifting to stars going supernova – I am excepting inorganic matter from the possibility of having an experience. Now, your intellect might protest that highlighting sentience somehow denigrates consciousness, in effect celebrating the proletarian over the elite. But to point out the vastness of sentience is not to make selfconsciousness any less marvelous. If fact, it opens up 9 quite an intriguing possibility for our conscious inspection. In her book Conscious, Annaka Harris suggests that consciousness is built into the cosmos similar to spacetime, gravity, and electromagnetism – as a continuous, pervasive field. Such a field would conceivably produce a wide range of experiential possibilities as it interacts with matter. Harris takes, as one example, our feeling differently moment to moment and place to place, especially as we’re affected by other people’s consciousness (through their words and actions). The encompassing prospect she raises is of a cosmos teeming with types and degrees of experience (and here I’ll quote her) – “flickering in and out, overlapping, combining, separating, flowing, in ways we can’t quite imagine.” 10 I should add that, yes, all of Harris’ references are to consciousness, not sentience. But, in a Twitter exchange, she agreed that sentience is the more appropriate term. I’ve had a similar brief conversation with Christof Koch, who agreed – with the understanding that [quote] “there is no Rubicon between sentience and consciousness.” That makes sense – there’s likely no bright dividing line – so I’ll continue to deploy sentience a way of referencing all the subconscious activity that goes on within us. If there is a universal field of sentience, I suggest that animate beings participate in it largely through their preconscious activity, as this makes up the greater part of who and what they are. It would mean that all manner of primarily sensory and emotional experience that doesn’t register consciously – hopes, fears, intimations, dim recollections – is the ‘stuff’ that conveys. It would 11 also mean that the sentient content of other creatures is part of the mix, just as ours is. So, is there evidence? I’m going to suggest there is – beginning with synchronicities or ‘meaningful coincidences’ whose hallmark is to take us unawares. In considering these, the first thing to realize is that their meaning is typically felt – it has a resonant, emotional truth. Further, synchronicities tend (as in dreams) to present a symbol or image connected with what we’re concerned with at that juncture. As psychologists, artists and advertisers all know well, feeling lends itself to imagery. The images evoked can be highly personal, highly communal, or both. But the stronger the feeling, the more affecting and widely understood that image is likely to be. 12 Anyone who’s ever experienced a seeming synchronicity knows how it tends to shake you up. You’re left wondering: what just happened? The same is true for other oddities that are difficult to explain: instances of seeming telepathy and precognition. A key point here is that these occurrences, too, tend to revolve around emotion – an emergency, for example, occurring to someone at a distance. Carl Jung, who introduced the concept with Wolfgang Pauli, referred to synchronicity as something numinous. Perhaps that impression owes to the lack of appreciation our conscious minds have for the vastness and depth of sentience. Just as each of us is continuously ‘placed’ in spacetime…and affected in unseen ways by gravity and electromagnetism… so we could be, in effect, bobbing in a sea of sentience. 13 It’s a humbling prospect for our conscious selves to consider. But human presumptions have been humbled before, and we’re no worse for wear. In fact, our conscious universe is all the richer for it. With that, I’ll stop and let this stuff sink in. I’m looking forward to what everyone thinks – or perhaps feels – about the prospect I’ve presented. It’s early afternoon here in the Washington, DC area, so a little early to be imbibing, but I realize the wine bar is open in the UK and it is a Friday, after all. Since conversation has been known to flow better with a nice glass or two, it’ll be a treat for me anyway. Let me just thank you – and point to my books for anyone who might be interested. My email address is also there if you’d like to drop a line. 14
