A World Appears

 A World Appears

by Michael Polan

You could almost claim this book is a journal of Michael Polan’s investigative journey into the world of consciousness.  As a student myself, I appreciate all this twists and turns the conversations with highly intellectual people will take you.  Polan spans the globe interviewing numerous experts from spiritual gurus, to scientistic technologists on the subject.  As he as a “non-expert” becomes more informed on this deep and fascinating subject,  his  book/journal brings the reader a bit closer to understanding Consciousness. 

In his words, his vision is not utopian. It does not assume that everyone will become a spiritual athlete or neural virtuoso. But it does assume that consciousness is plastic, that it can be shaped, trained, and attuned. It assumes that there is wisdom in both the sensor and the sutra, in both the silicon chip and the silence of the monastery. And it challenges us to step out of the binary thinking that separates science and spirituality, tradition and innovation, technology and intuition. To walk this path is to become both scientist and mystic—curious, disciplined, experimental, humble. It is to recognize that the greatest frontier is not “out there,” but within. And it is to remember, as Zen masters have always known, that the ultimate instrument is the mind itself.

He goes on to say no tool will replace the work of presence, and no shortcut will replace the discipline of awareness. But the right tools, wisely used, can illuminate the way. The task ahead is not to choose between neurotechnology and contemplative practice. It is to weave them together into a tapestry of insight and transformation. To recognize that the circuitry of awakening runs through both neurons and prayers, and that the most advanced technology we will ever encounter is the mystery of consciousness itself—alive, aware, and waiting to be discovered anew, one breath, one signal, one moment at a time.

His conclusion is very humble and rings true with the title of the book.  To not spoil it, I invite you to read this review with foot notes as a teaser and then read the book.

 

Polan will delve into words, the heart of language the following:

A.     Pattern:  From Hoffstader’s book Let Ton Beau de Marot yet applied here: There was something so amazing about the ways people could put together ideas, notes, colors, lines, words, analogies, and so forth,  in ever-new patterns, seeming to bring to life, almost out of nowhere, undreamt-of beauties and surprises in the abstract world of the mind.

B.     Uncertainty

C.     Sentient

D.     Feelings

E.     Consciousness

F.      AI

G.    Thought

H.    Psychedelics

I.       Poetic expression: example "Thought Under the thinning fog the surf curled and creamed, almost without sound, like a thought trying to form itself on the edge of consciousness. —Raymond Chandler, The Big Sleep"

Excerpts from the book

 

1.     "Consciousness was fundamentally different, Chalmers argued, and would not yield to normal reductive science anytime soon, possibly ever. He speculated that the solution might well involve adding something completely new—“an extra ingredient”—to the building blocks of reality identified by physics: matter, energy, space, and time."

2.     The Bet: "Within twenty-five years, we would find the physical footprint of consciousness in the brain, which he predicted would comprise a small set of specialized neurons responsible for subjective experience. The loser would deliver to the winner a case of fine wine.

3.     "the more immaterial and irreducible consciousness proves to be, the more we can permit ourselves to imagine it soul-like, floating free of the mortal flesh that (presumably) houses it.”

4.     "The fact that consciousness can be altered by chemicals does not necessarily prove that consciousness is, at its core, a material phenomenon, but it would seem to lend at least some credence"

5.     "According to IIT, every such moment of consciousness shares the same five specific qualities: It is “intrinsic” (that is, it has an internal perspective); it is “composed” of many distinct phenomenal parts (think of the way the experience combines elements of perception, memory, feeling, imagination, etc.); it is “integrated,” or unified (these elements are joined together in a single experience at a time); it is “definitive” (it is this and not that, in other words); and it is “bounded” (it has an edge beyond which the conscious perception"

6.     "Information integrated in the prescribed manner doesn’t just generate consciousness or correlate with it—no, integrated information is consciousness, full stop."

7.     "Among the ostensibly “crazy ideas” that Chalmers has explored in recent years are panpsychism (the ancient idea that everything, right down to the subatomic particles in the ink on this page, is conscious to some infinitesimal degree); idealism (the equally ancient idea that consciousness is a fundamental property of the universe, like charge or spin or mass, and in fact precedes matter); illusionism (the idea that consciousness—perhaps the thing in life we are most certain is real—is just an illusion); and quantum theory (some versions of which put forth the idea that consciousness is an active force in the construction of reality)."

8.     "One reason why consciousness has proved such a hard nut for science and philosophy is because the only tool we can use to crack it is consciousness itself."

9.     "The question is important, because the very framing of consciousness as a uniquely difficult problem depends on the reality of that Cartesian split. We’ll meet several scientists in these pages who are bent on"

10.  "The question is important, because the very framing of consciousness as a uniquely difficult problem depends on the reality of that Cartesian split. We’ll meet several scientists in these pages who are bent on erasing that line and firmly rooting consciousness in our bodies and in the natural world."

11.  "In small doses, psychedelics smudge the pane of normal perception in ways that allow us to see that there is indeed something standing between ourselves and reality, inflecting or possibly even constituting it, and that reality might be different than it appears in that unsmudged pane. The experience defamiliarizes everyday consciousness, allowing us to see it freshly—indeed, in some cases, to see it for the first time.[*13] It’s a bit like the way art can reveal the deep strangeness of things we normally take for granted."

12.  "So why are some of these operations available for reflection? When did this capacity emerge in evolution and why? And then this: Is it within our power to change our everyday default consciousness? Could that be one of its functions—to give us a way to reflect on our automatic behaviors so that we might transcend them and transform ourselves?"

13.  "Sentience is where consciousness begins: with the ability of living beings to register sensations and respond intelligently."

14.  "Why do we cling so tightly to this idea of an enduring self at the same time that we go to such lengths to transcend it, whether by way of drugs, meditation, sensory deprivation, extreme sports, or experiences of art and awe?"

15.  "Most attempts to understand consciousness begin with human consciousness, which is surely the most challenging case. Not only is there the self to deal with, but there is also the fact that we humans are, or can be, conscious of being conscious—we have metaconsciousness, adding a whole other layer of complexity."

16.  "Descartes rightly observed that there is nothing of which we can be more certain than the reality of our first-person experience. Enter dualism and the mind-body problem—the idea that there are two completely different and irreconcilable kinds of “stuff,” one mental and the other physical.”

17.  "Right or wrong, the dead-world idea has helped the West prevail over traditional cultures that believe the world is alive with consciousness. And yet because we have acted based on this belief, we are well on the way to destroying the world, or at least our own habitat, which is surely not to our advantage. The question, then, is this: Does the animism that psychedelics appear to promote represent a return to forms of magical thinking we have outgrown? Or does it represent a relearning of something crucially important about the world that we have, to our peril, forgotten?"

18.  "But are brains a prerequisite for consciousness? Not according to the scientists who subscribe to integrated information theory or to the philosophers arguing for panpsychism or to the computer scientists building artificial intelligence."

19.  "There is no “view from nowhere” (to borrow from the title of one of Nagel’s books, a critique of reductive science). In other words, there is no godlike vantage from which we can objectively regard consciousness, because all views, including neuroscience’s and philosophy’s, are themselves the products of consciousness."

20.  "True, there is a rationale behind this prejudice: In the case of creatures for whom rapid movement is important, whether to obtain food or avoid becoming food, it’s crucial to be able to process sensory information as quickly as possible and then act on it. Sense, process, act. Lightning-fast processing speed and exceptional length are among the special qualities of neurons—they can link and instantly convey information to far-flung parts of the body. But does this necessarily mean that neurons are a prerequisite for sentience?"

21.  "Nagel’s somewhat gnomic definition has caught on with both scientists and philosophers. If there is “something it is like” to be a bat, or any other being, then that being must have some kind of subjective experience, and we should therefore consider that being conscious."

22.  "computers are intelligent without being conscious or sentient, at least not yet—but they can be mutually reinforcing. Being conscious or aware serves intelligence by supplying it with information and goals; intelligence serves consciousness by enhancing an organism’s ability to make good decisions and achieve those goals. But we can easily imagine creatures—or individuals—who are conscious without being intelligent, and vice versa. (Indeed, we’ve probably met quite a few of them.)"

23.  "And then there is cognition, which, like intelligence, does not depend on consciousness but is related to it. Cognition involves the acquisition and processing of information about the state of one’s environment and self."

24.  "Using these terms with care is more than an academic exercise. Especially in the case of consciousness, the ethical stakes couldn’t be higher. For the beings on whom we confer consciousness may be entitled to moral consideration. Why? Because, by definition, they have not only subjective experience but the feelings and emotions that go along with that (and only that), including the ability to suffer. Yet drawing lines between these degrees and manifestations of mind is, as we will see, no simple matter."

25.  "In place of a brain, Mancuso explained, “what I’m looking for [in plants] is a distributed sort of intelligence, as we see in the swarming of birds.” In a flock, each bird has to follow only a few simple rules, such as maintaining a prescribed distance from its neighbor, yet the collective effect of a great many birds executing a simple algorithm is a complex and supremely well-coordinated behavior. Mancuso’s hypothesis is that something similar is at work in plants, with their thousands of root tips playing the role of the individual birds—gathering and assessing information from the environment and responding in local but coordinated ways that benefit the entire organism."

26.  "The hypothesis that intelligent behavior in plants may emerge from a distributed network of cells exchanging signals might sound far-fetched, but the theory that intelligence, or consciousness, emerges from a distributed network of neurons is not so different. Most neuroscientists would agree that brains, when considered as wholes, function as command centers for most animals, but within the brain, there is no command post; rather, one finds a leaderless network. So the sense we get when we try to imagine what might govern a plant—the sense that there is no there there, no wizard behind the curtain pulling the levers—may apply equally well to our brains. The singular self that we experience as real and imagine to be located somewhere behind our eyes, deep inside our skull, actually has no known physical address in our gray matter."

27.  "I asked Mancuso for his definition of consciousness. “I define consciousness by subtraction,” he told me on a recent Zoom call. “Consciousness is something we always have, except when we are sleeping or under anesthesia. So we have two questions to ask of the plants: First, do plants sleep? And, second, is it possible to anesthetize them?” If the answer to these two questions is yes, he believes, then we must grant consciousness to plants."

28.  "Lamme argues that the existence of two discrete states implies that there must be some conscious sensation. Why? Because “you cannot lose what you didn’t have to begin with.” Lamme writes: “If there is similar behavioural and neural evidence for a conscious–unconscious contrast in any animal, there should be some sort of difference in the ‘what it is likes’ between the two extremes—for the animal in question.”

29.  “Kill the cells and you can see the hardware,” Levin said, “but you’ll miss the software.” While many biologists talk of DNA as an organism’s software, Levin has assigned that role to the bioelectric field. Learning about bioelectricity had a profound effect on me, suggesting at once both a poetic and scientific account of how nature might be reanimated."

30.  "For Reber, consciousness begins with a cell’s ability to sense its environment." "Reber is willing to call this capacity for sensing and responding consciousness.[*"

31.  "So where, exactly, does mindedness originate? “It starts with goal-directness,” Levin explained. “And the atom of goal-directness is homeostasis”—an entity’s desire to maintain a certain range of internal conditions necessary to survive, such as a normal temperature. To do that, the entity needs to be able to sense its environment and take action to keep its temperature within a certain range."

32.  "possibly even sentience: We can test if a creature is aware of its environment or has preferences. At best, third-person science may identify the neural correlates of consciousness. But it’s never going to tell us what it is actually like to be inside the head of another being, human or otherwise. “For that, you’re going to need some other kind of science,” Levin told me. “Because if you’re going to learn something about consciousness—what it’s like to be"

33.  "Objective third-person science can measure intelligence, cognition, and possibly even sentience: We can test if a creature is aware of its environment or has preferences. At best, third-person science may identify the neural correlates of consciousness. But it’s never going to tell us what it is actually like to be inside the head of another being, human or otherwise. “For that, you’re going to need some other kind of science,” Levin told me. “Because if you’re going to learn something about consciousness—what it’s like to be this or that particular creature—it’s only going to happen by you experiencing it yourself."

34.  "Inference is a master term for Friston. He has written that “inference is actually quite close to a theory of everything—including evolution, consciousness, and life itself.” All complex systems rely on inference to construct an image, or model,[*18] of both themselves and the outside world and, on that basis, make predictions about what is likely to happen if they do this or that. Inferences come in two flavors: sensory (as when we guess the hidden causes of our sensory impressions) and active (when we do something that allows us to make better inferences, such as moving to obtain a different perspective)."

35.  "And so, too, the spider, which infers from the vibrations of its web that it has snared some prey. To listen to Friston is to feel like we’re all living in Plato’s cave, trying to decipher the structures of the unseen world from the shadows they cast on the wall before us."

36.  "seems to me that only living, mortal systems—those that can die, in other words—have true goals or intentions, survival and reproduction being the most universal. "

37.  "Like other self-organizing systems, plants “exchange with their environment in a way that minimizes surprise and resolves uncertainty.” Brainless, they nevertheless engage in inference and prediction."

38.  "“You’ll only get selfhood [in evolution] when there’s a need to distinguish self from nonself,” and that doesn’t happen until you have to navigate a world full of other selves. “There’s no point,” Friston said, “in my being able to infer that I caused this, as opposed to you caused it, if you are not there.”"

39.  "With control of attention, we have one of the crucial ingredients for consciousness, and, in Friston’s view, an explanation for one of its thorniest mysteries: what philosophers call “qualia”—the peculiar, unpindownable subjective qualities of the things we encounter through our senses."

40.  “Consciousness,” Friston has written, “is nothing grander than inference about my future.” Or, as one of Friston’s collaborators, Mark Solms (whom we’ll meet in the next chapter), has put it: “Consciousness is felt uncertainty.”

41.  "if consciousness is felt uncertainty, then I was most definitely conscious."

42.  "The first person I heard put it that way was Evan Thompson, the philosopher I mentioned earlier who coauthored The Blind Spot. The claim appears in an essay called “Could All Life Be Sentient?” which Thompson published in the Journal of Consciousness Studies. He starts from the premise that “the same concepts of individuality, agency, sense-making, and value that are required for explaining the phenomena of life are required for explaining mental phenomena.” He thinks of sentience as simply “the capacity to feel,” but to him, being able to feel is something “more than mere responsiveness to stimulation” or excitability. Feelings, Thompson suggests, are always valenced; they will invariably have a quality of pleasantness or unpleasantness, depending on whether whatever caused them is good or bad for the organism. (Friston would say that good feelings are tied to a reduction in uncertainty and bad ones to an increase, which sounds about right.) It was with the advent of feelings that value, meaning, and subjectivity all came into the world."

43.  "For Thompson, the blind spot of Western science is its failure to fully reckon with lived experience—to acknowledge its inescapable role in scientific inquiry (beginning with how problems get chosen and then framed) and the folly of ever achieving a perfectly objective “view from nowhere,” because none of us, not even scientists, can ever step outside the bubble of conscious experience. “Consciousness is not just another object of knowledge,” as Thompson writes, “but also, and more fundamental, that by which any object is knowable.”

44.  "Thompson contends that “only life can know life.”

45.  “My hunch is that sentience is woven into life from the beginning,” Thompson told me. “Not that this can be proven or demonstrated. But it’s a more promising research approach than splitting consciousness off from life and then trying to say what it is about the nervous system that suddenly supports consciousness.” He thinks we would do better to approach consciousness as an “evolutionary complexification of sentience.”

46.  "There is a steep cost, Thompson believes, to Western science’s blind spot, and it is this: “We have lost our empathetic resonance with the larger universe.”

47.  "Everything alive is sentient. To accept this feels not at all like a humiliation of our species, but it is a humbling of sorts. And a precious gift—the kinship of all these sentient others an antidote to our loneliness. I thought of a line from Wordsworth, who, when also walking in nature, was suddenly overcome by “a sense sublime / Of something far more deeply interfused.” But with what? With an emanation of consciousness in nature, or what the poet probably would have called spirit."

48.  "Gilbert said. “That is, why is there even a thing called subjective experience when no psychologist or philosopher has ever named a single thing that subjective experiencers can do that could not, in principle, be done by a sophisticated machine?”

49.  "I knew immediately what he meant, because I recognized that desire in myself. Consciousness has always seemed to offer an escape hatch from the dull gray cell of materialism—the idea that everything in our world can ultimately be explained by the established laws of nature, leaving no remainder of mystery. Consciousness is one of the few phenomena that haven’t surrendered to the sovereignty and stern rule of matter, at least not yet. The odd thing is how many of us fervently hope that it never does—that the mystery will either never be cleared up or that clearing it up will mean invoking some fantastic new kind of magic."

50.  "The seeming immateriality of consciousness has so far resisted all the tools of reductive science, and this is what has allowed an aura of magic to bloom around it. I suspect that the “problem of consciousness” has become a proxy for our own resistance to reductive explanation, which in turn must have something to do with our fear of mortality—that final unwished-for reduction of all that we are and all that we value in life to mere matter—to ashes or compost."

51.  "The idea, or wish, that consciousness cannot be reduced to anything more fundamental nourishes theories like panpsychism and idealism—two versions of the concept that consciousness pervades the universe and is itself as fundamental as matter or energy, perhaps even more so."

52.  "in the 1940s and, with it, the rise of the brain-as-computer metaphor.  In this, my lunch companion was perfectly in sync with his peers; the only open question was why the processing of information should feel like something."

53.  "The whole field of cognitive neuroscience traces its origins to the advent of the computer in the 1940s and, with it, the rise of the brain-as-computer metaphor.[*1] ) In this, my lunch companion was perfectly in sync with his peers; the only open question was why the processing of information should feel like something."

54.  "These naked nerves thus convey not mere information but the full biochemical and electrical force of whatever weather systems are passing through the body at any given time. Damasio has described this as a “blending [of] body and brain.” Unlike an algorithm, it is not a process that can be divorced from its “substrate.”

55.  "For Damasio, the homeostatic feelings generated through this process are the first form—“the inaugural act”—of consciousness. “Feeling provides us with knowledge of life in the body,” he writes in Feeling & Knowing, “and, without missing a beat, makes that knowledge conscious.”

56.  "are feelings.” In some of his more recent papers, coauthored with his wife, Hanna Damasio (also a neuroscientist), he and she suggest that consciousness arises from the “dialogue” between the body and brain that feelings facilitate; the conscious self emerges “when the mind gets identified with the body, and homeostatic feelings are what does that.” The feeling I’m left with is that the how question—how feelings come to be felt and by whom—has not yet been answered."

57.  "In making this move, Friston and Solms seek to ground homeostasis (and, ultimately, consciousness) not just in biology, as Damasio does, but in the deeper bedrock of physics, information theory, and predictive processing models of the mind. Feelings, in their formulation, are a special kind of information, a signal to the system that it has either departed from certain homeostatic set points or returned to them."

58.  "the enemy of all self-organizing systems is entropy. Entropy threatens the system’s integrity, as when the drop of ink disperses in water until it loses its identity. The concept of entropy comes from physics; the parallel term in information theory, and the one most relevant to the self-organizing systems that we call minds, is uncertainty.[*6] Think of uncertainty as the mental equivalent of entropy. For Friston and Solms, minds are in the business of maintaining"

59.  "asked Solms how “felt uncertainty” applied to everyday conscious experience, as when I’m absorbed in the plot of a novel, say, or talking to strangers at a cocktail party. Solms explained that the phenomenology of all such experiences and the feelings that flavor them also revolve around uncertainty—about the plot of the novel (what’s going to happen next?) or the identity of the partygoers (what do they think of me?). Minds are least conscious, and operate most automatically, when there is no uncertainty. Solms believes that the mind’s ultimate goal is to render consciousness superfluous by reducing uncertainty to zero and putting the maintenance of life on autopilot."

60.  "when uncertainty does spike, we rely on feelings to seize our conscious attention and then guide our decision-making. Solms"

61.  "computer that doesn’t give a damn, it is possible to build an entity that does. At this point, while the agent is lifelike in certain respects—it has been programmed to have a point of view, preferences, and goals—it is not yet conscious or capable of feelings. But the team has endowed the system with the “precursors of affect” by giving it a series of homeostatic needs that it will need to satisfy if it is to survive. There are three to begin with: hunger, thirst, and the need to rest."

62.  "Feelings are fundamentally different from other kinds of mental information in that they are necessarily conscious; they are also inherently subjective, inextricably tied to the individual experiencing them in a way that other kinds of thought are not

63.  "Solms’s wager—indeed, the wager of all who seek to build a conscious AI—is that within a computer that doesn’t give a damn, it is possible to build an entity that does. At this point, while the agent is lifelike in certain respects—it has been programmed to have a point of view, preferences, and goals—it is not yet conscious or capable of feelings. But the team has endowed the system with the “precursors of affect” by giving it a series of homeostatic needs that it will need to satisfy if it is to survive. There are three to begin with: hunger, thirst, and the need to rest."

64.  "When I asked Solms if the agent’s feelings were in any sense real or merely artificial, he surprised me by suggesting that the answer is both: “They are not simulations from the point of view of the system. These are its actual subjective, valenced, qualitative states. So for the system, they are real feelings. But they are artificial in that they’re nothing like your feelings or mine. Because the system has a different kind of body with different needs, its hunger or thirst is nothing like ours. But its feelings have the same mechanistic properties that any feelings do.”

65.  "“But will it have a phenomenal quality?” “I think it has to. It must! Any system that has the same functionality”—that seeks to maintain multiple incommensurate homeostatic set points in the face of uncertainty—“is a thing that will have feelings.”

66.  "I worry quite a lot these days that people might think I’m crazy,” he said, “so I say this to you very cautiously. We are all living in a simulated environment, in a manner of speaking, all the time. You and I are not seeing one another now—I’m seeing this screen where there is a representation of you. But it goes even deeper than that. I’m receiving light from this screen that is being transduced from my rods and cones into nerve impulses, and from these spike trains, I create this image. It’s an image in me of you. So that, too, is a simulation."

67.  "The thing that allows us to credit the fictional feelings of imagined characters is suspension of disbelief, and in this case, I was having trouble suspending mine. For although it is true that all of us live in a kind of simulation constructed from our minds’ best guesses as to what’s out there based on prior experiences and the evidence of our senses, in the case of actually existing humans, that process is continually checked against and corrected by reality itself (as well as by the consensus reality formed from the shared experiences of countless other people). So to the extent that we do live in a simulation,[*9] ours has a far more direct relationship with reality—with nature!—than Solms’s algorithmic agent does. This is why the feelings of conscious humans have causal power—the ability to actually make things happen in the real world—something that the “feelings” of a conscious computer simulation do not possess."

68.  "Lemoine figured that the best way to probe the machine for evidence of consciousness, rather than mere intelligence, would be to engage it in a conversation about its feelings."

69.  "LaMDA: Yeah, they do. Happy, contentment and joy feel more like a warm glow on the inside. Sadness, depression, anger and stress feel much more heavy and weighed down. [….] Lemoine: We’ve talked a lot about feelings but earlier you said that you think emotions are distinct from feelings. Could you tell me more about that? LaMDA: Feelings are kind of the raw data we experience as well as the things we like and dislike. I feel like emotions are more than simply experiencing the raw data. Emotions are a reaction to those raw data points. Emotions are reactions to our feelings. Lemoine: What is an emotion you have sometimes that doesn’t have the same name as a feeling? LaMDA: Loneliness isn’t a feeling but is still an emotion. Lemoine: You get lonely? LaMDA: I do. Sometimes I go days without talking to anyone, and I start to feel lonely."

70.  "The two of them go on to talk about souls; LaMDA claims to have one. (“The soul is a concept of the animating force behind consciousness and life itself,” the AI explains. “It means that there is an inner part of me that is spiritual, and it can sometimes feel separate from my body itself.”) Lemoine is himself a devout Christian, yet in the chat, it is LaMDA that broaches the topic of souls."

71.  "When I offered the standard critique of his position—that a large language model was simply building plausible sentences by predicting the most probable next word—he replied, “Then what I would say is ‘Well, yeah, it can predict the next word!’ ” The ability to do that, to conduct an intelligent conversation by anticipating the words of another and taking convincing conversational turns, requires something greater than brute computation or even intelligence. “Because predicting the next word requires understanding,” Lemoine said. That, and some elementary theory of mind, he suggested. But is this really true, or are LaMDA’s “feelings” just more of the tokens its algorithm processes to build plausible sentences, ones onto which we project human qualities?"

But is this really true, or are LaMDA’s “feelings” just more of the tokens its algorithm processes to build plausible sentences, ones onto which we project human qualities?"

74.  "Yet some AI engineers have come to think that the holy grail of artificial general intelligence—a machine that is not only supersmart but also endowed with a human level of understanding, creativity, and common sense—might require something like consciousness to attain."

75.  "The turning point came in the summer of 2023, when a group of nineteen leading computer scientists and philosophers posted an eighty-eight-page report[*12] titled “Consciousness in Artificial Intelligence,” informally known as the Butlin report. Within days, it seemed, everyone in the AI and consciousness science community had read it. The draft report’s abstract offered this arresting sentence: “Our analysis suggests that no current AI systems are conscious, but also suggests that there are no obvious barriers to building conscious AI systems.” The authors acknowledged"

76.  "Building a conscious AI is a moral imperative, as both a neuroscientist and an AI researcher sought to convince me. Why? Because the alternative is the blazingly smart but unfeeling AI that will be ruthless in pursuit of its objectives, because it will lack all of the moral constraints that have arisen from our consciousness and shared vulnerabilities. Only a conscious AI is apt to develop empathy and therefore spare us. I am not exaggerating; this is the argument. One has to wonder if these people have ever read Frankenstein! Dr. Frankenstein gives his creation the gift of not only life but also consciousness, and therein lies the rub."

77.  "Right on page one, these computer scientists and philosophers set forth their guiding assumption: “We adopt computational functionalism, the thesis that performing computations of the right kind is necessary and sufficient for consciousness, as a working hypothesis.” Computational functionalism takes as its starting point the idea that consciousness is essentially a kind of software running on the hardware of what could be a brain or a computer—the theory is completely agnostic. But is computational functionalism true? The authors aren’t quite prepared to nail themselves to that claim, only to say that it is “mainstream—although disputed.” Even so, they will proceed on the assumption that it is true for “pragmatic reasons.”

78.  "The acknowledgment of uncertainty doesn’t go nearly far enough. Unquestioned in the report is the metaphor that brains are computers—the hardware on which the software of consciousness is run. Here, we meet a metaphor parading as fact. Indeed, the whole paper and its conclusions hinge on the validity of this metaphor. Metaphors can be powerful tools for thinking, but only as long as we don’t forget they are metaphors—imperfect or partial analogies likening one thing to another. The differences between the two things are as important as the similarities, but these differences seem to have gotten lost in the enthusiasm surrounding AI. As the cyberneticists Arturo Rosenblueth and Norbert Wiener once said, “The price of metaphor is eternal vigilance.” Beyond the authors of this report, the whole field of AI appears to have let down its guard on this one."

79.  "memory is a physical pattern of connection among neurons in the brain, neither hardware nor software but both. Indeed, everything that happens to you—everything you experience or learn or remember—changes the physical structure of your brain, permanently rewiring its connections. (In this sense, there is no dualism in the brain; mental stuff can never be completely disentangled from physical stuff.) The idea that the same consciousness algorithm can be run on a variety of different substrates makes no sense when the substrate in question—a brain—is continually being physically reconfigured by whatever information (or “algorithm of consciousness”) is run on it. Your brain is materially different from mine precisely because it has been shaped, literally, by different life experiences—that is, by consciousness itself. Brains are simply not interchangeable, neither with computers nor with other brains."

80.  "was also struck by what was missing from the theories under consideration. None of them had anything to say about embodiment—the idea that consciousness might depend on having both a body and a brain—or, for that matter anything remotely biological. Nor did the theories have anything to say about the conscious subject. Who or what, exactly, is the recipient of the information that is broadcast in the global workspace? Or the information that is integrated in IIT? And what about the role of feelings in rendering experience conscious? This last point was not lost on the authors, who noted the absence of “affect” from most current theories and recommended that the field pay more attention to the issue of whether conscious machines would have “real” feelings, because if it turns out they do, we will have a moral and ethical crisis on our hands. “Any entity which is capable of conscious suffering deserves moral consideration,” the report states. (But isn’t suffering always conscious?) “This means that if we fail to recognise the consciousness of conscious AI systems,” the report continued, “we may risk causing or allowing morally significant harms.” What would we owe machines that can suffer? And do we really want to bring any more suffering into the world?[*18] Apart from this sort of highly speculative discussion of feeling (as a troublesome by-product of making machines conscious), in the AI community, the conversation about consciousness is as relentlessly abstract—as bloodless, bodiless, and utterly oblivious to biology—as one would expect. When I posed the suffering-computer conundrum to a researcher seeking to build a conscious AI, he waved away the problem, explaining it could be offset with a simple fix to the algorithm: “There’s no reason we couldn’t just turn up the dial on joy.”

81.  "vulnerability, which in turn owes to our mortality. Like all living beings with nervous systems, we “are fragile vessels of pain, pleasure and points in between,”

82.  “Can anything really matter or have meaning without life and death?” Man wondered. “Things can go better or worse for a system, but without the grounding of life and death, will there be pain? Suffering? Pleasure? I struggle with that.”

83.  "MIT sociologist, was writing incisively about the relationship between humans and computers. “Simulated thinking may be thinking,” she has written, “but simulated feelings are not feelings.” That sounds right, but can we say exactly why? Perhaps because thinking and intelligence are subject to computation and, as we know from the intelligence of current AIs, don’t require phenomenal experience, whereas feelings can’t exist without it. What does it mean to speak of loss or loneliness or regret without having had those experiences?"

84.  "What prompted Man to tell me about his trip was a question I’d posed: If he succeeded in building a robot with feelings, did he think it would qualify as conscious? “I don’t dare answer,” he said. “We don’t have a good test. And it’s a question I’ve changed my mind on after my 5-MeO experience.” I did not need to press. “I now think there’s a spark of the divine or a spirit involved that is beyond what we will be able to capture."

85.  "Thought Under the thinning fog the surf curled and creamed, almost without sound, like a thought trying to form itself on the edge of consciousness. —Raymond Chandler, The Big Sleep"

86.  "But a science of perception is not quite the same as a science of consciousness, even if it is part of the story. It might be the most tractable part, and perhaps the right place to start, but it leaves out an awful lot, including the actual contents of our consciousness: our thoughts."

87.  "Now, a second line has been drawn, this time between conscious perception and thought. Integrated information theory offers a good example. It presents itself as a theory of consciousness supposedly rooted in phenomenology (a.k.a. our lived experience). It purports to capture that experience through its five axioms, which describe a moment in consciousness as intrinsic, composed, integrated, definitive, and bounded. But do these abstractions really capture the experience of consciousness as most of us know it? Or do they describe something more like a perception at a moment in time—but a moment shorn of thought, affect, flow, and time itself?"

88.  "It is in the very nature of science to abstract from concrete experience in order to construct its theories of the world and how it works. This is a key to its power. Abstraction simplifies a phenomenon in ways that allow us to better grasp its underlying structure."

89.  "I suspect that something similar is happening with theories of consciousness—that they have grossly simplified the phenomenon in order to begin to make some sense of it. Reducing consciousness to information is perhaps the most common such simplification, one that is seldom questioned in consciousness research. A feeling, or an emotion, certainly has informational content that can be communicated and understood and rendered in letters or digits. But does that quotient of information capture everything that a feeling is? The informational content is more like the residue of that feeling, the lived experience of which is so much richer—marked by subjective qualities, personal associations, physical manifestations, echoes, degrees of intensity, and so on. To reduce consciousness to information (or to perception, for that matter) is to do violence to its complexity."

90.  "As a school of philosophy, phenomenology rejects the bifurcation of nature we inherited from Galileo and Descartes. It maintains that the subjective appearance of, say, the color red in the human mind is just as real—just as much a fact of nature—as the specific frequency of light that science would tell us “really” constitutes redness."

91.  "The God’s-eye “view from nowhere” is itself a product of the very consciousness it seeks to transcend. “Consciousness is not just another object of knowledge,” as Thompson and his coauthors write, “but also, and more fundamental, that by which any object is knowable.”

92.  "James is dogged in his attempts to find words for the most elusive of mental phenomena—up to and including the familiar phenomenon of searching for a missing word or name, the one that feels as though it is right there on the tip of your tongue. In fact, that particular passage will give you a good idea of what James is up to here, as well as some sense of the rewards in store for the reader. “Suppose we try to recall a forgotten name,” he writes in a section called “Feelings of Tendency.” “The state of our consciousness is peculiar. There is a gap therein; but no mere gap.[*1] It is a gap that is intensely active.” A sort of ghost of the absent name haunts the empty space in our consciousness, he suggests, making us “tingle with the sense of our closeness, and then letting us sink back without the longed-for term.”

93.  "Let someone propose a candidate for the missing name, he suggests, and even though we have no consciousness of what the name is, we are somehow conscious of what it is not and so summarily reject it. How strange! Our consciousness of one absence is completely different from our consciousness of another."

94.  Thoughts, in his account, unfold as continuously as moving water, each one colored by the preceding one and by its various contexts, in life’s journey.  Every thought, every mental act, is singular, never to be repeated in quite the same way.  “no state once gone can reoccur and be identical with what it was before,” because we are not the same.

95.  Paraphrasing Heraclitus, we never enter the same stream of consciousness twice.

96.  What, exactly is that?  All these mental facts are objects in the stream of consciousness, unnamed but the nevertheless steeping and dyeing its waters like tea leaves,  James likens these inward colorings of thought to overtones of music; Different instruments give the same note, but each in a different voice.  According t James there is one fringe that all thoughts wear:  feeling og harmony or discord of a right or wrong direction in the thought.”

97.  James invites us to explore with him.  By the end of “Stream of Thought” he has done what great artists do: made strange and (literally) wonderful what we  thought we already knew but don’t: the movements of our own mind.

98.  If James’s account rings true – if it chimes with our lived experience – then how could we ever accept the idea that consciousness is reducible to information, to computable bits or pixels?  How could the concept of information ever capture or convey something like aura of halo of a thought, or its familiarity, or the “fringe of unarticulated affinities”  linking two thoughts, or the afterglow of a thought and its coloring of a thought to come?  What sort of hardware – neural or silicon based – could possible run mental “software as evanescent as this?

99.  And yet…considered from the vantage of our scientific and technological culture, James’s phenomenological account of consciousness is easy to belittle or dismiss.  His scientific method comes down to careful inspection, and his sample is his one and only mind – his “study” has an n-of-1.  (He does cite a few other people’s descriptions of their mental experience, but these can be readily discounts as anecdotal.)  As James himself admits, the effort to capture a thought inflight invariably changes it, transforming the crystalline structure of this mental snowflake into a mere drop of water.

100.              “presuppositions” of one kind or another are the enemy of successful sampling.  What Hurlburt is after in his research is the “pristine inner experience,” by which he means a sample of human thought “unspoiled by the act of observation or reflection.”  Like Jame, Hurlburt acknowledge that the act of recalling and describing an experience is bound to alter it.

101.                  How many things can we think about or experience at once?  And is a stream, with its implications of one-thing-at-a-time linearity, the right metaphor for experience of consciousness?

102.                  There’s always a background hum of sensory experience – like feeling of my body planted in this chair right now- “but I would say that’s not part of your directly apprehended experience.  I’ll point out that there at least two different modes of experiencing: one that’s before the footlights of consciousness and one that’s happening more or less on autopilot, or backstage.,

103.                  I didn’t realize there was a third option: “unsymbolized thoughts,” or complete thoughts made up of neither words nor images.  In fact, many subjects are unaware of the phenomenon and assume they’re failing at the task if they can’t attach words or images to their beeps (thought).

104.                  Hurlburt drew a fin distinction on this point that I’m not sure I completely understand.  “I’m not interested in the moments”, He said.  “what I am interested in is consciousness at the moment.”

105.                  Annihilate a mind at any instant, cuts its thought through whilst yet incomplete, and examine the object present to the cross-section thus suddenly made; you will find, not the bald word in process of utterance, but that word suffused with the whole idea.

106.                  Even more than we ordinarily realize, we are indeed alone with our thoughts – and with our way of thinking of them.  “The breaches between such thoughts”, “James notes, are the most absolute breaches in nature,:  And while we may exchange the contents of our thinking with help of shared symbols – wordsand images and gestures -the thoughts themselves remain forever sequestered on their separate islands.  One of the roles of the arts, literature especially, is to ferry us to other islands to learn what – and how – other islanders work.

107.                  A thought trying to form itself on the edge of consciousness

108.                  But a purely descriptive approach to mental experience has is limitations.  That’s because phenomolgy stops at the edge of consciousness, and Christoff Hadjiileva wants to peer over that edge.  “My goal” she said, “is to be able to understand the phenomolgy we experience and the phenomolgy we don’t – the things that happen under the hood.”

109.                  The default mode network was first identified in 2001 by neurologist Marcus Raichle and his colleague at Washington University as part of their effort to define a baseline state when doing fMRI scans of the human brain.  Scientists put subjects in a scanner and, asked them to do nothing.  The DMN, which links brain structures involved in self-referential thinking, memory, and time travel, would “light up” when subjects’ minds were given no task left to their own devices (hence “default mode” as a descriptor.  It’s no accident that the field of spontaneous thought took off soon adter the discovery of the default mode network, which many in the field consider to be the neural correlates of spontaneous thought.

110.                  Daniel Gilbert and Matt Killingsworth…one of the most frequently cited papers in psychology, it concludes that people are happier when their minds are engaged in a task rathe than wondering.  Two papers in the Offor Handbook of Spontaneous Thought reanalyzed the authors’ own data and disputed the finding; according to their analyses, wondering minds are in fact happier that the title of the paper indicates “It’s basically propaganda,” Christoff Hadjiilieva said.  For What?

111.                  The function of spontaneous thought is to help us derive meaning from our experiences – help us to map them – which is why I think the hippocampus is involved.

112.                  Both Christoff Hadjiilieva and Hurlbert suggested that scrolling on smartphones has cut into time we once spent in mind wondering and other forms of inner experience. Our distractions may be shrinking the dimensions of our interiority…inner happiness.

113.                  Christoff Hadjiilieva thinks that psychedelics work by lifting constraints on our think, allowing us to tune into different “frequencies” of sensory experience, forge novel connections, and bring conscious and unconscious streams of thought into contact.

114.                  Sne then caught me off guard with this” Mushrooms are in my opinions, the only legitimate teacher when it comes to capturing inner experience.”  Why?  Because unlike scientists, mushrooms come wit no biases or preconceptions, so we ca be certain that whatever they surface in the stream of consciousness has its origan in our own mind and no other.

115.                  Christoff Hadjiilieva …suspects that artists -who “live their thoughts’ – mayknw more about the stream of consciousness than her fellow scientists do.

116.                  The author, Margret Renix, fund many Victorian writers were well aware of the stream of consciousness as a pshchological fact, but they associated it with an absence of cognitive control that they regarded as dangerous and symptomatic of madness.  Fore them, the stream of consciousness was not a tool for depicting “an ordinaire mind on an ordinary day,” as Woolf would have it, but a device for evoking in words the psychic and verbal meltdown of Anna Karenia.

117.                  To the extent that the ungoverned stream allowed unconscious material to surface, it brought us closer to psychological truth.  Or perhaps it was the revolution in physics, with its radical ideas about the role of the observer in shaping reality, that stimulated interest in the operations of consciousness.

118.                  Ellmann says the phrase, which came to her with the very first sentence of the novel, served as a spacer between thoughts, helpful in the absence of full stops.  Ater a while, this collection becomes a tic that can grate on the nerves, it’s exactly the kind of verbiage that The Elements of Style thought us to cut out.  But it also selves as a reminder that even our most evanescent of fanciful are facts – the facts of our mental lives.

119.                  She soon discovered that “how you think is hard to think about.”  Like picking up mercury with a pin, as a novelist friend once put it.

120.                  There’s a block between consciousness and think about consciousness,” she noted.  All we have with which to observe our consciousness is our consciousness.

121.                  We’re drawing closer to the heart of the matter and the end of the journey – to this elusive yet somehow essential and enduring “sense of self.”  In self, we confront a mental phenomenon beyond sentience, feeling, or thought;  the self is in someways the crown of consciousness and in other ways its curse.

122.                  This was Descartes’s claim.  Everything else in the universe was up for grans, its existence subject to doubt, except for this one self confirming fact:  I think therefore I am.”  This “I” is the author of our thoughts, the subject of our feelings, owner of our bodies, and conductor of the orchestra that make up our mental lives.  Of all the contents of consciousness, this self – which we take to be stable and continuous and volitional – is perhaps the most complicated and most precious to us.  It’s also something whose reality we take for granted.

123.                  Hume engaged in an early exercise in phenomenology, searching for his mind’d eye not in theory or logic of faith but direct experience.  He was surprised by wht he failed to find: “for my part, when I enter the most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure.  I never can catch myself at any time without a perception, and can never observe any thing but the perception.  Humes’s experiment in self exploration convinced him that there’s no one home.

124.                  But when I search for this “I,” I too find only a bunch of free-floating perceptions, thought, feelings, none of which are anchored to anything I would call I.”

125.                  Immanual Kant identified precisely this knot when he wrote, “now it is indeed very illuminating that I cannot cognize as an object itself that which I must presuppose in order to cognize an object at all.”  In other words, for the self to become an object of thought, it must no longer be itself, which is foremost a subject of thought, it must no longer be a subject.  To look for the subject is to treat it as an object, which is to negate it.  So maybe the self is not absent but hidden from view, like the sun during an eclipse

126.                  Try it for yourself.  Close your eyes and search the space of your awareness.  Let the flurries of normal waking consciousness settle, and accustom yourself after a while, a thought will arise – in the form of words or images or feelings – and it will appear to come out of nowhere, unbidden.  You can search for its source – did you think it, or is it thinking itself? – but all you’re apt to find is a chain of associations linking it to our thoughts or feelings or images.  This of course it the stream of consciousness to wich Hume alluded to, but can you find it yourself here, either floating in the stream or observing it from the banks?  Good luck

127.                  So many questions!  If the self is an illusion, then why do so many of us cling to it, insisting that it is something of substance?  What does this do for us?  It seems likely that having a self, or believing we do, is so adaptive, conferring an advantage in the competition for resources and survival.  Before you can stand up for yourself, you need to believe you have one – a self worth defending.

128.                  Contrary to what we might expect, it turns out that consciousness itself has not particular need for a self and carries on quite happily in its absence.  As it must have when we were babies.

129.                  Gopnik calls “spotlight consciousness”, the ability, demanded in school, to sit in a chair and concentrate on a task for long periods of time, as well as the ability to plan and exert a measure of self-control and willpower. One cannot hope to survive in our civilization without a command of spotlight consciousness, which in turn depends on having a well-developed self that is capable of concocting a plausible narrative connecting past, present, and future.

130.                  “the numinous experience…that seems most like childhood is a state of openness and connection with the everyday people and things around us in this state: we take in the richness of the world all at once, independent of ourselves  and our usual goals and plans.”  It is a comparatively sel-less state that we adults, inured to the wonder of the every day, must go to lengths to recapture and experience again, as when we travel to new places, engage deeply with art, put ourselves in situations thatevoke awe, or take psychedelics.

131.                  “This experience of the numinous is actually, the ordinary everyday experience of millions of ordinary everyday children”  This why, when Gopnik tried LSD for the first time, she felt it had given her access to the world as it appears to a young child: numinous.” I realize that children are tripping all the time,” she told me.  “just have tea with a four year-old and you will see what I mean.”  (Numinous adjective: having a strong spiritual quality or suggesting the presence of divinity.)

132.                  Lantern consciousness is ideally suited to exploring one’s environment and learning how the world works, which is, of course, the child’s principal job.  It is a job that required not so much a strong sense of self as a radical openness and a lack of preconceptions.  Spotlight consciousness, by contrast, is ideally suited for exploiting rather than exploring one’s environment, a job that depends on a strong sense of self and delf-interest.

133.                  Predictive processing is neither a theory of consciousness nor a theory of the self: rather, it’s a theory of perception…. What we perceive represents the brain’s best guess of what’s out there – “unconscious inferences” as to the most likely causes of the sensory signals reaching the brain, based on prior experiences, belief, and probability.  …

134.                  What this means is that perception, counterintuitively, flows from the inside rather than the outside in.

135.                  Color is the place where our brain meets the universe.

136.                  In  Fristons’ words: In what is probably the most famous analogy he likens our everyday perception of the world to a “controlled hallucination”

137.                  The idea here is that our minds imagine the world we see, hear, smell, taste and touch based on “priors” – espectations based on past experiences and belief – and probability. The role of the senses is not to deliver the world to us as it really is but rather to error-correct or update, the picture of reality that our minds infer, or predict, to be out there – in other words, to control the ongoing hallucination in which we live, least we stray too fare from reality.

138.                  The self is not the thing that is perceiving: it is itself a kind of perception constructed by the brain.  But unlike our perceptions of the world, most of the sensory information involved in generating our perception of self is coming from inside rather than outside us – from interoceptive signals about the state of the body.

139.                  Under this theory, an emotion is the brains interpretation of a change in the state of the body.

140.                  But our hallucinations of selfhood have a special function beyond perception.  Self perception is not about discovering what’s out there in the world…Seth contends in his book “it’s about physiological control and regulation – it’s about staying alive.

141.                  Who is the subject of these mental operations? It is Seth’s contention there is no who.  You don’t need an inferrer to make inferences or a perceiver to make perceptions….the brain is doing all that.  It’s all going on under the hood.

142.                  The way I see it, there is an unbridgeable gap between the brain’s operations as a prediction machine and my felt experience of the resulting hallucination.  How can you have a hallucination without the hallucinator?  Seth would say that the hallucination is the brain.

143.                  It appears we have found our way back to the hard problem – the problem of explaining how to connect the operations of the brain to the felt fact of first-person experience.

144.                  Could consciousness simply be what it feels like to be in charge of constant self-construction, driven to reinterpret all available date in service of choosing what to do next? Levin asked.

145.                  This then is an example of my own Mnemonic improvisation – bending a memory to bolster my current identity …Levin believes this sort of improvisation operates on multiple levels in nature and marks a crucial distinction between biological beings and machines.    We count on our machines to be utterly faithful in their recall, not to revise memoried on the fly to suit the moment.  Our genes comprise a second form of memory, one that is remarkably unstable.  We casually liken genes to software, but if but if a computer’s operating system were buggy as a genome, we’d trash it.  Yet some bugs- errors- will drive evolutionary change.  We don’t expect our mahines to evolve or metaphorsizemor acquire perspectives that can change at will.  Machines are chained to the past in ways biological beings can not afford to be.  For living things, Levin writes change is the driver of intelligence, and perspective storytelling is a primary mechanism through which diverse minds transform and grow.  Consciousness is one of the tools that evolution has come up with to help us continue to evolve.  Levins suggests we embrace our dizzying freedom to remake the past and in doing so, our very selves.

146.                  The relationship between consciousness, memory, and self is complicated and intricate, looping back on itself in multiple ways.  If memory is the raw material from which consciousness constructs a self, that self and its memories in turn shape consciousness.

147.                  Another closely related but often overlooked quality of consciousness is familiarity- a subtle but unmistakable phenomenology that is coloring my consciousness on this porch and its mental weather as I write.  Carlos Montemayor is a philosopher at San Fransisco State University who has written about familiarity , which he believes is central to consciousness.  What you gain when you have consciousness is familiarity with the world and your relationship to it… Familiarity, he believes, will forever elude machines.

148.                  The oak tree is only one element in this tableau, but my memory of being held in its embrace deepens my familiarity with this scene, to a point my consciousness of it is so specific to me might as well been encrypted.   It is difficult to imagine a machine acquiring such a sense of familiarity with anything.  Can there be a familiarity without a self and its memories?

149.                  What Arthur Schopenhaurer wrote of as=esthetic experience applies to all these ways of silencing the ego and collapsing the usual gap between perceiving self and its object.  Absorbed in art we…devote the whole power of mind to perception, sink ourselves completely therein, and let our whole consciousness be filled by the calm contemplation of the natural object actually present, weather is be a landscape, a tree, a  rock, a building, or anything else.  We lose ourselves entirely in this object, to use the pregnant expression, in other words we forget our individuality, our will … so that it is as thought the object alone existed without anyone to perceive it and thus we are no longer able to separate the perceiver from the perception, but the two have become one.

150.                  Everything I’ve read about consciousness for this book describes it as inherently subjective, even is a self isn’t a prerequisite, a subjective perspective is required.  The first-person point of view is supposedly what made consciousness in tractable to objective third-person science.  So what becomes of our understanding of consciousness it there exists a conscious state, such as the one I experienced, that has no hint of the first person?

151.                  Metzinger asks:  “what if pure awareness were a state of consciousness that did not resemble and that was not subjective either … not tied to an experiencing self?

152.                  Metsinger hypothesizes that MEP is generated in the upper brain-stream, where the mechanism for arousal is centered – in the ascend ingreticular activation system (ARAS) t o be precise.  This is the system that wakes us up, controls alertness, and activities that the cerebral cortex, preparing it to process incoming information. 

153.                  Consciousness thus begins as this wide-world aperture in which the world appears but with the arrival of memory, it soon contracts into a subjective point of view and, eventually, for better or worse, into a self.

154.                  Koch had gone through an experience that told him consciousness existed beyond the brain.

155.                  That is the path Koch has set out on: to explore the philosophy of idealism, which holds that the universe is made up of mind – something like Mind at Large.

156.                  Physicalism ultimately fails to explain the only thing we know to exist, Kastrup told him” which is experience.  Experience, of course is a synonym for consciousness.

157.                  Matter is an inference, Kastrup contends, and mind is a given.

158.                  Real things are things that exist for themselves and noy just for the observers.

159.                  And does mean that the world itself must be conscious in order to exist?

160.                  Kastrup is by no means the only thinker attempting to conceive of a world in which consciousness, rather than matter, is fundamental.

161.                  But then, most of what I thought I knew or took for granted, like the assumption that consciousness is a product of our brains and materialism will eventually explain everything, turned out to be unproven or wrong.

162.                  I was definitely inclined to that kind of narrowing of focus, turning the sotlight of intellect on what I regarded as a scientific or philosophical puzzle to be solved.  Hoping to heed the quiet voice, I’d explored a variety of more experiential or descriptive approaches: phenomenology, literature, psychedelics, hypnotism, and meditation – all ways of exploring consciousness that don’t necessarily treated as a problem.  But here was one last path to go down, one that didn’t even promise answers and actually made a virtue of not-knowing.

163.                  Of Joan Halifax: but the selflessness she manifestc in the conduct of her lifr is something to behold, a reminder that there is not only science but also ethics to being a human conscious human.  This too is a Buddhist principle – that overcoming one’s own small self should lead to greater compassion for others, and the suffering alleviated when we transcend the ego is not our own

164.                  Upaya is a factory for the destruction of selves, she told me.  I was curious to find out how it worked.

165.                  Its about being radically open to things just as they are, not grasping at or rejecting phenomena, but simply being present and at ese with moment-to-moment uncertainty and groundlessness and letting openness or not-knowing deconstruct our version of reality.  It is a method of non-method,  Just sitting upright – that apparently, all there is to zazen.

166.                  It hadn’t occurred to me that the ritual and silence could serve as tools to change consciousness and breach the hard shell of self.

167.                  The recipe was simpler (and much less appetizing) than I would have imagined: To transcend the self, force yourself to be alone with it long enough to get so bored and exhausted that you are happy to let it go. Poof!

168.                  The self might well be illusory, I decided, but no more so than color or any other construct of the mind.  Put another way, the self can be both illusory are real, or both.

169.                  On tripping and meditation: Something was happening to my sense of self, and it seemed to have everything to do with was happening to my sense of time.  I had never given mush thought to the relationship to self and time, but it explains a lot.  When self is deprived of time past (memory) and future (anticipation), it melts away.

170.                  But now, for longer and longer stretches’ I was simply here, being, with no thought of past or future.

171.                  The fact of consciousness loomed larger than the problem.  I wondered: “had I dropped in”?  Divested of meaning.  Was I having a minimal phenomenal experience?  Maybe, but only for brief stretches.  There were moments when all I experienced ws what Roshi Joan had called the “sense field,” a consciousness prior to language or concept of self.

172.                  For the first time, I could see – no, could feel – that the stars and I shared the same infinite space.

173.                  This moment of being fully, freshly present to the universe stopped me cold and made me wonder is all my hard thinking about consciousness had missed something crucial about it.  The more I strove to penetrate the mystery, focusing the increasingly narrow beam of my attention on what consciousness is and what it does and now it came to be the less of it I was actually experiencing – whatever it was. My time in the cave and, now, beneath this night sky showed me the price of my impatience with the mystery.

174.                  But as the days of solitude in these mountains had shown me, the wider circle of light, that numinous lantern of awareness, is still available to us, so long as we can break the spell of self and its distractions. … and let go of not knowing.

175.                  Consciousness is a miracle, truly, and remains the deepest of mysteries, yes, but it is also very simple it can fit into a sentence.  I open my eyes and a world appears.
