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.

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?"

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.

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.
