So now that I’ve sufficiently documented my trials of existential doom and gloom in the first entry to this over-sharing trilogy, you may be wondering where I landed on everything.
Well, you’ll have to wait for our next issue to reach that exciting conclusion, true believer.
For now?
More questions!
The original inquiry that spawned my trip down the
proverbial rabbit hole was,
“Why do I feel like
this?”
And I tilted at that particular windmill for years as it led
me down a path of accusations, biological speculation, historical circumstance,
and personal perspective. After years of frustration and eventual stagnancy, I
realized I was asking the wrong question.
You see, during that time of interrogative obsession, I kept
coming across a word.
This word eventually refocused my pursuits and demanded
that I acknowledge it.
This word changed my cardinal question.
This word was:
CONSCIOUSNESS.
A word, a concept, I became obsessed with, yet still don’t
understand.
It’s a fundamental focus of philosophy and religion, of
learning and of life.
It managed to simultaneously truncate and deepen my inquiry.
Now I was asking,
“Why do I feel?”
So just what the hell is consciousness?
Honestly, I’m not going to be able to answer that for you.
However, I’m going to get my feet wet offering some thoughts
and hope that the tentacles of the leviathan don’t wrap around my ankles as I
do.

If you seek a definition to the word consciousness itself, you’ll typically receive multiple answers.
My MacBook’s dictionary offers up the following:
- The state of being awake and aware of one's surroundings.
- The awareness or perception of something by a person.
- The fact of awareness by the mind of itself and the world.
So although we having differing definitions that can be used
based upon intent of meaning and situational context, we still have a through-line:
Awareness.
So is consciousness simply awareness of the raw data in the
world around us?
Well that’s certainly a factor in and facet of
consciousness. The internal systems of the brain that receive and categorize
sensory input, allow us to control motor output, and selectively focus
attention are all important to a central and cohesive definition. But this all leaves out one important aspect:
Subjectivity.
Do our emotional, intellectual, and preferential reactions
to input define who we are?
Maybe I’m putting the yoke before the ox.
Maybe we should first ask:
Who are you?
I’m not just talking about a list of work experience, hobbies,
features, or even personal history.
I’m talking about your essence.
Your:
Mind.
Soul.
Ego.
Spirit.
Your very BEING.
What the hell is that?
A quintessential component of being human stems from our
individual (subjective) experience of the external (objective) world. No two people have ever experienced the same
life, no matter how similar their circumstances.
Philosopher Thomas Nagel said,
“…The fact that an
organism has conscious experience at all means… that there is something it is
like to be that organism…Fundamentally an organism has conscious mental states
if and only if there is something that it is like to be that organism.”
We all know that there is
something it is like to be a human, and dilated even further, something that
it’s like to be each individual human.
Our BEING is what defines
us, and our experience of the world implicates that BEING. ∞
Although we all possess,
or are seemingly derived from our shared experience of consciousness, we still
vary wildly within our interpretations and reactions for which consciousness
allows.
Neuroscientist and author Sam Harris said,
“Consciousness is what it’s
like to be you. If there’s an experiential
internal qualitative dimension to any physical system, then that is
consciousness."
So is that subjective experience (or soul,
spirit, etc.) simply a result of our brain’s physical systems?
Well, some people would argue that it’s not based in our biological
make-up at all, but is metaphysical and even divine in its origin. Actually, that’s been a foundational idea to
most of the world’s major religions.
Throughout antiquity, before the advent of the scientific revolution,
the mystery of life still captivated human inquiry. People still questioned
existence. And over geographical/temporal locations we
can review how our ancestors answered those fundamentally human questions.
The Bible gives us the lines:
“And the dust returns to the ground it came
from,
and the spirit returns to God who gave it.” [1]
and the spirit returns to God who gave it.” [1]
While the Quran states:
"And they ask you about the soul. Say,
"The soul is of the affair of my Lord." [2]
These texts (provided you’re taking a literal
interpretation) seem to adhere to the idea that the essence of a human is the
instilled quality of a deity.
“Know ye not that ye are the temple of God, and
that the Spirit of God dwelleth in you?” [3]
The idea is that our bodies are simply temporary
hosts for the divine, and our ability to experience comes from the
supernatural. However, the idea that our bodies and “souls” are two separate
entities is not unique to the Abrahamic canon.
Hindu scripture reads:
“As a person puts on new garments, giving up old ones, similarly, the
soul accepts new material bodies, giving up the old and useless ones.” [4]
Here we see the idea of the soul transcending the body within the
context of reincarnation. So although we have differing religious ideologies
surrounding the concept of spirit or the soul, we see a correlation with the
idea of a distinct separation of the mind and body.
We also see this idea arise in philosophy. 17th century French philosopher René Descartes held this
belief in no uncertain terms.
He wrote:
“Thus this self, that is to say the
soul, by which I am what I am, is entirely distinct from the body, and is even
more easily known; and even if the body were not there at all the soul would be
just what it is.”
Descartes’ presumptions have been
categorized under the umbrella philosophy known as Dualism. This philosophical
branch, succinctly summed up, promotes the idea that “the mental
and the physical—or mind and body or mind and brain—are, in some sense,
radically different kinds of thing.” [5]
The beginnings of this philosophy span back to ancient
Greece, where Plato made similar assertions to Descartes’ that the soul and
body were two completely separate entities. He thought that the soul was pure
intelligence and belonged in the metaphysical world of ideas, but the spirit
became confused when set inside the temporal form of the human body. His
protégé, Aristotle, believed that the two entities (physicality and soul) were
separate, but were inextricably linked to form the essence of a human.
These
are a few examples of antiquity’s attempt at explaining something that exists
in the vacuum of abstraction. It’s a thing trying to define itself from within,
and failing to see other possible conclusions, lands in the realm of the
supernatural.
Our ancestor's conclusions are understandable considering that modern science still hasn’t
landed anywhere closer to a consensus as to the origin of consciousness.
So what has modern science given us in terms of possibilities?
Quite a bit, as it turns out. Each theory with its faults and
detractors, and each with its own unique ideas. The process of science is that
of competing input meant to point out flaws in its predecessors and challengers
and with all participants working to break down the erroneous and collectively
build up the credible.

…Thanks, Gold Five. I needed that.
Ahem…So before we dive into a theory or two, we should address exactly
why the problem is so hard in the first place.
Actually, there is a theory postulated towards exactly that. It’s
titled (accurately enough) The Hard Problem of Consciousness.
Philosopher/scientist David Chalmers asks,
“Why is it that when our cognitive systems engage in visual and auditory information-processing, we have visual or auditory experience…? How can we explain why there is something it is like to entertain a mental image, or to experience an emotion? It is widely agreed that experience arises from a physical basis, but we have no good explanation of why and how it so arises.
“Why is it that when our cognitive systems engage in visual and auditory information-processing, we have visual or auditory experience…? How can we explain why there is something it is like to entertain a mental image, or to experience an emotion? It is widely agreed that experience arises from a physical basis, but we have no good explanation of why and how it so arises.
Why should physical
processing give rise to a rich inner life at all?” [6]
It’s the fundamental
question that science can’t seem to answer.
We have more or less
identified the parts of the brain in conjunction with how they receive
information, and even how they work together for complex information
processing, but that still doesn’t explain the experiential element. It would seem that we are
more than the sum of our parts.
“The hard problem is
hard…” Chalmers continues, “because it’s not a problem about the performance of
functions.”
What is our soul, in
scientific terms? Or where is it, in
anatomical terms?
That’s the crux. That’s the hard
part.
“What makes the hard
problem hard…is that it goes beyond
problems about the performance of functions…why is the performance of these functions accompanied by experience?
“
There are a few theories floating around that attend to this question
in physiological terms. An interesting
one is Graziano and Kastner’s
Attention Schema Theory, or AST. They attempted to tackle the problem from the
perspective of evolutionary biology. Their general thesis is that consciousness
is a direct result from evolved processes of attention.
Graziano said,
“ The brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and in the AST, consciousness is the ultimate result of that evolutionary sequence.” [7]
Graziano said,
“ The brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and in the AST, consciousness is the ultimate result of that evolutionary sequence.” [7]
So how exactly does an evolved process of attention give rise to
subjectivity?
At any given moment, we are bombarded with sensory input and that
input flow is constantly changing. You can’t possibly account for every
single piece of information coming in, so your brain has to prioritize content
based on an internal hierarchical system of importance.
“This process is called selective signal
enhancement,” Says Garziano, “without it,
a nervous system can do almost nothing.“
In our midbrains, we have a piece of hardware called the tectum. It
functions as a unifying coordinator for all the various parts of the brain that
take in different sensory inputs. When you need to focus all of your faculties
of attention on something, this is the guy that lines the troops up. And when
they are all inline, they are able to build an internal model of what you're
experiencing in the "external" world.
“An internal model is a simulation that…allows for
predictions and planning. The tectum’s internal model is a set of information
encoded in the complex pattern of activity of the neurons.”
All
animals have a tectum; but what separates us from most of the wild kingdom is
that we have developed a sizeable cerebral cortex as well.
What’s
the difference?
While
the tectum allows us to focus all our attention on something, it limits in that
it has to keep direct attention on it. The cortex allows for attention on
anything irrespective of proximity. You can think about something without
experiencing it directly, and make predictions about it based on the memories
of previous experiences. You can use your advanced faculties to process the
events happening and plan ahead by imagining different events occurring and how
you’ll respond to each imaginary scenario.
The
tectum deals with the actual, while the cortex can process the abstract.
This
abstraction that exists in our minds is what we identify as our “self”.
We have no physical sense of these complex
processes occurring, because it’s happening on the neural level.
To
put a pin on it:
“It has a physical basis, but that physical
basis lies in the microscopic details of neurons, synapses, and signals…It
depicts…attention in a physically incoherent way, as a non-physical essence.
And this, according to the theory, is the origin of consciousness.”
So
here we have a biological explanation (theoretically) for what’s traditionally
been attributed to the metaphysical.
Another
theory, one that doesn’t so much offer a biological explanation for the advent
of consciousness, as much as it promulgates an inextricable connection between
it and the existence of the universe itself, is called Biocentrism.
The
theory’s creator, Dr. Robert Lanza, says:
“The
universe rises from life, not the other way around.”
Biocentrism
draws heavily from quantum mechanics. In the quantum field, there is a very
famous (and often replicated) demonstration on the behavior of particles.
It’s called the Double-Slit Experiment.
Basically,
you have a wall-like barrier with two gaps (or slits) in it. You shoot
particles randomly at the barrier, and measure those that happen to go through
the slits by placing a wall beyond them. This backing wall has sensors that
measure where the particles hit if they happen to make it through a slit. Some
particles go through the right slit, some the left, and some hit the initial
barrier and make no mark on the measuring wall behind it at all.
The
odd thing is that when scientists would cease to observe the experiment, and
come back to check where the particle impacted the measuring wall, they would
see that there was a mark through both the left and the right side.
Lanza
explains the findings:
“It’s conclusively proven that if one “watches” a
subatomic particle or a bit of light pass through slits on a barrier, it
behaves like a particle and creates solid-looking hits behind the individual
slits on the final barrier that measures the impacts. Like a tiny bullet, it
logically passes through one or the other hole. But if the scientists do not
observe the trajectory of the particle, then it exhibits the behavior of waves
that allow it to pass through both holes at the same time.” (8)
The
gist of the experiment (which is much more in-depth and complicated than I’ve
covered here) is that the very act of our observation, or even our presence,
impacts the field of externality that we call “the world.” It supposes that
everything exists in kind of a limbo state of “wave probability” until an
observer comes along and forces the wave into a particle by simply being there.
Think
of a video game. When you turn your character around to look east, does
everything to the character’s west still exist?
No.
That virtual world is rendered around you as you move within it.
Well,
this theory presupposes a similar effect to the world we experience in real
life. It only exists insofar as we force it into existence. There isn’t the
separation of subjective observer and objective reality. It’s two sides of the
same coin.
Everything
hangs in the limbo of wave probability until our minds force those waves into
particles. We experience the world as we create it with the systems of our
minds. Nothing is really “out there”, as much as it’s being calculated and
computed “in here”.
“What
we perceive as reality is a process that involves our consciousness.”
This
theory is diametrically opposed to the religious and philosophical ideas that
supposed a dualistic nature to the universe and its inhabitants, and
although it does not directly offer us an explanation as to why or how
consciousness arises, it quietly pushes those questions aside as it asserts
that consciousness is not the bi-product of our existence, but the very means
through which everything exists.
The
theory that could render all these points moot is called Mysterianism, and it has the main thesis of WE CAN’T FIGURE THIS SHIT OUT.
Mysterianist
philosopher Colin McGinn pushes the idea that we haven’t come to understand
consciousness and we never will, because the systemic operations of our minds
are simply incapable of comprehending themselves.
McGinn
said, “The human mind conforms
to certain principles in forming concepts and beliefs and theories…and these
constrain the range of knowledge to which we have access. We cannot get beyond
the specific kinds of data and modes of inference that characterize our
knowledge-acquiring systems…” [9]
Our understanding of
minds and brains is different by its very nature.
Brains have objective
qualities we can see, measure, and verify, while our minds are subjective and
thereby limited by that subjectivity. We can see the measured changes in the
blood flow of a person’s brain using FMRI
technology, but we can’t record any empirical data on how a person feels when
they hear their favorite music.
McGinn’s hypothesis is “the search for philosophical knowledge would be
an attempt to do with our epistemic capacities what cannot be done with them.
Our minds would be to philosophical truth what our bodies are to flying:
wrongly designed and structured for the task in question.”
So where does all of this leave us?
Well, by the end of this, I feel just as confused
as I did before I started. But I feel better about my inability to understand
my own existential experience once I set it against the backdrop of human
history. Women and men smarter and more educated than I could ever hope to be
still struggle with and argue about what it all means. The field is so vast and
encompassing; that what I’ve written here is just a raindrop in the infinite
ocean of it all.
I’ve
juxtaposed a few ideas set in the framework of the humanities, but these ideas
transcend any attempt of a non-contextual framework. Seemingly, any point
argued in one religion has a rebuttal in another. Every branch of philosophy
has another branch built to why the first branch is wrong. Things overlap,
exceed each other, and lose themselves.
No
wonder I’m confused.
That
confusion seems to be the human condition.
I
realized that I’m far from alone in my confusion, and that realization is in
itself a form of the freedom I was looking for.
And
while I still have questions, I won’t continue down my path of inquiry with the
assumption that I’ll someday figure it all out.
I’ll
just stay curious.
And keep learning as I live.
