Episode #179 ... Why is consciousness something worth talking about?
35m 41s
In this episode of "Philosophize This," host Steven West launches a new series on contemporary philosophy of mind, aiming to equip listeners with a deep understanding of current debates about consciousness. He argues that while these topics may seem abstract, they underpin all human concerns—morality, relationships, and politics—because our assumptions about consciousness influence every decision. West emphasizes the necessity of combining philosophical conceptual analysis with scientific empirical research, noting that science describes the world while philosophy interprets it. Central to the discussion is the "hard problem of consciousness," a term coined by David Chalmers, which asks how subjective experiences (qualia) emerge from physical brain processes. West distinguishes between access consciousness (processing stimuli) and phenomenal consciousness (the feeling of experience), and explores thought experiments like philosophical zombies—beings that behave like humans but lack inner experience—to question whether behavior implies consciousness. He applies this to real-world issues: AI like GPT-4 may mimic humans without being conscious, and animals may have radically different experiences, as illustrated by blindsight and Nagel's bat example. West then imagines a society that prioritizes only human consciousness, showing how such a hierarchy could justify animal exploitation, ageism, and ableism, demonstrating the moral stakes. He concludes by previewing the next episode on panpsychism, the idea that consciousness might exist in all things, inviting listeners to consider how different theories shape our world.
Hello, everyone.
I'm Steven West.

Thanks for supporting the show on Patreon.
Thanks for contributing for the back catalog of the show
while 179 episodes now.
Pretty exciting.
And for 178 of those episodes,
this show has been talking about the history
of philosophical ideas that have gotten us up to this point.
And it's a good thing we spent that long, I think.
I think to be able to understand the world you live in,
it helps to understand the history that it emerged out of.
And for any of you that have listened
to all 178 episodes we've done so far,
you're going to have a pretty big advantage
in this next thought experiment the show's going to be running.
Because maybe it's time on this show
that we start applying all this philosophical education
we've gotten to the real life contemporary philosophical debates
that are going on right now.
I alluded last time to some upcoming episodes
on the philosophy surrounding artificial intelligence.
And while we'll certainly be talking, even today,
about artificial intelligence as part of our examples,
there's a sense in which, in my opinion,
understanding the full context of why people
are talking about AI so much these days
comes down to first understanding a lot of ancillary conversations
that are going on in the philosophy of mind right now.
Things like free will and determinism,
things like the problem of identity,
the problem of intentionality.
Not to mention one of the most mysterious questions
in the history of philosophy,
the one we're going to be talking about today,
talking about the questions that surround what's become known
as the hard problem of consciousness.
These are hands down some of the biggest questions
that are facing modern people.
And by the end of this little arc of the podcast,
I can't promise you that you'll have definitive answers
to all these questions.
But what I can promise you, I hope,
is that I'll try my hardest here to equip you as a listener
with an understanding of the state
of these philosophical debates that are going on
better than 99% of the people walking the face of the planet.
And I got to be honest here at the start of all this.
For a long time, I didn't really see the value
when talking about stuff like this.
Hopefully there's at least somebody out there that can relate
to how I used to feel.
The thinking was, who really sits around
and thinks about unanswered questions
in the philosophy of mind?
How does consciousness arise?
Are we free?
Or do we just seem to be free?
How does my mind relate to objects that are in the world?
Like I used to think if you're really sitting around
thinking about this stuff,
first thing you gotta do is write a thank you card.
Write a thank you card to the universe or God
or whatever it is you believe in,
thanking them for the fact that you got no real problems
to deal with in your life.
I mean, I used to think all this stuff
is ultimately just unverifiable speculation.
None of these arguments are settled issues by any means.
So you can actually spend your entire life
talking about these things for your intellectual amusement
with your intellectual friends
and never really get anywhere.
Just seemed pretty self-indulgent to me, I don't know.
I mean, on the surface, these seem like the kind of conversations
we've seen all throughout the history of philosophy,
where there's a lot of brilliant thinkers positioned
on all sides of an ongoing philosophical discussion.
And then most of those people
that spend their time talking about it
end up being totally wrong,
usually because of something
they never could have seen coming anyway.
But eventually, my curiosity got the better.
I mean, I had to ask the question,
why are so many people talking about this stuff right now?
Why are so many brilliant people
dedicating huge portions of the best years of their career
trying to find answers to these things?
Is it just for their intellectual amusement?
Is it just so they can drink cheap wine from trader Joe's
with their neckbeard friends and feel smart for a while?
Well, clearly not.
Clearly, there's another way to be thinking
about these conversations going on
in the philosophy of mind.
And I eventually realized that what that is
is that every further conversation
that we have about anything that matters to us as people
ultimately emerges out of the assumptions
that we're making about the nature of consciousness.
And then our understanding of what a human mind
is that emerges out of that.
For example, any conversation about morality,
even at the most basic hedonistic level
of avoiding pain and seeking pleasure.
Even that is grounded on us maximizing
certain subjective conscious experiences of the world
and moving away from others.
It extends to any conversation about relationships.
Relationships, you can make the case,
is just talking about the details
of how two or more conscious people are interacting.
Politics is just a strategy of how conscious beings
try to get what they want in relation
to other conscious beings.
What I'm saying is whether these questions have answers
that we've settled on or not,
and whether you realize that you're doing it or not.
You are bringing assumptions about the nature
of consciousness to bear that affect your thoughts
on everything.
And that's part of what I want to do on this series.
I want to talk about why these conversations
about the nature of consciousness are important.
Why something that's seemingly so theoretical
actually goes on to have huge impacts
on real people all around you.
How it affects not just your own personal moral policy
that you live your life by,
but our political policies as well.
I'll give examples of alternative timelines.
What would have happened if society adopted
a different set of precepts about the nature of consciousness?
How would that have potentially changed things?
How would the world look today?
And I'll do it while offering up
as many of these different theories
being discussed today as I can.
So you can not only be more self aware
of where you fall in the discussion,
but hopefully by the end of this,
you'll be able to understand
other people's positions better as well.
Now let's get into it.
And if I've convinced you at all
that learning more about these conversations
in the philosophy of mind is important,
one of the first questions you got to be asking
as a modern person after hearing that.
Certainly a question I was asking years ago
is if I want to know more about what consciousness is,
why wouldn't I just study science and the brain?
Why are philosophers weighing in on this stuff at all?
Just look at the last hundred years.
We've learned so much about the brain
just through advancements in the area of neuroscience.
I mean, in terms of understanding
how brain states are connected to mental states,
we've come so far that it's not surprising people out there
would think that there's no end to that progress in sight.
That if we just keep running these experiments,
if we keep learning as much as we can
about the physical neurochemical makeup of the brain,
that will eventually be able to understand
everything about subjective experience.
But then again, there's also plenty of examples
throughout the history of philosophy of people
that thought that studying things empirically
was eventually gonna lead to a total understanding of it,
only to be disappointed by how much other modes of analysis
factor into understanding something fully.
For example, psychology or linguistics
or sociology, there's a type of conceptual analysis
that philosophers do that's just outside the purview
of science, which is to say that the way
we conceptually organize things, oftentimes precedes
the scientist doing their work.
It gives them the assumptions they have to use
when doing their work.
Classic example of this just so you can understand
what I'm talking about, the philosopher John Locke.
He describes matter in the physical world
as having both primary and secondary qualities.
He says objects have primary qualities.
Those are things like size, shape, mass, density.
But then they also have secondary qualities,
things like color, texture, smell, or taste.
Now that is a way that philosophers chop up
and conceptually analyze the world prior to
any actual experiments that may be done by a scientist.
In other words, some people in these discussions going on
today think that it may be the case,
that the reason these conversations about consciousness
are so mysterious to us is because there's something wrong
about the way we're breaking down reality
at the root level of concepts, and that if only we shifted
something at that fundamental level,
everything else would start to make a lot more sense.
This is why philosophers and scientists
have to work together on this stuff these days.
Philosophers and scientists need each other.
Philosophers rethink reality at a conceptual level,
and then scientists run brilliant experiments
to get to the actual empirical data.
But while scientists can and often have to compartmentalize
themselves into their specialized field
to be able to do their work, philosophers can take a step back,
and they have the luxury of looking at all the discoveries
going on in psychology or linguistics or neuroscience,
and they can try to come up with the theories
to how all these different fields link together.
Science tells you what the world is.
Philosophy tells you how to interpret it.
Put another way, no matter how brilliant
of a neuroscientist you may be,
you will still always have to be doing philosophy
to be able to interpret the data that you're gathering.
Now, we'll talk about many examples of all of these,
but not before we get some clarity on what may be,
the most cringe question of them all.
I mean, if you think these discussions are cringe sometimes,
'cause there's no clear solution to arrive at,
then the most cringe-lord question of all of them
is this, what is consciousness?
What is it?
You can spend the rest of your life thinking about that question
and really not get much of anywhere.
And it wouldn't be your fault.
It truly is a modern mystery.
It's actually kind of exciting.
And maybe somebody smart listening to this
will be the one to solve it one day,
but philosophers and scientists so far are nowhere
near a clear definition on it.
One thing they do agree on, though, most of the time,
that's valuable for you to know
as someone I'm trying to equip with tools in this series,
is that they seem to at least agree
on which conversations we're currently having about it.
We may not know what consciousness is,
but we do know what we're talking about.
We're talking about a certain kind of subjective experience
that we all seem to have that is distinct
from other things going on in your mind right now
that are usually presumed to be going on at a lower level
of experience, whatever that means.
People sometimes talk about these two different levels
of consciousness as access consciousness on the one hand
versus phenomenal consciousness on the other.
So access consciousness is going to be that lower one.
Term first used by the philosopher scientist Ned Block.
Access consciousness is made up of the entire process
of all very familiar with the fact that you are a human mind
that's living in a universe.
You're taking in this external stimuli
from the world around you all the time,
and there's some complex process that's going on.
You're taking in these phenomena,
you're forming them into perceptions,
you're forming those perceptions into memories,
you're directing your attention in one place
or another that's important to you.
These things and more are all a part of what some people
call access consciousness.
It is the area of our conscious experience
that allows us to access information from the external world
that is then used by our cognitive systems.
[BLANK_AUDIO]
Again, neuroscience has been studying all those things I just mentioned, and neuroscientists
are pretty great at being able to point to correlations between states of the brain
and those mental processes.
They've obviously identified the specific parts of the brain that deal with memory, that
deal with perceptions, that deal with attention, and all that's fantastic.
But there still seems to be something else to our conscious experiences of reality that
lies outside of this access consciousness.
And it seems to be something that neuroscience hasn't quite figured out yet.
And that is, well, one way to put it, is that it feels like something to be me, that
I have a subjective experience that seems distinct from anything else that's going on
in my brain.
For example, the way scientists and philosophers often talk about it in these conversations,
they'll ask, "What does it feel like to see the redness of an apple?"
That's one of these people like to use a lot.
Can you describe that?
Picture trying to describe what it's like to see the color red to somebody that's never
seen color before, or to describe what chocolate tastes like to someone that's never tasted
chocolate.
How do you do that?
Well, the more you think about it, the more it starts to become a pretty tricky problem.
Because in one sense, it doesn't really seem like something you can just describe to
someone with words.
It's something you have to experience.
And then in another sense, if you wanted to try to explain it in purely scientific terms,
you know, if you wanted to try to break it down and understand all the components of
what's going on at the neurochemical level and then look at the atoms that make up the
apple or something, well, the atoms that make up the apple are not red.
It has something to do with the way your conscious experience filters reality that makes it
look red to you.
And then it's a totally different thing, entirely beyond whatever mental filtration system
you got going on to then have a subjective experience of redness that's on top of that.
Where part of it all is that there's a unified stream of you being a continuous self with
continuity to time, continuity to your identity.
And the billions of phenomena that come into your awareness are presented to you not
in their full complexity, but in a digested format that you seemingly are able to organize.
What is that?
Why do we even have something like that?
Some philosophers call this phenomenal consciousness.
Some call it subjective experience.
Some call these subjective experiences qualia.
That's the common word philosophers will use.
And some say that these qualia cannot ever be reducible to purely physical states of
the brain. The implication being when you say that is that to some philosophers, no matter
how advanced neuroscience ever gets, it will never be able to find the neuro correlates
of consciousness, they say, or it will never be able to find the specific states of the
brain that give rise to these subjective experiences.
Many different reasons philosophers give to this.
It could be that consciousness is something fundamentally different than the material world.
That it exists on a level similar to gravity and space time and therefore may not be something
we can even study empirically.
That theory starts to run into other problems, as we'll see.
It could be that consciousness is an illusion that it only seems to us like there's this
command center up in our heads where we exist because it's biologically useful for it
to be there.
That starts to run into other problems.
This whole exercise of trying to explain how we have subjective experiences that are not
themselves physical, but they seem to arise from purely physical states of matter in the
brain.
The more you think about it, the harder of a problem to solve you realize that is that
that's why it's often called the hard problem of consciousness, a term coined by a guy
named David Chalmers back in 1995.
When you wrote one of the books, basically everybody's going to be referencing in modern
conversations about consciousness, it's called the conscious mind.
The reason the hard problem of consciousness is a particularly hard problem is because
even if you do come up with an explanation for how conscious experiences are possible,
it always just creates different problems in other areas.
One example of this from the history of philosophy is when Descartes tries to solve a similar
problem back in the 1700s.
Now Descartes is trying to think about the nature of knowledge during his time, not the
nature of consciousness in the sense modern people are discussing it, but he runs into
a similar difficult problem that leads to some of the issues we're having today.
The problem in his time was how can you explain the connection between the mind which is clearly
non-physical to him and bodies that clearly are physical?
How do those two things communicate?
And the way he solves it at the time is by saying that mind and body are obviously two
completely different substances.
And that solves the problem, right?
There doesn't need to be a connection between them.
The mind explains subjective experiences without having to make reference to a physical
body.
Mind and body interact through some kind of Harry Potter level magic that's going on in
the pineal gland, he says.
What more do you want from an explanation?
Well, the problem is, Professor McGonagall isn't actually up in your pineal gland mediating
conscious experiences.
But if you accepted that answer as many did and you ran with the idea that you are essentially
a mind that is inhabiting a body somehow, that assumption changes the way you see yourself.
It changes the way you see other people.
You really can start to see yourself like you are a person sitting in a movie theater up
in your head looking out at the world through your eyes.
This is actually sometimes called the Cartesian theater after daycart.
This is a metaphor for how our mind and body interact.
And we just finished the episodes on Susan Sontag where she talks about how the metaphors
we use go on to have real unintended effects on our thinking down the line in ways we may
not immediately realize.
And that is very true when it comes to the assumptions we make about consciousness as
well.
For example, if everything you think and feel is ultimately up in your mind somewhere
and your body is just the vehicle, then it's a much easier leap for people to make metaphysically
that they are a soul that is inhabiting a body or that consciousness is something non-local
part of some larger network of consciousness that exists somewhere else.
In other words, the philosophy you choose can make certain things seem plausible that we
really have no reason to assume.
And to somebody too desperate to solve the hard problem of consciousness in today's
world that uses Cartesian dualism to do so, it might be inviting a lot of stuff into
what's reasonable down the line that they don't even realize they're inviting.
Now the good news is, in these conversations about consciousness that are going on today,
almost nobody starts from a place of Cartesian dualism.
But they all start from somewhere.
And that's the point, every one of these runs into problems, and any one of these theories
adopted too quickly could easily create similar problems for people to the mind-body dualism
of Descartes.
So we got to take these theories seriously, and we got to ask the question, if it's not
like Descartes thought that mind and body are two different substances, then where exactly
does this type of subjectivity emerge?
Where do the physical states of the brain turn into the seemingly unified stream of phenomenal
consciousness that we all experience?
There's a famous thought experiment in this area where we can get thinking about this
stuff, commonly known as the philosophical zombie thought experiment put forward by that
same guy we talked about before the philosopher David Chalmers.
The thought experiment goes like this, imagine somebody standing next to you, that from the
outside appears to be an exact copy of you.
This copy behaves exactly as you'd behave, it reacts to everything exactly how you'd react.
But the catch is to David Chalmers, that this copy is what he calls a zombie, meaning that
despite looking and acting just like you, it doesn't have any sort of internal subjective
experiences that go along with its behavior.
The zombie has no phenomenal feel as he says, there are no qualia in the mind of this zombie.
In other words, it doesn't feel like anything to be this zombie.
The follow-up question to this is simple, do you think that the existence of something
like this zombie is possible?
Is it possible for something to look entirely conscious from an outside perspective, but
not actually be feeling anything like we feel in a phenomenal stream of consciousness
where it feels like something to be me?
Or would any person, or zombie for that matter, that can have perceptions think for memories,
direct its attention and all that, would that creature necessarily be conscious, simply
because there's no other way to be able to do all those things without being conscious?
Another question is, could we have evolved without consciousness?
And if this seems like another one of those cringe questions, I can empathize with you.
I mean, on one level, this can seem like a totally unanswerable question at this point.
So why even waste your time on it?
Why waste your time talking about hypothetical zombies that don't actually exist?
Yeah, I guess zombies could exist in theory, okay?
And oh, I get it, I think.
How do I know that you're conscious, man, right?
How do I know that I'm not the only conscious person, you know, the classic philosopher
drum circle moment where everybody's making a bunch of noise and we're all supposed to
dance to it like it means something?
I get that.
But on another level, think of how important the answer to this question becomes when we
apply this to other potentially conscious minds.
Think of the direct moral implications in two areas that we deal with every day, in the
conscious experience of animals and the realm of animal rights, or the conscious experience
of something like chat GPT and the realm of artificial intelligence.
In both of those cases, the philosophical zombie of Chalmers starts to make a lot more sense.
Because if we don't have an answer to the question of when the type of conscious experience
that we have arises, then we don't know what point animals or AI need to be given certain
moral protections.
You know, seemingly from a moral perspective, what we're trying to protect is that subjective
experience of being a thing that is in conscious torment.
Things going on against our will and we don't like it.
We don't want other conscious beings to have to go through it either.
It's the state of consciousness that we're ultimately trying to protect there.
That's why nobody feels bad for a Roomba, you know, nobody feels bad for the vacuum cleaner
that slaves away in your house all day trying to keep it clean.
But then as these machines are made to be more and more like people, we always got to be
asking the question of what point does this thing become conscious?
Because that's when it would ostensibly feel like something to be that thing and that's
That's also where it can start to feel horrible to be that thing.
So it's interesting to examine.
In the case.
case of something like Chatchy PT and language models like that, barring very few exceptions,
there is nobody out there that thinks what it's doing now in version four is anything
like our experience of consciousness. It's an algorithm people say. It uses statistics
and pattern recognition to predict the next word in a sequence. It's not emulating human
intelligence. It's doing an impression of what an intelligent human sounds like. Now
some philosophers say that when people read what Chatchy PT is producing and are impressed
as to how close it's coming to being conscious, that most of that work is being done by
the reader. Most of that is the reader projecting their human experience onto the words it's
writing. That we have this natural tendency to humanize something that looks and sounds
so much like a human, kind of like the zombie. And that while Chatchy PT is certainly
an awesome piece of technology, and while the stock prices of tech companies and clicks
onto articles about AI and the imminent singularity, those definitely get a boost for sure
with this, but some philosophers would say it's not even close to doing what human beings
are doing at a conscious level. Then again, if it was conscious and it was way smarter than
us, then it may make us think that it's stupid so that we'd let it out of its black box.
Anyway, the zombie from the thought experiment before starts to become relevant here, because
maybe it's clear that right now, Chatchy PT and other iterations are not doing anything
that looks like consciousness, but if things keep progressing and you can eventually get
to a place where you can build a machine and it is indistinguishable from a human being,
much like the zombie. In the sense that it does everything a person does, it reacts the
same way and even says that it's conscious like a person does, does that make that machine
conscious at that point? There are philosophers who say that it does, that if we're talking
about something that's truly indistinguishable from a conscious person, if we're saying
that that is not conscious, what are we even talking about at that point? It just seems
like a false distinction. Susan Blackmore says it this way, she's paraphrasing a point
from the work of Daniel Dennett, but I just love the way that she puts it here. She
says, quote, "The idea is ridiculous," they claim, because any system that could walk,
talk, think, play games, choose what to wear or enjoy a good dinner would necessarily
be conscious. When people imagine a zombie, they cheat by not taking the definition seriously
enough," end quote. On that same point of emulating every single thing about the brain
and what it's doing and then wondering if the machine would be conscious at that point,
the philosopher Keith Frankish says, quote, "I think if you could really understand everything
the brain is doing, it's 80 billion neurons interconnected and goodness knows how many
billions of ways, supporting an unimaginably wide range of sensitivities and reactions,
including sensitivities to its own activity. If you could really imagine that in detail,
then you wouldn't feel that something was left out." If a machine could be built to emulate
all the functions of a conscious creature, would it, from a functionalist perspective, have
to be considered conscious? And more than that, would we know it if something ever got to
that point? Or is it more likely that something would look mostly conscious? And then we do
what we always do as humans, project our own experience onto the thing and assume that
it must feel the same way that we do? Enter the conversation about animal rights. Again,
it's easy to project our experience of reality onto the seemingly conscious experience of animals.
It's easy to imagine what it's like to be a frog. To imagine looking out of a frog's
eyes the same way that you look out of your eyes. I think to be a frog, it would just feel
a lot smaller. Maybe the world would look kind of yellow because I got yellow eyes. I'd
be sitting on a lily pad. I'd see a snake coming. And when it tries to get me, I just hop
away and go over to my other frog friends. But in reality, not only do you not know what
it's like to be a frog, you don't even know that it feels like something to be a frog.
This is one of the points explored in a classic paper that began this new era of conversations
about consciousness. The paper is called "What is it like to be a bat?" by Thomas Nagel.
And he picks bats, specifically because they're so different from human beings. They're nocturnal.
They fly around. They have very different diets than we do. They use echolocation to navigate
around in the world. And one of the points he's making in the paper is that we have no reason
to assume that they have any sort of phenomenal stream of consciousness that resembles ours,
or it feels like something to be a bat. That there are billion ways that animals could
have evolved to navigate their environments that have nothing to do with the type of consciousness
that we experience. More than that, if you combine this line of thinking with the existence
of something like blind sight, where I don't know if you saw this story, but it's interesting.
Years back, back in 1965, scientists were doing a study on the neuropsychology of vision
at the University of Cambridge. And part of the process is they had to remove the visual
cortex of a monkey named Helen. And obviously, after doing that, she was completely blind,
in terms of there being any sort of phenomenal awareness like we have as human beings.
But then one day, when the head scientist was out at a conference, one of the researchers
started playing with Helen and giving her treats. And as he kept giving her these treats,
I think it was a piece of apple. She strangely started to be able to know which hand the apple
was in. But she always seemed a little unsure of herself, he said later. Didn't quite know
why that was. Little later, she started to be able to identify flashing lights, fast-forward
to a couple years later, and she was able to navigate different obstacles all around
her in a room. I mean, there's a video of it on YouTube. It was as though she could see,
it is clear that she has an awareness of what's around her, but she's not seeing things
the same way that we're seeing things. So how did she do it? The thinking of the scientists
was that there are two main pathways where the eyes connect to the brain. One of them,
the usual one we think about, goes up to the cortex, which Helen had removed. And the
other is an ancient one that's descended from the visual system used by fish, frogs,
and reptiles. Seem what Helen was doing. They thought could it be that Helen was now
perceiving the world using this ancient type of navigational system, where she's able
to navigate and know that objects are in certain places. But she doesn't have a unified
visual stream of consciousness that we associate with being able to see. They called this
phenomenon blind sight. And since then, it's been well documented, not just in monkeys,
but in people. People that have brain damage where they can't see on one side of their
visual field, doctors will hold up shapes in their blind spot. And they can tell the
doctor what the shape is, but they don't really know how they know that it's that shape.
They just have a strong intuition about it and happen to be right. Point is, could it
be that our minds are receiving a ton of information at different levels that are not
all available to us in that conscious stream that we're familiar with where there's a self
and a conception of time, a conception of identity? Could it be that most of the information
we get, we are not immediately consciously aware of, but we're able to access it through
something like what we call intuition or instinct, that the self doesn't exist at this level
of processing. So it's mysterious to us as to where these intuitions are coming from.
But that ultimately, this is a possible explanation for how something can appear to
act conscious from the outside, but not actually be conscious like the zombie. It's easy
to see Helen navigating a room full of obstacles and to think that she must be having an experience
that's similar to the one that I'm having. And then it's easy to be selective, right?
Like you see an animal do something that if it was a person doing it, you'd instantly
say that it was cruel, like a bear that eats the babies of another bear. That kind of
stuff happens all the time. And when it does that, we don't hold the bear morally accountable
for it, because no, it's operating based on instinct. It can't possibly have a conception
of the damage that it's doing there. But then when a bear does something sweet, oh, well,
this must be one of the good bears. It just wants to play and make a friend. There
was a whole range of potential experiences that animals could be having. And none of them
by any means absolutely have to have the type of subjective experiences that we have included
in it. In the same way, an algorithm like GPT-4 is given a level of humaneness that it
only has because we're projecting it onto it when it's doing human-like things. Animals
could be a type of biological algorithm playing out where they perform complex biological
functions, but lack the subjective experience that we have. Maybe when I'm at the park and
I'm talking to a dog like it's a person being all nice to it, whoo, like it knows it's
a dog or something. Maybe that's like me being one of these dudes on the internet that
falls in love with chat GPT and then an update comes out and they feel like they just got
ghosted on a dating app. What if I'm doing a lot of work I don't realize I'm doing projecting
my humanity onto this thing that isn't human? Now, if any of this sounds to you like an
intellectual justification for creating a hierarchy of conscious experiences, that's exactly
what I'm doing. This is the potential cost of these conversations about consciousness.
People already create consciousness hierarchies based on almost nothing. How many people
will eat a fish, but they won't eat a chicken, or they eat chickens, but they don't eat a cow.
And people will cite real reasons why they think about consciousness in this way. And
part of this whole exercise we're doing is thinking about how society might play out
if we adopt different precepts about the nature of consciousness. So here's what I'm
going to do. Like a goofy looking podcaster pretending to be the ghost of Christmas future,
I'm going to try to show you a vision of what the world might look like if we all more
or less just accepted one day that phenomenal consciousness is only something that human
beings possess. What might happen if a society was centered around not the sanctity of life
anymore, but the sanctity of human consciousness? What would happen? Would everybody be unified
in that world? Would we all just hold hands together under the banner of consciousness?
Everybody's on team human now. Yeah, you know, forget all those petty external differences
that used to divide us, right? Right. Well, how about this, though? Would people in just
a more general sense be more interested in exploring their own consciousness? Maybe
they'd see it as a foundational aspect of who they are. So now it matters more. Would therapy
become more popular? Would more people become neuroscientists instead of theologians?
Would we teach how to navigate your own consciousness in schools? Could we have kinder gardeners
meditating at recess? All interesting things to consider. But what happens when society
it's a free pass to think of animals as biologically.
Algorithms that we don't have to consider the feelings of, does everything
non-conscious in this type of society just become a resource to improve the
state of conscious beings? The low-hanging fruit here is obvious. If animals are
algorithms, the same way that Chachy-P-T is an algorithm, then there was zero
reason to feel bad for using animals the same way you use Chachy-P-T to write
your resume. Of course you can eat animals in that society, of course you can
farm them, and of course you can do animal testing. What does it matter? More than
that though, why not use things that are not conscious, even for my own
amusement as a conscious being? Why not have amusement parks like SeaWorld, where
you got orcas and dolphins performing all day? If everyone in society accepted
that these are just conscious-looking biological algorithms, as long as we
have enough orcas, who cares? And even better than that, why not have monkeys
that ride around on motorcycles? That'd be pretty cool. Why not have inter-species
MMA matches? I mean, there's a lot of ideas you could come up with that may give
someone a pleasurable conscious experience if that's what matter to you the
most. Why not chop down all the trees in your backyard that are blocking your
view of the sunset? And again, if it's about the sanctity of consciousness and
not about the sanctity of life anymore, think about how that changes something
like the abortion debate in that society. Not that it solves anything, but
imagine if people were arguing about abortion rights and weren't trying to
determine where life begins, but where phenomenal consciousness begins. In that
world, you'd have to ask the question, is consciousness something that's
injected just into human life at conception, not into animal life, or is
consciousness something that's developed as the brain develops? Is consciousness
something where multiple departments of the brain eventually coalesce into
what we think of as a unified subjective experience with a self? And in the
case of abortion conversations in particular, if we're considering
consciousness as the primary thing, how about the conscious experience of the
woman that has to carry the baby to term? How about the conscious experience of
the future baby? See, because that's the thing. If a society was willing to
create a hierarchy based around the quality of conscious experiences where
animals are thought of to just be lower, there was almost zero chance that
isn't going to extend into consciousness hierarchies among the conscious
people. Because it's not just the nature of consciousness that can be turned
into a hierarchy. It's the nurture of consciousness as well. Setting aside the
possibility that in this hypothetical society, we'd ever come up with some sort
of standard of conscious experience, where depending on how well you
culturally match up with it in that world, that determines your level of
worth. Let's pretend we would never do something like that. How might that
change? Where as your cognitive capabilities decline, you're seen as less and
less important because your conscious experience is getting closer and closer
to that of an animal. But how about just aging in general? What if in this
society, after you reach a certain scientifically determined peak age of
conscious awareness, then the older you get and the lower scores you put up on
the yearly consciousness test you do when you get your physical, the less that
society sees you as being entitled to a seat at the table when it comes to
anything? People would have no reason in this society to feel bad for openly
discriminating against people for their age or disabilities. And you can imagine
what it might feel like being somebody there. If consciousness hierarchies like
this were just the accepted standard, you would feel the same way
discriminating against someone for their age as you feel right now telling a
kid that they can't drive a car. Look, I'm sorry, it just can't. It's not good
for the rest of us conscious people out here that are trying to survive. When
we set up these consciousness hierarchies, we have to understand the criteria
that we're using and what theories in the philosophy of mind we might be
bringing into it. Because if you're willing to set up a distinction between fish
and chickens in your own head, because one of them seems to have a degraded
conscious experience, then you have to ask the further questions there too. If a
human being had a degraded conscious experience because of brain damage or
whatever else, can we eat them at that point? Can we put them in little mazes
and use them for experiments testing how they react? Well, was it okay to do
with hell in the monkey? Is it okay to do with rats? Is it okay to keep animals
and zoos? Is it okay to have pets? These conversations are important to have. If
in these examples in this hypothetical society, you saw glimmers of how some
people out there actually do look at the world and they bring these points up
proudly in casual conversation. Then you must realize the relevance these
conversations about consciousness can have. The point is all of this started with
a hypothetical zombie and a thought experiment that to some could seem like a
total waste of time to even talk about. But here's a real world example of how
the inferences we make about the conscious states of other creatures go on to
have real effects on personal and public moral policy. At a certain point, like
all giant precepts that most people take for granted that guide their moral
decisions. At a certain point, if you're one of the unfortunate few who care
enough to listen to a podcast like this, you're going to have to accept the fact
that even though you don't have complete information about this stuff, you still
have to make a choice about which of these tentative theories you're going to
accept for now. And when you do, it is going to have impacts on the way you see
everything. Now, if accepting this type of behaviorism, where we can't tell if
something's conscious just because it behaves like something that's conscious,
if that's an exercise in imagining what if consciousness that seems like it may
be there is not actually there, then what if we flip that around? What if things
that don't appear to be conscious actually are? What if everything is conscious?
Why do some philosophers claim that pan-psychism, as it's called, may be the
most likely answer to the hard problem of consciousness? And how might society be
radically altered if we all decided one day that that's what we wanted to build
our societies around? That's at least how next episode will begin. Thank you to

Podcast Summary
Key Points:
The podcast introduces a new series applying historical philosophy to contemporary debates, focusing on the philosophy of mind and consciousness.
Understanding consciousness is foundational to all discussions—morality, relationships, politics—because assumptions about it shape our views on everything.
Philosophy and science must collaborate
The "hard problem of consciousness," coined by David Chalmers, asks how subjective experiences (qualia) arise from physical brain states, a mystery unresolved by neuroscience.
Key distinctions include "access consciousness" (processing external stimuli) versus "phenomenal consciousness" (subjective feeling), and the philosophical zombie thought experiment questions whether behavior can exist without inner experience.
Applications to AI (e.g., GPT-4) and animal rights highlight moral implications
Examples like blindsight and Thomas Nagel's "What is it like to be a bat?" show that conscious experience isn't guaranteed by complex behavior, challenging assumptions about other minds.
Hypothetical societies based on consciousness hierarchies (e.g., valuing only human consciousness) could lead to exploitation of animals, ageism, and ableism, showing real-world stakes.
The episode ends by teasing next topic
Summary:
In this episode of "Philosophize This," host Steven West launches a new series on contemporary philosophy of mind, aiming to equip listeners with a deep understanding of current debates about consciousness. He argues that while these topics may seem abstract, they underpin all human concerns—morality, relationships, and politics—because our assumptions about consciousness influence every decision. West emphasizes the necessity of combining philosophical conceptual analysis with scientific empirical research, noting that science describes the world while philosophy interprets it.
Central to the discussion is the "hard problem of consciousness," a term coined by David Chalmers, which asks how subjective experiences (qualia) emerge from physical brain processes. West distinguishes between access consciousness (processing stimuli) and phenomenal consciousness (the feeling of experience), and explores thought experiments like philosophical zombies—beings that behave like humans but lack inner experience—to question whether behavior implies consciousness. He applies this to real-world issues: AI like GPT-4 may mimic humans without being conscious, and animals may have radically different experiences, as illustrated by blindsight and Nagel's bat example.
West then imagines a society that prioritizes only human consciousness, showing how such a hierarchy could justify animal exploitation, ageism, and ableism, demonstrating the moral stakes. He concludes by previewing the next episode on panpsychism, the idea that consciousness might exist in all things, inviting listeners to consider how different theories shape our world.
FAQs
The hard problem of consciousness, coined by David Chalmers in 1995, is the challenge of explaining how subjective experiences (qualia) arise from physical brain states, such as why seeing red feels a certain way. It's considered hard because even complete scientific explanations of brain processes don't fully account for the felt quality of experience.
Access consciousness involves the lower-level processes of taking in external stimuli, forming perceptions, memories, and directing attention, which neuroscience can study. Phenomenal consciousness is the subjective, felt experience of being yourself, like what it feels like to see the redness of an apple, which is harder to explain scientifically.
Proposed by David Chalmers, it asks you to imagine a being that behaves identically to a conscious person but lacks any inner subjective experience (no qualia). The question is whether such a zombie is possible, which challenges our assumptions about when consciousness arises and has implications for AI and animal rights.
Philosophers provide conceptual analysis that precedes scientific work, rethinking how we break down reality, like John Locke's primary and secondary qualities. They interpret scientific data and link discoveries across fields like neuroscience, psychology, and linguistics, helping to frame the questions scientists investigate.
Blindsight is a phenomenon where people or animals with visual cortex damage can navigate and identify objects without conscious visual awareness, using an ancient visual pathway. It suggests that much information processing happens outside our conscious stream, raising questions about whether behavior alone indicates consciousness.
If we don't know when subjective experience arises, we can't determine when animals or AI need moral protections, like avoiding conscious torment. This leads to questions about projecting our humanity onto things like ChatGPT or animals, and whether consciousness hierarchies are justified.
