Episode Overview

In this episode, Dr. Sanjay Gupta explores the profound and perplexing topic of consciousness with renowned science writer Michael Pollan. Drawing on Pollan's new book, their discussion delves into the nature of consciousness, its potential definition, where it resides, and its presence in non-human entities—including plants and artificial intelligence. The episode unpacks historical, philosophical, and scientific perspectives and considers why consciousness remains one of the greatest mysteries of human experience.

Key Discussion Points & Insights

1. Why Write About Consciousness?

[02:34–04:56]

• Pollan's Motivation: Michael Pollan explains that, though he never planned to write about neuroscience, his research into psychedelic therapy ("How to Change Your Mind") and his meditation practice brought consciousness into sharp focus.
• Personal Psychedelic Experience: Pollan recounts an intense psilocybin trip where he felt plants in his garden were “fully conscious,” prompting questions about the boundaries between reality, hallucination, and brain-generated experience.
• Writing as Detective Work: He frames the book as a “detective story” born from trying to answer big, personal questions.

Notable Quote:
“It’s as if [psychedelics and meditation] smudge the windshield through which you normally look at the world... you’re not really aware of this incredible phenomenon that allows a world to appear to you.” — Michael Pollan [03:30]

---

2. Defining Consciousness

[04:56–06:47]

• Challenges in Definition: Pollan points out the paradox that consciousness is the thing we know most intimately, yet struggle most to define.
• Simple Definitions: Offers “awareness” and “experience” as foundational definitions—things that, for example, a toaster does not possess.
• Nagel’s Bat Test: Cites philosopher Thomas Nagel’s “What is it like to be a bat?” as a key philosophical example—if there’s something that it’s like to be, then the entity is conscious.

Notable Quote:
“It’s that quality of what-it-is-likeness... that there is a qualitative dimension to our experience, and that is consciousness.” — Michael Pollan [06:27]

---

3. Science’s Struggle and Consciousness as an "Unmapped Continent"

[06:47–08:05]

• Complexity in Mapping: Scientific reductionism (materialism) may not suffice to explain consciousness; some scientists now doubt it’s fully reducible to physical explanation.
• Mapped Descriptively, Not Physically: While psychology and the arts have mapped various aspects, the physical mapping of consciousness remains elusive.

---

4. The Brain’s Job: Life Regulation and Homeostasis

[08:05–10:31]

• Antonio Damasio’s Theory: Consciousness as “deliberate life regulation,” heavily tied to biological homeostasis (keeping the body alive, not the other way around).
• Feelings as Primary: Emotional states (e.g., hunger, shame, pride) arise in the brainstem and relate to homeostasis—not just physically but socially.
• Thoughts are Secondary: Feelings are “the inaugural act” of consciousness; rational thought comes later.

Notable Quote:
“Feelings are the inaugural act of consciousness—not thought. And thought comes later.” — Michael Pollan [10:22]

---

5. Plants, Sentience, and Flickers of Awareness in Nature

[10:31–13:48]

• Plant ‘Neurobiology’: Shares mind-bending research that plants display remarkably complex behaviors (adapting, communicating, solving problems).
• Sentience v. Awareness: Differentiates between simple environmental awareness in plants and richer forms of sentience/consciousness.
• Experiments Described:
  • Corn roots navigating mazes.
  • Plants recognizing kin and sharing resources.
  • Plants changing leaf shape to mimic their supports.
  • Roots detecting running water, possibly through sound.
• Challenges: While not entirely convinced of plant consciousness, Pollan leaves with deep respect for plant intelligence.

Notable Quote:
“They have 20 senses to our five or six. ...I came out of it with a lot more respect for plants.” — Michael Pollan [13:28]

---

6. Artificial Intelligence and the Turing Test

[15:14–17:36]

• AI as Consciousness Replication: The challenge of building AI that genuinely replicates consciousness, not just supercomputer computation.
• Turing Test Limitations: Current AI can pass the Turing Test, but mainly by parroting human discussions of consciousness. A more meaningful test would be to train AI without any exposure to the concept of consciousness and see if it develops similar ideas.

Notable Quote:
“Fooling us is not difficult.” — Michael Pollan [17:28]

---

7. Mortality, Feeling, and the Limits of AI Consciousness

[17:36–20:06]

• Embodiment and Suffering: Pollan emphasizes the necessity of bodily vulnerability and mortality in manifesting feelings—a prerequisite for human consciousness.
• Brain as Computer?: Expresses skepticism about the popular computer/brain metaphor; brains and computers differ fundamentally, particularly in how they process and embody experiences.

Notable Quote:
“Without bodies and mortality, and an ability to suffer, whether [AI] can really be conscious... I think these things are essential.” — Michael Pollan [18:23]
“Every experience rewires the brain... Brains are not interchangeable the way computers are.” — Michael Pollan [19:18]

---

8. Where Is Consciousness? Transmission vs. Generation

[20:06–21:47]

• Transmission Theories: Some philosophers and scientists speculate that the brain may act as a receiver for a field of consciousness, rather than generating it.
• Religious Parallels: Pollan observes that such ideas have overlap with religious concepts of the soul.

Notable Quote:
“I think there's a religious subtext to a lot of the discussion of consciousness. I think it is our secular version of the soul.” — Michael Pollan [21:47]

---

9. Practical and Philosophical Implications

[22:26–26:52]

• Clinical Implications: Advances in neuroscience (e.g., work by Christophe Koch) may soon allow us to detect consciousness in patients who appear unconscious, changing how medicine approaches care, prognosis, and ethics.
• The Book’s Call to Action: Pollan encourages defending and appreciating consciousness against technological forces that aim to capture and monetize our attention.
• Living with Mystery: Consciousness may always remain partly mysterious; some questions may never be answered in a finite human life, but that should motivate appreciation of our sentient experience.

Notable Quote:
“Consciousness is under threat from technology. ...They want to win our affection and attachment, so we spend more time on their platforms and less time within this wonderful space.” — Michael Pollan [23:53]
“We’re losing our ability to be bored. Right? Who’s bored anymore? There's always some way to fill that time and space.” — Michael Pollan [24:28]

---

10. Closing Reflections

[24:40–26:52]

• Consciousness remains mysterious but deeply personal.
• The ability to “be bored” and exist within our own awareness without constant digital distraction is important to protect.
• The episode closes with appreciation for the enduring enigma of consciousness and the value in defending our interior lives.

---

Memorable Quotes & Moments

• “Consciousness remains a mystery. Will it always? No. I think eventually we should figure it out. But it may take a different kind of science or a collaboration of science with other ways of knowing.” — Michael Pollan [23:06]
• “I still have a hard time defining it. But I know that I can't live without it. Fair. I need to have it as a human being. But I still don't fully understand its purpose.” — Dr. Sanjay Gupta [25:23]

Summary

This rich and wide-ranging conversation highlights the enduring mystery of consciousness, both in content and spirit. Michael Pollan, with Dr. Sanjay Gupta, examines scientific, philosophical, and personal perspectives—probing everything from plant sentience to the nature of AI, and the very practical medical implications of our understanding (or lack of it). The key message: cherish, protect, and remain curious about your own inner life, for it may be one of the most valuable (and vulnerable) aspects of being human.

Transcript

[Dr. Sanjay Gupta]

Welcome to Chasing Life. Today we've decided to take on one of the biggest topics, I think, in all of our lives. What is consciousness and where does it come from? In a minute, we're going to be joined by one of my favorite science writers, Michael Pollan, who's written a book about this. But I got to tell you, this is a topic I think about a lot. Consciousness. In fact, when I was in the operating room, having just read this book, I was talking to my fellow surgeons and residents about consciousness. That's the very heart of what we do as brain surgeons. Where does it reside in the brain? Does it reside in the brain? That would be dependent on really being able to define what consciousness is in the first place. Look, I'm a brain surgeon. I've spent decades of my life studying the brain, and yet I am still perpetually fascinated by. By the mystery of sentience. This conversation only deepened my appreciation for the gift of an inner life and also the interior monologue, the conversation that we continuously have with ourselves. Is that a conversation we're having with our own consciousness? I'm Dr. Sanjay Gupta, CNN's chief medical correspondent, and this is Chasing Life.

Wayfair Every style, every home. Okay, welcome back to Chasing Life.

[Michael Pollan]

Thanks so much for joining us.

[Dr. Sanjay Gupta]

I always really enjoy our conversations. I feel like we go in a lot of different directions. And I read your book. Congratulations on it. It's a great book. It seems like a different book for you. And, you know, I'm going back to Omnivore's Dilemma. And I'm just wondering, before we get into some of the substance of the book, just tell me about some of the background on deciding to write this book?

[Michael Pollan]

Yeah. It was never part of my life plan to write about consciousness or neuroscience. But as you know, I wrote a book called how to Change youe Mind about psychedelic therapy. And as part of the research for that book, I had a series of psychedelic experiences. I also became a meditator. And I think those two activities put consciousness front and center in your attention. It's as if they smudge the windshield through which you normally look at the world and which normally feels completely transparent. And you're not really aware of this incredible phenomenon that allows a world to appear to you. I mean, I had on one of the psilocybin trips, I was in my garden and the plants in my garden suddenly seemed wide awake, fully conscious, returning my gaze. They were. I know it sounds terrifying. No, they were. They knew I was their gardener. They were okay. They weren't going to attack me or anything.

[Dr. Sanjay Gupta]

And it wasn't a bad trip, so to speak.

[Michael Pollan]

It was a great trip. It felt terrific. I felt like I was among friends. So, you know, I didn't know how to credit that experience. And is there any informational value in that? And that is always a problem with psychedelic experience. People have powerful insights, but are they true or not? You're saying, what's real, what's not real? And what is my brain creating? And you realize, okay, your brain is developing these, is giving you these hallucinations. But then you wonder, well, is the brain giving me normal consciousness too? It just all seems like much less familiar. And so I just became really curious. And I found the best formula for a book is having some big question that occupies you and then writing the detective story of looking for answers.

[Dr. Sanjay Gupta]

I wrote this when I was reading your book. And this is, you know, I was trying to like summarize the book into a few big questions. A world appears, a journey into consciousness explores what consciousness is, who or what might possess it. And I want to come back to that and why it matters for how we live. I think people have a general idea that consciousness, something so integral to who we are, how we function, is important. But what is it? How do you define it as a starting point?

[Michael Pollan]

You know, there's a paradox here because it's incredibly simple. It's the thing we know better than anything else, that we are conscious. And it's the only thing we can be sure of. Everything else is an inference. Yet we struggle with the definition. So there are a couple kind of simple one word definitions. One is awareness, the fact we have awareness. Another is experience. We have experiences. Your toaster does not have experiences, and those are serviceable. There's also a famous. Thomas Nagel, the philosopher back the 70s, came up with a wonderful. I don't know if it's a definition exactly, but kind of a test. And that is in an essay called what is it like to be a bat?

[Dr. Sanjay Gupta]

Yes.

[Michael Pollan]

And his thesis is that obviously it's very different to be a bat, but we can kind of, you know, they use echolocation instead of vision to navigate the world. And they hang upside down a lot, so they couldn't be more different than we are. But we can kind of assume that it's like something to navigate the world through echolocation. So they're in all likelihood they're conscious. So it's that quality of what it is, likeness that there is a qualitative dimension to our experience, and that is consciousness.

[Dr. Sanjay Gupta]

Describing consciousness, as you did in the book, as an unmapped continent. So if you're on a journey, you're traversing planet Earth, let's say, and you find a continent that is unmapped, uncharted so far. Was there a surprising characteristic of this landmass, call it. When you started to explore consciousness, were there things about this that you did not expect?

[Michael Pollan]

Oh, yeah, Many things I did not accept. I was surprised at how difficult it is for a science. That's underlying our scientific enterprise is a metaphysics, and that is materialism, or what sometimes call physicalism. And this is the idea that all phenomenon can be reduced to these terms, the laws of physics say. Everyone has assumed that this would be true for consciousness. But the people who work on it, many of them are coming to doubt that. That it simply may not be reducible. But when you say unmapped continent, it isn't quite true. There's a lot about consciousness, descriptive information about consciousness. It's been mapped by the psychologists and Freud to some extent, and the artists, but it hasn't been mapped as a physical phenomenon.

[Dr. Sanjay Gupta]

I think it's early in the book you talk about Antonio Damasio.

[Michael Pollan]

Yeah.

[Dr. Sanjay Gupta]

Who calls consciousness something akin to deliberate life regulation. And also even talks about where it's located, which is the brain stem.

[Michael Pollan]

The brain stem, yeah.

[Dr. Sanjay Gupta]

Not the brain. But let's talk about the first part, this deliberate life regulation.

[Michael Pollan]

So the brain, as he reminded me, the brain exists to keep the body alive. It's not the other way around. Since we're so brain centric, we assume this body is here to move the brain where it needs to go and do what it needs and what the brain is doing. A Big part of what the brain is doing is monitoring the body and it is managing homeostasis. I mean, we all need to stay in a certain range in terms of blood gases and glucose and heart rate. I mean, there's all these, I mean, you know better than I do all these variables. And the brain is doing that a lot of the time. Feelings, in his view, arise when there's something amiss and that you have hunger, say, and the feeling begins in the brainstem. And his theory, and this is also Mark Soames theory, And only later does the cortex, which is the, you know, rational thought in the front of the brain, the evolutionarily most recent part, get involved. Like, well, we're going to go the restaurant, we'll take care of that, you know, and then pictures where you go and how you solve the problem. So this is life regulation and that is the brain's first job. I said to him, but we have a lot of feelings that aren't related to biological homeostasis. And he pointed out, though that we have other sort of homeostatic set points for our social standing, for example, and when we feel shame, we feel off. And we have a feeling that comes with it that we need to do something to restore our social standing. Ditto. Pride is a very positive feeling based on our social standing. So he thinks that homeostasis extends to these more psychological realms and the brain is charged with taking care of it. Basically his contribution to neuroscience has been to elevate the importance of feelings. Feelings are the inaugural act of consciousness, not thought. And thought comes later.

[Dr. Sanjay Gupta]

I guess I'm sort of building up to this point. I read this in the book, this idea that you spend time with these plant neurobiologists, I think that's what they're called, plant neurobiologists. And they're looking for flickers of awareness in plants. And it turns out that some forms of consciousness are more widely distributed in nature than we thought. You're right.

[Michael Pollan]

So first of all, plant neurobiologists, they're just trolling people like you by using that.

[Dr. Sanjay Gupta]

I was gonna say it was a great term. I wasn't sure exactly what it meant.

[Michael Pollan]

There are no neurons involved.

[Dr. Sanjay Gupta]

Okay.

[Michael Pollan]

But part of their argument is that you can get brain like behavior in things that don't have brains.

[Dr. Sanjay Gupta]

Is it brain like behavior to the point of awareness?

[Michael Pollan]

No, I wouldn't. Well, awareness in terms of they're sensitive to their environment. So that's a kind of, I guess that's a kind of very basic awareness. I think the term Sentience is useful here. It's a simpler form of consciousness. It doesn't have self consciousness or interiority. It is simply you register changes in your environment and you have a sense of good ones and bad ones and you take appropriate action based on that and that that may be universal in life and that, you know, single celled creatures may have, I mean, bacteria have chemotaxis, right? They know like, this molecule is good for me, this one's bad for me, and they act appropriately. Plants turn out to have a very complicated life. And I tell stories of these experiments where the root of a corn plant can navigate a maze just like a mouse and find a little packet of fertilizer buried somewhere in that maze. When two plants are in a pot together, if there were related, they'll share resources, and if they're not related, they'll compete. So they have some sense of, like, who they are. Some plants change their leaf shape based on. These are vines. If they're climbing up a plant that has a certain kind of shape, they will mimic it. So how do they see it to mimic it? We don't know. But they see in some way. They hear plants. Roots will seek out a pipe that water is running through that has no condensation on it at all, based perhaps on the noise, the sound. So they may hear plants hear the chomping of caterpillars on their leaves and then release certain chemicals. So now we could say all this is instinct, survival, Definitely survival. But the scientists I was talking to make the point that the world is so changeable and has so many novelties at any given time that evolution focuses on creating creatures that can solve problems, novel problems, rather than automating everything. And I found that persuasive. So I was, I didn't come out of this 100% persuaded that plants are sentient or conscious, but it certainly was mind bending to see what they could do. They have 20 senses to our five or six. It's kind of, it's, it's. Yeah, I came out of it with a lot more respect for plants.

[Dr. Sanjay Gupta]

I'm talking to one of my favorite science writers, Michael Pollan. His new book A World appears, A Journey into Consciousness. Fascinating read. We'll have much more after this break.

[Michael Ian Black]

Tab I got news for your ears, the podcast. I am your host, Michael Ian Black. If you look at the favorability ratings, in 20 years, Trump will be lower than Gacy because Trump destroyed so many more lives in Gacy. What's Casey's body count? 60. Yes, I'm, I mean, Trump blows up that many in a boat on the weekend.

[Dr. Sanjay Gupta]

That's right.

[Michael Ian Black]

That's what he's doing.

[Michael Pollan]

Everything's so hard to keep track of.

[Michael Ian Black]

That's why shows like have I Got News for your Exists.

[Dr. Sanjay Gupta]

That's right.

[Michael Pollan]

Oh, right to camera.

Have I Got News for your ears? Releases new episodes every Wednesday. Don't miss an episode. Follow us wherever you get your podcast.

[Carl Radke]

Hey, guys, I'm Carl Radke. You may know me from Bravo's summer house. I'm launching a new podcast called More Life. I want to learn from folks who are doing the work and from friends who've inspired me along the way. We'll talk the good, bad and the ugly, but most importantly, the healing, reinvention and self discovery. I definitely don't have it all figured out, but none of us really do. That's why we're here. Listen to More Life on Spotify, YouTube, or wherever you listen to podcasts. New episodes are out now.

[Dr. Sanjay Gupta]

I remember Michael Lee, whose name you might know. He's a Microsoft AI engineer. He said to me once, he said, don't think of AI as a supercomputer. Think of this as a technology that's trying to replicate human consciousness. So it's a much more audacious task and it's much more prone to errors as a result, the hallucinations that people talk about. But I still have a hard time getting my head around it. And I think it comes back to maybe the fundamental question that I started this interview with. How would you know? At what point do you say, okay, this is now crossed over into the territory of having acquired consciousness or even awareness as you describe it?

[Michael Pollan]

Well, you know, the classic test has been the Turing Test, right? Alan Turing, back in the 50s, said that we'll know that these, these machines are conscious or intelligence, he would use both terms, even though they're not identical, when they can fool the majority of intelligent humans in conversation with them. So the test is based on duplicity, which is interesting. And that.

[Dr. Sanjay Gupta]

The fooling part, you're saying?

[Michael Pollan]

Yeah, the fooling part. And that's been part of the deep DNA of computer science for a long time. This idea of the Turing Test, I don't think it's the best test, because these AIs, these chatbots, have been trained on the human conversation about consciousness. I mean, they're reading everything. They will read this book and fold it into their knowledge base. I think the real test would be to build an AI and take any discussion of consciousness out of its training materials and See if it could generate the same kind of conversation that these chatbots are generating now. That, I think, would be the test we're looking for. I don't know how you do that. If you just let them loose in the Internet, they're going to find this stuff. But you have to somehow create a training set that is completely free of all these terms we use. And maybe it's got to be free of fiction too. Maybe they can't read novels because you learn so much about consciousness in novels. I don't know. You'd have to design that very carefully. But that to me would be a more convincing case. Fooling us is not difficult.

[Dr. Sanjay Gupta]

Is mortality a necessary ingredient for consciousness?

[Michael Pollan]

So that's a great question. It may be, I think, that feelings are necessary to consciousness, as we were discussing earlier. And then you think about, well, what is a feeling? Or what does a feeling depend on? It depends on having a body. It depends on a kind of vulnerability, and it depends on an ability to suffer without these things which are tied to mortality, obviously, that, that if a threat to our bodily autonomy is serious enough, we can die. If you take away those things, feelings have no weight at all. They're just kind of more information. But for humans, they have a lot of weight. And that I think computers can't ever achieve. I think there are two big problems with this idea of conscious AI, at least based on the AIs we. We have and foresee. One is this idea that I don't know, without bodies and mortality, an ability to suffer, whether they can really be conscious. I mean, I think these things are essential. The other is it's based on a faulty metaphor that the brain is a kind of computer. Now, the brain does a lot of computation, it's true, and it has aspects of a computer. And neurons fire, and they're like transistors. They're either on or off. But there's a lot else going on in the brain. I don't have to tell you. I mean that there is a. You know, there are hormones and neurotransmitters and drugs. All these things can affect how neurons fire. And you also don't have a clear distinction between hardware and software in the brain. Every experience rewires the brain to some extent. Every memory is a physical thing in the brain. Brains are not interchangeable the way computers are because each brain is created by the life experience of that person. So this idea that consciousness is an algorithm or a software program that can run on a variety of different substrates is like, I don't Think it works? I think it's a faulty metaphor. There's a great quote that I read in Richard Lewonton, the great biologist, late biologist at Harvard. He said, the price of metaphor is. Is eternal vigilance. And I don't think we've been vigilant about this brain computer metaphor. I think it has lots of problems.

[Dr. Sanjay Gupta]

So just keeping with the computer metaphor for a second, even though we agree the brain is not a supercomputer, the brain is three and a half pounds of some of the most mysterious tissue in the universe. Is consciousness sort of a parallel operating system or is it integral to the brain, do you think? And I guess it gets at this point, Michael, that you've raised a couple times, where is it? Is it in the brain? After all the research you've done? What do you think?

[Michael Pollan]

Honestly, I don't know. I'll be totally frank about it. One of the scientists I talked to said, so what he's describing is what is sometimes called transmission theories, that there is a field of consciousness and what brains do, they're like TV receivers or radio receivers that they channel consciousness. Henri Bergson, the French philosopher, was the an exponent of this. Aldous Huxley, too, based on his psychedelic experiences in the Doors of Perception, said, clearly, I see consciousness outside my brain. I'm channeling it, and I'm getting only a measly little bit of it, and there's a lot more to get. And one of the insights he had is that there's a reducing valve that limits the amount of consciousness we take in from this field to just what we need to survive. But there's a whole lot more out there. But anyway, the scientist was telling me that the brain is still involved, but the brain is not generating consciousness, it's receiving consciousness. It's an interesting idea. You know, it seems kind of crazy to me, but, you know, who am I to say?

[Dr. Sanjay Gupta]

Sounds like religion.

[Michael Pollan]

It sounds a lot like religion. I. You know, I think there's a religious subtext to a lot of the discussion of consciousness. I think it is our secular version of the soul. But like. And I think part of our interest in it has to do with the fact that we have some residual longing for something called the soul. I mean, you know, think about souls. They're indestructible, right? They survive your death. I think there's a kind of a shadow behind consciousness around our mortality. I mean, that this is so weird and disconnected from the usual natural categories that maybe this survives.

[Dr. Sanjay Gupta]

You know, these are the hard questions. And frankly, you know, just even in preparation for interview, I spoke to some of my residents and people that I trained with as well, just to. And it's interesting. People have very disparate points of view. Even people who study the brain quite regularly. You know, going back to your other books, you do. It does feel like when I read your books, you have a thesis. I mean, you know, I mean, Omnivore's Dilemma, in some ways, that was a clarion call to individuals and to societies from a policy perspective to think about food differently with this book. Is there an argument, Is there a call to action? Is there something we should do differently after reading this book?

[Michael Pollan]

Yeah, I mean, the one thing. So it's true. I mean, Omnivore's Dilemma began with a question, too. What should I eat? And where did my food come from? And I was able to answer that question by the end of the book. In this case, no. I mean, it's a much bigger question. Hard to answer. Learned a lot along the way. But the ultimate explanation, it remains a mystery. Consciousness remains a mystery. Will it always? No. I think eventually we should figure it out. But it may take a different kind of science or a collaboration of science with other ways of knowing. I'm not sure exactly. The call to action is simply to appreciate what you have and defend it against all who would take it over, all who want to buy and sell your consciousness. I think that's the message. And I think that consciousness is under threat from technology. And technology, you know, the reason that they want to distract us, the reason they want to win our affection and attachment, is so we spend more time on their platforms and less time within this wonderful space.

[Dr. Sanjay Gupta]

So when you're in line at the

[Michael Pollan]

cafe, I resist the urge to pull out the phone and scroll. And I'm really trying to go back to that moment when I had to fill that space myself. And we're losing our ability to do that. We're losing our ability to be bored. Right. Who's bored anymore? There's always some way to fill that time and space.

[Dr. Sanjay Gupta]

It's interesting, Michael. I thought a lot about this book and thought about you. And if life were in some way potentially infinite, I think I would think about certain things very differently than I do.

[Michael Pollan]

What do you mean?

[Dr. Sanjay Gupta]

Life is finite.

[Michael Pollan]

Yeah.

[Dr. Sanjay Gupta]

So there's some questions in our lifetime that we're probably not going to answer. And then I get back at this idea that some things just are like consciousness seems to fall into that bucket to some extent. I still have a hard time defining it. But I know that I can't live without it. Fair. I need to have it as a human being. But I still don't fully understand its purpose. Awareness is obviously important, but there are people who are very much alive and very much unconscious at the same time.

[Michael Pollan]

Yes.

[Dr. Sanjay Gupta]

And I take care of those patients all the time. And it becomes challenging because they are alive. So consciousness is not directly associated with

[Michael Pollan]

life, and some small percentage of them may be.

[Dr. Sanjay Gupta]

That's where I think this argument probably goes, probably in terms of figuring it out. The fact that we can peer more deeply into the brain, into beings, humans in this case, that we think have some awareness and consciousness, even though they appear externally to be unconscious, I think is probably the next frontier.

[Michael Pollan]

And that's the practical implications of this work. It's interesting. Christophe Koch, who's a neuroscientist, who I profile in the book at some lane, he's a character who appears a few times. He's working on a technology to test those patients and determine if they are. If they have any consciousness at all, which will be very useful in medicine. Yeah.

[Dr. Sanjay Gupta]

I think we take care of patients a very specific way based on our perception that they are unconscious. And we make predictions of their lifespan, their remaining lifespan, based on whether or not they are conscious or not. So it could change a lot of. Are you. Are you already thinking about your next book?

[Michael Pollan]

No, I'm. I'm reveling in. I'm reveling in the fact that I don't have a book deadline at the moment, which is one of the sweeter feelings in life, I'm sure. I will write another book, but I don't know what it is yet.

[Dr. Sanjay Gupta]

Always a pleasure, sir.

[Michael Pollan]

Likewise, Sanjay. Always a pleasure to talk to you.

[Dr. Sanjay Gupta]

That was my conversation with Michael Pollan, author of A World Appears A Journey Into Consciousness.
