Stay Tuned with Preet | April 2, 2026 Episode: Do Plants Think, and Other Mysteries (with Michael Pollan)

Episode Overview

This episode features a wide-ranging conversation between host Preet Bharara and renowned author Michael Pollan, whose latest book—A World: A Journey Into Consciousness—dives into the mysteries of consciousness, from the scientific “hard problem” to the sentience of plants, the boundaries of AI, and the implications for what it means to be human. The discussion balances deep philosophical questions with accessible storytelling, touching on Pollan’s personal experiences with psychedelics, the nature of thought and feeling, and the expanding definitions of consciousness.

Key Discussion Points and Insights

1. The "Hard Problem" of Consciousness

[03:12 - 04:51]

• Definition & Significance: Consciousness is described as "subjective experience." The "hard problem" is understanding how matter (the brain) produces mind (the feeling of being 'you'). Other unsolved mysteries: why anything exists at all, and how life emerges from non-life.

  “If it’s like anything to be a bat…that creature is conscious.” —Michael Pollan ([03:34])

• Why isn’t everything automated? Consciousness seems needed when situations are unpredictable and solutions can’t be hardwired—especially in social contexts.

  “A lot of what our brain does is automated... Consciousness is kind of at the tip of the iceberg.” —Michael Pollan ([03:33])

2. The Mind Studying the Mind: The Paradox

[06:23 - 09:14]

• The struggle is because the only tool for studying consciousness is consciousness itself; there is no objective "view from nowhere."

  “You can’t get out of consciousness to study consciousness.” —Michael Pollan ([07:29])

• Science’s objectivity is itself a product of human consciousness, complicating pure study.

  “Even science, the whole enterprise of science, is a manifestation of human consciousness.” —Michael Pollan ([08:05])

3. The Weird Possibilities: Panpsychism and More

[09:16 - 10:53]

• Materialism vs. Alternatives: The materialist view (everything reduces to matter and energy) hasn’t cracked consciousness. Alternatives like panpsychism claim everything might have a “bit” of consciousness.

  “Consciousness does not emerge. It was always there. And it solves the problem, but kind of at an extravagant price...” —Michael Pollan ([09:16])

4. Inner Monologues: Diversity in Thought

[12:07 - 16:14]

• Not everyone thinks in words; many think in images or even in "unsymbolized thought" (neither words nor images).

  “Only a minority of people have an inner monologue that consists of words... the term [‘thought’] is an umbrella that covers many different styles of thinking.” —Michael Pollan ([15:12])

• Infants, pre-lingual humans, and probably animals have thoughts without words.

5. The Value and Trouble of Consciousness

[18:22 - 20:58]

• Curiosity is one motivator for studying consciousness, but also concern: our consciousness is “polluted”—invaded by social media, politics, incessant digital noise.

  “A lot of people feel like their heads are full of things they would rather not be there and that they’re being colonized.” —Michael Pollan ([18:45])

• Threats to the privacy and autonomy of consciousness are growing, with implications from politics to AI.

6. Psychedelics: Altering and Studying Consciousness

[20:26 - 24:30]

• Pollan recounts his psychedelic experiences, which defamiliarized his perception and led to insights—including the feeling that plants are conscious.

  “There’s a way in which psychedelic experience foregrounds consciousness... the windshield through which you’re normally seeing the world is smudged and you notice it for the first time.” —Michael Pollan ([21:06])

• Not all experiences or insights under psychedelics are “true,” but some can reveal valid aspects of mind and world: more sensory information, an emphasis on love, ego dissolution, etc.

7. Plant Sentience and Intelligence

[30:47 - 39:05]

• Plants exhibit astonishing behaviors when considered at their timescale (e.g., roots navigating mazes). Experiments show they can remember, communicate, and differentiate between kin and strangers.

  “The roots found the most direct path to the fertilizer. And if a mouse did this, we’d say it was intelligent.” —Michael Pollan ([32:05])

  “Plants can be rendered unconscious by the same anesthetics that render us unconscious…” —Michael Pollan ([37:29])

• The leading theory is plants use "bioelectric fields" to coordinate behaviors and “remember,” not neurons.

  “Neurons may be overrated... all cells can do what neurons do, they’re just slower.” —Michael Pollan ([35:17])

• Sentience vs. consciousness in plants: Pollan prefers the term "sentience" for plants, meaning basic awareness without self-reflective thought.

8. Ethical Implications: Eating Plants and Animals

[37:25 - 41:15]

• If plants are sentient, is it moral to eat them? Pollan discusses different scientific views: plants likely don’t “feel pain” as it’s not adaptive, and some even benefit from being eaten (e.g., fruit, grasses).

  “Pain would not be adaptive for a creature that can’t move away from it... they’re aware they’re being eaten, but they’re not feeling pain.” —Michael Pollan ([39:05])

• Moral consideration relies on evidence of suffering; rights and ethics are human constructions enabled by our consciousness.

9. Thoughts vs. Feelings: Where Does Consciousness Begin?

[38:39 - 45:49]

• Recent thinking suggests consciousness originates in bodily feelings, not just in high-level thoughts (cortex). The body's signals (e.g., hunger) come first; the brain decides what to do about them.

  “Feelings are how the body communicates with the brain... The brain exists to keep the body alive.” —Michael Pollan ([43:10])

• This has implications for whether entities without bodies (like AI) can have consciousness.

10. Can Artificial Intelligence Be Conscious?

[45:49 - 50:46]

• Pollan is skeptical that current AI can be conscious, mainly because it lacks a body and feelings, and the brain isn’t just a computer (no hardware/software divide).

  “The idea you could abstract consciousness like a software program and run it on another substrate is ridiculous.” —Michael Pollan ([46:56])

• The concept of granting moral rights to conscious AI is discussed, with concern about creating a new form of slavery or distraction from current moral issues.

  “If you want to lose control over these machines, give them rights, they’ll start suing us.” —Michael Pollan ([42:29]) “We are being pressed from two sides, and our sense of specialness is under challenge…this Copernican moment where we’ll have to figure out, who the hell are we? What makes us unique, what does it mean to be human?” —Michael Pollan ([51:02])

11. Art, AI, and the Qualitative Difference

[53:42 - 56:50]

• Pollan distinguishes between simulated and real art/emotion: real consciousness is likely necessary to create truly great art.

  “I think that you probably need consciousness to produce great poetry. I think you can simulate great poetry. Part of art is a collab.” —Michael Pollan ([54:21])

• The risk is that settling for simulation (“chatbot friends”) may impoverish what’s possible in real relationships and art.

  “When we accepted the emoji as a substitute for emotion, I think we gave up something.” —Michael Pollan ([56:44])

Notable Quotes & Memorable Moments

• On the limits of science:

  "Science is just another manifestation of human consciousness… there is no godlike perspective." — Michael Pollan ([08:05])

• On psychedelics and perception:

  "The plants in my garden were returning my gaze. They were fully conscious. Very benevolent by the way, nothing scary about it." — Michael Pollan ([22:44])

• On AI rights:

  “If you want to lose control over these machines, give them rights, they’ll start suing us.” — Michael Pollan ([42:29])

• On expanding concepts of sentience:

  “We are being pressed from two sides…a Copernican moment where we’ll have to figure out, who the hell are we?” — Michael Pollan ([51:02])

• On art, simulation, and loss:

  “When we accepted the emoji as a substitute for emotion, I think we gave up something.” — Michael Pollan ([56:44])

Tone & Style

The tone is inquisitive, rigorous but playful, and accessible. Preet frames big philosophical issues with humor and clear analogies, while Pollan brings depth and curiosity, sharing research, anecdotes, and the broader cultural implications. Memorable exchanges about “mindless mastery” in plants, the spectrum of consciousness, and the dangers of taking simulation for reality make complex topics relatable.
