Can a Plant, a Chatbot, or Your Gut Be Conscious? With Michael Pollan
October 14, 2026
AI Summary
5 min readMichael Pollan’s latest book, A World Appears, began with a psychedelic experience that “smudged the windshield” of ordinary perception, making him suddenly aware of consciousness itself as a phenomenon. That defamiliarization set off a cascade of questions about what consciousness is, whether it requires a brain, and whether it could exist in plants, machines, or even the trillions of bacteria living in our own guts. In this live episode of Science of Perception Box, Pollan joins neuroscientists Heather Berlin and Christoph Koch to explore the boundaries of subjective experience, the limits of materialist science, and why he now believes we may be squandering our most precious gift.
The Hard Problem and Its Discontents
Philosopher David Chalmers famously distinguished between the “easy problems” of consciousness—mapping neural correlates to perception—and the “hard problem”: how physical matter gives rise to subjective experience. Pollan admits he finds the framing both persuasive and limiting. “I’m sensitive the way problems get framed in science,” he says, noting that Chalmers’ phrase has been so powerful it may be holding the field back. The alternative view, that consciousness is an illusion, strikes him as even less satisfactory. “I’ve never understood that,” he says flatly.

Show Notes
In this special live episode, journalist and bestselling author Michael Pollan explains how a psychedelic experience “smudged the windshield” of his consciousness and started the search behind his new book, A World Appears. He explains the difference between sentience and consciousness and shares some surprising plant research: corn that solves mazes, plants that recognize their relatives, and anesthetics that knock out a Venus flytrap. Pollan’s exploration of consciousness reveals a central idea of the Perception Box, a framework developed by Elizabeth R. Koch for understanding the forces within us that shape how we see ourselves, relate to others, and move through the world.
Dr. Heather Berlin is a neuroscientist, clinical psychologist, and Professor of Psychiatry and Neuroscience at the Icahn School of Medicine at Mount Sinai in New York City.
Dr. Christof Koch is Chief Scientist for the Tiny Blue Dot Foundation and the current Meritorious Investigator and former President of the Allen Institute for Brain Science.
