The relentless march of scientific progress has, for centuries, chipped away at humanity’s perceived centrality in the universe. From Copernicus displacing Earth from the cosmos’s center to Darwin demonstrating our shared ancestry with all life, and Freud suggesting our minds aren’t entirely our own, each revelation has delivered a humbling blow to human exceptionalism. Now, as artificial intelligence rapidly advances, a new challenge to our self-regard is emerging, one that author Michael Pollan dissects in his latest book, A World Appears. Pollan’s work suggests that the current fervor surrounding AI may be built on a fundamental misunderstanding of what it means to be conscious – and that the gap between human experience and machine capability may be far wider than many believe.
Pollan, known for his influential books on food and psychedelics – including The Omnivore’s Dilemma and How to Change Your Mind – consistently explores the boundaries between the self and the external world. His new book represents a logical extension of this inquiry, delving into the very nature of consciousness itself. He doesn’t offer easy answers, admitting upfront that the field is characterized by a bewildering array of competing theories. As Pollan writes, there are currently at least 106 hypotheses of consciousness, comprised of 22 physicalist accounts and a staggering 84 non-physicalist theories, a situation he wryly describes as “a pretty good indication that the field is flailing.”
This exploration isn’t merely academic. Pollan frames the debate around consciousness as crucial to understanding the limitations of artificial intelligence. The breathless promises of AI achieving human-level intelligence, he argues, often ignore the profound mystery of subjective experience – the “what We see like” to be alive, as philosopher Thomas Nagel famously put it. The core question, Pollan suggests, is whether consciousness can be replicated through computation, or if it represents something fundamentally different, something beyond the reach of algorithms and silicon chips.
The Elusive Nature of Feeling
A key argument in A World Appears centers on the primacy of feeling. Pollan contends that feeling isn’t simply a byproduct of computation, but a necessary precondition for consciousness. He highlights the work of neuroscientist Antonio Damasio, who believes that feeling has been historically undervalued in scientific study, perhaps due to societal biases. As Pollan notes, “It is one of the paradoxes of computer science that the ‘higher’ capabilities we once thought of as uniquely human—reason, language, intelligence—have proved easier for machines to master than the more elemental capabilities we share with animals, including feelings and emotions.”
This observation challenges the conventional wisdom that intelligence is simply a matter of processing power. AI excels at tasks requiring logic and calculation, but struggles with the nuanced, embodied experience of feeling. Pollan illustrates this point with a striking example: “A recent study demonstrated that a single cortical neuron can do everything an entire deep artificial neural network can.” This disparity, he suggests, casts doubt on the notion that simply scaling up computational power will unlock true artificial consciousness. OpenAI CEO Sam Altman, a leading figure in the AI revolution, faces a significant hurdle in bridging this gap.
From Plants to Self: A Journey Through Consciousness
Pollan structures his investigation of consciousness in four stages, moving from simpler to more complex forms. He begins with plants, initially considering them as representing a rudimentary level of awareness. However, he quickly discovers that even plants exhibit a surprising degree of sensory integration, processing information from more than twenty distinct senses, including all five of our own. He then moves to explore the role of feeling, thought – through a personal experiment in recording his stream of consciousness – and finally, the elusive concept of the self, contemplating its nature and impermanence.
This culminates in a deeply personal reflection, with Pollan meditating in a cave in Santa Fe, New Mexico, grappling with the insoluble nature of his quest. The book doesn’t offer definitive answers, but rather a thoughtful exploration of the questions themselves. Pollan’s approach is reminiscent of other works that tackle the complexities of consciousness, such as David Lodge’s Consciousness and the Novel and the early sections of John Searle’s Mind, though Pollan’s style is more accessible and less speculative.
AI and the Limits of Materialism
While A World Appears isn’t solely focused on artificial intelligence, Pollan skillfully uses the AI debate to illuminate the broader philosophical questions surrounding consciousness. He argues that the hype surrounding AI often stems from a deeper cultural anxiety – a decline in traditional belief systems and a yearning for transcendence. The promise of creating artificial consciousness, he suggests, is a modern-day equivalent of earlier utopian visions, like the conquest of Mars or the achievement of the technological singularity.
Pollan cautions against romanticizing the potential of AI, noting that the economic motivations driving its development often overshadow genuine scientific inquiry. He observes that the leaders of AI companies often reject humanism not because of scientific objections, but because workers are expensive. This economic reality, he suggests, is reflected in the increasingly close ties between big tech and right-wing politics, a relationship he characterizes as “simply more honest.” The pursuit of AI, in this view, isn’t about expanding human potential, but about maximizing profit and control.
Pollan’s book suggests that AI isn’t a new beginning, but an finish point – a confrontation with the inherent limitations of science and technology. It forces us to confront the question of what science and technology cannot do, and what aspects of human experience may remain forever beyond their grasp. This realization, while potentially unsettling, also offers a renewed appreciation for the mystery and wonder of being human. The book serves as a reminder that some questions may not have answers, and that the pursuit of those questions is, in itself, a profoundly meaningful endeavor.
As AI continues to evolve, and its impact on society deepens, Pollan’s work provides a crucial counterpoint to the prevailing narratives of technological inevitability. The next major development to watch will be the release of further research into the neurological basis of consciousness, expected from several leading universities in late 2026. A World Appears invites readers to engage in a critical conversation about the future of AI, and the future of humanity itself. Share your thoughts in the comments below.
