Summary
What This Article Is About
Evolutionary psychologist Nicholas Humphrey advances a bold and counterintuitive thesis: the human soul is neither a divine gift nor a product of genetics, but a cultural invention—one built upon the biological substrate of sentience and amplified into something sacred by the evolution of language approximately 200,000 years ago. Drawing on Descartes’s substance dualism, the philosophical tradition of the hard problem of consciousness, and his own theory of sensory experience, Humphrey argues that the soul is best understood as a kind of culturally endorsed identity document, analogous to a passport, that assigns each human being profound significance, dignity, and moral standing within what he calls the “soul niche.”
Humphrey then turns to illusionism—the theory that conscious experience consists not of mysterious non-physical properties, but of the brain’s representational account of its own activity—as the most promising scientific framework for understanding consciousness. Far from making the soul disappear, illusionism rehabilitates it: if sensations are a form of self-portrait that the mind paints of its own doings, then the conscious self is real as an imagining, just as a mathematical idea is real without being made of matter. Humphrey ends by invoking Carl Jung’s encounter with the Sumerian god Izdubar, arguing that recognizing something as imaginary does not diminish its power—it may, in fact, be the very source of its extraordinary vitality.
Key Points
Main Takeaways
The Soul Is a Cultural Invention
Neither divinely granted nor genetically encoded, the soul is a cultural construct built upon sentience and elevated by language—a shared, adaptive fiction that transforms mere consciousness into sacred personhood.
The Soul as Passport
Humphrey argues the soul functions like a cultural passport—a community-endorsed guarantee of spiritual identity and moral significance that elevates each person’s status in their own and others’ eyes.
Sensation Is a Self-Portrait
Drawing on his theory of “redding,” Humphrey argues that conscious experience is not a passive readout of the world but an active, internalised bodily response that the brain monitors through feedback—making each sensation a self-portrait, not a photograph.
Illusionism Rehabilitates the Soul
Illusionism holds that consciousness is a set of mental representations rather than a mysterious non-physical substance. This does not eliminate the self—it relocates it to the domain of the imaginary, where it is real but not material, like a number or a work of art.
The Soul Niche as Adaptive Environment
Humphrey coins the “soul niche” to describe the social and psychological environment—built on mutual recognition of consciousness and personhood—to which humans have become evolutionarily adapted, in the same way trout are adapted to rivers.
The Imaginary Can Be Salvific
Via Jung’s story of Izdubar, Humphrey argues that recognizing something as a product of imagination does not destroy its power—declaring the soul a cultural fiction may be what saves it from the corrosive force of reductive scientific explanation.

Breaking Down the Elements
Main Idea
The Soul Is Real Precisely Because It Is Invented
Humphrey’s central and most provocative claim is that the soul’s cultural, constructed nature does not make it less real or less important—it makes it more so. Just as a passport derives its power not from being a natural object but from a collective agreement to treat it as authoritative, the soul derives its immense psychological and social force from the shared human decision to treat sentient beings as sacred. The essay argues this collective self-elevation was one of the most consequential evolutionary developments in human history.
Purpose
To Reconcile Science with the Felt Reality of the Soul
Humphrey writes with a dual audience in mind: philosophers and scientists who dismiss the soul as superstition, and ordinary readers who intuitively feel their own consciousness is something remarkable. His purpose is to show that both are right—and that the tension between them dissolves once we understand the soul as a culturally constructed amplification of biological sentience, and consciousness as an imagining that is none the less genuinely real.
Structure
Parable → Historical Survey → Philosophical Theory → Evolutionary Argument → Mythic Resolution
The essay opens with Anatole France’s comic parable of baptised penguins to frame the question of what qualifies a being for a soul. It then moves through Descartes’s dualism, Diderot’s skepticism, Darwin’s ambivalence, and the modern hard problem before advancing Humphrey’s own theories of the soul niche and illusionism. It concludes with Carl Jung’s myth of Izdubar—a narrative that mirrors the essay’s own argument that acknowledging the imaginary origin of something can be its salvation rather than its undoing.
Tone
Intimate, Erudite & Quietly Audacious
Humphrey addresses the reader directly (“your soul,” “you live there, you know”), creating unusual intimacy for a philosophical essay. He deploys wit and irony when challenging Diderot and Descartes, but sustains throughout a tone of genuine philosophical seriousness. The essay is audacious in scope—moving from penguins to Jung to neuroscience to evolutionary theory within a few thousand words—yet never feels rushed, because the second-person register keeps it grounded in the reader’s own felt experience.

In evolutionary theory, “functionally extravagant” means exceeding what natural selection would have strictly required for survival—a trait that goes beyond its immediate adaptive purpose, as Humphrey argues consciousness does.
“Is consciousness functionally extravagant: an answer to no real problem?”
In a way that involves propositional attitudes—mental states like beliefs, desires, or intentions that can be expressed as statements (“I believe that X is red”)—rather than involving raw, non-conceptual sensory data.
“we have only to explain how the brain situates a person, propositionally, as the holder of a certain kind of belief”
Formally approved, endorsed, or given authority by a recognised group or institution; here, “culturally sanctioned” means the soul is authorised and upheld by the collective norms and beliefs of a community.
“Your soul is a kind of culturally sanctioned guarantee of your spiritual identity and rights”
In a way that is harmful to survival or functioning; a maladaptive behaviour or belief is one that reduces an organism’s ability to cope successfully with its environment, the opposite of an adaptive response.
“you are at risk of behaving maladaptively”
To incorrectly treat two distinct concepts or things as identical or interchangeable, thereby obscuring an important difference between them.
“We tend to conflate ‘illusory’ with ‘false’, and ‘imagined’ with ‘imaginary'”
Something invented or imagined rather than real; a product of pure fantasy. Humphrey deliberately questions whether this term is as dismissive as it seems, arguing that imaginary things can have profound real-world significance.
“But why call it a figment? When such wealth makes its home in such poverty, it’s a marvel of marvels.”

1According to Humphrey, illusionism implies that the conscious self does not really exist, because sensations are merely representations rather than genuine features of reality.
2Humphrey criticises Diderot’s pocket-watch analogy primarily because it fails to account for which of the following?
3Click the sentence that most directly explains why illusionism makes the hard problem of consciousness easier to solve, according to Humphrey.
4Evaluate whether each of the following statements about the article’s philosophical claims is supported by the text.
Humphrey argues that Descartes was entirely wrong in his view of consciousness, and that modern science has fully refuted substance dualism.
According to Humphrey, the crucial catalyst that transformed mere sentience into the human soul was the evolution of language approximately 200,000 years ago.
Humphrey argues that physics does not account for everything, including ideas such as prime numbers, justice, or Cubism—and that at best it sets the preconditions for these ideas to arise in minds.

5Based on Humphrey’s overall argument, what can we infer he would say about a future artificial intelligence that processes information and generates behavioural outputs indistinguishable from those of a human being, but has never been embedded in a human social community that attributes a soul to it?
FAQ
Frequently Asked Questions
The soul niche is more specific than sociality. Humphrey uses the ecological concept of a niche—the environment a species is adapted to and where it flourishes—to describe the distinctively human social world structured around mutual recognition of consciousness and sacred personhood. It is not just that humans live in groups, but that they inhabit a shared imaginative space where every person is assumed to be a phenomenally conscious, morally significant, free-willed individual. This framework transforms social interaction at every level, from ethics to law to art.
“Redding” is Humphrey’s term for the brain’s active, expressive response to sensory input—rather than passively registering a wavelength, the brain mounts an internalised bodily response that expresses what’s happening and how it feels. A feedback loop then generates self-awareness of this response, constituting consciousness. This model supports his soul argument by showing that each person’s sensations are genuinely private and biometrically unique, giving the phenomenal self the individuality and irreplaceability that the soul concept requires.
Jung’s Izdubar is a god-king who weakens and nearly dies when confronted with rational scientific explanations, and is saved only when he accepts that he exists in the imaginary world. Humphrey uses this as a narrative mirror for his own thesis: the soul, confronted with reductive science, is not destroyed if it acknowledges its status as a cultural imagining. Ending mythologically rather than scientifically enacts the essay’s central claim that imaginative and rational ways of knowing are not rivals but complements in understanding what consciousness is.

Nicholas Humphrey is an emeritus professor of psychology at the London School of Economics and one of the most influential evolutionary psychologists working on consciousness. He is the author of Sentience (2022) and Soul Dust (2011), among other works, and is known for his original theory that consciousness evolved not primarily to process information but to generate a sense of the self’s own existence—a theory that feeds directly into the illusionism and soul-niche framework developed in this essay. His work bridges evolutionary biology, philosophy of mind, and anthropology.
