Tiny People and the Death of Dualism

A recent article in BBC Future describes an odd and surprisingly consistent experience. People across cultures and centuries eat a particular mushroom and report seeing the same thing. Not colours. Not distortions. Not the usual psychedelic blur.

They see little people.

Sometimes playful, sometimes intrusive, these tiny figures are often aware of being watched. These are not vague impressions at the edge of vision but social encounters. Different individuals, different places, different times, and yet the same kind of experience.

The mushroom identified in the article is Lanmaoa asiatica, a fairly ordinary-looking species found in parts of East and Southeast Asia. Medicine already has a name for this kind of vision: lilliputian hallucinations. The term refers to seeing miniature people or animals, often vividly detailed and socially interactive. They are rare, but well documented, appearing in a small number of medical and chemical contexts.

Most hallucinations fragment experience. They blur, distort, or dissolve what is already there. These do something different. They introduce agents. They create scenes. They populate the world rather than scramble it. In other words, the mind does not fall apart. It builds.

This makes it difficult to hold on to a comforting picture of how minds work. We often imagine chemistry as something that adjusts experience from the outside, sharpening attention or dulling it, lifting mood or flattening it. The mind, in this picture, remains in charge. Chemistry merely interferes.

But that is not what seems to be happening here. A particular chemical interaction produces not just a change in intensity, but a change in content. Not a vague alteration, but a recognisable form of experience. Something repeatable and structured.

If that is true, then the mind begins to look less like a detached observer of the world and more like a system that generates experience under particular conditions. Change the conditions, and the experience changes with them.

This idea is unsettling, not because it reduces thought to chemistry, but because it challenges a deeply held intuition. We like to believe that while bodies obey physical laws, minds operate on a different plane. That meaning, imagination, and agency sit somewhere beyond matter.

It is easy to see why this view took hold. When we look inward, we do not encounter neurons or chemicals. We encounter thoughts, memories, intentions, doubts. The machinery that makes them possible stays out of sight. Experience feels immediate and self-contained.

For most of human history, there was no way to look any deeper, no reliable way to connect experience to its physical conditions. But substances like this mushroom act as probes. They do not simply disrupt consciousness. They reshape it in patterned ways. They show that what we experience depends intimately on biological conditions, even when the experience itself feels rich, meaningful, and real.

This does not tell us what consciousness ultimately is. It tells us something simpler and more uncomfortable: that minds are not separate from bodies in the way we often assume. That the boundary between physical cause and lived experience is thinner than we like to admit.

Once this is acknowledged, the implications spread outward.

Sleep loss, hunger, stress, illness, trauma. These are not external disturbances acting on an otherwise stable mind. They are changes to the system from which the mind emerges. They shape what can be noticed, remembered, learned, or sustained.

And yet our institutions often behave as if minds were detachable. As if attention were purely a matter of will. As if learning took place independently of bodies.

Education is especially prone to this mistake. Fatigue becomes laziness. Inattention becomes failure. Emotional volatility becomes a discipline problem. The body is treated as an inconvenience rather than a condition of thought. The mushroom makes this fiction harder to sustain.

None of this makes meaning disappear. Understanding how something is produced does not drain it of significance. Knowing how music works does not make it less moving. Understanding the physics of colour doesn’t make a sunset less beautiful. Knowing how thought arises does not make it less human.

What disappears is the illusion that the mind floats free of the material world.
