Beyond the Ghost in the Machine: Why Consciousness Research Is Outgrowing Dualism

Posted on 18.05.2026

For nearly four centuries, the Western conversation about the mind has been haunted by a single idea: that consciousness is something separate from the body. René Descartes called it res cogitans, the thinking thing — a non-physical substance somehow piloting the meat of the brain. The philosopher Gilbert Ryle later mocked the picture as "the ghost in the machine." And yet, as a small but growing chorus of philosophers, psychologists and neuroscientists are now arguing, that ghost is still quietly steering the research agenda — even among scientists who would swear they are committed materialists.

That is starting to change. From new critiques of the so-called "hard problem of consciousness" to embodied and enactive approaches in cognitive science, the field appears to be entering a phase where the inherited mind-body dualism is finally being put down. The implications for neuroscience — and for how the rest of us think about ourselves — are significant.

The dualist hangover

Dualism, as Verywell Mind explains, is the view that mind and body are fundamentally different kinds of thing. Descartes' substance dualism is the most famous version, but there are softer flavours — property dualism, for instance, which accepts that there is only physical stuff but insists that mental properties (the redness of red, the sting of a stubbed toe) are not reducible to it.

Most working scientists would say they reject all of this. The brain is an organ; minds are what brains do. Yet the framing persists. Whenever a neuroscientist asks how neural activity "gives rise to" experience, or how objective brain processes "produce" subjective feeling, they are tacitly setting up two categories — the physical and the phenomenal — and then puzzling over the bridge between them. That puzzle is what the philosopher David Chalmers famously christened the "hard problem of consciousness."

Is the hard problem actually a problem?

A provocative argument in Noema Magazine takes direct aim at this framing. Its title puts the case bluntly: there is no hard problem of consciousness. The claim is not that consciousness is trivial or already solved. It is that the "hardness" is an artefact of the dualistic vocabulary we use to describe it. If you start by carving the world into physical processes on one side and qualia on the other, you will of course find that one cannot be derived from the other — you built that gap in at the beginning.

This is a deflationary move with serious philosophical pedigree. It echoes Ryle's original complaint that the ghost-in-the-machine picture is a "category mistake" — treating the mind as a thing of the same type as the body, only spookier. The Conversation recently asked whether it is time to give up on consciousness as the ghost in the machine altogether — to stop searching for an inner experiencer who watches the show, and instead to ask what kind of activity "having an experience" actually is.

The embodied turn

If consciousness is not a ghostly extra ingredient, what is it? The most productive answer emerging from contemporary cognitive science is that consciousness is something a whole organism does, in concert with its body and its environment — not something a brain secretes in isolation.

This is the thrust of what the British Psychological Society recently summarised in an interview headlined with a striking line: "We need to think about the grounding of consciousness in a more expansive way." The suggestion is that the brain-bound, neuron-counting model — find the right network, measure the right oscillation, and consciousness pops out — has hit a wall precisely because it inherits the dualist assumption that experience is a private inner display generated by a single organ.

Embodied and enactive theorists argue instead that minds are extended: shaped by gut chemistry, hormonal cycles, posture, the affordances of the environment, the rhythms of social interaction. On this view, asking which neurons "cause" consciousness is a bit like asking which dancer causes the dance. The activity is the thing.

What this changes for neuroscience

For working neuroscientists, this is not just a semantic adjustment. It reshapes the research program in at least three concrete ways.

Different targets. Instead of hunting for a single "neural correlate of consciousness" — the holy grail of the past three decades — researchers are increasingly studying loops between brain, body and world: interoception (how the brain models the inside of the body), predictive processing, sensorimotor coupling.
Different baselines. If consciousness is grounded more expansively, then comparative work matters more. Octopuses with their distributed nervous systems, infants before language, patients in altered states, even potentially conscious AI systems — all become test cases rather than curiosities.
Different humility. Dropping the hard-problem framing does not mean claiming we have explained experience. It means accepting that "why is there something it is like to be me?" may not be a well-formed scientific question in the form Descartes' descendants inherited. The empirical questions that remain are still enormous.

An Australian stake in the debate

Australian readers have a particular reason to follow this shift. Some of the most influential contemporary work on consciousness — including Chalmers' own — has roots in Australian philosophy departments, and the country punches above its weight in philosophy of mind and cognitive science. The debate over whether the hard problem is real or a relic is, in part, a debate about a distinctively Australian intellectual export.

It also matters practically. How we conceive of consciousness shapes how we treat patients with disorders of consciousness, how we think about animal welfare in agriculture and research, how we draft laws on end-of-life care, and how we will eventually decide whether any artificial system deserves moral consideration. A dualist framing tends to push these questions toward all-or-nothing answers: either the ghost is in there or it isn't. An expansive, embodied framing invites a graded, biological view of mindedness — one that fits better with how medicine, ethics and ecology actually work.

Letting the ghost go

None of this means the mystery of experience is dissolved. People will still wonder, lying awake at night, why their inner life feels the way it does. But the philosophical mood is changing. The smartest current writing on the topic — from Noema's dismissal of the hard problem, to The Conversation's question about the ghost in the machine, to the British Psychological Society's call for a more expansive grounding — points in the same direction. The dualism inherited from the 17th century has done what useful conceptual scaffolding does: it framed a problem, generated a research tradition, and is now ready to be taken down so the building underneath can be properly examined.

Giving up the ghost is not a loss. It is a long-overdue maturation. The mind was never a separate thing hiding inside the body. It is what a body, embedded in a world, does when it is alive enough to notice.
