This is the third post of three in a series leading up to the 16th annual International Forum on Consciousness, taking place in Madison this May. Hosted by the BTC Institute, Promega and Usona Institute, the forum gathers scientists, philosophers, and practitioners from dozens of different fields to investigate the nature of the mind. This year’s theme, “Unspoken Intelligence,” explores forms of perception and knowing that fall outside conventional cognition.
In 1845, mathematician Urbain Le Verrier calculated where an unseen planet had to be based on irregularities in Uranus’s orbit, wrote a letter to an observatory telling them where to point their telescope, and Neptune was there. He found a planet without ever looking up.
This is what third-person inquiry looks like at its best: observe from the outside, measure what anyone with the right instruments can measure, build a model precise enough to predict what no one has seen yet. Then look. The history of science is full of such moments, equations pointing to phenomena that hadn’t been detected, particles that hadn’t been observed, forces that hadn’t been measured. The method works because it is ruthlessly disciplined about what counts as evidence. The observer is removed, the conditions controlled, and the measurement trusted.
That discipline is not a limitation. It is the engine of over four centuries of extraordinary results. It gave us germ theory, the structure of DNA, and the sequenced human genome. Every time something seemed to resist physical explanation, the method eventually found the mechanism and the method held. The winning streak was long enough that the assumption underneath it stopped looking like an assumption. Outside-in, third-person, measurable evidence stopped looking like one way of knowing. It started looking like the definition of knowing itself.
The assumption felt safe because it had earned its confidence. Digestion, heredity, mental illness, each had seemed to resist physical explanation until it didn’t. The pattern was consistent enough that the method felt inevitable rather than chosen.
Then science turned toward consciousness, and the winning streak entered dangerous territory.
Here is the problem, what philosopher David Chalmers named the “hard problem” of consciousness in 1995.
To understand what Chalmers meant, it helps to start with his own illustration. When you see red, something measurable happens. Light hits the retina. Signals travel along the optic nerve. Specific regions of the visual cortex activate in patterns that neuroscientists can map with increasing precision. All of that is, in principle, fully describable by the third-person, outside-in approach. Given enough time and instruments, you can trace the whole sequence.
What you cannot describe from the outside is what red looks like. The redness of red, that specific quality of experience that exists only in the moment of seeing it, is not in the neural map. No better scanner will find it there, because the felt quality of the experience isn’t a physical thing hiding in the data. It exists only from the inside. The outside measurement, however precise, cannot reach it.
Chalmers used “hard” deliberately, in contrast to what he called the “easy problems” of consciousness: how the brain integrates information, focuses attention, produces behavior. Those are genuinely difficult, but the outside-in approach knows how to go after them. The hard problem is different in kind. It’s the question that remains even after you’ve solved all of the “easy” ones: why does any of it feel like anything at all?
Think of it this way: everything the brain does could, in principle, happen without any felt experience attached. Processing, responding, behaving, all of it could run like a machine in the dark, with no one home. The question Chalmers is asking is why it doesn’t. Philosophers ask it this way: why is there something it’s like to be you, right now, reading this?
No amount of outside-in evidence, however precise, touches that question, not because the science is insufficient but because the method was specifically designed to exclude first-person data. That exclusion was the whole point. It’s what made the outside-in approach so powerful everywhere else.
With consciousness, the method’s central design decision runs into a question it wasn’t built to answer: how do you study first-person experience when your method was built to exclude first-person data?
In 1998, neuroscientist Christof Koch (who will be presenting at the Forum) and philosopher David Chalmers had been in dialogue about consciousness long enough to know they weren’t going to resolve their disagreement over dinner. So they did what serious people do with serious disagreements: they made a bet. Koch bet Chalmers a case of wine that by 2023, researchers would have identified a clear neural pattern that reliably corresponds to conscious experience. In plain terms: a way to look at brain activity and know, from the outside, whether consciousness is present, not by asking, not by inferring from behavior, but by reading the physical signature directly. The reliable outside-in marker that says: yes, this system is conscious or no, it isn’t.
Finding that marker wouldn’t solve the hard problem. It wouldn’t explain why the pattern feels like anything. But it would be genuinely consequential: a reliable way to detect consciousness from the outside, without having to ask. This knowledge could help answer questions that currently have no definitive answer: whether a patient in a vegetative state is experiencing anything, or whether an animal experiences its pain as suffering rather than only as a physical signal.
Twenty-five years later, on a conference stage in New York, Koch handed Chalmers a bottle of 1978 Madeira (after needing to reference an old interview transcript to remember the stakes). The tools had gotten extraordinary in those 25 years. The maps of neural activity were more detailed than anyone in 1998 could have imagined, but the neural signature Koch had bet on was still out of reach. Undeterred, Koch doubled the stakes on a brain marker of consciousness by 2048. Chalmers took the bet. “I hope I lose,” Chalmers said. “But I suspect I’ll win.” The conversation continues.
The more interesting story isn’t who won but what the work revealed. Over those 25 years, Koch’s thinking changed fundamentally. He didn’t stay the confident physicalist (someone who believes consciousness will ultimately be explained by physical processes) who made the original bet. He became one of the most prominent advocates for Integrated Information Theory, developed by neuroscientist Giulio Tononi at the University of Wisconsin-Madison, which proposes that consciousness isn’t something brains produce but something the universe has. He went from treating consciousness as the thing to be explained to treating it as the starting point everything else has to be built around. The limits he found with standard physicalism weren’t a reason to abandon third-person inquiry. They were a reason to find a framework that didn’t treat consciousness as a problem to be explained away.
IIT is a framework that, by taking consciousness as a given rather than a destination, arrives at the same premise many contemplative traditions began with: first-person experience isn’t an obstacle to understanding consciousness. It’s the starting point. While the methods are entirely different, the premise is the same.
The Koch/Chalmers story is recent and Western, but curiosity about the nature of the mind is as old as the mind itself. For much longer, Eastern contemplative traditions have used first-person inquiry, taking the opposite methodological path from the one Western science would later choose. Each practitioner is the experimenter, the instrument, and the subject.
Some of what they have found came from deliberate inquiry. Some came from simply paying close attention to experience over a long period of time, the way people do when they’re alive and present. They worked with exactly the kind of evidence the outside-in approach had excluded, treating first-person inquiry not as an alternative to rigor but as a different form of it.
Andrew Holecek, a Tibetan Buddhist teacher and author (who will be presenting at the Forum), is one practitioner working in exactly that way. He studies within a tradition that has used the hypnagogic state, the threshold between waking and sleep, as a laboratory for examining consciousness from the inside. The practice involves learning to remain aware as the waking mind dissolves, watching the mind dissolve rather than simply losing consciousness.
Holecek is one practitioner in a lineage that stretches back centuries, each generation learning the practice, refining it through experience, and transmitting what they found to the next. First-person inquiry isn’t the absence of methodology. When the experimenter, the instrument, and the subject are one, the methodology is the lineage itself: practitioners across generations doing the same practice, comparing what they find, refining what gets passed on. It’s not independent replication, but it’s not trying to be that either.
Neuroscience eventually applied its own methodology to similar territories, and when it turned its instruments toward meditation practices, it observed that sustained practice physically changes the brain. Richard Davidson’s work at the University of Wisconsin-Madison (minutes from where the Forum convenes this May) in collaboration with the Dalai Lama was among the first to document this rigorously. Using Western scientific measures, Davidson found that regions associated with attention, compassion, and emotional regulation are physically different in long-term meditators. That’s exactly what certain traditions had known first-hand for centuries. Two completely independent methods, separated by centuries and continents, using completely different instruments, converged on the same conclusion.
This isn’t Western science validating contemplative knowledge. The contemplative traditions didn’t need neuroscience to make their findings true. The convergence just made it visible from both sides.
When Western science and contemplative practice finally came into contact, some findings aligned. Much is still contested. The two methods don’t always produce neatly compatible findings. Where they diverge, that divergence doesn’t tell you which tradition was wrong. It may just mark what each method can and can’t reach. Consciousness may never turn out to be Neptune. Neptune was always the kind of thing the method could find.
Any convergence, or lack thereof, hasn’t solved the hard problem. What it does tell us is that both traditions are investigating the nature of consciousness, sometimes on intersecting paths. Both traditions have been working that territory seriously, on their own terms, for centuries. But only one has had institutional standing. The hard problem may be what finally changes that.
What the study of consciousness keeps exposing isn’t a gap in the science. It’s an assumption underneath it, that third-person, reproducible, measurable evidence is the only kind that counts. The contemplative traditions were never trying to produce that kind of evidence. Within their own systems, across generations of practitioners, they keep arriving at consistent findings about the structure of experience. These traditions that developed rigorous first-person methods over centuries may deserve more than a respectful nod.
First-person evidence isn’t something scientific instruments can map, for the same reason that mapping sound waves can’t tell you whether music is beautiful. You can measure frequency, amplitude, duration, every physical property with perfect precision. But beauty isn’t a property of the sound waves alone. It emerges in the relationship between the sound and the person hearing it, and it only exists when someone is listening. No improvement to the acoustic map can capture that. To understand music fully you need both: the map and the listener.
The map and the listener are finally in the same room. Come be part of the conversation. The 16th annual International Forum on Consciousness takes place May 21–22, 2026, in Madison, Wisconsin. Register here.
