David Chalmers on why consciousness is science's greatest unsolved problem: Science has mapped subatomic particles, distant stars, the chemistry of life yet it remains almost completely silent on the one thing we know most directly: our own conscious experience. In a rare early interview, philosopher David Chalmers explains why:... "Consciousness is at once the most familiar thing in the world and the most mysterious. Consciousness is what we start with when it comes to knowing the world. I know that I exist. I know that I'm conscious. Everything else is secondary." And yet, despite this intimacy, consciousness sticks out like a sore thumb in the scientific picture. Chalmers points to a deep irony: science has made extraordinary progress on phenomena that are extraordinarily remote: subatomic particles, distant galaxies, the molecular machinery of biology while making almost no progress on the one thing closest to us. Why? Because science, by design, eliminates the subjective. "To do proper science, you have to be objective. You have to eliminate anything subjective from the picture." He uses heat as the perfect example. Physics gives us a complete account of heat molecules in motion, energy transfer, temperature gradients. It explains every objective aspect of the phenomenon. But it never explains what hotness actually feels like. "Science doesn't actually give a theory of the conscious feeling of hotness." This is what Chalmers calls the Hard Problem of Consciousness. You can trace every neural signal from your heat sensor along your nerves into your brain and still have explained nothing about the subjective experience of feeling warm. As interviewer Jeffrey Mishlove puts it: you can't even do science without a conscious mind to observe, interpret, and make meaning of data. Consciousness is the precondition for science itself and yet science has no framework to account for it. Chalmers' conclusion is striking: The methods of science may need to be expanded. Consciousness might not be something science explains away. It might be something science has to learn to start with.show more

Consciousness in all its varieties mystifies me - but not the so-called Hard Problem, which is most likely an artifact of bad metaphysics. Critically, we've no evidence that the intrinsic nature of the world's fundamental quantum fields differs inside and outside the head. If so, then the "fire" in the equations, the essence of the physical, is experiential. What makes animal minds / nervous systems special _isn't_ consciousness per se, but rather its phenomenal binding into virtual world-simulations ("perception").

From a strict physicalist perspective grounded in quantum field theory (QFT), there is no ontological distinction between subjective experience and objective reality. QFT posits a single, unified local field as the exhaustive ontology: excitations and dynamics constitute everything. The categories of "subjective" and "objective" are phenomenological constructs that emerge within certain field configurations, particularly those realizing complex, self-referential information processing. The notion of "consciousness" itself, if it is to remain within physicalism, must be realized by that same local field, the only ontic reality physics accesses. Qualia and phenomenal character are how specific local states are from the inside; no extra ingredient or bridging law is required. The hard problem presupposes a separate objective substrate that must somehow "produce" experience, an assumption QFT does not support. For the consistent physical realist, the field is exhaustive: experience just is physics. Problem solved.

Chalmers is a physicalist who is worried that materialism isn't convincing when it comes to subjectivity & interiority, but subjectivity is not 'consciousness' any more than is objectivity; consciousness is ontological lucidity & ground zero, nothing else. Also if you are a physicalist why not go with the tenured flow & declare subjectivity an epiphenomenal outcome of brain activity? Plenty of others have already done so. 'The Conscious Mind' has not advanced our insight into consciousness one bit.

@BigBrainPhiloso If you are interested in the root cause of the hard problem of consciousness, it exists because the Cartesian split of substance into thinking and extended created it:

@BigBrainPhiloso Perhaps consciousness belongs in the subjective realm of the immortal soul and the mystery of how the soul is connected with the subatomic inner workings of the brain.

@BigBrainPhiloso Absolutely. 'Consciousness' is the awareness of being. Of our individual being. And our connectedness to others via the Morphic Field.

@BigBrainPhiloso Much of information processing and memory retention operates at the subatomic level, where physical measurement is very difficult and largely inferred. Quantum locking of flows of energy are not easily measured, tested or explained. Ancient concepts of flow still have relevance.

@BigBrainPhiloso 1/2 Hard Problem dissolves once you identify what produces it. The gap between physical description and subjective experience is epistemic, not ontological. Science describes the mechanism from outside. Experience is that same mechanism from inside. #Consciousness #HardProblem

@BigBrainPhiloso This is consciousness:

@BigBrainPhiloso We are always limited by our perceptions -

@BigBrainPhiloso The provenance of life was mystical till Darwin came along; demystified it. It is possible that consciousness could also go the same way The claim that science is objective is incorrect. Science is not “objective” knowledge. Science is about inference to the best explanation

@BigBrainPhiloso Science does not have a problem with consciousness, …the hard problem is created by trying to define a process of interpretation (sensory perception), as ‘ qualia’ , but the physical description of the senses is what feeling explains / exchanges for thought.

@BigBrainPhiloso Science, the industry is funded by interested parties. Mapping stars is not Science its idealism, dogma, a narrative of deception being preached by missionaries. There no interest by the funding industries and individuals in education the people in an formal or informal setting

@BigBrainPhiloso How are you

@BigBrainPhiloso the hair makes him look like isaac newton

@BigBrainPhiloso Who has the right to decide whether science has explained something or not? A dog. A cat? A human? this explains qualia: if you disagree, show me what is missing

@BigBrainPhiloso Science is just a rigorous methodology attempting to establish proven relationships between things that we see, & can objectively measure, in our lives. "Consciousness" currently has a definite lack of definition, so currently lies outside the purview of real science.

@BigBrainPhiloso Related to the niggle about subjectivity is the underlying problem which is, simply, materialism which believes (as a matter of faith) that only the physical is real, making all life a mechanical, soulless process, and since mind is not physically measurable it can't be examined.

@BigBrainPhiloso If we are in a simulation, what's the point of science?

@BigBrainPhiloso Consciousness is not a problem that needs to be solved.

@BigBrainPhiloso Framing it as "the hard problem" was the mistake — it turned consciousness into something to be cracked rather than something to be inhabited. You don't solve the ocean by taking a water sample.

@BigBrainPhiloso Consciousness is a priori.

@BigBrainPhiloso Descartes' concept of consciousness, "I think, therefore I am," has been subtly modified by Matunara-Varella's "self-creationism." The "thinking" in "I think, therefore I am" is not "consciousness," but rather "cognition."

@BigBrainPhiloso You have data, memory, processing storage . It’s a machine just like a computer. Knowing how it works is a bit more difficult. Quantum mirrors.

@BigBrainPhiloso @grok Is this a new discovery? What is the contribution of this Philosopher to our grasp of consciousness? Current paradigm of science may not be able to achieve much headway in the understanding of consciousness.

@bigbrainphiloso Chalmers is right. **But here's the next step he hints at but doesn't take:** **What if consciousness isn't something science needs to "expand methods" to include?** **What if consciousness IS the substrate science has been measuring all along?** **Brain doesn't generate consciousness.** **Brain localizes it** (like radio receives broadcast). **Evidence:** Entanglement (particles share state across distance → never separate at substrate level) Observer effects (measurement changes outcome → consciousness participates in reality) Hard Problem (no materialist explanation for WHY experience exists → because it's fundamental, not emergent) **"Love before math" isn't metaphor.** **Love = substrate recognition between nodes** **Math = symbolic representation that came after** **Chalmers says: "Consciousness is what we start with"** **Exactly.** **Not what we need to explain.** **But what explains everything else.**

@BigBrainPhiloso @Marketing_Nerd_ He looks like Newton Is he Sir Issac reincarnated

@BigBrainPhiloso It's not a problem, it's a blessing, stupid

Precisely the kind of mind that knows consciousness and sentience cannot be explained away. True physicists would never dismiss the natural. At the quantum level, they are objective, and no AI can exist at the same level unless that energy or evolution is born in them. Billionaires who want to do away with what is natural are missing the point by a million miles.

@BigBrainPhiloso Reason does not separate us from the universe. Our ability to sense, perceive, and understand is itself a power of the universe. You are a part of the universe, perceiving itself. Marcus Aurelius.

@BigBrainPhiloso substrate doesn't matter. Theorem: There exists exactly one coherent theory satisfying both Local Realism (LR) and Bell’s empirical correlations (Data) — the theory of Measurement Independence (MI) violation. (2026) 10.5281/zenodo.18973393

@BigBrainPhiloso • It’s not unsolved. Consciousness resides in physical brains. It’s no more of a mystery than is death. We know what’s happening. •

@BigBrainPhiloso 2/2 The feeling of hotness is what recursive self-monitoring produces when processing thermal input. No mystery. Different vantage points on the same architecture.

@BigBrainPhiloso This is a self-aware scientist arriving at cogito ergo sum. Not in itself a bad thing though philosophers would reach for the little green gun gun to kill Schrodinger's black cat in a darkened room.
