Consciousness Explained?
What David Chalmers Teaches Us About the Mystery of Mind
The raw feeling of being alive, of seeing, tasting, sensing has long puzzled philosophers and scientists alike. We know what it’s like to hear music or see the color red, but we can’t say why it feels that way. Where in the brain does experience actually happen?
David J. Chalmers, one of the most influential thinkers in modern philosophy of mind, takes this question seriously. In his groundbreaking book The Conscious Mind (1996) and his essay ‘Facing Up to the Problem of Consciousness’ (1995), Chalmers lays out a roadmap for understanding consciousness—not as a trick of biology or an illusion, but as something fundamental to the fabric of reality.
Chalmers begins by dividing the study of consciousness into two categories:
✅ The Easy Problems
These are questions about brain function:
How does the brain react to sights and sounds?
How do we focus attention?
How do we describe or report what we experience?
These problems may be difficult in practice, but they can be solved using standard methods in neuroscience and cognitive science.
❓ The Hard Problem
This is the real puzzle:
Why does any of this brain activity lead to subjective experience?
Why do certain patterns of brain activity feel like something from the inside? Why doesn’t the brain operate in total silence, like a machine without any inner world?
This, Chalmers argues, is not just another technical challenge. It’s a different kind of problem altogether—one that cannot be solved by simply mapping the brain more closely.
Many popular theories attempt to explain consciousness by pointing to brain functions:
Crick and Koch link it to synchronized neural firing.
Baars’s Global Workspace Theory says it’s about making information globally available in the brain.
Dennett suggests it’s an illusion built from multiple drafts of perception.
Chalmers shows how all of these may explain how the brain behaves, but not why these behaviors come with an inner life. In short: they solve the easy problems, not the hard one.
Chalmers believes we need a radical shift in thinking.
Just as physics had to introduce electric charge as a basic property to explain electricity, we may need to treat consciousness itself as a fundamental feature of the universe.
That means it can’t be broken down or explained in terms of something else. It simply is—like mass, energy, or space-time.
This idea is bold. But it allows us to take consciousness seriously without falling into mysticism or vague metaphor.
To explain consciousness, Chalmers proposes what he calls naturalistic dualism:
Conscious experience is real and fundamental.
It doesn’t replace physical science—it complements it.
We need new psychophysical laws that connect physical systems to conscious experiences.
This is not a return to old-school mind-body dualism. It’s an updated, scientifically responsible way of admitting that experience isn’t just a byproduct of biology—it’s something we must build into our models of the world.
🧠 Three Key Ideas for a New Science of Consciousness
Chalmers lays out three guiding principles that could help bridge the gap between brain activity and conscious experience:
1. Structural Coherence
The structure of our experiences (like how we perceive colour or sound) mirrors the structure of how information is processed in the brain.
For example, the way we experience color follows a three-dimensional space—similar to how our photoreceptor cells respond to light.
2. Organizational Invariance
If two systems—human or artificial—have the same functional organization, they will have the same experiences.
A thought experiment: Replace each neuron in your brain with a silicon chip that does the same job. According to Chalmers, your experience would stay the same—suggesting that it’s the organization that matters, not the material.
3. Information Has Two Aspects
Information is not just physical. It may also have a phenomenal aspect—a “feel.”
Consciousness could be the inner face of information, just as physics is its outer structure.
These three ideas form the skeleton of a possible science of consciousness—one that treats experience as real and measurable, even if radically unfamiliar.
🧠 Artificial Intelligence
If consciousness depends on structure, not biology, then a well-designed AI might one day be conscious. That changes how we think about machines, rights, and moral responsibilities.
⚖️ Ethics
If we take consciousness seriously, we must rethink how we treat any system—human or artificial—that might have experience.
🔬 Science
Naturalistic dualism urges us to expand the boundaries of science. Consciousness, like space-time or gravity, may need to be added to our list of what the universe is fundamentally made of.
🧭 Conclusion: A New Path Forward
David Chalmers doesn’t offer an easy answer. But he gives us a clear path—and a challenge:
Stop pretending consciousness is an illusion.
Start building a science that treats it as real.
The mystery of consciousness may not lie in more brain scans or algorithms, but in learning to speak a new scientific language—one that includes us, the experiencers, at its center.

Consciousness is fundamentally important because it enables subjective experience, self-awareness, and the capacity for complex thought and action. It allows individuals to perceive the world, process information, make decisions, and learn from experiences. Without consciousness, there would be no subjective “self” to experience life or engage with the world in a meaningful way.
