The Consciousness Atlas is an interactive web app that visualizes more
than 450 theories of consciousness. It is based on Robert Lawrence
Kuhn's 2024 paper,
"A Landscape of Consciousness". The Atlas maps theories that address phenomenal consciousness - the
subjective feel of experience, such as the redness of red.
What the Atlas is
The Atlas is a visual reference built on Kuhn's taxonomy. It presents
the full set of theories at once so you can explore the field visually
and open any theory to read its entry, like an encyclopedia with
structured entries. Each theory entry shows a concise identity line,
conceptual ground, suggested mechanism, empirical notes, implications,
and sources.
Why this exists
Consciousness is studied across disciplines - neuroscience,
philosophy, and sometimes spiritual or anomalous-state research.
Kuhn's paper collects and organizes hundreds of theories along a
spectrum from most physical to least physical. The Atlas puts that
organization into a visual form so readers, students, and researchers
can quickly see how different positions relate and where each theory
sits on the spectrum.
How it works
Theories are grouped into ten main categories, arranged by their
stance on the physical-to-nonphysical spectrum. Examples of categories
include Materialism, Non-Reductive Physicalism, Functionalism,
Quantum-based theories, Panpsychism, Monism, Dualism, Idealism,
Anomalous States, and Challenge Theories. The app shows the whole map
at once. Click any theory to read its structured entry, which includes
references to canonical sources and named thinkers.
Who it is for
- Students learning philosophy of mind and cognitive science
-
Researchers and lecturers looking for an at-a-glance comparative
resource
-
Journalists and writers who need a quick reference to the range of
positions
-
Curious readers who want a clear view of what people mean when they
talk about consciousness
What the Atlas does not do
The Atlas does not endorse or rank theories. It is a visualization and
reference based on Kuhn's taxonomy - collect and present, not judge.
It does not attempt to settle the hard problem of consciousness. It is
a tool for exploration and comparison.
A note from Kuhn
Kuhn explicitly states the project's purpose: "collect and categorize,
not assess and adjudicate." The Consciousness Atlas follows that
approach. The data and structure are derived from Kuhn's paper;
feedback and suggested corrections are welcome, but the app is a
visualization layer on top of Kuhn's work.
Kuhn was not involved in the design or content of the Consciousness
Atlas, other than his original paper, 'A Landscape of Consciousness,'
which is the sole source.
FAQ
What is phenomenal consciousness?
Phenomenal consciousness refers to subjective experience - the
qualitative feel of being aware, like the taste of coffee or the
redness of red.
How many theories does the Atlas include?
The Atlas visualizes over 220 individual theories, grouped into ten
broad categories.
Does the Atlas show which theory is true?
No. The Atlas presents theories neutrally. It is a map, not an
argument for any single position.
Is the Atlas academic?
The Atlas is based on an academic source - Robert Kuhn's 2024 paper,
"A Landscape of Consciousness" - and links to canonical sources
where available.
Summary
The Consciousness Atlas is a straightforward visualization tool: it
presents Kuhn's taxonomy as a single, explorable map and lets users
open individual theory entries to read structured, referenced
summaries. It is designed to make this complex field easier to survey
and to serve as a practical reference.

Cai and Cai’s Canxian
Consciousness as a Non-Local Web of Cognitive Units
Hengjin Cai and Tianqi Cai argue that consciousness emerges from physical processes as a real, non-local level of reality with its own causal power. Minds ‘canxianize’ the continuous flow of spacetime events into discrete, shareable cognitive units called Cognitive Canxians, and the first of these is the Self, rooted in a cell membrane's boundary between me and not-me.

What consciousness is
Consciousness is a non-local organizational structure built from countless Cognitive Canxians: units a cognitive subject creates by editing and grouping the four-dimensional continuum of physical events.
Mind and body
Only physical processes exist fundamentally, but the conscious level is real and irreducible. The key mind–body contrast is the strict locality of physics versus the intrinsic non-locality of the conscious level, not two substances.
Mechanism
Canxianizing: a creative, non-linear editing of spacetime that conflates similar but distinct physical processes into one repeatable cognitive unit, freeing the organism from moment-to-moment physical causality.
Core claims
- Raw physical reality is a continuous manifold of events with no built-in objects; minds carve it into Cognitive Canxians.
- Hume's ‘necessary connexion’ is created at the psychological level to guide action, which the authors offer as an answer to the problem of induction.
- Higher-level Canxians exert downward causation on physical components, so consciousness is no epiphenomenon.
- Qualia compress physiological states into actionable meaning to coordinate an organism's specialized modules.
Criticisms
Claiming genuine downward causation from a non-local conscious level while holding that only physical processes exist fundamentally is a tension shared by many strong-emergence views. Calling consciousness ‘non-local’ is a metaphor for shared, transferable meaning, which may blur the line between individual experience and public culture.
Implications
- AI consciousness: Possible
- Since consciousness is an organizational structure born from physical processes, a system that forms transferable Canxians could qualify, and both authors work on conscious AI and human-machine symbiosis. Qualia, however, depend on an embodied causal history.
- Survival beyond death: Unlikely
- The Self is anchored in a living organism's physical boundary, so personal experience ends with it, though shared cultural Canxians can outlast any individual.
- Meaning and purpose: Humanistic only
- Meaning is built by minds and spread through communities as shared Canxians, with no cosmic purpose assumed.
- Virtual immortality: Unlikely
- Qualia are described as a non-replicable resonance across one body's entire history, which makes a faithful copy doubtful.
