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.

Hickey’s Language and Consciousness
Language Organizes Consciousness but Does Not Create It
Raymond Hickey holds that thought and sensation are the two main aspects of conscious experience, and that language is used outwardly to communicate and inwardly to organize thought. Because thought and logical reasoning can survive the complete loss of language in severe aphasia, he concludes that language supplies content for consciousness but is not necessary for it. He traces how syntax, brain growth, and vocal anatomy evolved together, and argues that judging how conscious a being is ultimately requires it to describe its experience in language.
Raymond Hickey
What consciousness is
Hickey does not identify consciousness with anything; he describes it as composed of thought and sensation, with language organizing and communicating its contents.
Mind and body
Language has a physical side (articulation through the vocal apparatus) and a side Hickey calls non-physical, the brain’s generation of syntax and vocabulary. He links cognition to brain size relative to body mass.
Mechanism
Compositional, hierarchical syntax, which frees language from the here and now and makes abstract, symbolic thought expressible.
Core claims
- Severe aphasia shows that thought and logical thinking can survive the complete loss of language.
- Scholars divide over whether syntax arose gradually with pronunciation and vocabulary (continuity) or suddenly through a single mutation (discontinuity, associated with Chomsky).
- Cave art from about 50,000 years ago documents symbolic thought in early humans.
- Only beings with language can describe their conscious experience to others.
Criticisms
Calling the brain’s generation of syntax and vocabulary ‘non-physical’ sits uneasily with locating it in the brain. Requiring language to ascertain consciousness makes non-linguistic consciousness, which Hickey accepts, hard to verify.
Implications
- AI consciousness: Uncertain
- Hickey makes linguistic self-description the test for ascertaining consciousness but does not discuss machines that produce language.
