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.

Merriam’s Calculus of Qualia as Logical Primitives
Qualia as Non-Referential Logical Primitives
Paul Merriam's Calculus of Qualia is a formal system with non-referential terms, such as █, that present an experience directly in awareness instead of referring to it. On this view qualia are logical primitives, irreducible and not further explainable, and Merriam argues that adequate theories of mind need such presentational terms alongside ordinary referential ones.
Paul Merriam, Mohammed A. Z. Habeeb
What consciousness is
Qualia are logical primitives whose meaning is their own presentation. A non-referential term like █ instantiates the quale when it appears; it does not denote it.
Mind and body
The hard problem becomes ‘why is physical process p correlated to █?’, and Merriam suggests answers would involve experiential pathways, such as turning a referential brain thought into █.
Mechanism
Non-referential, presentational terms. A Naming Calculus with name and referent operators collapses for such terms, and the Reference Barrier Theorem shows no well-formed qualation can equate a referential term with a non-referential one.
Core claims
- Languages from Frege to Husserl and Heidegger are bound by reference and so cannot capture the immediacy of qualia.
- A dual theory of truth separates referential truth (correspondence) from presentational truth (accurate instantiation), and the Truth Barrier Theorem says no term has both.
- The zombie argument dissolves: saying a zombie lacks █ requires presenting █, so its absence cannot be coherently stated.
- Phenomenal-concept and quotational strategies remain referential, so by the Reference Barrier they cannot capture presentation.
Criticisms
Merriam presents the zombie result as a logical dissolution, not an empirical refutation. The calculus states that qualia are irreducible but does not explain why physical processes correlate with them.
