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.
Challenge
Wittgenstein's Grammatical Fiction
The Private Inner Object as Grammatical Fiction
Wittgenstein argues that the demand for a theory of phenomenal consciousness comes from a grammatical confusion: treating sensation-words as names of private inner objects, the way nouns name public things. He does not deny pain, seeing red, or first-person immediacy; he relocates their meaning in public, embodied, rule-governed practices of expression and use.
Ludwig Wittgenstein
What consciousness is
Wittgenstein gives no identity for consciousness. He treats the picture of an inner object named by the word ‘pain’ as the fiction, while the experience itself remains; a sensation ‘is not a something, but not a nothing either’ (PI §304).
Mind and body
Inner and outer are not two independent domains linked by uncertain inference. Human expressive life is the setting in which psychological concepts make sense, and in the aspect-perception remarks Wittgenstein holds that physiological explanation leaves the psychological concept untouched.
Mechanism
The private language argument (PI §§243–315). A diarist who marks a sensation ‘S’ by inner pointing has no criterion separating correct from incorrect use, so ‘whatever is going to seem right to me is right’, and talk of ‘right’ lapses.
Core claims
- A language whose words refer to what only the speaker can know cannot be established, because it has no criterion of correct use.
- In the beetle-in-the-box, the box's contents can differ, change, or be absent without disturbing the word's use, so they ‘cancel out’ of its meaning.
- The sensation is a grammatical fiction only as the picture of an inner object; Wittgenstein explicitly rejects the behaviorist reading.
- In aspect perception, the dawning of an aspect is an internal relation between objects, neither a change in the world nor an inner object, and physiology leaves it unexplained.
Criticisms
Phenomenal realists object that the beetle argument settles reference, not existence. At PI §272 Wittgenstein himself allows that different groups might have different red sensations, which seems to need the private difference the beetle passage dissolves. Kripke's rule-following reconstruction is rejected by many Wittgensteinians as unfaithful.
Implications
- AI consciousness: Uncertain
- Psychological concepts apply by public criteria within a form of life, and Wittgenstein's corpus here does not settle whether a machine could meet them.
