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.
Monism
James’s Radical Empiricism of Monistic Pure Experience
Consciousness as a Function Within Pure Experience
William James argues that mind and matter are two ways of organizing one more basic field of ‘pure experience’, which is itself neither mental nor physical. The same bit of experience counts as a physical object in one set of relations and as someone’s perception in another, so consciousness names a function, not a substance.
William James
What consciousness is
Consciousness is pure experience taken in certain relations: retrospective, appropriative, personal, cognitive, practical and affective. The physical is the same experience taken in relations of stability, resistance, publicity and causal efficacy.
Mind and body
Mind and body are two orderings of one stock of experience. James's example is a room, which belongs to a physical series with its own history and laws and also to a perceiver's biography, without being duplicated.
Mechanism
Double counting: one portion of experience enters two relational contexts and so plays two roles. What makes an item mental is the company it keeps, not an intrinsic mark.
Core claims
- James holds that ‘consciousness’ names no entity or stuff, only a function performed within pure experience.
- One bit of experience can belong to both a physical series and a mental series, so mind and matter differ only in their relations.
- Radical empiricism treats relations as directly experienced, which removes the need for a transcendental ego to unify experience.
- There is no single neutral stuff; each bit of experience is made of whatever qualities appear in it.
Criticisms
Critics ask whether pure experience is genuinely neutral: if the basic stuff is ‘experience’, the view may be idealism in disguise. Others doubt that the two-orderings device explains phenomenal character, as opposed to relocating it. Contemporaries misread the 1904–05 essays and some psychologists took James to have abandoned psychology.
Implications
- Survival beyond death: Uncertain
- In Human Immortality James proposed that the brain might transmit rather than produce consciousness, but he declined to claim the evidence settled the question of survival.
- Meaning and purpose: Uncertain
- The theory sets out a pluralistic, open universe with no single closed system, and does not by itself supply a cosmic purpose.
