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.
Phenomenology
James’s Stream of Thought/Consciousness
Consciousness as a Continuous, Selective Stream
William James describes consciousness as a continuous, personal, ever-changing stream rather than a chain of discrete ideas. Each moment includes a focal object plus a felt fringe of relations, tendencies, and meaning, all held within a temporally thick ‘specious present’ and shaped by interest and attention.
William James
What consciousness is
Consciousness is a flowing field of experience: a focal content surrounded by a fringe of felt relations, bodily tone, affect, and temporal direction, owned by a person and always changing.
Mind and body
In the Principles, James takes thoughts, feelings, and a physical world as given data without deciding their ultimate relation. He still argues against epiphenomenalism, holding that consciousness must be causally effective because evolution selected it.
Mechanism
James names five characters of thought: it is personal, always changing, sensibly continuous, directed at objects, and selective. The fringe and the specious present give each moment its relational and temporal depth.
Core claims
- Thought is sensibly continuous, so any break in the stream is inferred rather than experienced.
- Transitive feelings of relation are as real in experience as substantive sensory contents.
- The experienced present is a ‘saddle-back’ with its own breadth, not a knife-edge instant.
- Consciousness selects its objects by interest, which makes it causally effective rather than epiphenomenal.
Criticisms
Edmund Husserl acknowledged that his concept of the horizon derives from James’s fringe, but held that James described experience without the phenomenological reduction and so left the analysis tied to psychological and physiological assumptions. Geniusas argues that Husserl removed an arbitrariness in the fringe by depsychologizing it.
Implications
- Survival beyond death: Possible
- The stream theory itself is silent, but James elsewhere proposed that the brain might transmit rather than produce consciousness. He declined to say the evidence settled the question of survival.
- Meaning and purpose: Humanistic only
- Meaning appears in the stream as interest, selection, and felt significance in a person’s life; the theory proposes no cosmic purpose.
