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
Hacker’s Skepticism
Consciousness as Capacities of Persons, Not a Thing
Hacker, following Wittgenstein, argues that consciousness is no thing, substance, or brain state but a family of capacities and states of whole persons, such as perceiving, thinking, feeling, intending, and being self-aware. The hard problem, on his view, is a conceptual confusion produced by misusing language, so it calls for philosophical clarification, not neuroscientific explanation.
Peter Hacker
What consciousness is
Consciousness is not an entity to be identified with anything. The word picks out a range of logically interconnected capacities and states of living beings, rooted in behaviour and language use; to be conscious is to be a certain kind of being, a human or sentient animal.
Mind and body
Psychological predicates apply to whole persons, not to brains or sub-personal mechanisms. Saying the brain thinks or is conscious commits a category mistake; neuroscience shows how the brain enables perception and behaviour, not what consciousness is.
Mechanism
Grammatical analysis: philosophical problems about consciousness are dissolved by tracing how psychological words are used and showing where reification leads to nonsense.
Core claims
- Treating consciousness as an object or entity in the brain is a category mistake.
- Psychological predicates apply to persons, not to their brains or parts.
- The hard problem arises from conceptual confusions that make it seem as if there is something to solve.
- Neuroscience cannot answer philosophical questions about consciousness, because those questions are conceptual, not empirical.
Criticisms
Defenders of the hard problem reply that analysing how ‘I feel pain’ is used does not show why pain feels as it does, so dissolving the problem may simply sidestep it. Hacker's denial that neuroscience can explain consciousness also sits uneasily with much current consciousness research.
Implications
- Survival beyond death: Unlikely
- Since consciousness consists in the capacities of a living human being or animal, it follows that nothing conscious remains once that being has died.
- Meaning and purpose: Humanistic only
- Hacker places consciousness within human life, behaviour, and language and sees philosophy's task as clarifying our understanding, with no cosmic dimension.
