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.
Non-Reductive
Sperry’s Mentalist Paradigm
Consciousness as a Causal Emergent of Brain Function
Sperry holds that consciousness is a nonreductive, dynamic emergent of brain activity that exerts real top-down control over the neural processes it arises from. He calls the view ‘Mentalist Monism’: one world, no unembodied mind, but with mental properties as genuine causes of behavior.
Roger Sperry
What consciousness is
Conscious experience is an emergent property of upper levels of certain brain processes, with causal power over the lower-level events that make it up.
Mind and body
Mind and brain are inseparable but different, in the way an emergent property differs from its infrastructure. Sperry rejects both classic dualism and mind-brain identity theory.
Mechanism
Emergent determinism: top-down control of the parts by the emergent whole. Sperry puts it as the question of ‘who pushes whom around’ among the causal forces in the cranium.
Core claims
- The overthrow of behaviorism by mentalism in behavioral science supports treating behavior as mentally driven.
- Conscious experience cannot exist apart from the brain, yet it is not identical to brain processes.
- Higher-level brain systems control the timing and flow of impulse traffic through individual neurons.
- Downward causation contradicts the micro-deterministic premises of traditional materialism, which exclude consciousness from explanation.
Criticisms
The view clashes with micro-deterministic science, which allows only bottom-up causation. Sperry complains that it has been misread as dualism, identity theory, strict functionalism, and dualist or emergent interactionism, which suggests its position is hard to pin down.
Implications
- AI consciousness: Uncertain
- Sperry ties consciousness to the brain but describes it in generalized functional terms, so whether an artificial system could host it is left open.
- Survival beyond death: No
- Sperry states there is no provision for unembodied consciousness, mind, or spirit; consciousness cannot exist apart from the brain.
- Meaning and purpose: Humanistic only
- Sperry wants to close the gap between value-free science and purposeful, value-laden humanistic views by giving consciousness a legitimate causal role.
- Virtual immortality: Uncertain
- Since consciousness is an emergent of brain activity, reproduction elsewhere would depend on recreating that emergent whole, which Sperry does not address.
