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.

Cabral-Calderin, Hechavarria, and Melloni’s Neuroethological Approach
Consciousness Studied Across Species and Lifespans
Cabral-Calderin, Hechavarria, and Melloni propose studying consciousness across species and across the lifespan using Tinbergen's four questions: mechanism, function, development, and evolution. They treat consciousness as a graded, multidimensional product of evolution and argue that nonhuman animals should not have to show adult human traits such as verbal report to count as conscious.

What consciousness is
Consciousness is a graded biological property shaped by evolutionary pressures and expressed differently across taxa and developmental stages. It includes both phenomenal consciousness (felt experience) and access consciousness (information available for cognition and behaviour).
Mind and body
Consciousness depends on neural mechanisms that must be understood in the ecological, developmental, and evolutionary context of the organism that has them.
Mechanism
Tinbergen's four levels of analysis applied to consciousness: causation (neural mechanism), function (adaptive purpose), ontogeny (development), and phylogeny (evolution).
Core claims
- Brain mechanisms alone, or adult humans taken as the gold standard, cannot explain consciousness; all four Tinbergen levels are needed.
- The burden of proof should not fall on animals to display adult human traits such as verbal report.
- Evidence from human fetuses and newborns suggests that the foundations of consciousness arise before birth.
- Large language models may mimic verbal output but lack the biological embodiment and evolutionary history the authors consider necessary for genuine experience.
Criticisms
Using neural markers from human-based theories to detect consciousness in other species risks bringing back the human-centric standard the approach aims to drop. The authors themselves caution that neural markers must be read in ecological context.
Implications
- AI consciousness: Unlikely
- The authors argue that systems such as large language models lack the biological embodiment and evolutionary history needed for genuine conscious experience.
- Survival beyond death: No
- Since consciousness here is a property of living, evolved nervous systems, it follows that it ends with the organism.
- Meaning and purpose: Humanistic only
- Consciousness serves adaptive functions within an organism's ecology, with no cosmic purpose proposed.
- Virtual immortality: Unlikely
- If biological embodiment is needed for experience, a digital copy would lack what makes consciousness possible.
