Panpsychism: The Philosophy That Consciousness Is Everywhere

What Is Panpsychism?

Panpsychism (from Greek pan, "all," and psyche, "mind" or "soul") is the philosophical view that consciousness is a fundamental and ubiquitous feature of the physical world. Just as every particle of matter has mass and charge, every particle of matter has some form of experience or proto-consciousness.

This is not the claim that electrons think about philosophy or that thermostats have feelings. It is the claim that experience, in some extremely minimal and rudimentary form, is a basic property of the physical world. Human consciousness is not something that appeared out of nowhere when brains became complex enough. It is the highly concentrated, highly integrated form of a quality that exists in all matter, at every scale.

The Hard Problem of Consciousness

David Chalmers, in 1995, distinguished between the "easy" problems of consciousness and the "hard" problem:

Easy problems (not actually easy, but in principle solvable with neuroscience): How does the brain process sensory information? How does it control behaviour? How does it integrate information from different senses? These are questions about mechanism: how the brain does what it does.

The hard problem: Why does physical processing in the brain give rise to subjective experience? Why is there "something it is like" to see red, taste chocolate, or feel pain? Even if we map every neuron and every synapse, we still do not know why the physical process produces an inner experience. You could build a perfect mechanical replica of a brain, and the hard problem would ask: does it feel anything? And how would you know?

Galileo's Error: How We Lost Consciousness

Philip Goff's book Galileo's Error (2019) argues that the hard problem of consciousness is a direct consequence of Galileo's scientific revolution. Before Galileo, the physical world was understood to have both objective properties (shape, size, motion) and subjective qualities (colour, sound, taste, smell). Galileo stripped the subjective qualities from the physical world: colours, sounds, and tastes are not in matter. They are in the mind. Matter itself has only mathematical properties.

This move made modern science possible. By reducing the physical world to what can be measured and mathematised, Galileo created the framework for physics, chemistry, and eventually neuroscience. But the move had a cost: consciousness was removed from the physical world. And once consciousness is removed from the physical world, getting it back in becomes the hard problem.

Goff's solution: reverse Galileo's error. Consciousness was never separate from matter. It was always there, as a fundamental property. Galileo's framework is correct for describing the mathematical structure of the physical world. But it is incomplete: it describes the extrinsic, relational properties of matter (how things interact) but says nothing about the intrinsic nature of matter (what things are, from the inside). Panpsychism fills the gap: the intrinsic nature of matter is experience.

Does Panpsychism Mean Rocks Think?

No. This is the most common misunderstanding, and addressing it clearly is essential.

Panpsychism proposes a spectrum of consciousness:

The key distinction: integration matters. A rock is an aggregate (a collection of atoms that are not highly integrated into a unified system). A brain is an integrated system (billions of neurons connected in a network that produces a unified experience). Panpsychism does not say that aggregates have rich consciousness. It says that the basic constituents of matter have some form of proto-experience, and that highly integrated systems (like brains) produce rich, unified consciousness from these basic constituents.

Integrated Information Theory: Consciousness as Phi

Giulio Tononi's Integrated Information Theory (IIT, first proposed in 2004) offers a scientific framework that is compatible with panpsychism. IIT's core claim: consciousness is identical to integrated information, symbolised as phi (Φ).

Integrated information = information generated by a system that is more than the sum of its parts. A system has high phi when its components are highly interconnected and the whole system generates information that cannot be reduced to the information generated by its parts independently.

• A human brain: Very high phi. Billions of neurons, massively interconnected, generating a unified experience that cannot be reduced to the experience of individual neurons.
• A photodiode: Very low phi. A single component that detects light. But nonzero phi: it integrates (minimally) the information of "light" and "no light."
• A rock: Possibly very low phi, because its atoms are not highly interconnected in an integrative way. A rock may have less integrated consciousness than its individual atoms, because it is an aggregate rather than a system.

IIT is empirically testable (it makes predictions about which brain states are conscious and which are not), and it is being tested in neuroscience laboratories. It is also compatible with panpsychism: if consciousness is integrated information, and some degree of integrated information exists in all physical systems, then some degree of consciousness exists everywhere.

The Combination Problem: Panpsychism's Hard Problem

If panpsychism solves the original hard problem (how does consciousness arise from non-conscious matter? Answer: it does not; matter was always conscious), it creates a new one: the combination problem.

The combination problem: if electrons have micro-experiences, how do billions of micro-experiences combine to form the unified, rich macro-experience of a human mind? How does the proto-consciousness of individual particles add up to the experience of seeing a sunset, understanding a theorem, or feeling love?

Ancient Roots: Thales to Spinoza to Whitehead

Panpsychism is not a modern invention. It is one of the oldest ideas in philosophy:

• Thales (c. 624-546 BCE): "All things are full of gods." The first philosopher attributed mind or spirit to all of nature, not just to living things.
• Anaxagoras (c. 500-428 BCE): Nous (mind) is the ordering principle of the cosmos. Mind is present in all things and is what gives them structure.
• The Stoics (3rd century BCE onward): The cosmos is permeated by logos (rational order, divine reason). The logos is in everything: in the stars, in the earth, in the human soul.
• Plotinus (c. 204-270 CE): The World Soul animates the entire cosmos. All matter participates in Soul, and through Soul, in Nous (Divine Mind), and through Nous, in the One.
• Spinoza (1632-1677): Mind and matter are two aspects of one substance (God or Nature). Everything in the universe has both a physical aspect and a mental aspect. This is "dual-aspect monism," a sophisticated form of panpsychism.
• Leibniz (1646-1716): The universe is composed of monads: simple, indivisible centres of perception. Every monad has experience. Physical objects are aggregations of monads.
• William James (1842-1910): In "Does 'Consciousness' Exist?" (1904), James argued for a radical empiricism in which experience is the fundamental stuff of reality.
• Alfred North Whitehead (1861-1947): Process philosophy. The basic units of reality are "occasions of experience": momentary events that have both a physical and an experiential dimension. This is panpsychism as process: reality is not made of things but of experiences.

The Modern Revival: Chalmers, Goff, Tononi, Koch

After decades of materialist dominance in philosophy of mind (the view that consciousness is identical to or produced by brain activity), panpsychism has experienced a significant revival in the 21st century:

• David Chalmers: The philosopher who named the hard problem takes panpsychism seriously as one possible solution. He does not fully endorse it but argues that it deserves careful consideration: "there is no direct evidence against panpsychism, and there are indirect reasons for taking the view seriously."
• Philip Goff: The most prominent contemporary defender. His Galileo's Error (2019) is the most accessible introduction to modern panpsychism. He argues that panpsychism is the simplest, most elegant solution to the hard problem.
• Giulio Tononi: The neuroscientist behind IIT. While IIT is not identical to panpsychism, Tononi accepts that IIT's implications are panpsychist: "consciousness is everywhere, it's in everything."
• Christof Koch: Former president of the Allen Institute for Brain Science. Koch has publicly embraced panpsychism through IIT, arguing that consciousness is a fundamental property of complex, integrated systems.

The Spiritual Meaning: A Conscious Universe

Panpsychism's spiritual implication is profound: you are not a conscious being in an unconscious universe. You are a conscious being in a conscious universe. The experience you are having right now (reading these words, feeling your body in the chair, hearing the ambient sound around you) is not an anomaly. It is the concentrated, highly integrated form of a quality that pervades all of reality.

The stars are not dead. The earth is not dead. The atoms in your body are not dead. Something is happening, from the inside, at every level of physical reality. Your consciousness is the most complex and integrated version of this something. But it is not the only version. It is one expression of a universal quality.
