Panpsychism, free will, and why consciousness reshapes our scientific worldview
Lex Fridman and philosopher Philip Goff explore panpsychism—the view that consciousness is a fundamental and ubiquitous feature of the physical world—and contrast it with materialism, dualism, and illusionism about consciousness.
Goff argues that standard physical science only captures the quantitative, behavioral structure of reality, not the qualitative, subjective aspect we know as experience, and that this gap motivates panpsychism as a rigorous middle way between materialism and dualism.
They discuss implications for morality (suffering, animal ethics, AI and robots), free will, expert authority in science, mystical experience, and the possibility of universal or shared consciousness.
The conversation closes with reflections on meaning, value, and whether there might be an objective purpose to existence, even if we can only live in hopeful uncertainty rather than certainty.
Key Takeaways
Panpsychism reframes the hard problem by starting from consciousness, not matter.
Instead of trying to derive subjective experience from purely quantitative physics, Goff proposes that consciousness is the intrinsic nature of physical reality and that physics describes only what matter does, not what it is.

Consciousness is not fully accessible to the standard scientific method.
Because experience is privately, not publicly, observable, the data of consciousness are different in kind from normal scientific data, requiring an expanded conception of science that incorporates first-person evidence and philosophical analysis.

Materialism and dualism each face serious explanatory costs.
Materialism struggles to account for qualitative experience in quantitative terms, while dualism is ontologically unwieldy and empirically underdetermined; panpsychism aims to keep a unified, physical world while respecting consciousness as basic.

Moral concern tracks consciousness and suffering, not just behavior.
Goff argues that consciousness is the basis of moral value: beings that feel can suffer and matter morally. ...

Free will is an open empirical question, not something science has disproven.
Goff finds no decisive scientific or philosophical argument against libertarian free will, suggests we don’t yet know enough about brain dynamics, and stresses the difference between random events and reason-responsive, uncaused choices.

Expertise is valuable but must be tempered by humility and openness.
Both speakers criticize how some scientific ‘experts’ communicated during COVID and more broadly; rigorous peer scrutiny is crucial, but so is listening seriously to outside challenges and communicating with clarity and modesty.

Panpsychism can coexist with, but doesn’t require, spiritual or mystical views.
While many panpsychists are secular, Goff notes that if consciousness is fundamental, reports of universal or mystical consciousness become at least philosophically intelligible and might even hint at an impersonal ‘life after death’ grounded in universal mind.

Questions Answered in This Episode
If physics only describes the causal structure of reality, what concrete steps could a ‘panpsychist science’ take to experimentally connect specific forms of experience to specific physical structures?

How should we design and regulate future AI and robots if we can never be certain whether they are conscious or merely perfect behavioral ‘zombies’?
Goff argues that standard physical science only captures the quantitative, behavioral structure of reality, not the qualitative, subjective aspect we know as experience, and that this gap motivates panpsychism as a rigorous middle way between materialism and dualism.

Does accepting panpsychism meaningfully change how we should treat animals, plants, and ecosystems in law and public policy, or is it mainly a metaphysical reframe?

I believe our official scientific worldview is incompatible with the reality of consciousness.
Do you think we're living in a simulation?
We could be in the Matrix. This could be a very vivid dream.
There's going to be a few people that are now visualizing a pink elephant.
A hamster has consciousness.
Except for cats, who are evil automatons that are void of consciousness.
Consciousness is the basis of moral value, moral concern.
Do you think there will be a time in, like, 20, 30, 50 years when we're not morally okay turning off the power to a robot? (deep breath) The following is a conversation with Philip Goff, philosopher, specializing in the philosophy of mind and consciousness. He is a panpsychist which means he believes that consciousness is a fundamental and ubiquitous feature of physical reality of all matter in the universe. He is the author of Galileo's Error: Foundations for a New Science of Consciousness and is the host of an excellent podcast called Mind Chat. This is the Lex Fridman Podcast. To support it, please check out our sponsors in the description and now, here's my conversation with Philip Goff. I opened my second podcast conversation with Elon Musk with a, uh, question about consciousness and panpsychism. The question was, quote, "Does consciousness permeate all matter?" I don't know why I opened the conversation this way. He looked at me like, "What the hell is this guy talking about?" So, he said no, because we wouldn't be able to tell if it did or not so it's outside the realm of the scientific method. Do you agree or disagree with Elon Musk's answer?
I disagree. I guess I, I guess I do think consciousness pervades matter. In fact, I think consciousness is, is the ultimate nature of matter. Um, so as for whether it's outside of the scientific method, I think there's a fundamental challenge at the heart of the science of consciousness that we need to face up to which is that consciousness is, is not publicly observable, right? I can't look inside your head and see your feelings and experiences. We know about consciousness not, you know, not from doing experiments or public observation. We just know about it from our, our immediate awareness of our, our feelings and experiences. So-
Qualitative, not quantitative, as you talk about.
Yeah, that's another aspect of it there. So, there are a couple of reasons consciousness, I think, is not susceptible to the standard, or not fully susceptible to the standard scientific approach. One reason you've just raised is that it's qualitative rather than quantitative. Another reason is it's not publicly observable. So, I mean science, science is used to dealing with, uh, unobservables, right? You know, fundamental particles, quantum wave functions, other universes. None of these things are observable, but there's an important difference. With all these things, we postulate unobservables in order to explain what we can observe, right? In, in the whole of science, that's, that's the, that's how it works. In the case of consciousness, in the unique case of consciousness, the thing we are trying to explain is not publicly observable and that is utterly unique. If we wanna fully bring science into consciousness, we need a more expansive conception of the scientific method. So, it doesn't mean we can't explain consciousness scientifically, but we need to rethink what science is.
