Quantum Physics: Is Everything Determined? Egnor vs. Papineau

Physicalist philosopher David Papineau is clearly unhappy with the implications of quantum mechanics, as neurosurgeon Michael Egnor sets them out

Yesterday, we published the fifth portion of the debate between materialist philosopher David Papineau and neurosurgeon Michael Egnor, where the key issue was “Can traditional philosophy help us understand the mind vs. the brain?” In this final instalment, we look at the portion which starts roughly at 47 min where Papineau and Egnor start to talk about quantum physics, the physics that governs electrons, which famously do not obey the same rules as larger particles and are also the most basic level of the brain (partial transcript): Note: Dr. Papineau is a “physicalist.” On that view, “the mind is a purely physical construct, and will eventually be explained entirely by physical theory, as it continues to evolve.” (Philosophy basics) He…

Can Traditional Philosophy Help Us Understand Mind vs. Brain?

Michael Egnor asks us to look back to the traditional idea that the soul is the “form” of the body

Yesterday, we published the fourth portion of the debate between materialist philosopher David Papineau and neurosurgeon Michael Egnor, where the key issue was “Is the mind simply what the brain does?” Today, we look at the portion which starts roughly at 36 min where Papineau and Egnor start to talk about traditional philosophical ways of thinking about the soul and the body (partial transcript): Note: Dr. Papineau is a “physicalist.” On that view, “the mind is a purely physical construct, and will eventually be explained entirely by physical theory, as it continues to evolve.” (Philosophy basics) He is considered to be one of the best defenders of naturalism (nature is all there is), often called “materialism.” Michael Egnor: In the…

Can a Materialist Consciousness Theory Survive Quantum Mechanics?

Quantum mechanics requires that the observer be part of the measurement; thus quantum measurements must include consciousness

In Walter Bradley Center director Robert J. Marks’s second podcast with philosopher Angus Menuge, where the big topic is the perennial “Hard Problem of consciousness, one of the questions was whether quantum mechanics can help decipher consciousness. But that leads to another question: Can any materialist view of consciousness survive quantum mechanics? https://episodes.castos.com/mindmatters/Mind-Matters-134-Angus-Menuge.mp3 This portion begins at 22:35 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks: Is quantum consciousness rooted in materialism? Can you look at quantum consciousness and say, this is materialistic? Angus Menuge: That’s a tricky question. For most materialists, their paradigm is really set by older 19th-century views of physical science. By definition, this goes beyond that. However, if one defines materialism…

Can Quantum Mechanics Help Decipher Consciousness? Free Will?

Nobel laureate Roger Penrose, among others, looked to the quantum world for models

In Walter Bradley Center director Robert J. Marks’s second podcast with philosopher Angus Menuge, the big topic is the perennial “Hard Problem of consciousness and various proposed solutions. One of the questions that oftem\n comes up is quantum consciousness. Earlier, they had discussed Integrated Information Theory (IIT) and panpsychism. But now, what about recent Nobelist Roger Penrose’s approach: quantum consciousness? https://episodes.castos.com/mindmatters/Mind-Matters-134-Angus-Menuge.mp3 This portion begins at 18:22 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks (pictured): Okay. Another model of consciousness of which I am aware is so-called quantum consciousness. I’m really interested in this because reading the works of Roger Penrose, he maintains that humans can do non-algorithmic things. And he looked around at the…

Why Do Some Famous Materialist Scientists Hate Philosophy?

Philosopher of biology Massimo Pigliucci takes Richard Dawkins to task for dismissing philosophy but he might have said the same of Stephen Hawking

Massimo Pigliucci (pictured) makes clear that he is a naturalist (materialist) like zoologist Richard Dawkins. For example, he tells us that they crossed paths at a conference whose purpose was to promote naturalism (materialism): Over four centuries of scientific progress have convinced most professional philosophers and scientists of the validity of naturalism: the view that there is only one realm of existence, the natural world, whose behavior can be studied through reason and empirical investigation. The basic operating principles of the natural world appear to be impersonal and inviolable; microscopic constituents of inanimate matter obeying the laws of physics fit together in complex structures to form intelligent, emotive, conscious human beings.

Trying To Disprove Free Will Shows That Materialism Doesn’t Work

If you have a metaphysical theory and it contradicts science, logic, and everyday experience, then your metaphysics should be abandoned

Biologist Jerry Coyne, who is also an atheist activist, offers another post denying free will. Journalist Oliver Burkeman published an essay at the The Guardian last week, asking, “The clockwork universe: is free will an illusion?”, quoting Coyne among others. Coyne, who believes that free will is indeed an illusion, offers support at his blog. Read at your leisure but note: He ignores critical science issues around free will, including the following: 1. Nature is not deterministic. The fact that nature is not predetermined in detail has been shown quite convincingly by the experimental confirmation of Bell’s theorem in quantum mechanics. Succinctly, over the past 50 years, at least 17 teams of researchers have asked and answered the question: does…

Could the World Above the Level of the Particle Be Superposed?

It’s been done with molecules. After that, there are barriers

In last week’s podcast,,” our guest host, neurosurgeon Michael Egnor, interviewed idealist philosopher of science and physicistBruce Gordon on how the quantum physics that underlies our universe makes much more sense if we have a non-materialist view of reality. Even then, it challenges our conventional view of how nature “must” work: We were introduced to the quantum eraser experiment, which showed that what happens at the level of individual particles depends on whether you choose to measure it or not and to non-locality, the Cheshire Cat’s science of being in no one particular place at any time. Particles can do that even if we can’t. But wait: Is it possible that things larger than particles can in fact do that…

In Quantum Physics, “Reality” Really Is What We Choose To Observe

Physicist Bruce Gordon argues that idealist philosophy is the best way to make sense of the puzzling world of quantum physics

In last week’s podcast,,” our guest host, neurosurgeon Michael Egnor, interviewed idealist philosopher of science and physicist Bruce Gordon on how the quantum physics that underlies our universe makes much more sense if we have a non-materialist view of reality. Even then, it challenges our conventional view of how nature “must” work: https://episodes.castos.com/mindmatters/Mind-Matters-130-Bruce-Gordon.mp3 A partial transcript, Show Notes, and Additional Resources follow. Michael Egnor: When I was in college, I was a biochemistry major and I took some courses in quantum mechanics. It was noted in the course that when you look at the most fundamental properties of subatomic particles, matter seems to disappear. That the reality of the subatomic particles is that they’re mathematical concepts. It utterly fascinated me…

The World’s First Quantum Chess Tournament Announces a Winner

Quantum chess allows for superposition, entanglement, and interference

Perimeter Institute’s Aleksander Kubica won: So what’s quantum chess? It’s a complicated version of regular chess that incorporates the quantum concepts of superposition, entanglement, and interference. “It’s like you’re playing in a multiverse but the different boards [in different universes] are connected to each other,” said Caltech physicist Spiros Michalakis during a livestream of the tournament. “It makes 3D chess from Star Trek look silly.” Jennifer Ouellette, “We have a winner in the world’s first quantum chess tournament” at Ars Technica Okay: Superposition: Elementary particles of our universe are not in one single specific place, they are only in a probable one. Entanglement: What happens to one elementary particle affects any other particle entangled with it, no matter how far…

Could Slowing Quantum Processes Lead To More Useful Computing?

“Adiabatic” quantum computing slows down the process, in the hope of achieving more reliable quantum positions

In a recent podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange but important to our future. They discussed the prospects of slowing down quantum computing to make it more useful (adiabatic computing). https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The discussion of quantum communication begins at approximately 58:47. The Show Notes and transcript follow. Enrique Blair (pictured): I guess the challenge with entangling massive numbers of quantum systems is that entanglement becomes much more fragile. In quantum communication, you just need pairs of photons to be entangled. One with another, that’s it. Whereas with quantum computing, you need many, many systems to be entangled, and that’s just…

The Final Ambiguous Truth About Schrödinger’s Cat

Schrödinger came up with the cat illustration to explain quantum mechanics to interested people who were not physicists

In last week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange. Inevitably, the discussion turned to what really happened with Schrödinger’s cat, the one who is either dead or alive only if we actually look at it. https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 [Schrödinger’s cat starts approximately at 21:50.] The Show Notes and transcript follow. Excerpts from the transcript: Robert J. Marks (pictured): We hear a lot in popular culture about Schrödinger’s cat. Now, Erwin Schrödinger (1887–1961) was one of the guys who formulated quantum mechanics. He won a Nobel Prize for it. He was trying to explain quantum mechanics to a layperson and he used…

How Scientists Have Learned To Work With the Quantum World

It’s still pretty weird, though

In last week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange. But scientists have learned to work with QM, despite many questions, like how to work with particles that can be in two different places (quantum superposition): https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 [Starts at approximately 13:16.] The Show Notes and transcript follow. Excerpts from the transcript: Robert J. Marks: What’s superposition? What’s going on there? Enrique Blair: Quantum superposition is really a mathematical description. We use wave functions to describe these particles. There’s a wave function for the photon going through Slit One and a wave function for the photon going through Slit Two. To…

Here’s Why the Quantum World Is Just So Strange

It underlies our universe but it follows its own “rules,” which don’t make sense to the rest of us

In this week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why Quantum mechanics pioneer Niels Bohr said, “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.” Let’s look at some of the reasons he said that: https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The Show Notes and transcript follow. Enrique Blair: It’s really quite different from our daily experience. Quantum mechanics really is a description of the world at the microscopic scale. And it’s really weird, because there are things that initially we thought maybe were particles but then we learned that they have wave-like behaviors. And there are other things that we thought were waves and then we…

A Materialist Gives Up on Determinism

Evolutionary biologist Jerry Coyne undercuts his own argument against free will by admitting that quantum phenomena are real

Evolutionary biologist Jerry Coyne has denied free will for years. But most recently, he has said something that puts the whole matter in doubt. A bit of background: Free will simply cannot be real if determinism is true, that is, if everything in nature falls like dominoes after the first one is pushed: If nature is truly like that, our acts, like those of the dominoes, are wholly determined by natural history and physical laws that we do not control. Nearly all arguments against free will depend critically on determinism. But there is a central problem with determinism: It is clear from physics that determinism in nature is not true. In 1964, theoretical physicist John Bell (1928–1990) proposed relatively simple…

Will Quantum Mechanics Produce the True Thinking Computer?

Quantum computers come with real world problems of their own

Some hope that quantum mechanics can explain human consciousness. Maybe we are all quantum computers but don’t know it? Maybe quantum computers could think like people? There is an odd relationship between the human mind and quantum mechanics, the science of entities like electrons that are too small to be governed by ordinary physics. Some aspects of consciousness appear to be mediated by such elementary particles. Science writer Philip Ball explains, Nobody understands what consciousness is or how it works. Nobody understands quantum mechanics either. Could that be more than coincidence? Quantum mechanics is the best theory we have for describing the world at the nuts-and-bolts level of atoms and subatomic particles. Perhaps the most renowned of its mysteries is…

Quantum Mechanics Shows That Our Universe Has Purpose

Not only can two physically separated particles influence each other, they can influence each other through time

Recent experiments in entanglement of particles in time as well as space show that our entire universe is imbued with final causality within its very fabric. This final causality must come from some source beyond the universe.
