Quantum Physics Axed Materialism. Many Hope the World Won’t Know

Philosophy of Mind, Physics}

Quantum mechanics, which developed in the early twentieth century, has been a serious blow to materialism. There is no way to make sense of it if immaterial entities like information, observation, or the mind are not real. Theoretical physicist Sabine Hossenfelder struggles against the effects of this fact. In a recent video, she asks, “Does Consciousness Influence Quantum Effects?” (November 19, 2022) She asks, why did some physicists like von Neumann and Wigner think that consciousness is necessary to make sense of quantum mechanics, and can consciousness influence the outcome of a quantum experiment? (0:33) Well, they had good reason. Any effort to exclude consciousness from reality fails. Hossenfelder, a hostile witness, kindly offers an example from the work of Read More ›

Does Superdeterminism Resolve Dilemmas Around Free Will?

Philosophy of Mind, Science}

The conventional view of nature held by materialists, who deny free will, is that all acts of nature, including our human acts and beliefs, are wholly determined by the laws of nature, understood as the laws of physics. We cannot be free, they assert, because all aspects of human nature are matter, and the behavior of matter is wholly determined by physical laws. There is no “room” for free will. It’s noteworthy that physicists who have studied determinism in nature (specifically, in quantum mechanics) have for the most part rejected this deterministic view of free will and implicitly (if not explicitly) endorsed the reality of free will. There are two reasons for this. First, experiments that have followed from the Read More ›

Quantum Physics: Is Everything Determined? Egnor vs. Papineau

Philosophy, Science}

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 Read More ›

“Spooky Action at a Distance” Makes Sense—in the Quantum World

Science}

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. The discussion turned to why Albert Einstein, a brilliant but orderly mathematical thinker, did not really like quantum mechanics at all and what we should learn from that: https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The discussion of Einstein and “spooky action at a distance” (his way of describing quantum particles’ behavior) starts at approximately 27:45. The Show Notes and transcript follow. Excerpts from the transcript: Robert J. Marks: Albert Einstein didn’t like quantum mechanics or certain aspects of quantum mechanics. Dd he die thinking that quantum mechanics was a fluke? Enrique Blair (pictured): That’s an Read More ›

A Materialist Gives Up on Determinism

_{Evolutionary biologist Jerry Coyne undercuts his own argument against free will by admitting that quantum phenomena are real} _{Michael Egnor

Philosophy of Mind, Science}

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 Read More ›

Why is Bell’s Theorem Important for Conservation of Information?

Information Theory, Mathematics}

Proving a negative is difficult. Think about it. For example, demonstrating that there are no leafy green crows is hard to do without exhaustively examining every crow in existence. On the other hand, proving there are no crows naturally emblazoned with the text of the King James Bible is a bit easier to do. Proving a negative is possible if the extremes are large enough. Such as result is known as a no-go theorem. One of the most profound no-go theorems can be found in quantum physics. Physicist John Bell (1928–1990) proved — entirely from first principles — that there is a fundamental difference between how particles interact classically compared with how they interact within quantum physics. In classical physics, Read More ›
