The researchers found that “the spread of light across a fractal is governed by different laws in the quantum case compared to the classical case.”

We sometimes forget how far we are from solving the mystery of consciousness. An anecdote from 1994 might help us understand. Picture an utterly boring, pointless conference in Tucson, Arizona, one of whose attendees was an obscure philosopher from Australia, scheduled to give the third talk. And shook everything up: The brain, Chalmers began by pointing out, poses all sorts of problems to keep scientists busy. How do we learn, store memories, or perceive things? How do you know to jerk your hand away from scalding water, or hear your name spoken across the room at a noisy party? But these were all “easy problems”, in the scheme of things: given enough time and money, experts would figure them out. Read More ›
Science journalist and author Anil Ananthaswamy has written a thoughtful piece at New Scientist on the leading models of consciousness and their relationship to quantum mechanics (quantum physics). Are we reaching the point where we can test at least one of them? Ananthaswamy is well qualified to assess the arguments. He is the author of both Through Two Doors at Once (2018) on quantum physics and The Man Who Wasn’t There (2015) on the nature of the self. Models of consciousness that assume that “consciousness isn’t separate from the material reality that physics explains” (materialist or naturalist theories) fall into three general classes, as he explains. Analysts like Tufts philosopher Daniel Dennett and Princeton neuroscientist Michael Graziano argue that consciousness Read More ›
Yesterday, we published a portion of the transcript of the debate between materialist philosopher David Papineau amd neurosurgeon Michael Egnor, in which Egnor explains how, despite early atheism, the practice of medicine led him to believe that there is a God and that the mind is not simply what the brain does. He offered three reasons. Today, here’s a transcript of David Papineau’s reply. Starts, roughly, at 9:00 min: Note: Dr. Papineau is a “physicalist,” a form of materialism according to which “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 Read More ›
Recently, neurosurgeon Michael Egnor debated philosopher David Papineau at Theology Unleashed. Papineau is considered “one of the best defenders of naturalism” (actually, as he admits, physicalism). Egnor talks about how science and the practice of medicine persuaded him that there is a God and that the mind is real. The host is Arjuna and the show is billed as “Eastern theology meets Western skepticism.” What follows is a partial transcript of the first portion, with notes: Michael Egnor: Just as a little background about where I’m coming from, I was raised as a functional atheist, and I was educated as a scientific atheist, so I was an atheist for most of my life. I was a biochemistry major in college, Read More ›
Perhaps accepting the fact that the mind is immaterial may convert the problem from intractable to difficult but solvable in principle.

Neuroscientist Ryota Kanai, founder and CEO of Tokyo-based startup Araya, aims to “understand the computational basis of consciousness and to create conscious AI.” He isn’t sure, he says, if we want AI to be conscious. But, technically, he doesn’t see it as an insurmountable problem: If we can’t figure out why AIs do what they do, why don’t we ask them? We can endow them with metacognition—an introspective ability to report their internal mental states. Such an ability is one of the main functions of consciousness. It is what neuroscientists look for when they test whether humans or animals have conscious awareness. For instance, a basic form of metacognition, confidence, scales with the clarity of conscious experience. When our brain Read More ›
What you think is enabling you to listen with any attention to neuroscientists (your dog, coffee cup, and your toothpaste are not listening to neuroscientists) is something — some of them tell us — we should give up as an illusion.

Finishing the third and final podcast of the series, “Unity of Consciousness,” Walter Bradley Center director Robert J. Marks and Angus Menuge, professor and chair of philosophy at Concordia University, had a look at entrepreneur Elon Musk’s implanted brain chip venture, the Neuralink: https://episodes.castos.com/mindmatters/Angus-Menuge-Episode-3-rev1.mp3 This portion begins at 14:28 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks: Let me end our discussion together by asking you an outlier question. Elon Musk is developing something called Neuralink. It’s a chip which goes into the brain. Its immediate application is going to be for those that are handicapped. It is going to allow them communicate directly to objects that they can’t control normally because of their handicap. Read More ›
In the third podcast of the series, “Unity of Consciousness,” Walter Bradley Center director Robert J. Marks interviews Angus Menuge, professor and chair of philosophy at Concordia University, on unique features of human consciousness, including the fact that our experiences are a unity, despite being scattered across many brain regions and even if our brains are split in half: But now let’s do some thought experiments, as proposed by Oxford philosopher Richard Swinburne: https://episodes.castos.com/mindmatters/Angus-Menuge-Episode-3-rev1.mp3 This portion begins at 04:55 min. A partial transcript, Show Notes, and Additional Resources follow. Angus Menuge: There’s another problem raised by [philosopher] Richard Swinburne: He imagines that he’s going to have an operation where each of his cerebral hemispheres is placed in another person. So Read More ›
In this Bingecast episode, Dr. Robert J. Marks and Dr. Michael Egnor explore the human brain and its relationship to the mind. Is the mind an emergent property of the brain? Is there neurological evidence for the soul? What have brain experiments taught us about free will and the human person? Can you still think in a coma? Show Notes Read More ›
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, they established that one of the implications of quantum mechanics is that consciousness is a “thing”; it exists in its own right. How can we apply that finding to claims for artificial intelligence? https://episodes.castos.com/mindmatters/Mind-Matters-134-Angus-Menuge.mp3 This portion begins at 25:33 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks (pictured): Here is the big AI question: I know that I am conscious. Is there a way we can test for consciousness in others? And if we can, could we apply this test of consciousness in others to artificial intelligence? Can I test Read More ›
If quantum measurements must include consciousness, the dualists are correct, says philosopher Angus Menuge: Consciousness exists in its own right.

Last week, five animated short films competed for Oscar gold, with the top prize going to the emotionally charged “If Anything Happens I Love You.” The short is a bold examination of bereavement as two parents grapple with the violent loss of their young daughter. It’s a worthy winner. However, my own pick didn’t make the shortlist. WiNDUP (2020), written and directed by young creative Yibing Jiang, is also a poignant meditation on parenthood and grief — in this case, for a child in a possibly irreversible coma — as well as a technical gem. Jiang’s company, Unity, uses custom-built software to create shorts in “real-time 3D” on standard computers. Doing without certain tools that animators take for granted today, Read More ›

Blindsight is the remarkable ability of some blind people to sense objects that they cannot actually see. It occurs when the blindness is caused by damage to the main part of the brain that processes visual information (the striate cortex). But the eyes themselves are intact. The eyes continue to see (sensation) but nothing is receiving the messages (perception). Or so we would think, except for this: One of the most contentious discussions in philosophy of mind and neuroscience is the nature of perception as opposed to sensation. How can we perceive objects in our environment? On a deeper level, what do we mean by “perception”? In what ways does perception differ from sensation, if at all? The neurobiology of Read More ›
Neuroscientist Joel Frohlich (pictured) asks us to reflect on the “philosophical zombie.” That’s not the zombie of the late nite frites. It’s an entity that behaves outwardly in every respect like you and me but has no inner experience (think Stepford Wives). Philosopher David Chalmers originated the term in 1996, by way of illustrating why consciousness is a Hard Problem. A powerful computer can crunch through many difficult jobs without any inner life or consciousness. But, Frohlich, who is editor in chief of the science communications website Knowing Neurons, asks, what if we weren’t sure? How would we test that? Trying to determine if a powerful AI is conscious means getting past programming that might enable it to generate plausible Read More ›
