Quantum processes are helpful to know about when we hear a gimcrack new theory that dismisses or explains away consciousness. We know it can’t be that simple.

If it’s true that we can’t trust the reasoning skills of our evolved brains to arrive at a correct answer, we are in no position to evaluate Harris’s own thesis.

Recent findings suggest that some things we take for granted in human civilizations are much older than thought. Now, these findings are provisional but they are worth looking at: The owl stones from 5,500 and 4,750 years ago may be children’s art: But new research suggests the palm-sized plaques decorated in geometric patterns and with two engraved circles at the top might be the work of children. Numbering in the thousands and made from slate, the owl-like objects – previously dated the stone objects to be between 5,500 and 4,750 years old – may be “the archaeological trace of playful and learning activities carried out by youngsters,” according to the team of Spanish researchers behind the new study… They suggest Read More ›
Recent research shows that one in five people who survive cardiopulmonary resuscitation (CPR) after a heart attack ‘may describe lucid experiences of death that occurred while they were seemingly unconscious and on the brink of death”: Led by researchers at NYU Grossman School of Medicine and elsewhere, the study involved 567 men and women whose hearts stopped beating while hospitalized and who received CPR between May 2017 and March 2020 in the United States and United Kingdom. Despite immediate treatment, fewer than 10% recovered sufficiently to be discharged from hospital. Survivors reported having unique lucid experiences, including a perception of separation from the body, observing events without pain or distress, and a meaningful evaluation of life, including of their actions, Read More ›
Recently, Walter Bradley Center director Robert J. Marks interviewed human dignity advocate Wesley J. Smith on the seeming science fiction question of “Can a computer be a person?” (November 10, 2022, podcast 212): https://mindmatters.ai/wp-content/uploads/sites/2/2022/11/Mind-Matters-212-Robert-Marks.mp3 Here are a couple of highlights: About Alexa: Wesley J. Smith: I was going to ask you about Alexa because she may come on in behind me. Of course, she’s not a she. That’s just a female-sounding voice. But I can ask, we’ll call her A, so she doesn’t come on, what time it is and she’ll tell me immediately. I can tell her to play certain music and she’ll play it immediately. How does that operate? I mean, she’s not… That program is not intelligent, Read More ›
Remember Francis Crick (1916–2004) and The Astonishing Hypothesis (1994)?: “You, your joys and sorrows, your memories and ambitions, your sense of personal identity and free will are, in fact, no more than the behaviour of a vast assembly of nerve cells. As Lewis Carroll’s Alice might have phrased it: ‘You’re nothing but a pack of neurons’.” Crick focused on the brain region known as the claustrum as closely tied to consciousness. According to University of Maryland medical researchers, he thought of it as the “seat of consciousness.” Now, the very concept of a “seat of consciousness” assumes that consciousness is a material thing that needs a seat. In other words, consciousness must be found specifically in one place and not Read More ›
Classical Greek mythology featured the “centaur,” a creature that was half human, half horse. Neuroscientist and horse trainer Janet Jones, author of Horse Brain, Human Brain: The Neuroscience of Horsemanship (Trafalgar Square, 2020), tells us that there is a truth behind the myth (as so often). In what amounts to a “neurobiological miracle,” the horse — a prey animal — and the human — a predator — can learn complete neurological co-operation to perform complex feats that neither can manage alone. How complex are these equestrian feats? Horse-and-human teams perform complex manoeuvres in competitions of all sorts. Together, we can gallop up to obstacles standing 8 feet (2.4 metres) high, leave the ground, and fly blind – neither party able Read More ›

Readers of Mind Matters News have likely heard of the iconic Turing test. Computer pioneer Alan Turing famously invented a test to determine whether a program could pass as a human. The gist is, if a program can fool human testers into believing it is a human, then the program is intelligent. Not everyone is convinced. Thing is, it doesn’t take much to fool us humans! Take Eliza , a program of only a few hundred lines, written in the 60s, which fooled many people into believing it was a real human therapist. But what if we flip the Turing test on its head? Instead of a test where a program tries to pass as human, we use a test Read More ›
In a recent episode at Mind Matters News podcasting, “Can a computer be a person?” (November 10, 2022), Robert J. Marks and Wesley J. Smith discussed that in connection with Marks’s new book, Non-Computable You: https://mindmatters.ai/wp-content/uploads/sites/2/2022/11/Mind-Matters-212-Robert-Marks.mp3 Some excerpts: Wesley J. Smith: Let me ask the question in a different way. Can an AI ever be irrational? Robert J. Marks: Yes. Irrational in the sense of being irrational from the point of an observer. A classic example, and this happened a number of years ago, was that the Soviets during the Cold War developed a high technology to decide whether the US was being attacked by… I’m sorry, whether the Soviet Union was being attacked by the United States. And so Read More ›
At Psychology Today, we read a bold and simple claim about the evolution of consciousness: “A type of information processing called unlimited associative learning (UAL) may be necessary and sufficient for very basic sentience.” The article by University of Toronto psychiatrist Ralph Lewis begins on a very self-assured note: Nothing in biology makes sense except in the light of evolution. The gradualism of evolution has explained and dissolved life’s mysteries—life’s seemingly irreducible complexity and the illusion that living things possess some sort of mysterious vitalizing essence. So, too, evolution is likely to be key to demystifying the seemingly inexplicable, ethereal nature of consciousness. Ralph Lewis, “Learning May Be the Key to the Evolution of Consciousness” at Psychology Today (November 3, Read More ›
The Van Gogh Test for sheer creativity? Thursday night at COSM presented a live, in-person interview with Federico Faggin, the Italian physicist and computer engineer who co-won the prestigious Kyoto prize in 1997 for helping develop the Intel 4004 chip. Faggin was interviewed by technology reporter Maria Teresa Cometto, who asked him to regale the audience with tales about helping to design early microchips. Eventually Faggin recounted a time when he was “studying neuroscience and biology, trying to understand how the brain works,” and came upon a startling realization: And at one point I asked myself, “But wait a second, I mean these books, all this talk about electrical signals, biochemical signals, but when I taste some chocolate, I mean Read More ›
In recent decades, it has become possible to revive people in various stages of death who, at one time, would have died, leaving no testimony. The news from AWARE II won’t please total materialists at all: The study authors conclude that although studies to date have not been able to absolutely prove the reality or meaning of patients’ experiences and claims of awareness in relation to death, it has been impossible to disclaim them either. They say recalled experience surrounding death now merits further genuine empirical investigation without prejudice. NYU Grossman School of Medicine and NYU Langone Health, “Lucid Dying: Patients Recall Death Experiences During CPR” at Cision PR Newswire (November 6, 2022) Why not assume that those people were Read More ›

In a classic piece at Nautilus, novelist Cormac McCarthy (b. 1933) — author of, among other novels, All the Pretty Horses (1992) and The Road (2007) — muses on the origin and nature of the unconscious mind. As we might expect from a novelist, it’s not his grand theory that is of much use at all. His grand theory is that “the unconscious is a machine for operating an animal,” which makes no sense. He adds, “All animals have an unconscious. If they didnt they would be plants.” How does he know that pond hydras, for example, have an “unconsciousness” but maple trees don’t? Well, he doesn’t. And yet, he also offers shafts of light that make the “Hard Problem Read More ›
A recent study finds that Eurasian jays can pass a version of the “Marshmallow test” and that the smarter jays had the greatest self-control. The original Marshmallow test tested children to see if they could resist eating one marshmallow if they were offered two later. So enterprising researchers decided to try it on smart birds: To test the self-control of ten Eurasian jays, Garrulus glandarius, researchers designed an experiment inspired by the 1972 Stanford Marshmallow test — in which children were offered a choice between one marshmallow immediately, or two if they waited for a period of time. Instead of marshmallows, the jays were presented with mealworms, bread and cheese. Mealworms are a common favourite; bread and cheese come second Read More ›
Some children have half of their brains removed (hemispherectomy) to control massive seizures that would otherwise destroy the child’s whole brain. Specialists were surprised that the children functioned fairly normally — certainly compared to what would have been expected. A recent study of post-hemispherectomy patients has provided dramatic evidence of rewiring: An unprecedented study of brain plasticity and visual perception found that people who, as children, had undergone surgery removing half of their brain correctly recognized differences between pairs of words or faces more than 80% of the time. Considering the volume of removed brain tissue, the surprising accuracy highlights the brain’s capacity — and its limitations — to rewire itself and adapt to dramatic surgery or traumatic injury. The Read More ›
Since Part 1 of this article was served up, have you experienced food and drink with greater awareness of flavor? Part 1 laid out the elements of flavor, including the smell, taste, texture, and mouth feel of foods and drinks. Smell delivers 80% of what we experience as flavor, coming from the thousands of sensory nerves in our noses detecting individual molecules. From the tongue comes taste sensations of sweet, salty, sour, bitter, and umami (savory). Flavor is like a dynamic 3-D hologram, a multi-dimensional composition of sensory inputs fluctuating in real-time, all delivered as data to the brain for final processing. Flavor makes eating fun! The Computation of Yummy The complicated and integrated systems of smell, taste, and other Read More ›
