Will We Soon Be Able to Test Theories of Consciousness?

Proponents of two leading theories of consciousness are trying to develop tests for their models, in a hitherto baffling field

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 ›

Can LSD Help Us Understand the Mind–Brain Relationship?

Is the mind generated by the brain or does the brain merely focus the mind on the current scene? An experiment sheds some light

In a fascinating article inThe Guardian titled “Acid test: scientists show how LSD opens doors of perception,” science editor Ian Sample discusses recent research on the mechanism by which LSD alters the brain and the mind. He begins by quoting Aldous Huxley (1894–1963) who noted that LSD “lowers the efficiency of the brain as an instrument for focusing the mind on the problems of life.” Remarkably, recent work in neuroscience supports Huxley’s view. The research, conducted at Cornell University, confirms what has been called the Rebus model of psychedelics. Rebus is a rough acronym for “relaxed beliefs under psychedelics”; the model proposes that the brain is essentially a prediction engine for daily life. In this model, the brain processes information Read More ›

Bruce Gordon on the Meaning of Neuroscience (Part III)

In this third and final episode with Dr. Bruce Gordon, host Michael Egnor picks Gordon’s brain on the overlaps between historical metaphysical perspectives and modern neuroscience. What does St. Thomas Aquinas have to say about metaphysical realities, and how does that compare to Plato’s idealism? Who is right? And what can near-death experiences and other phenomena tell us about the Read More ›

A Physicist and Philosopher Examines Panpsychism

Idealism says everything is an idea in the mind of God. Panpsychism says everything participates in consciousness (thus is not just an idea)

Bruce Gordon thinks that, for a thing to be conscious, there must be something that it “is like” to be that thing. Can panpsychism demonstrate that?

Bruce Gordon on Idealism and Quantum Physics (Part II)

Continuing their discussion on idealism and the nature of reality, Michael Egnor and Bruce Gordon delve into the mystifying realm of quantum physics. What does quantum physics say about the nature of our reality? And how does this relate to philosophical theories about the world around us? Show Notes Additional Resources

Bruce Gordon On Idealism and the Nature of Reality (Part I)

What is the fundamental nature of reality? Is reality more like a mind, or more like a physical object? What is panpsychism? Tune in to this week’s podcast to hear guest host Michael Egnor interview Dr. Bruce Gordon on idealism. Gordon explores different varieties of idealism, the insights of past philosophers, and the theories of contemporary thinkers. Show Notes Additional Read More ›

Has Neuroscience “Proved” That the Mind Is Just the Brain?

This is hardly the first time that bizarre claims have been made for minimal findings. In neuroscience, materialism is the answer only if you don’t understand the questions.

Last month, materialist neurologist Steven Novella made a rather astonishing claim in a post at his Neurologica blog: A recent open-access study of learning and decision-making in mice shows that the human mind is merely what the human brain does. That’s a lot for mice to prove. In the study, the mice were trained to choose holes from which food is provided. Their brain activity was measured as they learned and decided which holes were best. The research looks specifically at quick and intuitive decision-making vs. decision-making that is slower and involves analysis of the situation. The investigators found that analysis-based decisions in the mice involve brain activity in the anterior cingulate cortex, which is a region of the brain Read More ›

Does Physics Today Point to Mind Rather Than Matter Only?

A cosmopsychist looks at the universe, God, and free will

Bernardo Kastrup tells Michael Egnor that he does not think God is self-reflective. That, he thinks, is a unique job for humans.

Does the Moon Exist if No One is Looking at It?

Is our physical reality purely subjective or is it objective? Why has materialism been around for so long? Do we have free will? Dr. Michael Egnor and Dr. Bernardo Kastrup discuss physics, idealism, materialism, and free will. Show Notes Additional Resources
