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)

In last week’s podcast,” our guest host, neurosurgeon Michael Egnor, interviewed philosopher of science Bruce Gordon on “Idealism and the Nature of Reality.” Idealism is the view that “something mental (the mind, spirit, reason, will) is the ultimate foundation of all reality, or even exhaustive of reality” – Stanford Encyclopedia of Philosophy. As Gordon noted in the earlier portion of this podcast, idealism is actually a practical philosophy. It originated with Plato (c. 424–347 BC) but the modern form, which he himself holds, is that of George Berkeley (1685–1753). In Berkeley’s view everything that exists is an idea in the mind of God. Thus, Dr. Egnor asked him what he thinks of panpsychism, the view that everything in the universe…

Why Would a Neuroscientist Choose Panpsychism Over Materialism?

It seems to have come down to a choice between “nothing is conscious” and “everything is conscious”

A really significant change in brain science in recent years has been the gradual acceptance in mainstream science venues of sympathy for panpsychism — the position that everything is conscious to some degree. Leading neuroscientist Christof Koch, for example, explained last month in MIT Reader: But who else, besides myself, has experiences? Because you are so similar to me, I abduce that you do. The same logic applies to other people. Apart from the occasional solitary solipsist this is uncontroversial. But how widespread is consciousness in the cosmos at large? How far consciousness extends its dominion within the tree of life becomes more difficult to abduce as species become more alien to us. One line of argument takes the principles…

Do Bacteria Warn Others While Dying from Antibiotics?

Scientists are learning more about the complex ways bacteria overcome efforts to control them

That’s what we learn from a new open-access paper in Nature titled “Dead cells release a ‘necrosignal’ that activates antibiotic survival pathways in bacterial swarms.” It’s sometimes described as “screams,” but it’s actually a release of chemicals, which amounts to the same thing: a warning to prepare for an onslaught of antibiotics. The scientists also noted another curious factor: The cascade of genes turned on by necrosignals not only protected the surviving swarm from antibiotics, but promoted future resistance to the compounds that killed their comrades. What’s more, the scientists realized that subpopulations of swarm bacteria were genetically variable; some were more susceptible to the antibiotics than others. Swarms of bacteria may collectively cultivate different subpopulations as an evolutionary survival…

Has Science Shown That Consciousness Is Only an Illusion?

Using clever analogies, Philosopher Daniel Dennett argues that consciousness is all smoke and mirrors
British philosopher Papineau recommends taking Dennett’s theories “with a pinch of salt.” American essayist David Bentley Hart is less charitable: “Daniel Dennett’s latest book marks five decades of majestic failure to explain consciousness” Read More ›
