Does reality require observers?

Amanda Gefter has an article at Nautilus a couple of you have asked me about: Reality Exists Without Observers? Boooo! The title is an accurate summary of her thesis. Gefter is responding to a book by Vlatko Vedral, where he reportedly argues for a reality that doesn't require observers. In terms of quantum mechanics, Vedral … Continue reading Does reality require observers? →

Does consciousness require biology?

Ned Block has a new paper out, for which he shared a time limited link on Bluesky. He argues in the paper that the "meat neutral" computational functionalism inherent in many theories of consciousness neglect what he sees as a compelling alternative: that the subcomputational biological realizers underlying computational processes in the brain are necessary … Continue reading Does consciousness require biology? →

What physicists believe about quantum mechanics

A few years ago David Bourget and David Chalmers did a follow up survey to the 2009 one polling philosophers on what they believe about various questions. One of them was quantum mechanics, particularly the measurement problem and its various interpretations. Over the decades there have been surveys of physicists themselves on this question, but … Continue reading What physicists believe about quantum mechanics →

Reducing felt experience requires not preemptively dismissing the solutions

Annaka Harris has a new audio book out which she is promoting. I haven't listened to it, but based on the interviews and spots like the one below, it appears that she's doubling down on the conclusions she reached in her book from a few years ago, that consciousness is fundamental and pervasive. https://www.youtube.com/watch?v=nP2swgDVl5M The … Continue reading Reducing felt experience requires not preemptively dismissing the solutions →

Avoiding the structural gaps

A long standing debate in quantum physics is whether the wave function is real. A quick reminder: quantum entities appear to move like waves, including portions interfering with each other. These waves are modeled with the wave function. But once measured, quantum objects manifest as localized points or field excitations. The wave function can't predict … Continue reading Avoiding the structural gaps →

What justifies logic?

Argument terminology used in logic and reasoning

Jacob McNulty has an article at IAI arguing that the foundations of logic can only be found in metaphysics. (Warning: possible paywall. Alternate link.). He describes a problem called “the logocentric predicament," that any attempt to justify logic with logic ends up being circular, risking an infinite regress. He notes that the most common response … Continue reading What justifies logic? →

Fundamental and naturalistic panpsychism

In the art of the Japanese rock garden, the artist must be aware of the "ishigokoro" ('heart', or 'mind') of the rocks.

Nicolas Rouleau and Michael Levin have a new preprint out: Brains and Where Else? Mapping Theories of Consciousness to Unconventional Embodiments. The gist of the paper is that we should be open to seeing consciousness in places other than brains. While I'm onboard with that general premise, they take it to places that don't seem … Continue reading Fundamental and naturalistic panpsychism →
