The relativity of scientism

Symbol for an atom

Philosopher Jonny Thompson has an article up on RealClearScience profiling the views of Mary Midgley: The Three Myths of Scientism. (Warning: the RealClearScience site is pretty ad intensive.) Midgley was a famous critic of views she regarded as scientism, and often sparred with atheist and antitheist Richard Dawkins. As someone who usually takes the scientific … Continue reading The relativity of scientism

Stimulating the prefrontal cortex

(Warning: neuroscience weeds) This is an interesting study getting attention on social media: Does the Prefrontal Cortex Play an Essential Role in Consciousness? Insights from Intracranial Electrical Stimulation of the Human Brain. Ned Block is one of the authors. (Warning: paywalled, but you might have luck here.) The study looks at data from epileptic patients … Continue reading Stimulating the prefrontal cortex

The global playground

(Warning: neuroscience weeds) Stanislas Dehaene recently called attention to a paper in Nature studying the brain dynamics of something becoming conscious. The study supports the global neuronal workspace theory that consciousness involves "bifurcation" dynamics, an "ignition", a phase transition between preconscious and conscious processing. Prior to the transition, the processing is feedforward and fleeting. After … Continue reading The global playground

The right reason to doubt the simulation hypothesis

This weekend, Sabine Hossenfelder did a video and post about the simulation hypothesis, the idea that we might be living in a computer simulation. She dismisses the notion that consciousness can't be a computational simulation, which I think is correct, but then settles on the idea that physics itself can't be simulated, because we have … Continue reading The right reason to doubt the simulation hypothesis

The return of heretical thought?

A nuclear explosion

A couple of weeks ago I highlighted Robin Hanson's ideas about alien civilizations. A big part of Hanson's reasoning involved the Fermi paradox, the question that, if alien civilizations are common, there where is everyone? It seems like Earth should have been colonized long ago. Hanson focused on the number of difficult evolutionary filters life … Continue reading The return of heretical thought?

The safety of nuclear power?

Kurzgesagt takes a look at the number of deaths from nuclear power in comparison with other sources. You might find the actual numbers surprising. Kurzgesagt - in a Nutshell: How Many People Did Nuclear Energy Kill? Nuclear Death Toll I think the video makes an important point. But by focusing exclusively on deaths, it … Continue reading The safety of nuclear power?
