What about subjective experience implies anything non-physical?

Mary's room is a classic philosophical thought experiment about consciousness.  The Wikipedia article on what's called the knowledge argument quotes Frank Jackson, the originator of the argument, as follows: Mary is a brilliant scientist who is, for whatever reason, forced to investigate the world from a black and white room via a black and white … Continue reading What about subjective experience implies anything non-physical? →

Recommendation: The Stars Are Legion

Occasionally on this blog, when pondering the far future, I've pushed back on the idea that the long term fate of civilization is to be machine robotic type life, instead noting that a truly advanced civilization would instead be engineered life, that it would make a lot more sense for its "machines" to be biological systems.  Admittedly, … Continue reading Recommendation: The Stars Are Legion →

What do scientific theories actually tell us about the world?

One of the things that's exciting about learning new things, is that often a new understanding in one area sheds light on what might seem like a completely separate topic.  For me, information about how the brain works appears to have shed new light on a question in the philosophy of of science, where there has long … Continue reading What do scientific theories actually tell us about the world? →

Arrival, the shape of aliens, and bridging the communication barrier

Split brain does not lead to split consciousness – University of Amsterdam

I've talked before about Roger Perry's famous split-brain patient experiments.  Patients with severe epileptic seizures used to undergo a collosotomy, a procedure to cut the connections between the left and right hemispheres of their cerebrum.  It often helped alleviate their symptoms and, remarkably, the patients afterward remained mentally functional, at least to outside appearances. Each hemisphere … Continue reading Split brain does not lead to split consciousness – University of Amsterdam →

Two brain science podcasts worth checking out

As my long time readers will know, I'm very interested in the mind, and my preferred way to explore it is through science, notably neuroscience or cognitive psychology, or with science oriented philosophy.  With that in mind, I want to call your attention to a couple of podcasts I've been following for a while. The … Continue reading Two brain science podcasts worth checking out →

America’s long path to universal voting rights

My memory of what I learned in early grade school about the history of American voting rights went something like this.  Prior to 1776, we were ruled by the king of Great Britain.  He was a tyrant who oppressed us with taxation without representation, so we rebelled and set up a democracy.  (UK readers, I see … Continue reading America’s long path to universal voting rights →
