The substitution argument

Diagram of Phenomenal and Functional consciousness

A preprint came up a few times in my feeds, titled: Falsification and consciousness.  The paper argues that all the major scientific theories of consciousness are either already falsified or unfalsifiable.  One neuroscientist, Ryota Kanai, calls it a mathematical proof of the hard problem.  Based on that description, it was hard to resist looking at … Continue reading The substitution argument

The mechanical philosophy and mysterianism

Noam Chomsky published an essay on his web site a few years ago: Science, Mind, and Limits of Understanding.  Chomsky's thesis is that there are areas of reality that science is simply incapable of understanding.  He uses as his principle example, the case of Isaac Newton's understanding of gravity. Chomsky acknowledges that this is a … Continue reading The mechanical philosophy and mysterianism

The spectrum of science to fantasy

Black swans

A question long argued in the philosophy of science is the demarcation problem.  How to we distinguish science from non-science?  Karl Popper famously proposed falsifiability as a criteria.  To be science, a theory must make predictions that could turn out to be wrong.  It must be falsifiable.  Theories that are amorphous or flexible enough to … Continue reading The spectrum of science to fantasy

Predictions and retrodictions

I've often noted here the importance of predictions, both in terms of our primal understanding of reality, such as how to get to the refrigerator in your house, or in terms of scientific theories.  In truth, every understanding of reality involves predictions.  Arguably a fundamental aspect of consciousness is prediction. Of course, not every notion … Continue reading Predictions and retrodictions

The role of beauty and simplicity in scientific theories

In the post on Copernicus earlier this week, I noted that his heliocentric theory, right from its initial publication, was hailed as far more mathematically elegant than the Aristotelian / Ptolemaic system, which was taken as the canonical model of the universe at the time.  But while everyone hailed Copernican mathematics, virtually no one accepted … Continue reading The role of beauty and simplicity in scientific theories

The problems with post-empirical science

Jim Baggott has a pretty good piece at Aeon on the problems with post-empirical science.  I've highlighted Baggott's views before.  Along with others like Sabine Hossenfelder and Peter Woit, he calls attention to a serious issue in physics, the rising acceptance of theories that show little promise of being testable in the foreseeable future.  In … Continue reading The problems with post-empirical science
