Is reality an illusion? If so, does it matter?

Donald D. Hoffman, a psychologist at the University of California, Irving, has been getting a lot of attention recently for his views, that evolutionary evidence indicates that reality is an illusion, that the only thing that exists are conscious minds. This is a modern version of an ancient concept, called idealism.  The earliest writings about … Continue reading Is reality an illusion? If so, does it matter?

The unavoidable complexity of morality

I've written before on why science can't determine morality.  This isn't a particularly controversial position (even if many of Sam Harris or Michael Shermer's followers find it so).  No one seems to have found an intellectually rigorous answer to David Hume's is/ought divide, that you can't derive an ought from an is.  To logically determine … Continue reading The unavoidable complexity of morality

The power of symbolic thought

One of the things I've pondered a few times on this blog is our ability to recognize another intelligence, such as an extraterrestrial intelligence.  On the face of it, this seems straightforward.  Do they form societies, use technology, manipulate their environment, and overall show signs of intelligence? Except an alien intelligence may be so different from … Continue reading The power of symbolic thought

Crash Course takes on philosophy

I've featured Crash Course videos before.  The Green brothers (and collaborators such as Phil Plait) manage to take various subjects such as history, astronomy, politics, biology, and others many might find dry and boring, and make them interesting.  Each episode is relatively short (usually under 15 minutes) but cover a lot in that time, edited to move along at a hyper … Continue reading Crash Course takes on philosophy

Panpsychism and definitions of “consciousness”

Disagreeable Me asked me to look at this interesting TED talk by Professor Mark Bishop. http://www.youtube.com/watch?v=qUNHyPFvUWc The entire talk is well worth the time (20 minutes) for anyone interested in consciousness and the computational theory of mind, but here's my very quick summation: The human mind, and hence consciousness, is a computational system. Since animal … Continue reading Panpsychism and definitions of “consciousness”
