A New Theory of How Consciousness Evolved
This article was a little confusing for me. When I read "consciousness," I think of private, subjective experience—qualia. This meaning of consciousness is a very hard problem indeed, and any new theory is bound to be interesting. (See Chalmers for a great summary: <a href="http://consc.net/papers/facing.html" rel="nofollow">http://consc.net/papers/facing.html</a>) But the article seems to be talking about meta-cognition, not conscious experience. Meta-cognition is interesting in its own right I suppose, but far less so than what I normally think of as consciousness.
