Science News has two excellent articles on where we are at, part of a just-started ongoing series.
The first,
by Tom Siegfried, follows in many of the footsteps of Douglas
Hofstadter to talk about consciousness and self-referential systems. The
title of "Self as Symbol" gives some hint of where he's headed. And, he
says self-referentiality may actually deepen our eventual understanding
of consciousness rather than acting as a barrier.
Laura Sanders looks at
the neuroscience side of the coin, and what brain studies are telling
us these days. Not too much of high specificity, but we're getting ideas
on how to refine, and in some ways change, our searching.
