There's lots of cool things going on in the PEL Not School discussion groups. To entice those of you that are interested in emergence to come check things out, I've proposed reading and discussing a short, interesting essay by the physicist P. W. Anderson called “More is Different: Broken Symmetry and the Hierarchical Nature of Science”. The essay itself is was originally published in 1972 in Science and is a classic in the discussions of emergence. You can get a PDF copy of the original article or get it along with a bunch of other interesting articles included in recently published collection Emergence: Contemporary Readings in Philosophy and Science (Bradford Books) edited by Mark A. Bedau and Paul Humphreys.
I plan to have a single discussion over Skype or somesuch concerning the reading at a time to be determined in mid/late December.
Come check it out!
