Abstract
This contributed-papers volume is the first volume of essays from the PSA 2008 program. The vast majority of the work in putting together this volume fell to the program committee. The members of this committee began the adjudication process with over 200 submitted papers and went through two rounds of selection, first for the program and then for this volume. Throughout, they all worked diligently and in good humor. So, I would like to thank Ken Aizawa, Rachel Ankeny, Davis Baird, Paul Bartha, Anjan Chakravartty, Hasok Chang, Sharyn Clough, Carla Fehr, Peter Godfrey-Smith, Brad Monton, Mark Risjord, Laura Ruetsche, Kyle Stanford, Friedrich Steinle, and Peter Vranas.
