People with online papers in philosophy

Compiled by David Chalmers

This is a list of individuals who have made available online papers in philosophy and related areas. This practice is very much to be encouraged! Note that this list concentrates mostly on academic philosophers, although some scientists and others in related fields are included. If you know of people I should add to this list, please tell me. New papers on the pages listed here are logged daily in Jonathan Ichikawa's philosophy papers log. For other sources of online papers see my directory of online papers on consciousness, and of web resources. Thanks to Ming Tan of Melbourne University for his regular help in updating this directory.
