The Internet Encyclopedia of Philosophy (IEP) (ISSN 2161-0002) was founded in 1995 as a non-profit organization to provide open access to detailed, scholarly information on key topics and philosophers in all areas of philosophy. The Encyclopedia receives no funding, and operates through the volunteer work of the editors, authors, volunteers, and technical advisers. At present the IEP is visited by over 500,000 persons per month. The Encyclopedia is free of charge and available to all users of the Internet world-wide. The staff of 30 editors and approximately 300 authors hold doctorate degrees and are professors at colleges and universities around the world, most notably from English-speaking countries.
