The Internet Encyclopedia of Philosophy (IEP) (ISSN 2161-0002) was founded in 1995 to provide open access to detailed, scholarly, peer-reviewed information on key topics and philosophers in all areas of philosophy. The Encyclopedia receives no funding, and it operates through the volunteer work of the editors, authors, volunteers, and technical advisers. The Encyclopedia is free of charge and available to all users of the Internet worldwide. The staff of 30 editors and approximately 300 authors hold doctorate degrees and are professors at universities around the world. There are over 8.2 million unique visitors every year (unique in the sense that someone who views three articles one day, and two articles the next month, is counted as one visitor).
