The Philosopher's Annual attempts to select the ten best articles published in philosophy the previous year. Impossible? Yes. By attempting the impossible this collection calls attention to truly exceptional critiques from the philosophical field. This is the 22nd volume of the series, collecting outstanding work from the philosophy literature of 1999. Each year the members of the distinguished nominating board are asked to name three papers that most impressed them from the literature of the previous year. No limitations are placed on sources from which articles may be nominated, on subject matter, or on mode of treatment. The process delivers a diverse collection of engaging, high caliber work that stands as a valuable sample of contemporary work in philosophy.
