The Fourth Way (1957) is a book about the Fourth Way, a system of self-development as introduced by Greek-Armenian philosopher G.I. Gurdjieff. It is a compilation of the lectures of P. D. Ouspensky at London and New York City between the years 1921 through 1946, published posthumously by his students in 1957. The term "The Fourth Way" has also come to be used as a general descriptive term for the body of ideas and teachings which Gurdjieff brought to the west from his study of eastern schools.
