This new edition of the fourth volume of The Dramatic Universe includes corrections to errata found in the previous editions, but is otherwise unchanged and includes no new material. The work can be read without reference to the earlier volumes, b but readers should be aware that many notions particularly Hyparxis, are introduced in previous volumes, where extensive explanations are included. Although Bennett's greatest teacher G.I. Gurdjieff is only briefly referenced, Bennett's argument that the greatest advances in evolution are in the development of Mind, is entirely consistent with Gurdjieff's teaching. Some readers have asserted that many of the arguments that Bennett advances are based on palaeontological research that was accepted at that time but no longer is. This criticism does not refute Bennett's central theme of the Intelligent Guidance of History.
John Godolphin Bennett (8 June 1897 – 13 December 1974) was a British mathematician, scientist, technologist, industrial research director and author. He is perhaps best known for his many books on psychology and spirituality, particularly on the teachings of G. I. Gurdjieff. Bennett met Gurdjieff in Istanbul in October 1920 and later helped to co-ordinate the work of Gurdjieff in England after Gurdjieff's arrival in Paris. He also was active in starting the British section of the Subud movement, and co-founded its British headquarters.
