Tertium Organum, or the third canon of thought, gives a new view of the perception of the world. In Tertium Organum, the author offers the shift of the paradigm and speaks of higher consciousness, or the consciousness of the fourth dimension, the domain for the personal development of the human, the ability to control your emotions and actions. The book is inspired by the teachings of Gurdjieff about the Fourth Way. According to this philosophy, there are three ways of self-development: the Way of the Fakir (developing physical body), the Way of the Monk (dealing with the emotions), and the Way of the Yogi (mastering the mind). Yet, there is another way – the Fourth Way that enables a human being to combine all three ways and live in harmony of body, spirit, and mind. Ouspensky applies this theory to the study of time and space, where he defines time as the fourth dimension of space and personality. The book's name is the allusion to the Organum of Aristotle, which laid the basis for the development of science, and the Organum Novus by Francis Bacon, who defined knowledge as only those facts that can be checked empirically.

The author combines advanced science and math with Eastern mysticism, symbols, art and Western spiritual traditions to create one of the most unique and interesting books one is likely to encounter. Ouspensky points the reader toward higher dimensional realities -- the fourth dimension and above -- while revealing how we can, in a sense, overcome our limited human perceptions that block our access to these higher worlds or planes of existence. An original and brilliant work that waits patiently to be discovered by modern and intelligent thinkers.

Tertium Organum, the first of Ouspensky's major works, was originally published in 1912 in St. Petersburg, and a second revised edition appeared four years later in Petrograd. Nicholas Bessaraboff brought a copy of the second edition with him when he emigrated to the United States before the Russian Revolution of March 1917. The book was translated into English by Nicholas Bessaraboff and Claude Bragdon and published by Bragdon's Manas Press in 1920. At that time no one in the United States knew whether Ouspensky had survived the First World War, the Russian Revolution of March 1917, or the Bolshevik seizure of power later that year. In fact, Ouspensky had decided to leave Russia for a neutral country in 1916, but instead he travelled south to join Gurdjieff for a while. In 1920 Ouspensky made his way from Ekaterinodar and Rostov-on-Don to Odessa and thence to Constantinople, where he received the news that Tertium Organum had been translated into English and published in America by Bessaraboff and Bragdon. On his way back to Russia from India and Ceylon in the autumn of 1914 after the outbreak of the First World War, his roundabout route had taken him first to London where he had made arrangements for the publication of his books when the war was over. But six years later when he found that Tertium Organum had already been translated and published in the United States, he accepted the situation and wrote a preface for the second American edition in 1922. In August 1921 Ouspensky moved to London and for the next twenty years worked with a number of his students on the English translations of A New Model of the Universe, Fragments of an Unknown Teaching (the working title of In Search of the Miraculous), Strange Life of Ivan Osokin and Tertium Organum. The translation of Tertium Organum was undertaken by Madame E. Kadloubovsky, from the second Russian edition, and a substantial part was approved by the author. In 1947, at the time of his death, the translation was incomplete but Mme Kadloubovsky decided to finish it, having already received careful directions from the author. The new translation was first lithographed in Cape Town, South Africa, in an edition of only twenty-one copies by Fairfax Hall at his private press, the Stourton Press. Later in 1961, an abridged version was hand-set with the help of students interested in Ouspensky's ideas - in the ten-point type designed for the press by Eric Gill. Neither this edition of one hundred copies nor the earlier edition were offered for sale.

2013 Reprint of 1931 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. In this classic work, Ouspenky analyzes certain of the older schools of thought from the East and the West, connecting them with modern ideas and explaining them in light of the most recent discoveries and speculations in newer schools of philosophy and religion. In the course of his research he integrates the theories of relativity, the fourth dimension and current psychological theories. The book closes with a consideration of the sex problem from the perspective of sex in relation to the evolution of man toward superman.

This book recounts P. D. Ouspensky's first meeting and subsequent association with George Gurdjieff. It is widely regarded as perhaps the most comprehensive account of Gurdjieff's system of thought available. Many followers regard it as a "fundamental textbook" of Gurdjieff's teachings and it is often used as a means of introducing new students to Gurdjieff's system of self-development.

"A brilliant fantasy." -- Manchester Guardian. What would you do if you could re-live your life? In his only novel, occultist P. D. Ouspensky expands upon his concept of eternal recurrence, telling of a man who travels back in time and attempts to correct the mistakes of his schooldays and early manhood, including his romantic misadventures. Set in Moscow and Paris, the story served as an inspiration for the movie Groundhog Day.
