P.D. Ouspensky believed his "Tertium Organum" to be the third major philosophical synthesis after those of Aristotle and Bacon. The book provides an extended analysis of scientific and occult ideas expressed in terms of higher dimensions. It was originally issued in Russian in 1912, and this is the second, revised edition, translated into English by Claude Bragdon and published in 1922.
