2013 Reprint of 1922 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. In 1920 "Tertium Organum" was published in the USA; Claude Bragdon one of the people responsible for translating and publishing the English edition stated at the time; 'In naming his book "Tertium Organum" Ouspensky reveals at a stroke that astounding audacity which characterizes his thought throughout... Such a title says, in effect: "Here is a book which will reorganize all knowledge. The "Organon" of Aristotle formulated the laws under which the subject thinks; the "Novum Organum" of Bacon, the laws under which the object may be known; but the Third Canon of Thought existed before these two, and ignorance of its laws does not justify their violation. "Tertium Organum" shall guide and govern human thought henceforth. "'
