Tertium Organum is a philosophical work by P.D. Ouspensky that explores the concept of a third canon of thought beyond the traditional binary of Aristotelian logic. The book delves into the mysteries of the universe and the nature of reality, using metaphysical and mystical concepts to provide a deeper understanding of the world around us. Ouspensky argues that this third canon of thought is necessary to fully comprehend the complexities of the universe, and provides a key to unlocking the enigmas of the world. The book is a seminal work in the field of philosophy and is considered a must-read for anyone interested in exploring the deeper mysteries of existence.1922. Translated from Russian.
