A completely mind-blowing dose of non-fiction. Although dated, I cannot find anything more modern online or otherwise that refutes his reasoning. That said, this book involves a lot of reasoning that would be difficult, if not impossible, to support factually. Well grounded though, I can't wait to see how deep he can go...

...finally finished this work. I won't attempt to summarize the depth of what is covered in this book. I will only say that if you are a "thinker", constantly searching for mor

Stunning, Wondrous and Life Transforming

There are no words to describe the real import and content of this book, nor to remotely intuit the many dimensions of reality that its ideas are extended too. Many hidden dimensions of life and connection with the world of true causes, of which we as mankind? are not even dimly aware. It seems mankind (aka consciousness) has settled instead for the world of the finite, the phenomenal and the positivistic and Ouspensky clearly shows in a very limpid and pe

Peter D. Ouspensky (March 4, 1878–October 2, 1947), (Pyotr Demianovich Ouspenskii)a Russian philosopher,who invoked euclidean and non-euclidean geometry in his discussions of psychology and higher dimensions of existence. His first book, The Fourth Dimension, appeared in 1909; his second book, Tertium Organum, in 1912; and A New Model of the Universe in 1931. This last wo

This book is all that and so much more. Just a pure dive into metaphysics and paranormality, and what makes them a reality. The logical reasoning the author uses throughout this book is sound, and I cannot refute his arguments. I can only agree in amazement.
The author focuses on space and time, and how they are REALLY related, and all the derivations of such a relationship. Mind you, he looks at them from a purely UN-positivistic point of view,

Brilliant, mind-bending piece about nature of the world and consciousness. It's a must read challenge for all of the materialist science-believers that have fallen into the one-dimensional limited way of thinking and observing the world through the matter only. Ouspensky is succesfully showing the flaws of the positivistic, exact, science and philosophy by offering another, deeper way of thinking outside of the box.

I can sum up my impression of this book by quoting a sentence from it: "And truth itself is motion, and can never lead to arrestment, to the cessation of search."

This book, written in 1920, is timeless. It compels the reader to question, to disagree, to pursue. It is also a tool for measuring one's understanding of new concepts...opening the door for something more. I first read this book about 20 years ago, and I am amazed by my growth in consciousness, in awareness. What appeared obscure, the

Great beginning, I liked the author clarity, his reasoning and the ways he leads the reader through complex geometry concepts. However, he lost me half-way when he introduced the snail and its one-dimensional vision. Maybe it is to be taken in the particular context of the turn of the 1900’s when spirituality was very present in the mind of most scientists involved in the development of exact sciences, but it makes it a little challenging to accept by today’s metrics.

How many times will I allow a Russian Theosophist to break my heart?

I followed his paces so faithfully! He measured his stride so! He spoke to me of his affairs with Kant and with Consciousness.

Ultimately, he believes we are all imperfectly-understanding emanations of the Cosmic Conscious... or of the First Intelligence... call Him what you will.

I still insist that he is the better of Edwin A Abbott (of Flatland acclaim).

Awesome book. Never knew that the beyond can be deduced from philosophy and logic, and that too in such a beautiful manner. And the application of maths was just wow. Ouspensky used analogies very nicely. This book introduced me in much details to the world of beyond world

Be very careful with this book. It will take you into a dangerous labyrinth that if you do not take precautions will trap you. He presents a grand problem, The Kantian Problem, but then takes a very wrong road to its resolution.

This book opened my mind like a crowbar opening a locked lid. It took lots of pressure but the sudden snap as my mind finally opened has changed my view of life, the world and the universe.

“Thus space and time, defining everything that we cognize by sensuous means, are in themselves just forms of consciousness, categories of our intellect, the prism through which we regard the world—or in other words space and time do not represent properties of the world, but just properties of our knowledge of the world gained through our sensuous organism. Consequently the world, until by these means we come into relation to it, has neither extension in space nor existence in time; these are properties which we add to it.” 0 likes
“We do not comprehend all these matters quite clearly, but in general it is plain that we think in space and time by perceptions TERTIUM ORGANUM ' only; but by concepts we think independently of space and time.” 0 likes
