5.0 out of 5 stars A Must Read for Curious People Involved in Helping People Change
Reviewed in Australia on 6 April 2025
Format: Hardcover
A Fascinating and Illuminating Book.
This is such a big topic to get your head around but the author does a great job in writing in a clear and straight forward way. I read this book because as a business coach trained in the ontological, systemic team and mindfulness traditions, I wanted to learn about complex systems in different forms and was intrigued (after listening to Theise interviewed) about his perspective, given his training as a pathologist. What I enjoyed most was his perspective - as a medical practitioner steeped in the scientific tradition but not a slave to it - he offers other important perspectives such as Eastern philosophies and challenges some of the deeply held beliefs we have inherited from the scientific tradition, and also highlights where science has been useful. Reading the book, with various detours with Chat GPT, has given me a greater felt sense about how we are all connected, that life is unpredictable and left me in awe of the ability of living systems to adapt and change.

5.0 out of 5 stars a good primer on complexity theory
Reviewed in the United States on 16 June 2023
Format: KindleVerified Purchase
I have a crush on complexity theory. It is the antidote for a childhood steeped in the simplistic and rigid platitudes of organized religion. It doesn’t try to explain the world, giving people a false sense of certainty and superiority. It explores the underlying dynamics of living systems, which are unpredictable by nature. In our lives, we can see patterns and pursue a direction but the outcomes are determined by countless elements that are beyond what we do. As mysterious as this seems, we see examples of it all the time (breakout moments for actors and artists, how candidates as oppositional in nature as Obama and Trump can both be elected, and when music videos go viral). This book extends complexity theory into all the layers of scientific analysis, from the subatomic to the metaphysical. It’s interesting, wise, and also easy to read. In other words…a good book.

In today's era, exercising caution and vigilance has become essential when engaging with AI.
I am referring to Artificial Information. As we venture into the vast expanse of limitless information, it is imperative that we maintain confidence in the authenticity of our sources. Having delved into the profound insights of "Notes On Complexity: A Scientific Theory of Connection, Consciousness, and Being" by esteemed Pathology Professor Dr. Neil Theise, I can wholeheartedly assure truth-seekers that they are embarking on a secure intellectual journey.
This book navigates intricate subjects such as consciousness, quantum foam, randomness, chaos, and complexity, which inherently carry the risk of ensnaring a broader readership within a labyrinth of convoluted and perplexing language. Yet, this very aspect stands as a testament to the book's remarkable potency. Theise, from the outset, candidly reveals his lifelong passion for amassing captivating facts and theories about the world, a passion that resonates throughout with his erudite and eloquent articulacy of these concepts.
This is a must read.

Starting with basic scientific empirical principles and delving all the way into quantum mechanics and Godelian math, this book is a quick and accessible read to complexity theory. What I appreciate about this book is that it is cohesive: each part makes sense about the next part, which is hard to do in an argument that can easily be waylaid by claims of being too "woo". I really like this authors style and would read again.

I love this book, I've read it a couple times and will read it again as it contains so much to reflect on. The first reading through gave me hope for what seems to be a chaotic and complicated life, which can be overwhelming, but reading about the complexities that life experiences bring and the randomness brought me comfort. The second time the hope transmuted to appreciation for all experiences even though many are uncomfortable they offer something that brings a greater sense of consciousness and being a part of the whole, we all matter, we all have something to offer and it's more than we will ever comprehend.

4.0 out of 5 stars Grat hourney; disappointing end
Reviewed in the United Kingdom on 11 May 2025
Format: KindleVerified Purchase
Most of this work is a brilliant overview of complexitytheory and quantum mechanics presented in clear and comprehensible language, with the profound implications of those sciences explored in lucid and convincing terms. Unfortunately, though, Theise then falls into the trap of all meditators: he attributes too much to his own experience. He even acknowledges this, but seems unable to hold back. That's understandable, but not helpful. The inherent problem of certituse based on one's own inner certitude is that it cannot be shared in language, nor can it be definitive. Theise also has not taken into account the qualitative difference between the revealerrs of the great religions (from Krishna and before to Baha'u'llah) and the sages who arise from time to time but make no claim to be mouthpieces of God. In fact Theise never addresses the question of whether or not his Consciousness is or is not what others call God. This whole aspect of the work belongs in another book. Here the exegesis is narrow compared with the broad panorama of its explorations of science.

This book's subtitle claims to be "A Scientific Theory of Connection, Consciousness, and Being."
But it isn't a theory of anything. It's a belief system of Everything. With a bunch of core ideas -- about Life in the Universe and our central place within it -- that pretty much anyone can find something to like and fervently believe.
If you believe in God or believe in Science. If you don't believe in God or believe that Science can't explain everything (or anything). If you're a Buddhist (like myself) or a Hindu or a Sufi or a Christian or a Creationist. If you're a quack like Deepak Chopra (the AIDS virus emits "a sound that lures the DNA to its destruction") or you're into philosophy or quantum physics or metaphysics or creativity or...

This book is difficult to put down.
In short, understandable, paragraphs and chapters Neil Theise takes us on a journey that shows us what is meant when people say “we are all connected.” Across the scale from the tiniest knowable particles and waves out into the cosmos, the author describes the science behind systems organization and leads the way to our understanding of how order always resolves from chaos. The complexity of the science of what we can’t see or measure directly yet is available to us when we recognize the foot prints of this order. This book helps us make larger sense of what we already knew, and we leave it feeling really good about ourselves and in awe of the magnificent mystery behind it all.

1.0 out of 5 stars Complexity Theory Nowhere to be Found
Reviewed in the United States on 14 July 2025
Format: HardcoverVerified Purchase
In no ways is this a book an investigation of complexity theory nor even a superficial introduction of it. There is essentially nothing of complexity theory reflected in the book, which comes in three parts:
1) an introductory twenty=page section which, again, does not even serve to introduce very basic fundamental ideas of complexity;
2) a survey of the increasingly microscopic levels of the organization of a human body, which is incredibly superficial and noninformative, but at least unobjectionable until the two physics sections, wherein the author makes a conspicuous demonstration of his abject lack of understanding of the last century of theoretical physics; and
3) an absolutely inane disquisition on zen buddhism and consciousness, complete with a revival of that old hippie trope about how the copenhagen interpretation "proves" his personal spiritual ideas.
this book is a personal spiritual manifesto relying of interpretations of physical theories with which the author is very clearly not even minimally conversant: "my-spirituality-is-true-because-quantum" written by someone painfully out of his theoretical depths.
do not waste your time with this drivel.

Reviewed in the United States on 1 February 2024
Format: KindleVerified Purchase
The first parts detailing the nature of complex systems were interesting. Some of the assumptions seemed flawed, especially dismissiveness towards the role of hierarchical influence. There seems little doubt that local interactions can explain emergent phenomena, but there is also clearly observable evidence in a significant portion of complex systems that a command and control center influences the nature of the system and what emerges.
The correlaries between quantum physics study derived dualities in nature and mystic traditions are old hash. The author adds nothing to the conversation except reckless leaps of unsubstantiated conjecture that seems more interested in forcing equivalency between rigorous scientific exploration and monastic traditional thought.
Subject matter was great. Author, not so much.

I had high hopes for this book, as I read everything I can on Complexity and Systems theory. The first few chapters started off well enough-- in fact, they offer a clear explanation for key elements of complexity. But when the author turns to quantum physics and Gödel, things quickly took an illogical turn. He ends up postulating the position of Idealism, that all consciousness comes from "Big "C" Consciousness" as he calls it. And the reasons he gives have been so thoroughly debunked by actual physicists (of which he is not one) There are so many better books that discuss consciousness and complexity that don't end up disguised as a religious text. I highly recommend "The Romance of Reality" as a better alternative.
