The Idea Machine: How Books Built Our World and Shape Our Future

by Joel J. Miller

Books are our first and most lasting form of information technology. Books preserve ideas, yes, but they also provoke new ones— they are true tools for thinking. In The Idea Machine, Joel J. Miller shows that books are one of the most important but overlooked factors in the making of our contemporary world. And they still have lessons to teach us. Polls indicate reading is on the decline, but as we deal with concerns about artificial intelligence and social and political division, the history of the book offers a path of understanding and patterns for engagement. They can even help us navigate what’s coming next. Starting with the surge of book culture in ancient Athens and then moving through the centuries, from monks and militaries to rebellions and the Renaissance, and even to more modern-day implications of books as tools of liberation and the novel’s impact on our humanity, Miller highlights the features and functions that make books indispensable to cultural evolution. Subject to its own periods of technological upheaval and social unrest, the history of the book can point us away from failed past responses and toward more fruitful adaptations that will benefit us all. The Idea Machine reframes the history of the book as the eye-opening story of humanity’s first mobile information device. Books do more than record thinking; they serve as tools to facilitate it. More than a history of the book as an object or a simple consideration of the literature it has contained, The Idea Machine is the history of the book as a technology that transformed the peoples and societies that embraced it, and which maintains a vital role in a world where technological advancements seem to render it obsolete and ideological division might render our shared future untenable.

A book about books, what more could a confessed bibliophile ask for?

Joel J. Miller, a man of many talents, but notably for me, the proprietor of the excellent Substack Miller's Book Review, nails it here. In The Idea Machine, Miller argues for the book as a form of information technology. He traces out the history of the book - all the way back to Socrates and his opposition to the book (gasp!) all the way up to current day and where we stand in the world of AI and LLMs.

The subtitle serves as the thesis: How Books Built Our World and Shape Our Future. A physically beautiful book filled with art and many full-page images add to the appeal.

I was captured from the start when I felt deeply the chapter on Socrates, whose challenges to the book as a technology made me question everything. Do I really not truly know anything? Are these books I own really just a flash in the pan of what I have imagined and then moved on? Do I not understand anything all the way down - the way a master could teach, but a book never could? Thankfully throughout the rest of the book, Miller restores my confidence in the goodness and utility of books.

A couple of last thoughts to conclude my review. First, it is amazing how inseparable the history of the book is with the history of Christianity. From gathering the letters of Paul into one spot and the emerging canon of the Bible, to the writings of Augustine, to monks in the Middle Ages, it is impossible to tell either the history of books without Christianity or to tell the history of Christianity without books.

Second, in the last section of the book, Miller looks at reading books through the lens of science (think Darwin and On the Origin of Species), the founding of America (including some bomb quotes from Thomas Jefferson on collecting books - the man was absolutely irresponsible in his spending on books), and through fiction as a powerful tool for liberation (think Uncle Tom's Cabin).

All this to say that I loved this book and I recommend to fellow book-lovers -- but also to the book skeptic.

"If we fail to recognize the biases of the tools we use, our tools will confound us."

"Without books, history is silent, literature dumb, science crippled, thought and speculation at a standstill. Without books, the development of civilization would have been impossible"

This is such an incredible book. Joel J. Miller digs into the history of the book and it is utterly fascinating. I had no idea the extent that Christians played in the development and preservation of the book. Joel masterfully ties together the physical object, the ideas therein, and the natural progression to today’s large learning models. This is a must read for lovers of the written word.

Miller has written a wonderfully accessible history of the book! As a history teacher, I greatly appreciated reading about so many great thinkers of the past and their interaction with books. Miller makes it very easy to visualize the progression of the book as well as its impact on how we live, read and learn, today. His tone is not condescending in the least. He offers original conversations from those of the past while sharing his thoughts throughout. The conversation enables the reader to also take part. I highlighted a lot and have many notes in the margins (and not just because he told me to).

As the subtitle suggests, it is a journey from the beginning (of books) to where we are now (internet, AI, etc.), and beyond. But Miller doesn't demand that he has the "answers" to the issues technology has presented in our time or that we may encounter in the future. He is an optimist throughout the book, which is refreshing in today's doom-and-gloom culture.

It might be a spoiler but the last line I underlined twice:
"The idea machine built our world and still shapes our future. Its users determine how."

The Notebook: A History of Thinking on Paper is a much better and more interesting book about this topic.

[DP · Rating 4 out of 5]

Wasn’t as personally interesting as I thought it would be, but well done nonetheless.

[Diana Manevskaya · Rating 3 out of 5]

Even though the book’s topic is very close to me, I found the book lacking. The writing is seems to be engaging, however, the author spends 80% of the book on ancient times, and then jumps through the rest of the history timeline.
And, he did not even mention Francisk Skoryna!
The book needs a good re-write and a fact check.

[Nastasia · Rating 2 out of 5]

The positive side of this book is that it is for the most part informative in a way that is engaging. The Idea Machine explores the book and its evolution through history by following the passing of time linearly. It starts with Socrates and from there on out travels to the current day.

The downside is perhaps a matter of personal taste, but I don't see where this book has had anything new to offer. So much time is spent in "the past" and while the past is indeed fascinating, the author had surprisingly little to add to mere historical exposition. I get it, the idea machine is cool. And it is. But where is the actual commentary? Where are the bad examples? History is defined by our villainy as well, why is it missing from the conversation? Where is the IDEA in the idea machine? Again, nothing new was added to the conversation, although the narrative voice wants to pretend that it is conversing with the reader.

Furthermore, the moment we reach the present... Pause. 99% of this book is historical facts with minimal discourse. The very final 1% is straight up LLM glazing. We spend a total of one final chapter in the present. Barely any in the near future, despite of the "and shape our future" in the TITLE. I actually was willing to give this book more credit UNTIL I reached the very last chapter. Sour taste in my mouth y'all. It made the whole book up until that point feel like a long exposition for A.I. and how cool it actually is. And while I do agree LLMs CAN be employed in various fields ethically and magnificently, let me explain why I am side eyeing Miller here. The first chapter of the book is a very long tangent into Socrates and his apprehension towards the newly employed "book" (or the early version of it, rather). We spend SO MUCH TIME on Socrates' bad faith hater ass that the moment we get to "and now... A.I." it is JARRING how the downsides and criticism of it are literally summed up in A SINGLE SENTENCE; to paraphrase "some people are against it/ afraid of it but lemme tell you of how cool it is here and there". NOT A SINGLE ACTUAL MENTION OF WHAT THE CIRITICISM IS! NOT.ONE! Absolute glazer behaviour. Absolute insult to academic essayistic. Absolutely and irrevocably insulting. What the fuck is this? Lazy and evasive and reeking of LARP. How the hell are we going to spend so much time on historical exposition just to glaze over A.I. when this WHOLE BOOK by the end feels like a very long-winded road to A.I. being the new form the "idea machine" takes on. Yes, provide useful and relevant uses of LLMs, but please address the naysayers with the same pathos you addressed Socrates' hater ass for a whole ass chapter. Maybe I am too critical, but I kid you not this made me side eye the author himself. The attitude behind this whole project just tanked in ONE SINGLE FINAL CHAPTER.

Anyway, recommend me more compelling and cohesive books on books. This was neither historical enough to be categorised and narrative history nor was it intercepted with enough discourse and analysis from the author to be called historical essayistic. It is mid as fuck. It is enjoyable for the most part, and it does provide a clear and even fascinating timeline for the idea machine, but my God the finale had it falling apart. I was literally overlooking the lightness of the conversation until it proceeded to take on a serious topic for our present and future only to "lighten in up" in the most low-effor and blase manner imaginable.

In an ironic turn of events this book seems to be proving Socrates right.

2.5/5 for the effort to timeline the history of the book somewhat.

𖣔 Хороша книга про.. книги ... Не можу сказати, що дуже оригінальна, однак цікава ... Здебільшого автор розповідає про історію книг, оформлюючи її різними роздумами щодо впливу тексту на людську свідомість ... При чому, він зауважує, що критика книгочитання існувала в усі часи ...

𖣐 Погоджуся з тим, що надання текстові власного змісту, навіть якщо його не закладав автор, є "фічою, а не багом", в цьому теж цінність читання ... Завдяки текстові думки не помирають з їх носіями, але зберігають і передаються ... Наголошується, що письмо - це форма мислення, за допомогою якої кристалізуються, шліфуються ідеї ... Окремі бали накину за нагадування про роль монахів у збереженні літератури та порівняння читання з некромантією (це моя метафора :}) ...

A brilliant deep-dive into the history of the book and its role in our cultural evolution.
Miller’s historical research is stellar, and he perfectly captures why books are, and will always be, indispensable.

This book feels written for readers who enjoy thinking deeply, not just consuming information.

[Julie Davis · Rating 4 out of 5]

This book is simply delightful in it's continual view of books as engendering thought, ideas, and "conversation" between the authors and the readers. I also never realized just how long ago people were pulling out century-old clay tablets to fact check their proclamations.

I enjoyed the first half the most but the rest was also interesting, most notably for me Harriet Beecher Stowe (I'm a big Uncle Tom's Cabin fan) and the fathers of the American Revolution.

[Adrian Neibauer · Rating 4 out of 5]

I will never look at the physical object of a book and the idea of books as technology the same way again. Joel Miller's book is a fascinating look at the history of books and how books have become indispensable to our cultural evolution. Miller is a book expert (author, editor, publisher) and The Idea Machine is well-researched and lovingly crafted book. Each chapter ends with insightful sections that go behind the scenes through the evolution of books. I highly recommend this book!
